The following to tell you about the temperature of the PE water supply pipe and the development trend
The following to tell you about the temperature of the PE water supply pipe and the development trend When customers often consult PE pipes, they often mention the temperature resistance of PE water supply pipes and ask if they can receive hot water. Usually PE pipes can withstand 90 and can be used safely in the temperature range of -60-60. However, do not think that PE pipes can withstand 60 and are used as hot water pipes. You need to reserve 20% of the space for storage. If you use them for a long time at high temperature, any information is available under overload.
Let's talk about it below.pe water supply pipeThe temperature and development trend
Does the temperature of ordinary PE water supply pipe have an impact?
When customers often consult PE pipes, they often mention the temperature resistance of PE water supply pipes and ask if they can receive hot water. Usually PE pipes can withstand 90 and can be used safely in the temperature range of -60-60. However, do not think that PE pipes can withstand 60 and are used as hot water pipes. You need to reserve 20% of the space for storage. If you use them for a long time at high temperature, any information is available under overload.
From the data analysis of the temperature resistance of PE pipe, it is well known that PE resin is usedPE water supply pipeDue to different polymerization conditions such as pressure and temperature, PE resin is polymerized from monomer ethylene. After polymerization under different conditions, resins with different densities can be obtained. Therefore, there are polyethylene, medium density polyethylene and high density polyethylene. When processing different types of PE pipes, different resin brands are selected according to different application conditions, and the requirements for extruders and molds are also different.
Generally, PE resin with good mechanical properties and high molecular weight should be selected, and PVC of aggressive PE pipe for water supply and steel pipe for drinking water pipeline should be used instead. Water supply pipe can accept certain pressure, such as HDPE resin, while LDPE resin has poor pressure resistance, low tensile strength, poor rigidity, poor dimensional stability during molding and processing, difficult connection, and is not suitable as material for water supply pressure pipe.
PE water supply pipe is a new trend in the development of water supply pipeline industry
PE is a kind of plastic pipe with rapid development of plastic building materials market in recent years. PE, with its unique performance advantages, dominates the plastic pipe industry and gradually replaces the traditional pipe. It takes galvanized steel pipe and iron pipe as its position. PE pipe is a new type of pipe, which is made of special polyethylene and extruded by plastic extruder. It has excellent corrosion resistance, stress cracking resistance and flexibility.
The polyethylene molecular structure of the polyethylene water supply pipe has high stability and can resist most chemical corrosion. The chemicals in the soil will not degrade the pipe, so there is no need for secondary anti-corrosion equipment. In addition, it will not promote algae, bacteria or The growth of fungi ensures water quality. The PE water supply pipe will not crack during installation and construction in winter, because it is an inert material, it can resist various chemical media and does not require anti-corrosion protection, the chemicals in the soil will not cause any degradation to the pipeline, and will not rot, rust and corrosion.
PE water supply pipeThe inner wall is smooth, its smooth inner surface and non-adhesion characteristics ensure that the polyethylene pipe has higher conveying capacity than the traditional pipe, and at the same time reduces the pressure loss and energy consumption of water supply. The PE pipe has strong sealing performance, and dirt will not pass through the outer wall of the pipe. And welded joints enter the pipeline, fundamentally protect the water quality. In the transformation of the old city water supply and drainage system, the actual temperature of the PE pipe should not exceed 40 degrees, and the nominal pressure should be less than 1.6MPA, usually used for pressure water delivery and drinking water delivery.
