New Marine hydraulic fittings -GS flanged pipe joints without welding
In marine vessels and offshore engineering ( such as offshore drilling platforms ) Hydraulic Equipment Factory has been the use of a pan , and its increasingly large proportion . Fittings hydraulic system safety and reliability is crucial, conventional welded flanged pipe joints, assembly and disassembly problems , maintenance difficult. Especially in the work of the vessels and rigs , and if found defective pipe joints , should the need for welding , is often impossible. Therefore urgent to disassembly is simple, reliable , without welding flange connection Hydraulic ferrules . Therefore, no welding GS flanged hydraulic : a fitting tube came into being , the countries have already put into use. Currently GS -type non-welded hydraulic fittings , its technical specifications are as follows : nominal pipe diameter: small 20 a small 165mm, wall thickness 5 mmo working pressure : 42MPa its basic structure has the following two ways: one is with a 37 " flare non- welded flanged pipe joints , another is a ring with a metal hose fittings without welding flange
