HDPE Pipe has excellent chemical stability, anti-aging and resistance to environmental stress cracking performance. The HDPE double-walled bellows produced from it is a flexible tube.
Strong ability to resist foreign pressure
The outer wall is an annular corrugated structure, which greatly increases the ring stiffness of the pipe, thus enhancing the resistance of the pipe to the soil load. In this performance, HDPE Pipe has obvious advantages compared with other pipe.
Low project cost
Under the same load conditions, HDPE double-wall corrugated pipe only need a thin wall can meet the requirements
The Therefore, compared with the same material specifications of the solid wall tube, can save about half of the raw materials, so HDPE Pipe is also lower cost, which is another prominent feature of the pipe.
As the HDPE double-wall corrugated tube light weight, handling and connection are very convenient, so the construction of fast, easy maintenance work, in the tight schedule and poor construction conditions, the advantages of its more obvious.
In the absence of sunshine UV conditions, HDPE Pipe life of up to 50 years.
High density polyethylene, the English name for the "High Density Polyethylene", referred to as "HDPE". HDPE is a high degree of crystallinity, non-polar thermoplastic resin. The appearance of the original HDPE was milky white, in a slight cross-section was a certain degree of translucent. PE has excellent resistance to most of the characteristics of life and industrial chemicals. Certain types of chemicals can produce chemical corrosion, such as corrosive oxidants (concentrated nitric acid), aromatic hydrocarbons (xylene) and halogenated hydrocarbons (carbon tetrachloride). The polymer is non-hygroscopic and has good water vapor resistance and can be used for packaging applications. HDPE has good electrical properties, especially dielectric dielectric strength, making it very suitable for wire and cable. Medium to high molecular weight grade has excellent impact resistance, at room temperature even in the -40F low temperature are so.
HDPE is a thermoplastic polyolefin produced by copolymerization of ethylene. Although HDPE was introduced in 1956, but this plastic has not yet reached a mature level. This common material is also constantly developing its new uses and markets. The thermoplastic resin. The appearance of the original HDPE was milky white, in a slight cross-section was a certain degree of translucent. PE has excellent resistance to most of the characteristics of life and industrial chemicals. Certain types of chemicals can produce chemical corrosion,HDPE Pipe such as corrosive oxidants (concentrated nitric acid), aromatic hydrocarbons (xylene) and halogenated hydrocarbons (carbon tetrachloride). The polymer is not hygroscopic and has good water vapor resistance
PE can be manufactured with a wide range of different processing methods. Including extrusion such as sheet extrusion, film extrusion, pipe or profile extrusion, blow molding, injection molding and rotomoulding.
HDPE pipe is the traditional steel pipe, PVC drinking water pipe replacement products.
HDPE pipe must bear a certain pressure, usually to use a large molecular weight, mechanical properties of better PE resin, such as HDPE resin. LDPE resin has low tensile strength, poor pressure resistance, poor rigidity, poor dimensional stability during molding, and difficulty in connection, and is not suitable as a material for water supply pressure pipes. However, due to its higher health indicators, LDPE, especially LLDPE resin has become a common material for the production of drinking water pipes. LDPE, LLDPE resin melt viscosity is small, good mobility, easy processing, and thus its melt index selection range is also wide, usually MI between 0.3-3g / 10min.
