Stainless steel bright annealed tube is broadly used in applications (such as instruments, equipments, machinery) where requires high cleanliness inside surface, high precision dimensions, high corrossion resistance in various industries such as gas, chemical, shipbuilding, automobile, and so on.
Our bright annealed tubing is used as high purity stainless steel tubing for applications where high purity and high performace is required, we have rich experiences of manufacturing our BA tubes as high purity gas tubing to many oversea projects. Besides BA high purity tubing, our factory also produces Electropolished ultra-high purity(UHP) stainless steel tubing.
Lab gas piping is one of the main application of our high purity gas tubing. Younglee supplies Lab gasing tubing with high smooth inside and outside surface, the surface roughness of inside is Max. 25RA (RA 0.6 microns). And Younglee's Lab gas tubing is oil free, which can greatly ensure the purity of the gas and air.
