    China Wholesale Gas Pipe Manufacturers - Drill Pipe For Chinese Factories – Zhongshun

    Drill pipe is made from the welding of at least three separate pieces: box tool joint, pin tool joint, and the tube. The ends of the tubes are then upset to increase the cross-sectional area of the ends. The tube end may be externally upset (EU), internally upset (IU), or internally and externally upset (IEU). Standard max upset dimensions are specified in API 5DP, but the exact dimensions of the upset are proprietary to the manufacturer. After upsetting, the tube then goes through a heat tre...
