♦ The details of Integral Heavy Weight Drill Pipe as follows:
1. Material: AISI 4145H Alloy steel, Non magnetic steel, etc.
2. Use: It is mainly used between dill collar and dill pipe to ease transition stress concentration and reduce the rate between contact area and outer wall wear, which can effectively prevent the pressure sticking.
3. Standard: API Spec 7-1 or SY/T 5146 Standard.
4. Inspection&Test: When producing, traceability are maintained from the receipt of raw material to completion of final products, and serial numbers are die-stamped on each workpiece body. During each manufacturing process, inspection and test are performed.

2. drill pipe tool joint production process:
3. drill pipe friction welding process:
1.Before order to be confirmed, the raw material of pipe and tool joint body should be booked from famous big steel enterprises in China.
2.Checked by our QC staff and factory own laboratory.
3.Every drill pipe has nondestructive inspection , cleaned and breach oil before packing.
4.Before delivery clients could send one QC or point the third party to check the quality such SGS, BV or others.
1. The drill pipes will be packed into bundles as 3x3, 3x4, 4x4 etc. and loading into containers after black painting and thread protectors installation.
2. For 20’ container, the max loading weight is 21 metric tons
3. For 40’ container, the max loading weight is 27 metric tons.
4. Usual loading port is XINGANG port in Tianjin, main port in north of China.
♦Drill pipe usage notes:
1.New drill pipe should be pasted thread oil before connection
2.Make up and break at least 3 times before drilling
3.Hard bending and plastic coating can be processed according to costumer special requirement
1. Strictly according to ISO9001 standard.
2. If you found to have quality problems, within one month of the package returned.
