DANGER

Chinese seamless pipe with splits and "weld" defects.

Hengyang Valin Steel Tube. Properly marked SA-53B/SA-106B with proper paperwork. Has splits in the material and apparent weld HAZ.

No way this stuff could of passed the listed hydro.

ALSO:

Chinese ERW pipe SA-53BE from 2 mills that split on the ERW seam 1000psi below hydro pressure on the MTR. Analysis showed it was low frequency ERW welded. This process has not been used in the rest of the world for 20 years.

Please be careful, this stuff is no bargin.
