Polyethylene corrugated pipe, Kaka Electric (certified), bellows

 Corrugated plastic pipe market outlook Yueqing Electric Co. offer Kaka see AD7 bellows from the plastic hose size corrugated plastic pipe market perspective, corrugated plastic pipe market full of huge opportunities. After nearly three decades of corrugated pipes started in equipment, molding technology, technology, special materials and other aspects have gained rapidly. In recent years the plastic corrugated pipes of large diameter direction gradually to carry out, the nation's largest 1200 can already be done. They use material from spreading to the primary for PVC PE, PP and other plastic corrugated pipe production line devices from scratch, there have been a number of domestic plant can produce up to 1200mm diameter corrugated plastic pipe production line. Since the early 1990s China began to introduce the production of this type of pipe, began following the primary small-caliber 110 series, the primary material for PVC, used as the primary communications cable sheathing. Plastics are two classification bellows bellows, one is completely airtight, watertight, such as rocket propellant for transportation, gas, water heaters; the other is to use a continuous strip wound ordinary volume around the bellows for the protection of cables, such as telephone card, the machine, while the lamp bellows is sandwiched in the wire manufacturing process. Classification by forming process ⑴ hydroformed bellows hydroforming is the most common method of forming the bellows. The use of fluid pressure in the tube, the tube is bulging at the limit ring until the ring to appear along the yield AD13 bellows price, and then compress the tube to the desired length. Small diameter bellows adopt this method. ⑵ bellows roll forming roll forming process is mainly used for processing large bellows bellows, is to rely on in the roll forming tube forming wheel, you can roll into a single wave-shaped, and some devices may once into several corrugations. ⑶ mechanical bulging Bellows dilatation of the tube inside the tire tool, 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 a whole, or for complex waveforms, the overall shape is extremely difficult when you have to use more welding forming. Such bellows can not withstand the internal pressure, do not apply for flexible expansion joint segment.
