Stainless steel screen pipe (WEP pipe, EP pipe, BA pipe)

basic information

WEP Pipe: This is a high-quality EP pipe made using the VIM+VAR (Vacuum Induction Melting + Vacuum Arc Remelting) method, which reduces impurity elements and non-metallic inclusions in stainless steel to the utmost limit. Due to its excellent cleanliness, weldability, and corrosion resistance, it is commonly used in high-purity gas piping that supports cutting-edge industries, including semiconductor manufacturing equipment. Features: Extremely low Mn (Manganese), extremely low S (Sulfur), internal surface roughness Ry ≦ 0.7 μm Material: SUS316L EP Pipe: This pipe has undergone electropolishing (EP) on the inner surface of BA pipe, combining excellent corrosion resistance with a superior shine on the inner surface. EP pipes are high-end precision tubes that have been precisely cleaned in a clean room and individually packaged with end caps and double plastic wrapping, making them most suitable for high-purity gas piping. Features: Low Mn (Manganese), low S (Sulfur), internal surface roughness Ry ≦ 0.7 μm Material: SUS316L BA Pipe: This pipe is made from seamless stainless steel and undergoes special lubrication and high-precision cold drawing processing, followed by heat treatment in a bright annealing furnace. Compared to general JIS products, it has superior dimensional accuracy and surface roughness, making it suitable for high-purity gas piping. Features: Internal surface roughness Ry ≦ 3.0 μm Material: SUS304, SUS316, SUS316L
