Mechanical bellows mainly have the need to reduce vibration, foundation settlement, and the role of absorbing thermal deformation of the pipeline, which is widely used in aerospace, petrochemical, mining and electronics, machinery and shipbuilding, medical and health care, textile and electronics, energy and construction and other fields. It has the advantages of durability, high temperature resistance, high pressure resistance, anticorrosion, environmental protection and so on. A certain length of metal bellows can also be effective lateral displacement, can effectively solve the foundation settlement or pipe expansion and contraction.
Two, the scope of application:
1. All kinds of pumps, valves, air compressor import and export;
2.? All kinds of fire piping, air conditioning piping, steam piping, etc.
3.? General factory piping and occasions requiring flexible connections;
4. Domestic water piping and heating piping;
5. Mechanical equipment piping needs to dampen vibration and compensate for thermal displacement of the occasion.
Three, structural characteristics:
1. Corrugated pipe shape is "U"-shaped wave, flexible, pressure, sealing, no stress concentration;
2. This product from DN32-DN80 side of the loose set flange, especially DN100 above the use of ringless welding structure, thus avoiding cold hardening. Effectively solve the brittleness of the bellows welding point caused by easy to break, easy to leak and other problems. Extend the service life of the bellows;
3.? There are three - four evenly distributed bowl-shaped lugs on the edge of the flange with tie rods, thus enhancing the working pressure of the bellows;
4.? Each bowl-shaped lugs are equipped with a high-quality shock-absorbing rubber pads to avoid vibration wave transmission through the tie rods, thus improving the performance of the product to absorb pipeline noise and reduce vibration;
5.? Tie rod structure: screws with nuts on both sides are connected to the pipe nut in the center, thus playing a role in adjusting the length of the bellows and restricting the use of the bellows expansion and contraction. Easy to install.
Four, selection instructions:
1.? This product is suitable for all kinds of pumps, valves import and export and pipeline flexible connection;
2.? This product is the first choice to replace the rubber shock absorber throat (soft joint); easy to install, use and maintain;
3. Working temperature -196～450℃, if the temperature exceeds this range, please specify when ordering;
4. The length of the product can be selected according to the actual need;
5. This product has excellent performance of vibration damping and noise absorption, which can absorb the thermal displacement of the pipeline and has small force on the equipment.
