Metal hoses are used in situations where vibration needs to be reduced. They are widely used in the import and export of central air-conditioning pumps, fire pumps, and domestic water supply pumps. They can effectively reduce host vibration, absorb pipeline noise, protect equipment, and extend equipment. Long service life, it has the advantages of durability, high temperature resistance, high pressure resistance, anti-corrosion, and environmental protection. A metal hose of a certain length can also effectively move laterally and can be used in settling or telescopic situations. Pipe diameter: DN15-DN12000
(Thrust-free shock-absorbing corrugated soft joints can also be used)
The stainless steel shock-absorbing corrugated compensator is a product of Shougang Company after years of research and combined with the market According to the needs, stainless steel and rubber are optimized and combined to form a new patented product that is both rigid and soft, durable and environmentally friendly. It is widely used in the import and export of central air-conditioning pumps, fire pumps, and domestic water supply pumps. It can effectively reduce host vibration, absorb pipeline noise, protect equipment, and extend the service life of equipment. It has the advantages of durability, high temperature resistance, high pressure resistance, anti-corrosion, and environmental protection. . It effectively solves the unsanitary, easy aging, unstable pressure resistance, easy delamination, tearing, explosion and other undesirable factors caused by the old rubber soft joints, and solves the worries of the pump room.
2. Scope of application:
1. Import and export of various pumps, valves, and air compressors;
2. Various types of fire piping and air conditioning piping , steam piping, etc.;
3. General factory piping and occasions requiring flexible connections;
4. Domestic water piping and occasions requiring sanitation;
5 . Where mechanical equipment piping needs to absorb shock and compensate for thermal displacement.
3. Structural features:
1. The bellows is an "S" shaped wave, with high flexibility, high rigidity and no stress concentration;
2. This product has a loose flange on one side from DN32 to DN80, especially above DN100, it adopts a ringless welding structure to avoid cold work hardening. Effectively solve the problems of easy breakage and leakage caused by the brittleness of the welded joints of bellows. Extend the service life of the bellows;
3. There are three to four evenly distributed bowl-shaped lugs on the edge of the flange, and are equipped with tie rods to enhance the working pressure of the bellows;
4. Each bowl-shaped lug is equipped with a high-quality shock-absorbing rubber pad to prevent shock waves from being transmitted through the tie rod, thereby improving the product's ability to absorb pipeline noise and reduce vibration;
5. Tie rod structure: The screws with nuts on both sides are connected to the pipe nut in the middle, thereby adjusting the length of the bellows and limiting the expansion and contraction of the bellows. Easy to install.
4. Selection instructions:
1. This product is suitable for flexible connections of various types of pumps, valve inlets and outlets, and pipelines;
2. This product is the first choice to replace the rubber shock absorber hose (soft joint); it is easy to install, use and maintain;
3. Working temperature -196~450℃, if the temperature exceeds this range, please indicate it when ordering;
4. The length of this product can be selected according to actual needs;
5. This product has excellent shock absorption and noise absorption properties, can absorb the thermal displacement of pipelines, and has little force on equipment.
Compensator Generally, the bellows of the compensator is made of thin-walled austenitic stainless steel material (0Crl8Ni9, 1Crl8Ni9Ti). Other materials can also be used according to the customer's working conditions. For example, B315 material is used in catalytic cracking units. When the material of the nozzle and lining tube is carbon steel, the operating temperature range of the expansion joint is -20℃~420℃; when the material of the bellows, nozzle and lining tube is stainless steel, the temperature range of the product is -196 ~700℃.
The compensator is used for the axial, angular and lateral displacement of the pipeline. Pipe diameter: DN15-DN12000
