Yangzhou Chengde (YC) is one of the best steel pipe manufacturers in the world, and the production diameter from 8" to 48" in OD and wall thickness from 9.53 mm up to 140mm. We can produce the gas cylinder steel pipe and mechanical steel pipe according to the ASTM A519 standard. In recently 10 years, we have been produced and sold about 200000 tons 4130, 4140, 4142, 4145 and 4147 steel pipe to China, Korea, South East Asia, Middle East, North America and Europe.

Chengde invented the Piercing-Rolling joint production technologies with its own patents and intellectual properties. The process is unique from others with following edges:
1 Stable, fast and continuous
2 Flexible on non-standard sizes
3 Swift tooling switching
4 Uniform mechanical properties and dimensions in longitudinal& transversal directions
5 Better surface condition thanks to shorter rolling time & good tooling quality
6 Three-roller/five racks sizing machine can avoid inner hexagon significantly
Our products can meet the standard requirements as follows:
