Product Applications
High-pressure seamless carbon steel boilers with minimum wall thickness and superheaters

Why choose us
We produce seamless mechanical steel tubing, in the hot-rolled condition, close to your finished part size, which makes it very competitive compared to other forging or machining processes. You may also purchase tubes in sizes recommended to clean up at finished part dimensions, which allows for optimum material utilization.
Package of carbon steel seamless pipe
Plastic caps plugged at the two sides of pipe ends
Should be avoided by the steel strapping and transport damage
Bundled sians should be uniform and consistent
The same bundle(batch) of steel pipe should be came from the same furnace
The steel pipe has the same furnace number,the same steel gradethe same specification
