1. When use PCV line hose in small diameter, it should past with solvent to improve the stability and hardness. Otherwise, it is easy to use the process. Then cause leakage and reduce its normal use function. Then reduce work efficiency.
2. To install a large diameter PCV hose (diameter ≥ 100mm), you should use a rubber ring to interface first. Then arrange personnel to cut the sleeve part. This time, keep the cut clean, otherwise it will bring trouble to the builder during install.
3. When install the PCV steel wire hose, if there is no special demand, directly put it into the trench dug in advance. Then seal it. Of course, in order to improve the service life, many people will add compaction cushion.
4. PCV steel hoses are not suitable for use in high temp. Because harmful gases easily release to the human body. Then causes pollution, and may also lead to changes in liquid transfer. Therefore, when use PCV steel wire hose, you have to focus on the install condition.
PVC steel wire hose specs:
Inner diameter 10-250mm
wall thickness 2-14mm
Features: it is a PCV hose with steel wire skeleton. The inner and outer tube walls are transparent, smooth, and free of air bubbles. Thus the fluid is clearly visible. it is resistant to low acid and alkali. Besides, it has high elasticity and it is not easy to age. Thus it has a long service life. What’s more, it can bear high pressure and maintain its original shape under high pressure and vacuum. Temp: -5℃~65℃
working pressure: 0.5MPa, burst pressure: 1.2MPa
Specifications: GB/T10546-2003 LPG uses PCV steel wire hose and assembly. It is also suitable for bulk product transfer.
Develop situation: GB10546-1989 LPG PCV steel wire pipe, which stipulates that railway transport tank cars and roads use tank cars. Also pipelines to transport China liquefied petroleum gas (LPG) in bulk with a pressure of 2MPa.
