中文简体Stainless steel BA/EP tube is high-purity and high-precision tube that is widely used in bioengineering, pharmaceutical, semiconductor and laboratory applications. It is also known as stainless steel gas tubing and pure gas delivery tube. The difference between a BA/EP tube and regular mill finish tube is that the BA/EP tube undergoes bright annealing, a heat treatment process that enhances its surface and provides resistance to corrosion in demanding environments. This is accomplished by applying hydrogen to the tube surface at 1900°F (1040°C) in a controlled atmosphere and then rapidly quenching it. This process eliminates any residual impurities from the surface and gives it a higher precision than other types of stainless steel tube.
This tubing is available with a variety of finishes and dimensions and is supplied with 3.1 specific test certificates, according to EN 10204, upon request. In addition, a full battery of ASTM bend and deformation tests is performed on the sanitary tube to ensure that it meets ASME SA249. This testing, combined with specific raw material requirements, Eddy Current testing at the tube mill, 100% borescoping prior to mechanical polish, and tighter OD and wall tolerances, ensures that you are getting top quality product.
Sanitary tubing is made from the same materials as general industrial grade stainless steel pipe but undergoes a series of additional processes, which include cleaning and passivation. This makes it more resistant to corrosion in a wide range of environments, and it is especially suited for use in the chemical, pharmaceutical, food and beverage industries. In addition to these advantages, sanitary tubing has excellent welding characteristics and is easy to fabricate and machine.
316L is an austenitic stainless steel with improved corrosion resistance to chlorides and acids. It is commonly used in marine applications and in coastal environments with high salt concentrations, as well as for medical equipment and implants. It is also commonly used in brewing facilities, because it has superior resistance to chlorine corrosion, pitting and crevice corrosion than other grades of stainless steel.
In addition to its corrosion resistance, 316L is highly ductile and has good weldability. This tubing can be cold formed, welded, machined and cut to size with relative ease, making it a versatile choice for many different applications.
