Our company supply high quality and API certified tool joint for drill pipes' connections. These tool joints are turned, bored and faced prior to heat treatment by the quench and temper process to produce a uniform microstructure, high ductility and other mechanical properties in accordance with API specifications. The heat treatment is done under controlled atmosphere for consistent quality. The tensile and impact properties are verified by destructive testing for each process batch tool joints to ensure the quality of the tool joints can meet the requirements in API specifications. Every tool joint is subjected to non-magnetic inspection and ultrasonic inspection to ensure there are no defects in the joint tools.
The mechanical property of the tool joint is as follow.
Tensile Strength: More than 827. 4 MPa
Yield Strength: More than 965 MPa
Elongation(%) more than 13
Brinell Hardness: More than 285 HB
Impact Text: More than 54 J
5-1/2"H tool joint
