It is a kind of pipeline joint with high elasticity, high airtightness, media resistance and weather resistance.···

The expansion joint can avoid the leakage or destruction of the compensation joint caused by the excessive offset of the pipeline, and is mainly used for the loose joint of the pipeline that absorbs the radial offset and withstands the force pushing force···

Low temperature method: Take a small sample of rubber joint from the finished product and create a suitable low temperature environment with dry ice and alcohol. Soak the rubber joint sample in the low-temperature environment for 2-5 minutes and feel the···

In daily life, will often see the pipeline connected to the place will have a similar joint things will be connected to the two, this is the double flange limit expansion joint, and many users in the use of a period of time, found that the double flange l···

Through the wall casing specifications focus on the fact that before starting work, staff need to be familiar with the drawing information carefully, carefully comprehend the drawing requirements, and comply with the construction specifications for constr···

The difference of double flange limit expansion joint is that its compensation amount refers to the adjustment amount during installation and disassembly. Double flange expansion joint is suitable for transporting seawater, fresh water, hot and cold water···

Clamp type rubber duckbill valve over solid materials, but there are certain installation restrictions. General over the liquid, water flows down, water as long as it is large enough to open the duckbill valve, so that it works properly, but if it is a so···

Threaded rubber joint is composed of a rubber sphere and two metal parallel movable joints. This kind of threaded soft joint is mainly used for steel pipe, copper pipe and high pressure connection, the thread of welded steel pipe is currently mostly opera···

1. Check the outer surface of the duckbill valve installation pipeline or connecting flange for burrs, deformation, smooth and flat.
2. The installation of the socket type duckbill valve should make the inner diameter of the duckbill valve and the outer···

The opening degree of rigid waterproof casing main pipe is determined by the size of the water impact in the pipeline, the main pipe opening degree is large when the flow rate is high: the pipe opening degree is small when the flow rate decreases: when th···

Product role
