Standard: API 5D
Specification: OD: 2 3/8”-6 5/8”
Steel Grade: E75, X95, G105, S135
Internal Coating: TK34, TC2000, TC3000
Hardbanding: ARNCO 100XT, 200XT, 300XT, BOTN3000, ARMACORM
Length: R1: 5.49-6.71m R2: 8.23-9.14m R3: 11.58-13.72m
Usage: As the major part of drill stem, drill pipe connected with Kelly and drill collar, which is used to put torque to drill bit, and drill collar.
Description:
The Pipe Body in conformance in API.5D with serious inspection in Plant. Tool Joints are made of AISI 4137H premium alloy steel fully Q&T with IPSEN furnace. All tool joints should be inspected by fluorescence magnetic particle and ultrasonic method.
The welding between drill pipe and tool joint is machining with Friction welding machine. The welding process by means of computer control is swift and steady going. Weld zone is quenched and tempered through induction heating process, which is controlled real time by computer.
