Corrugated plastic pipe 1. Introduction corrugated plastic pipe (PA, PE, PP), widely used in machine tools and electrical box control cabinet trace connections, and there are plastic quick connector facilities. Product specifications are AD7.0, AD10.0, AD13.0, AD15.8, AD21.2, AD25.0, AD28.5, AD34.5, AD42.5, AD54.5, color black and gray and character and so on, Products handsome, lightweight, durable, widely used in automotive wiring harness, electronic, mechanical harnesses and other fields, to replace the original PVC and metal sheathing products, a wide range of applications on the market harness sheathing products. 2. Classification plastic bellows two types, one is completely airtight, watertight, for example, for rocket propellant transportation, gas, water heaters; the other is to use a continuous strip wound, ordinary wound Bellows for the protection of cables, such as telephone card, the machine, and the lamp bellows is sandwiched in the wire manufacturing process. Press forming process classification ⑴ hydroformed bellows hydroforming is the most common method for forming bellows. The use of fluid pressure in the tube, is to limit the loop tube bulging, until along the ring appears to yield, and then compress the tube to the desired length. Small diameter bellows adopt this method. [1] ⑵ bellows roll forming roll forming process is mainly used in the manufacture of large bellows, is relying provided in the roll forming tube forming wheel can be rolled into a single wave-shaped, and some can also be a means to a few ripples. ⑶ mechanical bulging Bellows in the tube inside the tire tool dilatation, individually pressed into corrugated expansion, after the initial shaping, then Kun coining customized inside and outside. ⑷ welded bellows for forming wave height is too large or waveform special bellows, the use of stamping and welding processes. When the wave height exceeds the limit, the extension rate of the material forming process does not allow the use of whole, or for complex waveforms, the overall molding is extremely difficult to use more welding forming. Such bellows inability to withstand the internal pressure, the flexible section is not suitable for use as expansion joints. ⑸ bellows forming the deposition process is by electrodeposition method bellows material is deposited onto the mandrel, the mandrel is then corroded. This bellows material is a very soft, pure nickel metal material is non-porous and, therefore, the ability of high vacuum, and can be welded. Expansion joints flexible segment should not use this bellows, because the cost is too high and is limited to nickel material. Classification by layers ⑴ single bellows to the static load displacement compensation from the use of a single layer of corrugated bellows concept, and its production is simple and low cost. In ensuring the bearing capacity, the amount of compensation, stiffness and fatigue life design requirements of the premise, should be preferred single bellows. ⑵ multilayer bellows and subject to alternating loads, or more important pipeline, more choice of two or more layers of the bellows. Compared with the single, at the same carrying capacity, low stiffness, fatigue resistance or. 3, characteristic PA nylon hose (PA), using imported raw materials modification, bellows kinds of high-tech products, high toughness, high impact, bending resistance, high temperature resistance, bright surface, abrasion resistance, chemical corrosion, fire, electrical insulation> 200MΩ, halogen-free environmentally friendly flame retardant widely used in automotive wiring harness, electronic, mechanical harness and other fields. Temperature range: -40 ℃ ~ 140 ℃; short 205 ℃. 4, the application main applications; instrumentation, control cabinets, equipment manufacturing, engineering, installation, train, car, subway, machine tools, automation control and other industries; 5, to see the development from the plastic hose, corrugated plastic pipe market perspective, plastic Corrugated pipe market full of huge opportunities. Corrugated pipe after nearly three decades of deployment, equipment, molding technology, technology, special materials and other aspects have gained rapidly. The products are sold to Shanghai, Beijing, Guangzhou, Shenzhen, Tianjin, Hangzhou, Chongqing, Wuhan, Shenyang, Nanjing, Chengdu, Zhengzhou, Jinan, Changsha, Shijiazhuang, Harbin, Changchun, Fuzhou, Xi'an, Nanchang, Hefei, Kunming, Taiyuan, Nanning, Urumqi, Lanzhou, Nanjing, Wuxi, Suzhou also sold Yancheng, Yangzhou, Taizhou, Nantong, Xuzhou, Changzhou, Zhenjiang, Wuhu, Ma'anshan, Bengbu, Anqing, Huainan, Tongling, Chuzhou, Fuyang, Huaibei, Lu'an, Chaohu, Xuancheng, etc.
