From 2013 to 2015 year, we awarded the world`s largest P91 order from Reliance (single PO 8,000 tons P91), the final additional quantity together is up to 16,000 tons, Plus CS 11000 tons. Entire projects P grades are from Yangzhou Chengde
We can produce lots of the Alloy Steel Pipe that used on the Petrochemical and Refinery project and Gas cylinder project, such as the 4130 Steel Pipe, 4140 steel pipe,4142 steel pipe,4145 steel pipe,4147 steel pipe, P11 steel pipe ,P12 steel pipe ,P22 steel pipe ,P91 steel pipe,P92 steel pipe ,P5 steel pipe, P9 steel pipe and P36 steel pipe
Yangzhou Chengde Steel Pipe (YC) has been growing to a leading large diameter Seamless pipe manufacturer with production range 8``-48`` in OD and wall thickness from 9.53 mm up to 140mm.
YC had established the post-doctoral research station since 2006 focusing on new material development such as P92, P91, X80. More than 29 kinds of new materials and products have won the national and provincial prizes from 2006 till now.
