Product Applications
Mechanical applications
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
