VSSJA-2(B2F) Double Flange Limited Expansion Joint

The double flange limit expansion joint is composed of main parts such as body, sealing ring, gland and extension shortening pipe.On the basis of the original performance of the loose sleeve expansion joint, a limit device was added, and the maximum expansion was locked with a double nut.The pipe can expand and contract freely in the allowed expansion and contraction quantity, once exceeds its maximum expansion and contraction quantity, plays the limit position, ensures the safe operation of the pipe, especially suitable for the connection of the pipe with vibration or certain inclination and turning.


Double flange limit expansion jointis suitable for connecting with flange on both sides. During installation,adjust the connecting length between both ends of the product and flange, tighten the gland bolt in turn and adjust the limit nut in turn. In this way, the pipe can expand and contract freely within the expansion range and lock the expansion amount to ensure the safe operation of the pipe.It is suitable for the pipe connected with flange on both sides. During installation, adjust the installation length of both ends of the product and the flange, and tighten the gland bolt evenly diagonally to make it a whole with certain displacement. It is convenient for installation and maintenance and adjust the size according to the field.Anti-axial thrust can be transmitted to the whole pipeline during operation.It can reduce the pressure thrust of the connected part (blind plate force) and compensate the installation error of the pipeline. The double flange force transfer joint cannot absorb the axial displacement.Double flange transmission is mainly used for pump, valve and other accessories loose sleeve connection.


BF(VSSJA-1) type single-flange limit expansion joint, B2F(VSSJA-2) type double-flange limit expansion joint, BY(SSJB-3) type gland limit expansion joint, AY(SSJB) type gland limit expansion joint, flange limit expansion joint, flange loose sleeve expansion joint.
