PE pipe has medium density polyethylene pipes and high-density polyethylene pipe. SDR11 divided according to the thickness and SDR17.6 series. The former applies to transport gaseous artificial gas, natural gas, liquefied petroleum gas, Shandong PPR pipe equipment, which is mainly used to transport natural gas. Compare and steel, the construction process is simple, there is a certain degree of flexibility, but the main thing is not used for anti-corrosion treatment, will save a lot of processes. Shortcomings instrumental inferior steel PPR pipe equipment, construction special attention thermal heating safe distance, and not exposed to air in the sun, and sensitive to chemicals PPR pipe equipment manufacturers, to prevent damage caused by leaking sewage pipes. PE sewage outfall pipe with PE also known as high-density polyethylene pipe, namely English: HDPE. Such tubes are often used as a municipal engineering preferred pipe, mainly used in: Sewage treatment industry. Because of its wear-resistant, anti-acid corrosion, high temperature, high pressure and other characteristics, and gradually replaced the steel, cement pipes and other traditional pipe position in the market, especially since this pipe, light weight and easy to install mobile PPR pipe equipment and machinery is the first choice of new materials. Users select the pipeline when this material needs special attention to the following points: 1. Select the plastic pipe materials should pay special attention. There are thousands of polyethylene grades of raw materials, the market there is low as a few thousand dollars a ton of raw material, this material can not be construction products, otherwise rework caused huge losses. 2. Use the pipe manufacturer should take formal professional manufacturer prevail. 3. When the option to purchase PE pipe manufacturers want the field to inspect to see whether they have the production capacity.
