WHY US

Welded pipe is mainly used for onshore and offshore oil/gas transportation, petrochemical, onshore and offshore structure.
SUNLION capacity is mainly based on China Top Class welded pipe group: CNPC & Sinopec.
The minimum order is 1 piece. All pipes will be 100% NDE tested, large diameter with heavy thickness is our strongest advantage.
