Municipal pipeline manufacturers which everyone introduce knowledge about pipelines

  Municipal pipeline manufacturersSaid that the municipal pipeline needs to withstand a certain pressure, usually choose the molecular weight, good mechanical properties of PE resin, such as HDPE resin. LDPE resin has low tensile strength, poor pressure resistance, poor rigidity, poor dimensional stability during molding and processing, and difficult connection. It is not suitable as a material for water supply pressure pipes. However, due to its high hygiene index, low density polyethylene, especially LLDPE resin, has become a common material for the production of drinking water pipes.

Municipal pipeline manufacturers said that the application field of municipal pipelines is constantly expanding, and the specifications and models are also increasing. The choice can be made according to its raw materials and performance characteristics. Follow-up you should pay attention to know more about the maintenance of water pipes, so as to give full play to its effectiveness.

Choose the pipeline to be safe and secure, in any case do not want to explode. Municipal pipe is a commonly used water supply pipe. Is it easy to burst pipes? Let's get to know the following about municipal pipeline manufacturers.

Municipal pipeline manufacturers said that the PE (polyethylene) material used in municipal pipelines has the characteristics of high strength, corrosion resistance, and non-toxicity, and is widely used in urban water supply, farmland irrigation, building heating and other fields. The flexibility of PE (polyethylene) material can effectively resist underground movement and end load. On the surface, the strength and rigidity of plastic buried pipes are not as good as cement pipes and metal pipes. But in practical application, plastic buried pipe belongs to "flexible pipe". With proper design and laying construction, plastic buried pipes bear the load together with the surrounding soil. Therefore, the plastic buried pipe can meet the mechanical performance requirements of buried use without reaching the same strength and rigidity as the "steel pipe.

At the same time, the pressure relaxation characteristics of polyethylene can effectively consume stress through deformation, and its actual axial stress level is much lower than the theoretical calculation value. In addition, the elongation at break is generally greater than 500%, and the bending radius can be as small as 20 to 25 times the pipe diameter. It is a kind of high toughness material with strong adaptability to uneven settlement of foundation. These characteristics make it a very good anti-earthquake, anti-foundation settlement and anti-temperature expansion pipe. For example, in the 1995 Kobe earthquake in Japan, municipal pipes and gas pipes are the surviving pipeline system.

As can be seen from the above example, municipal pipelines are difficult to burst under normal use, but we can always hear or see the sound of municipal pipelines bursting. What is the reason? Municipal pipeline manufacturers concluded. In fact, the municipal pipeline explosion is mainly caused by the following situations:

1. Improper operation of pipeline connection and unstable connection

2. The pipe quality is unqualified.

3. Suppress overvoltage.

4. Trench landfill is unqualified.

Therefore, municipal pipeline manufacturers remind everyone that when buying municipal pipelines, they must buy good quality ones, and the use specifications should also be kept in mind. Only in this way can it be ensured that the pipe will not burst during use, thereby reducing maintenance costs.
