2. The thread is processed by special CNC machine tool, high manufacturing precision, reliable use, long life;
3. Low cost, can be threaded to each other, easy to repair.
Pup joint is a kind of fittings commonly used in industrial pipeline connection. Can produce J55, K55, N80,L80, P110, L80-3CR, L80-9CR, L80-13CR and other steel grades of various specifications of flat, external thickened oil casing nipple.
