    Technology empowers to create high-quality products. Innovation Steel expansion Key points of product knowledge:：The double flange limit expansion joint is composed of body, sealing ring, gland, extension and shortening pipe and other main components. On the basis of the original performance of the loose sleeve expansion joint, a limiting device is added, and double nuts are locked at the maximum expansion capacity. vssja-2(b2f) double flanged limit expansion joint is suitable for connecting both sides with flanges, adjusting the connection length of both ends of the product during installation, tightening the gland bolt evenly in turn, and then adjusting the limit nut, so that the pipe can expand freely, lock the expansion amount, and ensure the safe operation of the pipe.
