The production of polymer poly custom 0202020202020202 polychlorine plastic pipe has the above characteristics, and the price is cheaper than other plastic pipes. As a result, it has a place in the pipe manufacturing industry. Hard PVC pipes are resistant to corrosion by a variety of acids, alkalis, oils and alcohols. The servos of the pipes can be well bonded to each other and are easy to lay. In thermoplastic pipes, the linear expansion coefficient of rigid polychlorine pipes. The compressive strength of this laying pipe reaches a nominal pressure of 16 bar, and it can be sold in segments. In places with high impact strength requirements, it is advisable to use impact-resistant PVC pipes. These high impact strength products are made from a mixture of polychlorine and sexual raw materials. The price of new plastic pipes with impact toughness is higher than that of ordinary hard PVC pipes, and the allowable stress on the pipe wall is also 10 Newtons/mm2. The leg pad is composed of a plate-shaped pad body and a carrying rope. The plate-shaped pad body is made of UHMW/HDPE polymer synthetic material or MC nylon pressed. The four corners of the UPE polymer composite pad support 60mm bear a pressure of 15-18 tons/cm or more. It can be used normally in harsh environments, and is constantly cracked when overloaded. The end of the hand rope is embedded in the pad body for easy carrying and arrangement. MC nylon pressed leg pads have a stronger compression capacity, which can reach 30-45 tons/cm or more. Size: 500*50002 600*60002 800*800 can be customized according to customer requirements.
