Stainless steel clean pipe (EP) pipes are mainly used in high-purity gas production, pharmaceuticals, semiconductors, biology and other industries that require high cleanliness. The pipe needs to be nitrogen purged and packaged in a clean room to meet the requirements, and the inner surface of the pipe is in an electropolished state (EP).
Main material: TP316L, 316L (high sulfur), 316LSS, etc.
Production standard: ASTM A269/ASTM A270/ ASME A270-BPE/ EN10216-5/ EN10305-1/ISO 1127.
(1) Features: On the basis of high-quality BA pipe, the inner surface is electrochemically polished, then purified with high-purity water, and finally packed with nitrogen. This process requires the diameter of the stainless steel pipe to be controlled within a tolerance of ±0.02mm (0.1%), the length of the stainless steel pipe to be controlled within a tolerance of ±0.05mm, the straight line curvature not greater than 0.1mm/m, the surface roughness of the finished EP pipe Ra≤0.2μm, concentricity Controlled within the tolerance of ±0.01mm, the mechanical properties control range can be adjusted and controlled to the hardness HRB (75~580), the strength δb and the elongation Ψ; the tube is made by solid solution treatment in a reducing atmosphere of heat treatment.
(2) Delivery status: electrolytic polishing (EP) electrolytic polishing
(3) Inspection and packaging instructions: eddy current non-detection, water pressure test; coding PE bag, cap, shock-absorbing packaging, dust-proof packaging, protection and protection
