Two common types of steel wire hoses: PVC steel wire hoses, PU steel wire hoses
Steel wire hose is a kind of industrial hose produced from plastic steel wire with elastic steel wire. There are many types of steel wire hose, such as PVC rigid wire hose, PU steel wire hose and other common second-class steel wire hoses.
The first category: PVC steel wire hose is a kind of high-quality environmentally friendly PVC synthetic material embedded with hard plastic steel wire spiral skeleton, smooth inner and outer walls, small bending radius, and has good negative pressure resistance. The material is rich in anti-aging, anti-ultraviolet radiation raw materials, and has high anti-aging performance. The PVC steel wire hose is lighter in weight, the tube is transparent, and has excellent weather resistance and high negative pressure resistance. The inner surface is smooth and the outer surface has wrinkles. The external thread form of the ribs reduces the wear rate of the pipe body in contact with the ground and other environments. It is very light and elastic, with high air pressure resistance and resistance to most chemicals. The pipe wall is made of flame-retardant PVC material, with spiral steel wire coated with plastic reinforcement. PVC steel wire hose is suitable for industry, agriculture and water conservancy, air conditioning and ventilation systems. It can transport gas, welding fumes, dust (moderate abrasion resistance), and vacuum suction powder, particles, water, oil, etc. in civil engineering.
The second category: PU steel wire hose used for conveying industrial wear-resistant dust-absorbing granular materials. It is an industrial vacuum hose produced by German imported polyurethane pu material with copper-plated steel wire. It is mainly used For industrial vacuuming, such pu steel wire hoses are used in industrial vacuum cleaner hoses, ceramic machinery cutting, particle material transportation, woodworking vacuum pipes, and drilling machine vacuum pipes. The wall thickness range is about .4mm, 0.6mm, 0.9mm and other commonly used specifications, and of course there are 1.2mm, 1.5mm thicker specifications.
Polyurethane steel wire hose has high abrasion resistance (abrasion resistance is 2.5 to 5 times that of most rubber materials, 3 to 4 times that of most soft PVC materials), stretchable, high tensile strength and tearing Strength; good mineral oil resistance, good chemical resistance, good UV and ozone resistance, good low temperature flexibility, small bending radius, not easy to kink, no softener, plasticizer and halogen, transport Gas and liquid do not leak. Comply with ROHS regulations, grounding spiral steel wire can discharge static electricity (according to BGR-132, formerly ZH 1/200). The pu steel wire hose is often used for the transfer and suction of particles, scraps and abrasive powder. It is especially suitable for powder conveying and dust suction in woodworking and ceramic industries.
