VSSJAF {C2F} double flange loose tube expansion is introduced
Double flange loose tube, dowel joint model VSSJAF (1999 standard) or C2F (2002), by the flange loose tube expansion joint and short of pipe flange and dowel screw components. It can deliver the fitting of a pressure thrust (blind plate force) and compensation pipeline installation error, cannot absorb the axial displacement, it is mainly used for connection to a loose tube pumps, valves and other accessories.
VSSJAF/C2F type double flange loose set of dowel joint advantages: simple and convenient installation, convenient valve installation, affordable pipeline axial tension.
VSSJAF/C2F type double flange loose set of dowel joint features: double flange connection method.

VSSJAF {C2F} double flange loose tube expansion of scope of application
Double flange loose set of dowel joint is applicable to transport seawater and freshwater, hot and cold water, drinking water, sewage, oil, fuel oil, lubricating oil, refined oil, air, gas, temperature is not higher than 250 degree steam and granular powder, etc.

VSSJAF {C2F} the performance characteristics of double flange loose tube expansion
Pine set of dowel joint is on the basis of the flange joint loose tube compensation add short flange pipe and dowel screw, joint type of compensation and the loose tube joints and loose set limit compensation joint of different amount of compensation is that it refers to the adjustment in the process of installation and removal, once all of the nut is tightened, it is rigid connection, can pass axis force, so as to protect the valve, pump and other equipment.
Installation instructions
Double flange loose set of dowel joint used on both sides is flange connection, adjust product when installation ends with the installation of the pipe or flange length, installation and after welding, diagonally tighten gland bolts evenly, make it as a whole, and has certain displacement, convenient installation and maintenance, may be adjusted according to the size. At work can pass axial thrust to the whole pipeline.
Loose tube of dowel joint material: mainly with Q235 carbon steel, stainless steel, cast steel, ductile iron, etc. Use choose different material and different models.
Loose tube dowel joint classification are: single LanSong set of dowel joint, double flange loose set of dowel joint, detachable double flange loose set of dowel joint.
