How to identify the quality of PVC garden hose?
PVC Garden Hose Wall Thickness: It depends on whether the wall thickness is specified. Here we should also pay attention to some empty tubes. The walls at both ends should meet the requirements, but the wall thickness in the middle is very thin, can not meet the requirements, and the cost is very high.
PVC Garden Hose Length: See if the length is needed. Some manufacturers reduce prices by shortening the length. According to GB/T10002.1-2006, no negative deviation is allowed.
Second, look at the surface of the PVC garden hose
1. Look at the gloss: The surface is good, the oil is good, is a high-quality product.
2. Look at the color: The standard high-quality PVC-U pipes are light brown. If excessive calcium powder is added to the pipes, impurities and recycled materials from some manufacturers are added too much to make the pipes black and yellow.
Three.
Weight: Take the weight of the same caliber, wall thickness, length of two tubes, high weight calcium powder, impurities and add too many material impurities, which do not meet the requirements.
