JES Drill Pipes are made of modified AISI 4145H chromium molybdenum alloy steel. Each piece of drill pipe is 100% dimensionally inspected and the material is full length ultrasonically inspected. All connections connected to the pipe body by inertia friction welding are 100% inspected to conform to latest API standards.
