How to purchase PVC steel wire hose with good quality?


Observe whether the lumen is regular and the wall thickness is uniform? The PVC STEEL WIRE HOSE with good quality and inner rim and outer margin are standard circular, and the circular tube wall is evenly distributed. Taking PVC STEEL WIRE HOSE with 89 mm inner diameter and 7 mm wall thickness as an example, the thickest part of the pipe wall with poor quality can reach 7.5mm and the thinnest part is only 5.5mm. When working under high pressure, it is easy for the uneven stress on the pipe wall to cause the bursting or deformation of PVC STEEL WIRE HOSE, which will affect the normal use.

2. Observe whether there are bubbles or other visible substances on the wall of PVC STEEL WIRE HOSE, and whether they are colorless and transparent. The high quality PVC STEEL WIRE HOSE wall is crystal clear without any impurities. The yellowing color of inferior PVC STEEL WIRE HOSE may be caused by improper decomposition, aging or long-term improper storage in the production process.
3. High-quality PVC STEEL WIRE HOSE has no odor of any petrochemical products except a little plastic odor. The inferior steel hose has a nasty smell of diesel oil, especially in hot summer, people can not get close to it.
4. The inner and outer walls of high-quality PVC STEEL WIRE HOSE are smooth and feel good, while the low-quality tubes are rough.
5. When measuring wall thickness, the two ends of PVC STEEL WIRE HOSE should be cut off and the intermediate tube should be selected as the sample for testing.
