1.Overview
The high-pressure straight pipe is made of high-quality alloy steel and the end is connecled by the union. Its specifications have 2", 3" and 4" and cold working pressure is 42MPa to 105MPa(6000psi-15000psi). The high-pressure straight pipe includes ordinary integral type, integral type with shoulders and split type high-pressure straight pipes. The length depends on the demand of clients.
2.Structure of high-pressure straight pipe

Split-type high-pressure straight pipe is popular in the United States or countries that habitually use American products.
Integral high-pressure straight pipe with shoulders is installed at one end of the three-jaw nut. Specially designed shoulder (see the left end of the picture above), can make the three-jaw nut not fall off or slide down to ensure its use safer. At present, integral high-pressure straight pipe with shoulders are becoming more and more widely used.
