Functional characteristics of spiral wound corrugated hose

Spiral wound corrugated pipe is composed of metal inner and outer layers and high temperature resistant plastic outer protective layer,

Spiral wound corrugated pipe is composed of metal inner and outer layers and high temperature resistant plastic outer protective layer, and the outer wall of the pipe is formed into a network pattern through multi-layer spiral winding. At present, the spiral wound hose produced in my country has a metal inner sheath outside, which can withstand relatively high pressure, but it is not resistant to high temperature (the maximum working temperature is 270°C).

Due to the low level of manufacturing and production technology in our country, especially when the pipeline transports high-temperature media, the outer layer of high-temperature-resistant plastic loses its original performance due to excessive temperature. The inner and outer layers of the steel wire wound hose are made of high-temperature-resistant plastic, which has stable chemical properties, is not easy to age and deteriorate, and has a long service life. It consists of three parts: outer sheath, inner sheath and hose core. The outer layer is made of anti-oxidation and heat-resistant metal material; the inner layer is made of heat-resistant plastic.

Steel wire wound hose has many unique advantages over ordinary rubber or fiberglass pipes:

1. Corrosion resistance: not affected by medium (including acid, alkali and oil);
2. High impact resistance: high strength, impact resistance;
3. Heat resistance and heat resistance: the highest temperature resistance can reach 260°C;
4. High internal pressure strength, the hose core is a circular cross-section, and there is no internal leakage. Allow to withstand greater pressure;

Functions and Features

1. Spiral wound hose is resistant to high temperature (up to 400°C), high pressure resistance, good insulation performance, safe and reliable, and long service life;
2. The spiral wound hose is suitable for conveying various media (oil, water) and solid powder media. The temperature range of the conveying medium is wide (-50°C~+200°C), effectively ensuring the reliability and economy of pipeline operation;
3. The spiral wound hose has good chemical corrosion resistance and can be used to transport corrosive media;
4. The structure of the spiral wound hose is simple, and the connection is convenient and quick;
5. The spiral wound hose has excellent tensile properties;
6. The inner wall of the pipeline is smooth and the frictional resistance is small, which can reduce energy loss and improve transmission efficiency when transporting fluid.
