Difference between rigid and flexible waterproof casing
Rigid waterproof casing is steel pipe plus wing ring (steel plate made of ring set on the steel pipe), installed in the wall (mostly concrete walls), for general piping through the wall, to facilitate the waterproofing of the wall; flexible waterproof cas

What are the reasons for cracking of rubber joints explained by luoying?
The rubber joint may also crack if the connection length is insufficient during use, forced to exceed the connection length, and the contraction range is expanded at will.

Will the non-metallic compensator be different from the design during construction?
Non-metallic compensator in this case mainly relies on the design unit to control the construction of the heat network layout integrity. In the case of large changes in the pipeline, special attention should be paid to the form of force of the pipeline is

How much do you know about the maintenance of single sphere rubber soft joint?
When using or storing rubber joints, avoid high temperature, ozone oil and acid-alkali environment. The pipeline used outdoors or facing the sun and the wind should be built with a shade frame, and the sun screen, rain and wind are strictly prohibited. Pa

Description of expansion joint performance and parameters
Expansion joints have saturated nonlinear characteristics (e.g., temperature piping). When the flow rate is small, the pipeline can operate normally, but when the flow rate is large, the pipeline is sluggish. Or the pipeline is sensitive or even oscillati
