With competitive price and timely delivery, Yongchang sincerely hope to be your supplier and partner.
Process design data
Know the temperature, pressure, maximum use pressure, maximum use temperature, minimum use temperature, corrosiveness, quality, vapor pressure, inlet and outlet volume, etc. of the medium to be stored in the storage tank. The same resin, different uses, different prices. The thickness of FRP shell varies by quality and price. These data are collected as design basis data.
Selecting materials
For the storage of chemicals, the corrosiveness of the medium is an important factor in considering the storage material. Corrosive materials can be selected from enameled vessels and glass-lined vessels depending on the working pressure and working temperature. Steel pressure vessels can also be lined with rubber, lined with porcelain, lined with PTFE, etc., to improve the corrosion resistance of the vessel.
Types of storage tanks
The choice of carious storage tank includes horizontal or vertical and head type. According to the requirements of the process conditions at the time of design, from the national standard series of containers, choose the type of container that matches the parameters of the process conditions.
FRP storage tank steel frame: good or bad material, choose expensive, choose poor cheap. The same angle steel has three or four different prices, that is, the same steel and material thickness, product quality is also different.
GRP storage tank water distribution section: fixed and rotary, consisting of dry pipe, water distribution branch pipe and nozzle or rotary distributor.
GRP tank water receiver: fixed pipe water distribution, due to the use of nozzle, the sprayed cooling water will be pumped out from the cooling tower by the fan, constituting a water loss and purification environment. Water splash loss of the cooling tower.
Measurement of dimensions
The appropriate volume of the storage tank is determined by taking into account the type of tank, the nature of the stored material, the size of the available site, the handling capacity of the equipment and other factors. After the initial determination of the appropriate volume of the storage tank, the total volume of the material to be stored divided by the value obtained from the appropriate volume of the storage tank, that is, the required effect after rounding.
After the volume of the storage tank is determined, the diameter and length can be determined. The length to width ratio should take into account the appearance of beautiful and practical, and to adapt to the size of the workplace.
The above is the FRP pipeline exporter WEITONG introduced the selection principles of FRP storage tanks. We hope there is practical help for everyone to buy storage tanks.

Crosslinked Polyethylene Vs. Fiberglass Reinforced Plastic Tanks
Purchasing a high-performance chemical storage tank is a significant investment for your company, and choosing the right tank for your needs isn&#;t always an easy decision. If you&#;re deciding between a fiberglass reinforced plastic (FRP) tank and crosslinked polyethylene (XLPE) tank, be sure you understand the differences between them and know what to expect in terms of cost, maintenance, service, delivery times, and protection.
FRP tanks are coated with an interior chemical resin. Their structural layer is composed of chopped glass fiber or filament-wound fibers and resin. XLPE is a thermoset resin specifically engineered for critical applications like chemical storage.
Let&#;s explore seven important benefits of XLPE over FRP chemical tank systems. Evaluate these benefits thoughtfully as you select your next chemical storage tank system.
XLPE Offers Seamless Construction for Greater Strength
Fiberglass Reinforced Plastic tanks are filament-wound or hand laid up. Fibers are intertwined into a nexus veil that is wound onto a spool. In this spool, the fibers create a fiberglass layer with added resin, which keeps them bound together. Fiberglass tanks are constructed with seams (due to the winding).
This method of manufacturing inherently creates the opportunity for weak points that are vulnerable to leaks. In addition, FRP tank manufacturers add the top and bottom of the tank post-production, further increasing the risk of leaks.
Conversely, crosslinked polyethylene tanks are rotationally molded, producing a one-piece construction with no vulnerable seams. As opposed to fiberglass tanks, rotationally molded tanks are a homogenous, one-layer construction. This one layer construction eliminates potential weak spots in the tank structure and eliminates wicking or delamination that can occur from chemical attack or poor construction.
Chemical Wicking into the Tank&#;s Walls
Because of the structure of fiberglass, harsh chemicals can wick into fiberglass tank walls over time, compromising the tank life. Eventually, the chemical resin barrier on the interior wall can be compromised, and the chemical can make its way into the structural area of the tank. This structural area usually isn&#;t designed to provide the chemical compatibility that the interior resin provides. As a result, the fibers can begin to break down, and eventually, the tank fails.
While there are repairs that you can sometimes make, they&#;re usually only temporary. Eventually you will need to replace your fiberglass tank.
