For example, EMT pipe bender manufacturers and other manufacturers producing and manufacturing pipes, drainage pipes are absolutely indispensable, because drainage pipes are widely used in pipes. But many people are confused when they choose drainage pipes, because they don't know what kind of drainage pipe is the best,
EMT pipe bender manufacturers tell us that in fact, it is not so difficult to select drainage pipes, mainly based on these four points. 1. The pipe should be rigid enough, especially the drainage pipe. When pressing the pipe by hand, there should be no deformation. Through this point, you can press the pipe by hand when you choose to see whether the pipe will deform and how hard it is. 2. Consumers should pay attention to observe whether the pipes are marked with national standards when purchasing pipes. If the pipes are enterprise standards, attention should be paid. Because the national standard drainage pipe has a better reputation, and the quality is also guaranteed.
3. EMT pipe bender manufacturers remind users that they should also pay attention to the pressure grade of drainage materials, and pay attention to select the pressure grade that meets the actual use requirements. Generally speaking, the hot water pipe should be selected with pipe series s less than 2.5, that is, the wall thickness of pipe with outer diameter of 20 should be more than 3.4mm, and that of pipe with outer diameter of 25 should be more than 4.2mm. Finally, we must pay attention to the appearance of the pipe, the pipe should be smooth, flat, no bubbles, discoloration and other defects, uniform color, no impurities, uniform wall thickness.
