​A335 P5 Large-Diameter Seamless Steel Pipe Φ914x12.7MM For Petrochemical Industry
 
Recently, ​A335 P5 Φ914x12.7mm large-diameter seamless steel pipes were shipped in batches. The order totaled more than 800 meters and nearly 250 tons. ASTM A335 standards, P5 alloy material, and specifications of Φ914x12.7mm were used for the integration of PetroChina’s Jieyang branch. The second joint project replaces the original ASTM A691 5Cr CL42 welded pipe.
 





 
The product features are:
(1) High precision, customized by combining two processes of thermal expansion and cold drawing;
(2) The length is long, and the length of a single pipe is more than 10 meters;
(3) The alloy material is difficult to process. As the latest typical application of large-diameter seamless steel pipes instead of welded pipes, it fully reflects our exquisite manufacturing level.
