How much do you know about PVC hoses?

Jul. 13, 2021

As we all know, there are various types of plastic hose, such as steel wire tube, wire tube, hose, snake skin tube, fiber tube, high pressure tube, composite tube, rubber plastic tube, plastic rib tube and so on. So today, we mainly talk about PVC steel wire reinforced hose and PVC plastic rib spiral reinforced hose.

1. PVC steel wire reinforced hose

PVC steel wire reinforced hose is also commonly known as transparent steel wire pipe, but in the PVC hose industry, it is referred to as "steel pipe" for short. The product is made of PVC resin as the main raw material, embedded with high-strength steel wire frame, so it is both rigid and flexible. It not only has sufficient mechanical properties and rigidity, but also has excellent flexibility.

Under normal circumstances, according to the performance of the hose, we can divide it into ordinary PVC steel wire spiral reinforced hose, PVC steel wire high-strength polyester fiber composite reinforced hose, PVC high temperature/low temperature resistant steel wire spiral reinforced hose, and PVC anti-corrosion hose. Electrostatic steel wire spiral reinforced hose and so on. Or according to the purpose, it can be divided into industrial grade (specially transporting industrial water, oil, sewage, powder, chemical raw materials, etc) and food grade (food factory transporting fruit juice, milk juice, edible water, winery transporting liquor, beer, etc) . This hose is widely used in industry and agriculture; it is an ideal pipe for conveying liquid, gas, powder and particles.

2. PVC plastic rib spiral reinforced hose

  The main characteristics of PVC plastic rib spiral reinforced hose are smooth inner wall, soft texture, good elasticity, UV resistance, corrosion resistance, weak acid and alkali resistance, and good weather resistance. It is suitable for vacuum suction of powder, particles, water and oil in industry, agriculture, water conservancy and civil engineering. It is an excellent substitute for rubber tube and metal tube.

In recent years, with the increasing demand for steel wire pipes, many manufacturers of steel wire pipes have been born. The PVC transparent steel wire pipes produced are even more diverse and vary in quality. Therefore, we have summarized several methods for judging the quality of steel wire pipes below, hoping to help you choose better quality hoses:

Observe the tube wall

Observe whether the wall thickness of the steel wire tube is uniform. If the manufacturer allows it, it will be more direct to sample from the middle. The main purpose is to prevent criminals from making fraud in the production process. The uneven thickness of the tube wall will cause easy breakage and explosion during use. Severely shorten the service life of steel wire pipes.

Is it transparent

Good-quality steel pipes should be transparent, odorless, crystal clear, and free of any impurities; on the contrary, low-quality PVC hose particles doped with impurities will cause yellowing, opaque and opaque pipe walls, and no anti-aging phenomena.

Does it have a pungent smell

The high-quality steel pipe has a very small odor. Except for the faint plastic smell, there is no pungent odor like petroleum additives. On the contrary, the low-quality steel pipe has a pungent smell and is made of a large amount of recycled materials and chemical raw materials. Especially in the high temperature season, it is impossible to get close at all, and the smell is very big.

Is it fragile

Take a section of steel wire from the cut surface of the steel wire tube to do an experiment to see if it is easy to break. A good quality steel wire needs professional tools to cut. In addition to ensuring its flexibility, a good quality steel wire tube needs to increase its tensile strength.

The above are some simple methods for judging the quality of transparent steel wire hose, for reference only. If you want to know more about plastic hoses or other rubber hoses, please pay attention to us!
