⑴ single bellows on the static load displacement compensation began to use more single corrugated bellows concept, its production is simple and low cost. In ensuring bearing capacity, the amount of compensation, stiffness and fatigue life of the design requirements of the premise, should be preferred single bellows. ⑵ multi-bellows for by alternating loads bellows specification, or more important pipeline, more choice of two or more layers of the bellows. Compared with the single, at the same carrying capacity of corrugated plastic pipe, low stiffness, fatigue or performance. (5) uneven ground, pipe level of inconsistency bellows, forced extrusion, under external pressure is not the same. (6) After installing the logo is not obvious, any damage to the drilling pipe. (7) pending when to clean the filter. (8) When the pressure test is not clean exhaust gas to form a hammer or water hammer. After the test pressure, not timely use, but not the water drained, if in the winter, you can make water pipes freezing. (9) pipe or drill holes through the bottom of the door when entering impurities. As we all know, good or bad installation of pipe products, the length is critical to product life use. After the general pipe products sold, companies will send a professional installer to install, the purpose is to avoid the occurrence of the above. Bellows specifications, Xiong Yu-tai (certified), Datong bellows provided by Xiong Yu Thai plastic products factory.
