Gas rotary union

multi-passagefor pipe

The hammer unions which are produced on the basis of the absorption and digestion of the technologies transferred by American SPM and are used for connecting various pipeline include threaded connection type, welded type and hydrogen sulfide gas resisting type, with the specification being 1～4 and the cold working pressure being 7MPa～140MPa( 1000Psi～20000Psi). For the convenience of distinguish, the unions with different pressure grades have different color identifications and have obvious specification connection modes and pressure grade marks on the wing nuts. The specification and model of common union( threaded connection type): FIG100, FIG200, FIG206, FIG400, FIG402, FIG602, FIG1002 and FIG1502 The rated working pressure: 7MPa( 1000psi)～105MPa( 15000psi). 　Weld union specification : FIG20、FIG60、 FIG1002、FIG1502、FIG2002；rating working pressure : 14MPa（2000psi）～140MPa（20000psi） 　　Prevent sulfur weld union : FIG602、FIG1002、FIG1502、FIG2202、Tr120×6、Tr150×6、Tr180×8；rating working pressure : 35MPa（5000psi）～105MPa（15000psi） Credibility seal performance : 　　The seal ring is made of imported sizing materials through compression, so that its loading capacity and sealing property are improved greatly and prevent the joint from corrosion. The sealing types differ according to the pressure and application range. Quick installation: 　　Regardless of position and space, the wing nut and rigid self-locking type ACME thread are so designed that they can be quickly tightened and dismounted without using special tools.
