B2F(VSSJA-2) Double flange Limit expansion joint
B2F(VSSJA-2) Double flange Limit expansion joint
The double flange limit expansion joint is composed of body, seal ring, gland, extension and shorten pipe and other main components.
DETAILS

The double flange limit expansion joint is composed of body, seal ring, gland, extension and shorten pipe and other main components.On the basis of the original performance of the sleeve expansion joint, a limit device is added to lock the expansion joint with double nuts.Pipeline in the scale of allowing free expansion, once more than the expansion amount limit, ensure the safety of pipeline operation, especially suitable for the vibration or have a certain slope and curve of pipeline connection.

The installation

Double flange limit expansion joint is suitable for both sides with the flange connection, when installation, adjust the product at both ends and the connection of the flange length, diagonal in turn evenly tighten gland bolts, adjust limit nut again, so you can let the pipeline within the scope of scale free expansion, locking, the expansion amount to ensure the safe operation of pipeline.Applies to both sides and pipe flange connection, adjust product when installation ends with the installation of flange length, diagonal fund-raising even tighten gland bolts, make it become as a whole, and has certain displacement, convenient installation and maintenance, adjustments according to the size.When working, the reverse axial thrust can be transmitted to the whole pipeline.It can reduce the pressure and thrust (blind plate force) of the connected parts and compensate the installation error of the pipeline.Double flange force transfer connection is mainly used for loose sleeve connection of pump, valve and other accessories.

The material

Double flange limit expansion joint material: Q235 carbon steel, stainless steel, cast steel, ductile iron, etc.
