Air Products Lab uses vacuum insulated pipe from Technifab

Air Products’ Cryo-Trim deflashing laboratory utilized Technifab Products,Inc. (TPI) vacuum jacketed pipe (VJP) for its cryogenic piping requirements. Glenn Stroup, industry engineer, manages the Air Products cryogenic rubber deflashing laboratory in Allentown, PA. The laboratory utilizes liquid nitrogen (LIN) in an equipment process to embrittle molded rubber products while bombarding them with polycarbonate blast media in order to remove the more brittle flash extensions from the body of the molded rubber products. These products are primarily designed for use in major automotive, appliance,construction and medical applications. The process works well with such elastomers as silicone, EPDM, nitrile, SBR and a host of many other rubber compounds. The laboratory is utilized in order to determine whether the customer’s product is amenable to the process, to establish product quality, to determine equipment type & size, to measure LIN consumption and to determine overall system operating cost. After thelaboratory data is analyzed and the customer commits to the process, Air Products involves a VJP vendor for the recommended cryogenic piping layout, sizing and performance cost analysis.

Why Technifab Products?

Technifab Products is on Air Products preferred vendor list and comes highly recommended for all VJ piping quote requirements. TPI provides a quality product, reliable delivery, proper installation and backs it with an unconditional warranty. “They are reputable, honest and straightforward,” he adds, “and I am genuinely impressed with their overall organization.” What he likes best is that he can deal directly with the TPI staff and not through a representative or distributor network. That way he gets the most accurate information and prompt turnaround, which is extremely important. “When I contact TPI, they offer to have an account manager visit the site in order to get accurate layout measurements so that the accuracy, performance and cost of the piping system are guaranteed.” He adds, “They are extremely competitive on price and always meet delivery, quality and reliability commitments.”

Why VJP?

In many cases, Stroup prefers the use of VJ pipe in place of urethane foam piping. Installations with long piping runs and near continuous operation dictate the use of VJP in order to reduce heat leak, assure near saturated liquid delivery and minimize two-phase product flow problems. The net result is that the customer will consume less LIN product, maximize the accuracy & control of his process and improve the overall efficiency and productivity of his operation.

Vacuum insulated piping has become more cost competitive, overall, with urethane foam insulated pipe because it is designed, built and delivered to the customer site in pre-engineered sections, commonly referred to as spools, that require much less installation time and labor. On the other hand, foam insulated pipe must be cut, fitted, assembled, then the joints must be insulated and sealed on site, resulting in a very labor intensive installation. When all is said and done, the life expectancy and cost performance of foam piping is far less than that of VJP, usually resulting in an attractive payback and justification for selecting VJP.

“Technifab Products works as a partner with Air Products,” Stroup says. “Technifab is cost competitive, which works to Air Products’ advantage, because we have to be competitive in the marketplace in order to sell a turnkey solution.” Most important, he concludes, is the performance of the product. “Quality and accuracy of the pipe construction, installation and ongoing economic performance is extremely important. Technifab delivers every time!”
