Stainless steel metal hose (hose for short) is a high-quality flexible pipe in modern industrial pipelines. It is mainly composed of bellows, mesh sleeves and joints. Its inner tube is a thin-walled stainless steel corrugated tube with a spiral or annular shape. The mesh sleeve of the outer layer of the bellows is made of stainless steel wire or steel strip woven according to certain parameters. The fittings or flanges at both ends of the hose are matched to the fittings or flanges of the customer's pipeline.
The corrugated pipe of the metal hose is formed by a very thin-walled seamless or welded stainless steel pipe through high-precision plastic processing. Due to the elastic characteristics of the contour of the bellows, the softness and fatigue resistance of the hose make it easy to absorb cyclic loads of various motion deformations, especially in the pipeline system, which has the ability to compensate for large displacements. It play an important role in displacement compensation, thermal expansion absorption, and vibration absorption . The characteristics of this metal hose are corrosion resistance, high temperature, low temperature resistance, light weight, small size, good flexibility and excellent shock absorption. Corrugated metal hose has many characteristics such as good flexibility, fatigue resistance, high temperature resistance, high and low temperature resistance, corrosion resistance, etc. Compared with other hoses (rubber and plastic hoses), its lifespan is much higher, so It also has higher comprehensive economic benefits. With the development of modern industry, the demand for corrugated metal hoses resistant to high temperature and high pressure is increasing.
Use scope of the hose: Delivery pipe which need have a fully flexibleness, and piping at the place to prevent vibration. It is suitable for steam, gas, air, heavy oil, petroleum, and chemicals. Five elements for the manufacture of metal hoses: 1. Size: the nominal diameter of the hose, the type and size of the joint, and the length of the hose. 2. Pressure: the actual working pressure of the hose, the selected nominal pressure /working pressure. 3. Medium: The chemical properties of the medium conveyed in the hose, according to the corrosion resistance table, determine the material of each part of the hose. 4. Temperature: The working temperature and range of the medium in the hose; the ambient temperature when the hose is working. When the temperature is high, the maximum pressure allowed under the working temperature must be determined according to the temperature correction coefficient to determine the correct pressure level. 5. Status: According to the status of the hose when it is used, refer to the correct installation method of the hose, according to the calculation of the length of the hose in various motion states and the minimum bending radius of the hose, the length of the hose is correctly selected and installed correctly. Over the past few years, our Qinhuangdao FECT Industry Co., Ltd. has continuously developed new products, improved product quality, and done a lot of research and experimental work. If you need products with special specifications, they can be designed and manufactured according to user requirements.
