Nowadays, with the continuous development of society Sandblasting pipe It is widely used in all walks of life and has become a common product in social industrial products. After purchasing the steel wire sandblasting pipe, its safety is very important to the user, which is related to safety. So, how to test Steel wire sandblasting pipe What about security? Today, the manufacturer of steel wire sandblasting pipe will give you a specific introduction.

1. Pressure test: carry out pressure test on steel wire sandblasting pipe to check whether the pressure of rubber pipe is qualified, whether the pipe body has leakage, and whether the parts are damaged, so as to judge whether the safety of rubber pipe is good.

2. Air tightness test: air tightness test shall be carried out for steel wire sandblasting pipe. As required, drilling and clean air or nitrogen or other maintenance gases shall be used as the test medium to test for air leakage in the hose.

3. Whether the quality of rubber hose is consistent: check whether the quality of rubber hose is consistent and whether there are irregular phenomena such as colloid adhesion. If there is any violation, it will be regarded as unqualified.

4. Soft tolerance test: moderately twist the steel wire sandblasting pipe to see if it has a certain tolerance, so as to avoid abnormal cracking due to twisting and torsion during use, thus affecting the normal use of users.

Polyurethane steel wire tube reinforced hose, steel wire elastic hose and spiral steel wire reinforced hose are all made of polyurethane TPU material. TPU is the most wear-resistant of all plastic materials, which can absorb dust, powder, fiber, debris and particles, gas and liquid environments, and is used for dust removal and suction plants, industrial vacuum cleaners, paper and textile fibers. It is made of special TPU embedded spiral steel wire, and has the functions of wear resistance (3-4 times better than rubber, 6-7 times better than soft PVC), aging resistance, tear resistance, high brightness, light weight, good elasticity, outstanding elasticity, low temperature compression, etc., Ultra high strength, long service life.

Temperature scale: about - 40 ℃ to 125 ℃, about 150 ℃ in a short time.

Various wall thicknesses: 0.4 mm, 0.6 mm, 0.9 mm (the thinnest part, excluding steel wire)

First, let's look at the relationship between the wall thickness and various application functions of polyurethane steel wire elastic pipes.

1. The thinner the wall thickness, the better the flexible bending performance of polyurethane steel pipe. The 0.4mm polyurethane steel pipe has great elasticity, high elastic frequency in the same time, and is the easiest to wind together. This thick wall spiral steel pipe is suitable for mechanical ventilation and dust removal with high requirements for pipe elasticity and winding function.

two Steel hose The thicker the wall thickness, the better the wear resistance and corrosion resistance. 0.9mm polyurethane pipe has high abrasion resistance due to its thickest wall thickness. Under the same wear condition, the service time is the longest. Together, it has good acid and alkali resistance and corrosion resistance. The invention is applicable to the working environment with high abrasion and high pH value.

3. The wall thickness of polyurethane steel pipe with 0.6mm wall thickness is between 0.4mm and 0.9mm, and its elasticity, abrasion resistance and corrosion resistance are also between the two, which is the most commonly used.