That&#;s one of the reasons that most fiberglass tanks don&#;t have the same warranty Poly Processing provides for our corrosion resistant tanks. Even the harshest chemicals can&#;t seep into high-density crosslinked polyethylene tank walls.
Cost of Tank Ownership
Fiberglass tanks are more costly than crosslinked polyethylene tanks, sometimes three to five times more. Delivery times can be three to four times longer as well. FRP storage tanks have a higher upfront cost in general, and the lifetime cost of ownership is higher. FRP tanks require more maintenance than crosslinked polyethylene tanks, costing you time, resources and money.
Because FRP tanks are painted or have a gel coat on the outside of the tanks, they need to be recoated on occasion. This is especially true for outdoor tanks because the fiberglass requires UV protection to prevent additional wear. XLPE tanks never need to be painted or coated, because the entire wall has UV additives throughout the tank.
Special Handling Considerations
Fiberglass tanks are inflexible, which makes them vulnerable to cracking. Extreme care must be taken anytime you move an FRP tank, especially during installation. As a result, these tanks often sit on a special wicking mat so that any leaks in the bottom of the tank can be easily seen as the chemical spreads throughout the mat.
Crosslinked polyethylene tanks are much more durable, and can easily be moved at any time. In fact, our durability testing drops filled tanks from as high as 45 feet above the ground&#;without splitting or leak leaking.
Molded Tank Fittings vs. Traditional Attachments
All FRP fittings are added onto the tank after production, which creates the opportunity for leaks at the attachment point. Poly Processing&#;s IMFO® (Integrally Molded Flanged Outlet®) fitting prevents this problem because the fitting is integrally molded into the tank itself. It&#;s not an attachment, but a single part of the chemical tank. This innovation removes potential stress points and allows no opportunities for leaks.
NSF/ANSI 61 System Certification
Poly Processing is committed to ensuring that our polyethylene chemical storage systems meet industry standards and are NSF/ANSI 61 certified. In fact, among chemical storage tank manufacturers, Poly Processing is the only one with a complete chemical storage tank system that is NSF/ANSI-61 certified. Currently, we have NSF 61 Certification for 38 of the most popular water treatment chemicals on our XLPE tank systems. Additionally, our certifications cover XLPE tanks with the OR-® System.
Most FRP tanks hold the basic NSF/ANSI 61 certification for only one specific application, potable water.
Delivery Lead Times
We know that delivery times are critical to our customers. That's why we work diligently to ship every order within 8-12 weeks. Most FRP tank manufacturers and poly tank manufacturers are giving their customers a 24-40 week shipping window based on lack of raw material sourcing, Covid-19, etc. At Poly Processing Company, we can deliver your product in one third of that time.
Before you order an FRP tank, make sure the manufacturer gives you the price and the lead time up front. Otherwise you could be in for a rude awakening.
Trusted, consistent, and expeditious, Poly Processing&#;s rotationally molded crosslinked tanks are by far the toughest polyethylene tanks offered to the chemical market. With our 6-8 week delivery window, we strive to deliver peace of mind and an ease of business to each and every customer.

Shipping containers are an essential part of the global economy. They allow goods to be transported quickly, safely, and efficiently from one side of the world to the other.
Made from a durable steel alloy, these containers can withstand harsh conditions on land and at sea, allowing for repeated use over many years. In addition to their strength and longevity, shipping containers are highly customizable and can be easily adapted for different applications.
With all of these benefits, it's easy to see why shipping containers have become such an integral part of modern trade. Whether you're shipping machinery across the ocean or transporting household goods halfway around the world, you can rely on these versatile containers to get the job done safely and securely.
In order to transport goods effectively and efficiently, engineers need to design effective shipping containers. Through careful planning, attention to detail, and an understanding of the needs of both shippers and customers alike, engineers can help ensure that goods get where they need to go safely and securely.
Shipping Container Design
When designing a shipping container, many considerations must be taken into account. First and foremost, the container must be strong enough to withstand the rigors of transport on land, sea, and air. In addition, it needs to be compact enough to fit easily onto rail cars or trucks but also large enough to accommodate a wide variety of goods. This requires a careful balance of material thickness and construction techniques that strike a balance between durability and weight.
Furthermore, the design should incorporate space-saving features such as foldaway bays or stackable decks to maximize efficiency when loading and unloading cargo. Ultimately, the goal of any shipping container design is to create an effective vessel for transporting goods quickly and safely across great distances.
