1. Compared with metal pipes, PP-R pipes have lower hardness and lower rigidity. They should be protected during transportation and construction to avoid mechanical damage caused by inappropriate external forces. Mark the location of the pipeline after the dark application, so as not to damage the p...
1. PPR pipes and fittings are connected by hot melt, but they cannot be threaded directly on the pipes and fittings. When connecting with metal pipes, flange connections can be used. When connecting with water heaters, pipe fittings with metal inserts must be used. ;2. In the process of hot-melt con...
Advantage1. Small flow resistance. The medium channel inside the valve body is straight, the medium flows in a straight line, and the flow resistance is small.2. Less effort when opening and closing. It is compared with the stop valve, because whether it is open or closed, the direction of movement ...
(1) It is necessary to find out that the upstream and downstream pipelines of the ball valve have indeed relieved the pressure before disassembling and disassembling.(2) Non-metal parts should be taken out of the cleaning agent immediately after cleaning, and should not be soaked for a long time.(3)...
Having a long service life and maintenance-free period will depend on the following factors: normal working conditions, maintaining a harmonious temperature/pressure ratio, and reasonable corrosion dataWhen the ball valve is closed, there is still pressurized fluid inside the valve bodyBefore mainte...
1. Wear-resistant; because the spool of the hard-sealed ball valve is spray-welded with alloy steel,The sealing ring is made of alloy steel surfacing, so the hard-sealed ball valve will not produce too much wear when it is switched on and off. (Its hardness coefficient is 65-70) 2.the sealing perfor...
