Flexible Corrugated Metal Leads are the choice when low diffusion rates and higher integrity are required. The inner liner is made from two plies of metal strip that are formed into a helical profile and resistance welded. Because it is not mechanically formed from tubing it is extremely flexible and does not contain the residual stresses like traditional mechanically-formed helical hose. A single stainless steel braid is used to further increase the working pressure. Because the lead is lined with metal, it will not diffuse small molecules.
Weldcoa’s Flexible Metal Cryogenic Hoses are the choice for highly flexible hoses with an excellent cycle life. The inner liner is made from a single strip of stainless steel that is welded into a tube and hydraulically formed into the flexible corrugated shape. Because it is not mechanically formed from tubing it is extremely flexible and does not contain the residual stresses like traditional mechanically- formed helical hose. A stainless steel braid is used to further increase the working pressure.
Quality control methods and meticulous attention to detail throughout the testing and cleaning process ensure that our customers will receive a leak-free lead that will provide years of service.
Weldcoa’s 1/4" 4600 PSI Stainless Steel Lined Flexible Metal Leads are most commonly used in high purity gas charging and discharging manifolds. These flexible leads are available for handling most common Industrial and Specialty gases such as Nitrogen, Argon, Carbon Dioxide, Helium and other inert and flammable gases and gas mixtures. Because they will not diffuse small molecule gases, they are ideally suited for Helium and Hydrogen discharge applications.
Note: Stainless Steel is not recommended for use with high pressure Oxygen.
Weldcoa’s 1/4" 3700 PSI Monel-400 Lined Flexible Metal Leads are most commonly used in high purity gas charging and discharging manifolds, where high pressure Oxygen is used. Monel-400 is used with Oxygen because it will not support combustion, like Stainless Steel. Monel-400 is compatible with the most common Industrial and Specialty gases including Oxygen, Argon, Nitrogen, Helium, Carbon Dioxide and Hydrogen.
Weldcoa’s 1/2" 3700 PSI Stainless Steel Lined Flexible Metal Hoses are an excellent choice when a large diameter is needed for high flow applications when used with small molecule gases such as Helium or Hydrogen. The most frequent use for these hoses is for tube trailer charging and discharging with Helium or Hydrogen. These flexible leads are available for handling most common Industrial and Specialty gases such as Nitrogen, Argon, Carbon Dioxide, Helium and other inert and flammable gases and gas mixtures.
Note: Stainless Steel is not recommended for use with high pressure Oxygen.
Weldcoa’s 1/2” 1186 PSI Stainless Steel Lined Flexible Metal Hoses are an excellent choice for atmospheric cryogen liquid and gas transfer. The most frequent use for these hoses is for the fill and vent lines for cryogenic cans or dewars.
Note These hoses are not for use with liquid Helium.
