Hoses and tubes are used for various purposes in a craft beverage production setting, including transferring liquids, washing containers and connecting essential pieces of equipment. Over time, this equipment can begin to show signs of wear and tear, or it can cease to be adequate for growing operations during times of expansion.

  Industry experts from companies specializing in these products weigh in on what breweries and distilleries should know about hoses, tubes and related accessories, plus how to choose the right options for your business.

Hoses and Tubes for Breweries

  Breweries benefit from using specific hoses to transfer and mix liquids at various levels and avoid contamination risks. All-in-one brewery hoses can be used to brew multiple beverages and eliminate manual labor tasks from mixing and transferring. Crimped hose fittings, clamps, gaskets, mounting bridges and hose barbs are hose accessories that help clean and maintain brewery vats and barrels.

  The most common materials used in brewery hoses are chlorobutyl, FDA UHMW, PVC, nitrile, silicone, EPDM and Teflon. Chlorobutyl hoses are common in brewery settings because they meet sanitary compliance standards and are ideal for non-oily applications and clean-in-place tasks. Yet it is crucial to ensure that the hoses you use can withstand specific temperature ranges and pressures. A food-grade, temperature-insulated, pressure-rated, 1.5-inch insulated brewer&#;s hose will accomplish many brewery tasks. But you might also look into highly rated hoses for resistance if they are placed in a high-traffic area where the hose could become kinked, twisted, or crushed. Tubing connects large components in a brewery to send waste products outside the production area.

Hoses and Tubes for Distilleries

  Craft spirit distilleries also use hoses to transfer products safely, hygienically and in a way that ensures excellent taste. Distillery hoses must meet industry sanitary requirements and FDA and USDA certifications. It is beneficial to use hoses specially designed for suctioning and delivering alcohol up to 96 percent.

  Clear tube hoses help ensure quality and cleanliness, and specific distillery hoses are designed to be odorless, so as not to alter the spirits&#; taste. A higher working temperature allows for steam sterilization after use. Using hoses with a chlorobutyl or UHMWPE tube and EPDM cover in a distillery setting is common. Distilleries may want to look for kink-proof and compression-resistant hose and tube products to maintain flexibility under cold temperatures.

Alliance Hose & Rubber Co. Offerings

  One company that specializes in this industry is Alliance Hose & Rubber Co., an Elmhurst, Illinois-based company that has been providing construction and industrial supply products since . It serves a variety of industries, including beverage, chemical, transportation and construction, with products that include industrial hoses, flexible tubing, couplings and fittings. Rob Williams, the sales manager for Alliance Hose, told Beverage Master about how craft breweries and distilleries use his company&#;s products.

  &#;We currently serve breweries in multiple ways,&#; Williams said. &#;One way is custom-cut and coupled hose systems, including a product hose, chemical hose, washdown and tubing to mate with the variety of connection options available, standard and special fittings, pumps and hose reels. Alliance Hose also serves breweries, distilleries and wineries with education on product knowledge and safety in person, at conferences and through webinars and podcasts.&#;

  He said nearly all Alliance Hose&#;s beverage products are also used in distilleries.

  &#;We do focus on the right hose for the distilling process, from front-end mash to the final high-proof product to be transferred,&#; Williams said. &#;Distilleries vary on what they like to use best. We just like to share insights and any additional knowledge that will help make their final product the best it can be.&#;

Kuriyama Offerings

  Another industry leader in industrial hoses, couplings and accessories is Kuriyama of America, Inc., which opened for business in and is located in Schaumburg, Illinois. The Kuriyama of America group of companies has eight subsidiaries and six distribution centers. It works through numerous distributors to provide thermoplastic, rubber and metal hose products and accessories, including couplings and fittings, for commercial and industrial applications.

  Tim O&#;Neill, marketing manager for Kuriyama, told Beverage Master Magazine that his company is best known for its high-purity, food-grade Kuri Tec® brand, clear vinyl hose and tubing products within the brewing industry. Most breweries use clear vinyl tubing, and Kuri Tec is a popular choice because it effectively maintains the purity of the materials that  the hose and tubing are made from. He explained that to ensure a high standard of quality and purity, Kuri Tec hose and tubing meet a wide range of safety standards, such as FDA, USDA, 3-A, NSF and USPS Class VI. To ensure compliance with these standards, Kuri Tec makes its own materials to manufacture its hoses and tubing, allowing for complete quality control.

  &#;An important consideration brewers should keep in mind when purchasing hoses and tubing is to understanding the difference between products that are simply considered &#;food grade&#; and ones that are considered &#;high purity.&#; Often, brewers will hear the term &#;food grade&#; and assume the hose will meet all their needs. However, the term only implies the product meets the basic standards of the FDA CFR 21 for food contact safety. It does not ensure the hose will not impart taste or smell on the ingredients or beer that pass through.&#;

  O&#;Neill said that the 3-A Sanitary Hygienic Standard, which originally started as a quality standard for the dairy industry, is quickly gaining acceptance in the brewery industry as the standard of choice to ensure the safety and purity of transferred materials. 

