API grade tubing or casing nipple 

API Grade Tubing or Casing Pup Joint with Coupling High pressure fuel pipe is an integral part of high pressure fuel circuit. It is required that the fuel pipe should bear a certain amount of oil pressure and have a certain fatigue strength to ensure the sealing requirements of the pipeline. High pressure fuel pipe for vehicles mainly appears in high-pressure injection diesel engines and high-pressure injection direct injection gasoline engines, and can withstand the oil pressure required during engine operation. The oil pipe is composed of steel wire wound skeleton layer and oil and corrosion resistant synthetic rubber inside and outside. It is used for the transmission of hydraulic oil pipe of engineering machinery, submarine natural gas, oil, irrigation, steel plants, chemical plants and other media Classification: high pressure steel wire braided hose, high pressure steel wire wound hose, large diameter high pressure hose, steel wire (fiber) reinforced nylon elastomer resin pi…
