14 years of experience in the corrugated metal hose industry.
A corrugated metal hose is a vital connection fitting between pipelines or equipment. People have created many kinds of metal hoses with different connection ends to meet various connection needs. In some applications with high temperature, low temperature, high pressure or corrosive flow medium, the corrugated metal hose is a better choice to replace the rubber hose.
The corrugated metal hose can be bent freely within the rated bending radius, which brings great flexibility and convenience to pipeline installation.
The corrugated metal hose can compensate for the pipeline’s displacement due to thermal expansion and contraction or vibration.
The corrugated metal hose can also absorb the vibration generated by the operation of the pipeline or equipment and can also reduce the noise.
Corrugated metal hoses consist of bellows hoses, braids, and a wide variety of connection fittings. The corrugated metal hose acts as a flexible connection and is the core component of the pipeline connection. The braid is used to protect the bellows hose and to improve the pressure resistance. According to different applications, choose the corresponding connection fittings.
The corrugated hose is the core functional body of the corrugated metal hose, which plays the role of a flexible connection.
According to the most significant difference in appearance, it can be divided into the annular corrugated hose and the helical corrugated hose.
The stainless steel braid is the central anti-pressure part of the corrugated metal hose installed in the pressure pipeline, and it also protects the corrugated hose. According to the pressure in the pipeline and the different application fields, one or more layers of stainless steel wire or steel strip can be selected to form a high-pressure-resistant corrugated metal hose.
The material of the wire braid is often the same as that of the corrugated hose, and a different material can also be selected.
Ordinary corrugated metal hoses only use a single layer of braid.
Connection fittings connect corrugated hoses and braids together, and at the same time play a role in adapting different connections.
According to the structural form, the connection accessories are roughly divided into three categories: threaded connection, quick connector, and flange.
Threaded connections and quick connectors generally connect small-diameter corrugated metal hoses, and larger-diameter corrugated metal hoses usually are connected by flanges.
A Better Alternative to Rubber Hoses in High Temperature and Pressure Applications
Annular corrugated hose
Helical corrugated hose
Helical: The helical corrugated hose has a helix angle between two adjacent convolutions, and a helical line can connect all the convolutions.
Auunlar: The annular corrugated hoses are formed from seamless or welded pipes. Restricted by the processing method, the length of the annular corrugated hose is usually shorter than that of the helical corrugated hose. The advantages of an annular corrugated hose are good elasticity and low rigidity.
The annular corrugated hose is more widely used than the helical.
The corrugated metal hose and its accessories are mainly made of stainless steel, which ensures excellent temperature resistance and corrosion resistance of the corrugated metal hose. The operating temperature range of corrugated metal hose is extensive, which is -196～600℃. In actual use, select the material of the corrugated metal hose according to the corrosiveness of the pipeline flow medium to ensure the corrosion resistance of the corrugated metal hose.
