HDPE pipe and UPVC pipe differ in their base manufacturing material; their full pipe rigidity, modulus of flexibility; their fabricated storage lengths and diameter sizes; their plumbing system joining methods; their compatibility resistance to chemi...
First off, I have no dog in the fight and use PEX, CPVC and PVC according to what is most suitable for the application. I would like to correct and expand upon some of the statements made in a previous reply. PEX is cross-linked polyethylene for use ...
1. The plasticization of PVC pipes and fittings must be high, and the plasticization should be as high as possible. As long as the decomposition does not change color, the plasticization can be properly improved, making the relative high point of the...
PVC which means no plasticiser (US: plasticizer) has been added to the PVC compound. Unplasticised PVC is also known as rigid PVC. PVC-U is the most common PVC type for pipes and fittings including transportation of drinking water, soil and waste, se...

1. Why should the outlet valve be closed when the centrifugal pump is started? When the centrifugal pump is started, there is no water in the outlet pipe of the pump, so there is no pipeline resistance and lifting height resistance. After the centrif...
The use pressure of new pipes, especially plastic pipes, is related to many factors, such as pipe diameter, pipe wall thickness, service temperature, pipe fitting processing method, pipe fitting and pipe connection method, etc. Among them, the connec...
(1) Direction and position Many valves are directional, such as shut-off valves, throttle valves, pressure-reducing valves, check valves, etc., if installed backwards, it will affect the use effect and life (such as throttle valve), or will not work...
