VSSJA-2 double Falan Song sets limit expansion joints

Double Falan Song sets limit expansion joints range of applications
    Double Falan Song sets limit expansion joints suitable for conveying water, fresh water, hot and cold water, drinking water, sewage, crude oil, fuel oil, lubricating oil, refined oil, air, gas, temperature not higher than 250 degrees of steam and grain powder and other media.
Double Falan Song sets limit expansion joints Features
    Double Falan Song the set limit expansion joints Model VSSJA a 2 or the B2F type, on both sides of the pipe flange connection, installed in the pipe and the valve can be connected to both compensate for the amount of stretching of the pipe and the valve repair provides convenience.
    Double Falan Song sets limit expansion joints loose telescopic joint and a flange limit short-tube combination. Double Falan Song sets limit expansion joints to prevent pipe joints for leaks and damage compensation caused due to excessive displacement, mainly for the pipe to allow absorption in the range of displacements axial displacement and to withstand axial pressure thrust loose tube connection.
Double Falan Song sets limit expansion joints advantages: telescopic volume, convenient installation.

Double Falan Song sets limit expansion joints Features: For pipes connected at both ends of the flange above.
Double Falan Song sets limit expansion joints installed a brief description:
    B2F double Falan Song sets limit expansion joints applies to both sides of the flange connection ends with flange connection length, installation, adjustment, tighten the gland bolts evenly angle turn, and then adjust the limit nut so that can make the pipeline can be free to expand the range of the amount of stretching, lock the amount of stretching to ensure the safe operation of the pipeline.
