Metal hose is a high quality flexible connecting pipe, which is formed by extremely thin, seamless or longitudinal joint through high precision plastic deformation. It has many advantages, such as good softness, fatigue resistance, high and low temperature resistance, corrosion resistance and so on. It is widely used in petrochemical industry, steel metallurgy, rubber, machinery, electricity and other industries. So how can the metal hose be connected properly?
The connection way of metal hose is introduced: the joint of metal hose with a diameter of less than 50 millimeters is mainly threaded. Under the condition of high working pressure, the inner and outer taper surfaces of the two joints are closely matched to achieve the seal after tightening the thread. The cone angle is generally 60 degrees and also useful in 74 degrees. The structure is well sealed, but the concentricity of the two butt parts must be ensured when the installation is installed.
In order to solve the problems that are often seen in the actual project, such as repeated dismantling, loading and not easy to be concentric, the joint can be designed to match the cone with the ball head.
Flange plate: a metal hose joint with a diameter of more than 25 millimeters. Under the general working pressure, it is mainly made of flanges, and it is sealed in the form of tenon grooves. The two body is connected under the action of the fastening bolt pulling force, which can be rotated along the radial direction and can also be slid along the axial direction. The structure has good sealing performance, but it is difficult to process, and the seal face is easily bruised. Special occasions in need of quick release, can be cut through the bolt fastening holes, made quick detachable flange.
Fast type: the joints of various metal hoses with a diameter of less than 100 millimeters are generally used fast under the conditions required for rapid loading and unloading. It is often used to seal the "O" - shaped seal made from fluoroplastics or special rubber. When the hand moves a certain angle, the claw, which is equivalent to the multi head thread, is locked; the tighter the "O" ring is pressed, the better its sealing performance. The structure is most suitable for fire, battlefield and other occasions which must be quickly loaded and unloaded. In a few seconds, a group of joints can be butted or disassembled without the need for any special tools.
Outside the wire metal hose: as the main parts material is austenitic stainless steel hose, thus ensuring the heat resistance and excellent corrosion resistance of the hose, the hose is extremely wide range of working temperature, -196-600 degrees, the pipeline through the hose on Corrosion for stainless steel grades, to ensure that the corrosion resistance of hose the.
