As we all know, the advantage of aluminum alloy composite plastic pipe fittings is to reduce the impact force, and can greatly improve the service life of aluminum alloy lined plastic pipe. The aluminum alloy plastic-lined pipe can be selected according to the wear resistance, which is suitable for the environment with high wear resistance.
Current technological progress has also promoted the development of high temperature corrosion resistance process for aluminum alloy plastic lined pipes, which has a higher temperature range and better corrosion resistance.
What can determine the quality of the centrifugal casting process of aluminum alloy plastic lined pipe? Under normal process conditions, aluminum alloy plastic lined pipe can only be converted into a straight pipe. Straight pipe should be divided into several welded sections to form elbows or small pipes. The inner wall of the elbow and the small round head structure are not aerodynamic, which makes the transportation of materials difficult and reduces the output of the equipment.
The replacement of pipe fittings is also very simple, so if you need to connect pipes, the specific installation parameters of the pipe fittings can refer to the above data. According to national standard parameters, it can be used anywhere. Therefore, the use of aluminum alloy plastic-lined pipes with grooves may require specific analysis of specific problems and should not be used arbitrarily.
When the sealing surface stops working, after removing the tool, level the sealing surface for the 1st time (with a deflated cold tire) and cool the plastic layer until the sealing surface is shiny, smooth and smooth. cured. It should be rotated when cooling to avoid local flow of high temperature, which will affect the use and appearance.
Aluminum alloy lined plastic pipe has good corrosion resistance. The rubber lining of the rubber lined pipe can be prepared according to the anti-corrosion requirements and is suitable for highly corrosive environments. The rubber lining can withstand acid, alkali, salt, organic matter, seawater, sewage, etc., and is suitable for complex and harsh chemical corrosion environment. The price development trend of the corresponding national standard stamping elbow materials for plastic-lined grooved pipe fittings: the corresponding national standard stamping elbow raw materials not only have qualified creep rupture curves, but also have their moderate price and relatively convenient construction. In the system, the fluid resistance of the system is relatively small because there are no mechanical connections and localized constriction.
