Technical Briefings

In June, Edmonton Valve hosted a technical briefing, “Hose Selection and Troubleshooting,” packed with practical advice grounded in decades of experience helping engineers, operators, technicians, and buyers select hose for their fluid systems. We’ve posted the technical briefing online, along with resources attendees downloaded after the session. All the resources are free.

The briefing was led by Swagelok's Doug Nordstrom, Senior Project Manager for Hose at Swagelok Company. Nordstrom is responsible for the strategic direction and growth of the global Swagelok Hose Services Group. He’s been with Swagelok Company since 1995, holding a wide array of titles, including Product Manager for Hose, Valves, and Regulators; Project Manager for New Product Development; Marketing Manager for Chemical and Refining Products; and Manufacturing Engineer.

In previous posts about hose selection, we have emphasized the importance of choosing the correct end connections. In our June briefing, Nordstrom focused on the hose itself. He first reviews how a hose's four main components—core tube, reinforcement (braid), cover, and end connections—impact performance.

In industrial markets you’ll be choosing between metal core, fluoropolymer (or Teflon), thermoplastic or nylon, and rubber core. Each has clear strengths and weaknesses, and applying the wrong hose to an application can drastically affect hose life and safety.

The majority of the briefing is devoted to the importance of considering routing and hose motion, risk of static dissipation, variations in permeation, and metal hose fatigue. Each is a topic we may touch on in future posts here.

Often teams will replace hoses that fail with new versions of the same hose. That’s a riskier assumption than you might think. All too often, individuals who purchase hose for their facility don’t take crucial criteria into account. In addition, it’s rarely the case that every member of the purchasing team is thoroughly familiar with all the components of a hose.

Real-world examples illustrate the risks associated with incorrectly applying hose and the rewards that come from getting it right.

In one case, a tire company was experiencing failing hoses on steam lines to a tire press. The previous hose was a rubber hose that did not perform well at higher temperatures. In addition, the hose was not sized correctly, which caused kinking when the press moved up and down over 6 feet. The hoses would fail in under a month, leaking high temperature steam into the operation area.

The best hose for this application was determined to be a fluoropolymer core hose due to the compatibility with steam and ability to last in a high cycle application. Although there was some reluctance to make the switch due to the increased hose cost, the overall life of the hose increased over 20 times.
