In most cases, without any testing tools and testing conditions, we can roughly identify the quality of the PVC hose according to the sense of sight, smell and touch.

1.Observe whether the rules of the lumen, wall thickness is uniform. Good quality PVC steel hose cavity and the outer edge of the standard circular annular wall distribution.

2.Observe whether there is bubble or other naked eye visible hose wall is colorless and transparent. High-quality PVC hose wall is crystal clear with no impurities. The defective PVC hose color yellowing may be due to improper handling in the production process has been decomposed, aging or improper storage for a long time.

 

3.High quality PVC hose except a little plastic smell without any other petrochemical odor. Poor steel wire hoses have a pungent smell of diesel, especially in the hot summer is even more inaccessible.

 

4.High-quality PVC hose inside and outside the wall are smooth and feel good and low quality of the hose is more rough.

 

5.The measurement of wall thickness should be truncated PVC hose ends of the selected part of the middle hose as a sample test to prevent some unscrupulous manufacturers to do two articles in the hose wall thickness is thinner than the ends of the hose.

 

6.At both ends of the PVC wire hose interception of a few centimeters of wire repeatedly folded wire test wire strength and toughness. Poor quality wire folding one or two will be broken and high quality PVC steel wire need special tools to cut off. The quality of the wire determines the quality of the entire hose due to the quality problems caused by the wire PVC hose is prone to irreversible deformation.
