Joints at both ends of the metal hose: the joint mainly includes threaded connection, flange connection, and quick joint connection. The three major functions of the metal hose: 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.Construction metal
The stainless steel mesh sleeve is the main pressure-bearing part of the metal braided hose installed in the pressure pipe, and at the same time protects the metal hose. According to the pressure in the pipe and the application place, one or more layers of stainless steel wire or steel can be selected The belt is made by weaving according to certain parameters to form a high-pressure metal hose. The pressure range of the metal braided hose produced by our company is generally PN0.6-32.0MPa, up to 42.0MPa. There are two types of stainless steel mesh sleeves: steel mesh sleeves and steel mesh sleeves.
Characteristics of corrugated metal hose:
1. The maximum allowable expansion per wave is recommended: full-height △ α = ± 24mm, half-height △ α = ± 12mm.
2. Ash baffle: It can be omitted for air ducts or ducts with less dust. Ash baffle should be used for dusty flue.
3. In order to reduce the number of nodes of the bellows, cold drawing should be considered by 50%.
4. The standard half-height corrugated metal hose is suitable for occasions where the cross-sectional area is less than 4.6 square meters and the outside dimension of the flue duct is less than 1.5m but greater than 0.6mm. Standard full-height corrugated metal hose is suitable for all flue ducts.
Corrugated metal hose has many characteristics such as good flexibility, fatigue resistance, high pressure resistance, high and low temperature resistance, corrosion resistance, etc. It has a much longer life than other hoses (rubber, plastic hose), so It has high comprehensive economic benefits. With the development of modern industry, your demand for high temperature resistant and high pressure resistant corrugated hoses is increasing.
Scope of application of hoses: need to be fully flexible delivery pipe, to prevent vibration piping, suitable for steam, gas, air, heavy oil, petroleum, chemical drugs, etc.
