Le tuyau en HDPE présente des avantages évidents

2018-11-15

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.

Forte capacité à résister à la pression étrangère

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

Sous les mêmes conditions de charge, les tuyaux ondulés en PEHD à double paroi n'ont besoin que d'une paroi mince pour répondre aux exigences

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.

Construction convenience

Comme le tube ondulé double paroi en PEHD est léger, la manipulation et la connexion sont très pratiques, de sorte que la construction de travaux de maintenance rapides et faciles, dans des délais serrés et dans des conditions de construction médiocres, rend son avantage plus évident.

long lasting

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 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.

Les tuyaux en PEHD doivent supporter une certaine pression, en général pour utiliser une masse moléculaire élevée et les propriétés mécaniques d'une meilleure résine PE, telle que la résine PEHD. La résine LDPE a une faible résistance à la traction, une résistance à la pression médiocre, une rigidité médiocre, une stabilité dimensionnelle médiocre pendant le moulage et des difficultés de raccordement, et ne convient pas comme matériau pour les tuyaux d’alimentation en eau. Cependant, en raison de ses indicateurs de santé plus élevés, le PEBD, en particulier la résine de PEBDL, est devenu un matériau courant pour la production de conduites d’eau potable. LDPE, la viscosité à l'état fondu de la résine LLDPE est petite, sa mobilité est bonne, son traitement est facile et, par conséquent, sa plage de sélection de l'indice de fusion est également large, généralement un MI compris entre 0,3 et 3 g / 10 min.
