What are the functional characteristics of corrugated metal hose

Corrugated metal hose is one of the series of metal hose products. Corrugated metal hose (referred to as hose) is a high-quality flexible pipe in the modern industrial pipeline. It has good flexibility, fatigue resistance, high pressure, good temperature resistance, corrosion resistance, strong sealing and many other characteristics, and has a much longer service life than other hoses (rubber hose, plastic hose). It is widely used in aviation, aerospace, petroleum, chemical, steel, electricity, paper, construction, rubber, textile printing and dyeing, medicine, food, transportation and other industries. With the development of modern industry, the demand for high-quality and high-performance corrugated metal hoses will be increasing.

Stainless steel metal hose is also known as corrugated metal hose and stainless steel hose. Stainless steel corrugated hose is a high-quality flexible pipe in modern industrial pipeline. It is mainly composed of stainless steel bellows, stainless steel mesh sleeve and metal hose joint.

Connectors at both ends of corrugated metal hose: connectors mainly include threaded connection, flange connection and quick connector connection.
The stainless steel mesh sleeve is the main pressure-bearing part of the metal braided hose installed on the pressure pipe, and also plays the role of protecting the metal hose. According to the pressure in the pipeline and the application site, one or more layers of stainless steel wire or steel strip can be selected to weave into high-pressure metal hose according to certain parameters. The pressure range of metal braided hose produced by our company is generally PN0.6-32.0MPa, with the maximum of 42.0MPa. Stainless steel mesh sleeve mainly includes steel mesh sleeve and steel mesh sleeve.

Corrugated hose has pressure and vacuum tightness. The allowable working pressure of small size hose reaches 380bar (the safety factor of bursting pressure is 3 times). Due to technical reasons, the pressure resistance of large size is low. The temperature resistance of stainless steel models is up to about. 600 ° C, higher values can be obtained by using special materials according to the pressure load. In the low temperature range, the stainless steel corrugated hose can be used at temperatures as low as - 270 ° C.

The main components of corrugated metal hose are made of austenitic stainless steel, which ensures the excellent temperature resistance and corrosion resistance of the metal hose. The working temperature range of metal hose is - 196-600 ℃. In the actual use process, the material of metal hose should be selected according to the corrosivity of the pipe medium to ensure the corrosion resistance of metal hose.

The three main functions of corrugated metal hose are to reduce the installation stress of the pipeline, compensate for the movement of the rated position of the pipeline, and absorb the vibration of the pipeline system.

Application of corrugated metal hose: completely flexible conveying pipe is required to prevent vibration. It can be used in steam, gas, air, heavy oil, petroleum, chemical, electric power, water conservancy and other industries.
