Introduction to the connection method of stainless steel metal corrugated hose: The joints of stainless steel metal corrugated hoses with a diameter of 50 mm or less are mostly threaded under the condition of high working pressure. When the threads are tightened, the two joints are connected The inner and outer taper surfaces of the tube are closely matched to achieve sealing. The cone angle is generally 60 degrees, and 74 degrees is also useful. The structure has good sealing performance, but the concentricity of the two mating parts must be ensured during installation.
In order to solve the problems of repeated disassembly and assembly and difficulty in concentricity that are often seen in practical engineering, the joint can also be designed to match the cone and the ball head.
Flange type: The joint of the stainless steel metal corrugated hose with a diameter of 25 mm or more. Under the condition of general working pressure, the flange type is the main type, which is sealed in the form of tongue and groove fit. The loop 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 bolt. The structure has good sealing performance, but it is difficult to process and the sealing surface is easy to scratch. In special occasions where quick removal is required, the holes through which the fastening bolts pass can be cut to make a quick release flange.
Quick type: the joints of various stainless steel metal corrugated hoses with a diameter of less than 100 mm, under the conditions of use that require fast loading and unloading, generally use the fast type. It is usually sealed with an 'O'-shaped sealing ring made of fluoroplastic or special rubber. When the handle is moved at a certain angle, the claw fingers equivalent to the multi-threaded thread are locked; the tighter the 'O'-shaped sealing ring is pressed, the better the sealing performance. This structure is more suitable for fire scenes, battlefields and other occasions where quick loading and unloading is necessary. In a few seconds, a set of joints can be connected or disconnected without using any special tools.
Upper outer wire stainless steel metal corrugated hose: Since the main parts of the hose are made of austenitic stainless steel, it ensures the excellent temperature resistance and corrosion resistance of the hose, and the hose has a very wide operating temperature range , Is -196-600 degrees, the hose used selects the applicable stainless steel grade according to the corrosiveness of the medium passing through the pipeline to ensure the corrosion resistance of the hose.
