Introduction to BY (SSJB-3) type gland type loose sleeve limit expansion joint

BY (SSJB-3) type gland type loose sleeve limit expansion joint, with reasonable product structure design and reliable sealing performance; Both ends adopt socket connection, which is convenient for installation and disassembly. The BY (SSJB-3) type gland type loose sleeve limit expansion joint is suitable for connecting steel pipes, cast iron pipes, ductile iron pipes, PAC pipes, ABS pipes, etc. that transport water, oil, gas, and particulate matter. When connected, it can compensate for the axial displacement of the pipe and a certain amount of deflection and eccentricity.

The BY (SSJB-3) type gland type loose sleeve limit expansion joint is based on the original loose sleeve expansion joint by adding a limit device, which is locked with double nuts at large expansion amounts. This allows the pipeline to expand freely within the allowable expansion amount. Once the larger expansion amount is exceeded, the limit is set, which effectively ensures the operation of the pipeline, It is particularly suitable for connection in pipes with vibration or a certain inclination and in bends.

Use of BY (SSJB-3) type gland type loose sleeve limit expansion joint

The gland type loose sleeve limit expansion joint has good comprehensive performance, so it is widely used in basic engineering such as chemical engineering, construction, water supply, drainage, petroleum, light and heavy industry, refrigeration, sanitation, plumbing, fire protection, electric power, etc.

Both sides of the gland limit expansion joint are welded to the pipe. During installation, loosen the gland nut, adjust to the installation length, and then weld the short pipe at both ends to the pipe. After that, tighten the nut evenly using the diagonal method, and adjust the anti release nut.
