ASTM A269-269M Precision Stainless Steel Seamless Pipe

Austenitic stainless steel seamless pipes for boilers, heat exchangers, condensers, instrument tubing, and oil service are manufactured via cold drawing or cold rolling processes. Key specifications and details are as follows: – Outer Diameter (OD) : 3-355.6 mm – Wall Thickness : 0.5-20 mm – Surface Treatment : Acid-washed (enhances corrosion resistance) or bright surface finish (meets high cleanliness requirements) – Application Scope : Suitable for pipelines in boilers, heat exchangers, condensers, and finned tube equipment. Widely used in boiler systems, instrument piping, oil transmission pipelines, and related industrial equipment fields requiring precision and corrosion resistance.
