Corrugated Metal Hose “Good Flexibility”

What is Corrugated Metal Hose ？

The Single Sphere Rubber Joint Manufacturer Shanghai Songjiang Group Introduce to you: The Corrugated Metal Hose has many advantages such as good flexibility, fatigue resistance, high and low temperature resistance, corrosion resistance and so on. Widely used in petrochemical, steel metallurgy, rubber, machinery, electric power and other industries.

Different Types Of Corrugated Metal Hose

1. Threaded type Corrugated Metal Hose

The joints of metal hoses with a diameter of less than 50 mm are mostly threaded in the case of high working pressure. When the threads are tightened, the inner and outer taper surfaces of the two joints are Tight fit for sealing. The cone angle is generally 60 degrees, and 74 degrees are also useful. The structure has good sealing performance, but the concentricity of the two butt joints must be ensured during installation. In order to solve the problems of repeated disassembly, assembly and difficult concentricity that are often seen in practical projects, the joint can also be designed to match the taper surface and the ball head.

2. Flange type Corrugated Metal Hose

The joints of metal hoses with a diameter of more than 25 mm are mainly flanged under the condition of normal working pressure, and they are sealed in the form of tongue and groove cooperation. The looper flange, which can rotate in the radial direction or slide in the axial direction, connects the two bodies under the action of the tension of the fastening bolts. The structure has good sealing performance, but it is difficult to process and the sealing surface is easy to touch. In special occasions where quick release is required, the holes through which the fastening bolts pass can be cut to form a quick release flange.

3. Quick type Corrugated Metal Hose

For the joints of various metal hoses with a diameter of less than 100 mm, the quick type is generally used under the conditions of use that require quick loading and unloading. It is usually sealed with an “O” ring made of fluoroplastic or a kind of rubber. When the handle is moved to a certain angle, the claw fingers, which are equivalent to multi-thread threads, are locked; the tighter the “O” ring is pressed, the better the sealing performance. This structure is suitable for fires, battlefields and other occasions where quick loading and unloading are required. In a matter of seconds, without any special tools, the first set of connectors can be docked or disassembled.