  &#;The 3-A standard defines additional criteria, such as ensuring low-extraction materials, as well as ensuring cleanability by reducing areas where materials can become stuck, potentially resulting in bacterial growth. Hoses, fittings and assemblies meeting the various 3-A Sanitary Standards have become a requirement at many craft and commercial breweries.&#;

  More recently, Kuriyama introduced a rubber &#;vat to vat&#; transfer hose under the Aflagomma® brand, called &#;The Brewt&#;.&#; In addition to meeting the 3-A standard for rubber purity, the hose provides a more flexible alternative to the heavy rubber hoses commonly used at larger breweries.

  &#;We found a lot of the smaller breweries were using the same heavy rubber hoses initially designed for larger commercial breweries,&#; said O&#;Neill. &#;The Brewt was designed to exhibit a similar ability to withstand the dragging and high-temperature cleaning to which these hoses are exposed, but to be light and flexible enough to work well in smaller craft breweries that may have space limitations.&#;

Common Hose Issues Among

Breweries and Distilleries

  Williams from Alliance Hose told Beverage Master Magazine that the most common problems that breweries and distilleries encounter with their hoses all relate to safety. These problems include pressure and temperature issues, trip hazards and finding the proper hose, tube and fitting for a particular application. These problems exist with product, gas and chemical transfers.

  &#;We address these needs by asking the right questions and recommending the safest option for that particular application,&#; Williams said. &#;We are not a click-of-the-mouse and a shopping cart. We ask questions and connect on a personal level with the beverage community. Concern for our customers safety and quality of their product is a high priority.&#;

Choosing the Right

Hoses and Accessories

  There are certain questions that brewery or distillery owners should ask themselves when buying a new hose. Williams from Alliance Hose uses the acronym STAMPED to get essential information from customers and provide the correct hoses and fittings for the application.

S    (size) What is the hose I.D./O.D. and length needed?

T    (temperature) What is the max fluid temperature inside the tube? What is the external atmosphere temperature?

A    (application) Where and how is the hose or tubing being used? What are the surrounding conditions?

M   (media) What is going through the hose or tube?

P    (pressure) Pressure product is being conveyed?

E    (ends) What fittings are required to make the connection?

D    (delivery) When do you want the hose or tube?

  &#;If we don&#;t have all the information we need, we will press in to gather those details as they are important to the hose system and overall brewing process,&#; Williams said.

  While discussing the topic of craft beverage hoses and tubes with industry experts, we found that there are few, if any, new technologies or innovations for brewers and distillers to be aware of. These are well-established and reliable products that get the job done, but there are differences in product quality and customer service to keep in mind.

  &#;I recommend talking to a hose professional instead of just relying on e-commerce to provide you what you think you may need,&#; said Williams from Alliance Hose. &#;I&#;m always available to talk product knowledge and especially safety.&#;

  O&#;Neill from Kuriyama said that the most important thing a brewery or distillery can do is ensure they have a good local hose supplier they trust to provide them with the right product for their needs.

  &#;The difference between using the right hose and one not best suited for a particular application can result in premature hose failures, causing lost production time,&#; O&#;Neill said. &#;Having a hose supplier that will understand your particular needs, rather than simply providing whatever hose they happen to have on the shelf, will improve overall operations.&#;

Modern municipal drainage systems require long-lasting, sturdy materials, and careful installation to protect the wellbeing and stability of the community. And in order to achieve this, choosing the right distributors of drainage pipe supplies for the project is paramount.

In order to ensure the reliability and quality of purchased materials, knowing which questions to ask a drainage pipe supplier is particularly useful. This will enable you to make a confident decision when choosing a sewage pipe distributor as it will give you more insight into the company and its approach.

What should I ask a municipal drainage pipe distributor?

Before you decide to work with a pipe distribution company, you should learn as much as you can about the materials they offer and all other aspects of their services. And the easiest way to do that is by asking the right questions. Here&#;s what you should ask your municipal drainage pipe supplier:

1. When was your business founded?

Experience is one of the most important characteristics a water/wastewater distribution company can have. Naturally, it isn&#;t the only factor that influences the quality of services the distributor offers, but it can nevertheless be an indication of a respected and dedicated company. Make sure to check when the prospective supply company was founded and feel free to ask them about their previous experience and projects they have been involved in over the years.

2. Which pipe manufacturers do you work with?

The quality of the offered materials should be a priority when deciding on a piping company for a municipal drainage system installation project. You should be able to purchase a wide array of piping materials from a great number of industry-leading manufacturers, whether you need a quality HDPE pipe, surface drainage equipment, PVC fittings, or any other drainage materials. This question should be one of the first you should pose when deciding on the company to hire.

3. Are you a member of any industry associations?

When a pipe distribution company is involved in local and national water/wastewater associations, it usually means that they are dedicated to meeting industry standards and providing the highest quality of materials and services to their customers. If you wish to make sure that the pipe distributor is reliable and client-focused, ask them if they are members of organizations such as AWWA, WASDA, the Rural Water Association, and others.

4. Where can I learn more about municipal drainage systems?

A respectable piping distributor should be willing to offer relevant and useful resources about municipal water and drainage systems and the various industry projects and associations. Check whether they provide such information on their website or at the customer&#;s request.

5. Do you offer nationwide shipping?

While you may be able to find a dependable supplier near you, it isn&#;t always possible to get the right materials locally. In that case, choosing a pipe distribution company that ships their materials across the nation is your best bet. Make sure to check their delivery speeds and fees, and whether they serve your particular location.
