1. Plasticization difference: UPVC is hard PVC, and a certain amount of modification aid is added on the basis of PVC resin powder to produce a modified material. Therefore, the main difference between UPVC and 100 PVC and soft PVC is that no plasticizer is added, calcium powder is more, and the material has high mechanical strength. 2. Chlorine content difference: CPVC is chlorinated polyvinyl
The cold knowledge is coming: precautions for the use of pe water pipes Due to its unique advantages, pe water supply pipe is widely used in construction water supply, construction drainage and other fields. In order to ensure the ideal use effect of the pipe and avoid other failures during use, we need to pay attention to the following points when using : 1. Welding: When hot-melting, the
1. Urban water supply: PE pipe head has comprehensive advantages such as safety, sanitation and convenient construction, and has become an ideal pipe material for urban water supply. 2. Natural gas and gas transportation: PVC has become the best choice for medium and low-pressure natural gas transportation pipelines due to a series of advantages such as reliable PE connection, stable performanc
Cold knowledge: What you must know about PE water supply pipe PE water supply pipes are commonly used in municipal engineering. It is often necessary to find suitable manufacturers to purchase pipes that meet engineering requirements. When inquiring manufacturers, they often need to provide specific parameter requirements. Many people do not understand the common knowledge of PE water supply pi
Common problems of PE water supply pipe extruder PE pipe is a common profile in building water supply system. With the vigorous development of PE pipe in the Chinese market, the product has not only been limited to building water supply, but has also been gradually developed and applied to many industries, such as: farmland irrigation, urban underground Pipeline laying, ground source heat pumps
PE water supply pipe pressure test method and safety precautions The water pressure test is acceptable for installation of the PE water supply pipe at each section, and the pressure test can only be carried out at the length of l2m on each side of the elbow and tee, and the soil is returned to 5Ocm above the top of the pipe. In order to prevent pipeline displacement, the pipeline pressure test
PE water supply pipe pressure test steps and related precautions The overall operation of PE pipe construction includes pay-off, excavation, welding, pressure test, backfill (not used for excavation), and put into use. The PE pipe construction specification stipulates that the pipeline can be put into use only after the pipeline is completed and passed the pressure test. To standardize the oper
What are the precautions for PE water supply pipes? PE pipes have good flexibility and light weight, so long pipelines can be prefabricated on the ground. When geomorphic conditions permit, ground welding of pipelines can reduce the trench excavation width. The minimum width should be suitable for easy installation and docking. 1.2 In the pipe trench of sand or silt, if it is not easy to make
