Double flange limit retractor

Introduction to Double Flange Limit Telescopic Device

Double flange limit expansion joint is also known as double flange loose sleeve limit expansion joint. The model of this product is VSSJA-2 or B2F, which is a new type of pipe compensation joint.

Double flange limit expansion device is suitable for connecting both sides with flanges. Its function is to allow free expansion within the expansion amount. Once the expansion amount is reached, it can play a limit role. During installation, adjust the connection length between both ends of the product and the flange, tighten the gland bolts diagonally and uniformly, and then adjust the limit nuts. This allows the pipeline to expand freely within the expansion amount, lock the expansion amount, and ensure the smooth operation of the pipeline.
