1. High-quality pvc steel wire reinforced pipe wall inside and outside are smooth and feel good and low-quality pipe is more rough.
2. Observe whether the rules of the lumen, wall thickness is uniform. The quality of pvc wire reinforced tube lumen and the outer edge of a standard circular annular wall distribution. The diameter of 89mm wall thickness 7mm pvc steel wire reinforced tube, for example, the poor quality of the thickest wall can be 7.5mm thinnest at only 5.5mm at high pressure is easy to work under uneven pressure led to pvc wire reinforcement Tube rupture or deformation affect normal use.
3. Measurement of wall thickness should be truncated pvc wire reinforced both ends of the tube Select the middle of the tube as a sample test to prevent part of the unscrupulous manufacturers in the tube to make an article on both ends of the actual thickness thinner than both ends of the tube.

6. Observe pvc steel wire tube wall to enhance the existence of bubbles or other visible material is colorless and transparent. High-quality pvc steel wire reinforced tube wall crystal clear without any impurities. The defective pvc steel wire yellowing may be due to improper handling in the production process has been decomposed, aging or improper storage for a long time.