Shipping Container Material Choice
When designing a shipping container, engineers must think carefully about the materials used. Not only should these materials be strong and durable to protect whatever is being shipped inside, but they should also be lightweight in order to maximize efficiency. Different materials will have different advantages in this regard.
Shipping containers can be built using a robust mix of materials that provide both strength and durability. From durable metal frames to impact-resistant plastic walls and weatherproof coatings, these shipping containers can withstand significant wear and tear as they traverse the globe delivering goods to customers. In addition, many shipping containers are equipped with features such as cargo nets, built-in locking systems, and air vents to further improve the safety and security of their contents.
For example, high-grade steel is a common choice for shipping containers because it is highly resistant to corrosion and impact damage. At the same time, lightweight aluminum can help to reduce fuel costs by making transportation more efficient. Other options, such as recycled plastics or new composite materials, may offer additional benefits such as sustainability and reduced environmental impact.
Thanks to advances in engineering techniques and materials science, designers are now able to use lightweight materials like carbon fibers and advanced composites to create solid yet resilient structures that are more resistant to external influences like wear and tear or damage from weather. Additionally, new types of junction points allow for more varied configurations inside the container to better accommodate specific loads or functions.
These developments have contributed greatly to a new era of effective and innovative shipping container design that continues to advance today. Ultimately, choosing the right material for a shipping container depends on a range of factors that must be carefully considered by engineers in order to create the best design possible.
Real-World Study and Example
A recent study has found that shipping containers made with composite materials can weigh up to 80% less than traditional containers. In this research, a new design for a 40-foot shipping container made of carbon fiber laminates was created. The tare weight of a traditional shipping container of the same size is kg. However, the weight of the composite container designed in this research is only 822 kg.
Such a dramatic weight reduction would have numerous benefits for the shipping industry. First, it would reduce fuel costs by allowing more containers to be carried on each trip. Second, it would reduce wear and tear on vehicles and equipment, as well as reduce greenhouse gas emissions. Third, it would allow shipping companies to increase their profits by increasing the number of containers they can ship each year.
TenCate Advanced Armor USA, a company specializing in the production of lightweight armor for military and law enforcement applications, has teamed up with Air Cargo Containers, LLC of Phoenix, Arizona to manufacture air cargo containers using TenCate's advanced composite materials.
The resulting containers are up to 42% lighter than their aluminum counterparts while still providing superior strength and durability. The lighter weight of these containers results in significant fuel savings for airlines, as well as reduced wear and tear on aircraft cargo-handling equipment.
One material choice that engineers can take advantage of is fiberglass-reinforced plastic (FRP).
FRP for Shipping Containers
When it comes to shipping containers, durability and strength are two of the most important considerations. Heavy loads and rough handling can take a toll on less durable materials, increasing the risk of damage or failure. In this context, fiberglass-reinforced plastic stands out as an excellent choice for shipping containers.
Durability
When it comes to shipping containers, one of the most important considerations is durability. After all, these large and often quite heavy objects need to be able to withstand a great deal of wear and tear throughout the shipping process, as well as any rough handling that may occur during storage or loading. In addition, it is important that shipping containers maintain their structural integrity throughout their lifespan in order to ensure the safety and security of the cargo they are transporting.
In this regard, fiberglass-reinforced plastic is an ideal choice. This material combines the high strength and resistance to impact typical of plastics with the durability and shock absorption properties of fiberglass. As a result, FRP containers can be used in a wide variety of harsh conditions without losing their structural integrity or exhibiting signs of wear and tear. Additionally, when compared to metals like steel, aluminum, or even wood, FRP containers tend to require much less maintenance over time.
Lightweight
When it comes to shipping containers, one of the most important factors is weight. Due to the scale of modern transportation systems, each unit needs to be as lightweight and compact as possible to minimize fuel costs and maximize efficiency. Additionally, since so many containers are now transported using trains or trucks, reducing their weight can help improve safety by minimizing wear on vehicles.
FRP is lightweight compared to many other common materials used in container construction, such as steel or wood. This makes it easier to move and transport the containers, reducing costs and increasing efficiency. In addition, because it is relatively thin and flexible compared to other typical container materials like steel or aluminum, FRP can be molded into complex shapes that enable it to conform to the contents of the container more easily.
Overall, FRP is a great choice for shipping containers due to its many benefits in terms of strength and durability. Whether you are transporting food or construction materials across long distances, you can rest assured that your items will arrive safely when packaged in an FRP container.
