We've been exploring and developing upon producing various oil drilling tools including Drill Pipe, Drill Collar, Heavy Weight Drill Pipe, Kelly,Pup Joint and so on.
Our API drill pipes are of high physical property, for their strictly controlled processing of sulphur and phosphorus.To ensure the materials to meet even surpass the requirements of API Specification, heat treatment is on the basis of the actual chemical analysis of each heat of steel.Strict full-length inspection especially on the weld-neck region ensures the drill pipes are of no defects.
