PVC clear hose pipe is flexible with light weight, the hose tube is fully transparent with various colors. But sometimes it can be found that there are bulges on hose surface, which will affect the overall appearance of the hose. Then, why does the PVC clear hose pipe have bulge?
1. Plastic mesh bags are too loose
In the case of PVC clear hose pipe, the horizontal load in the inner and lower working pressure triggered by the material is borne by the hose, and the vertical load is accepted by the plastic net bag covered with the PVC clear hose. Because the plastic mesh bag is woven by equipment, when the plastic mesh bag is woven by hand too loose, avoid the side pressure with the vertical load of strong vibration, it will lead to the plastic mesh bag lifting scene often occurs.
2. The hand weaving angle is too large
If the net in the whole process of manual weaving angle of PVC clear hose pipe is too large, it will lead to the penetration rate of plastic mesh bag, plastic mesh bag is loose, plastic mesh bag and PVC clear hose pipe to meet the density, when hose deformation is easy to bulge.
3. The bending radius is too small
In the actual loading process, it is because the PVC clear hose pipe is limited in mid-air, the length of the PVC clear hose pipe selected is not matched with the set overhead specifications, such as the nominal size of DN150, the stiffness section distance of the sample is 100 mm, the vertical offset is 250Mm, and the small bending radius is 1800mm, Its reasonable measurement verification small sample length is 7525 mm, but in fact the length is 10000mm, due to the relatively limited indoor space, will lead to PVC clear hose pipe some span bending, with the surface pressure prefabricated components plastic mesh bag deformation, and then appear bulge.
