With the development of modern industry, there is an increasing demand for high temperature and high pressure resistant corrugated metal hoses. The stainless steel metal hose is the main pressure-bearing part of the hose installed in the pressure pipeline, and it also acts as a sheath for the bellows.
The scope of application of the hose: a fully flexible conveying pipe is required to prevent vibration in the piping. It is suitable for steam, gas, air, heavy oil, petroleum, chemical drugs, etc.
It is an important connecting component in engineering technology, which is composed of corrugated flexible pipes, net sleeves and joints. In various gas and liquid pipeline systems and length, temperature, position and angle compensation systems, as compensation components, sealing components, connection components and shock absorption components, metal hoses are used in aerospace, petrochemical, mining electronics, machinery Shipbuilding, medical and health, textile and electronics, energy construction and other fields.
From the layout point of view, there are two types of metal corrugated pipes: strips and pipes, both of which can be formed into annular corrugated pipes and spiral corrugated pipes.
The ring-shaped corrugated pipe is a pipe with a special geometric shape in which the outer edges of a plurality of circular diaphragms are tangentially connected with a plurality of semicircular rings of the concave surface, and the inner edge is tangentially connected with the semicircular rings of a plurality of concave vests. The blanks are mainly pipes. This type of corrugated pipe has the characteristics: great flexibility, good elasticity, simple production, and low rigidity. It is suitable for making large and medium diameter metal hoses that accept normal working pressure and require higher flexibility.
The spiral corrugated tube is a spring-shaped diaphragm with a certain length. The outer edge of the spring-shaped diaphragm is tangent to the semi-circular ring of the spring-shaped concave surface, and the inner edge is tangent to the semi-circular ring of the spring-shaped concave vest. A pipe in the shape of a dash. This type of corrugated pipe has the characteristics of high strength, high rigidity, and simple production. It is more suitable for making high and medium pressure, medium and small diameter metal hoses with ordinary flexibility and higher strength requirements.
