HDPE-Rohr hat offensichtliche Vorteile

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.

Starke Fähigkeit, fremdem Druck zu widerstehen

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.

Niedrige Projektkosten

Under the same load conditions, HDPE double-wall corrugated pipe only need a thin wall can meet the requirements

Verglichen mit den gleichen Materialspezifikationen des Rohres mit fester Wand kann somit etwa die Hälfte des Rohmaterials eingespart werden, so dass HDPE-Rohr auch kostengünstiger ist, was ein weiteres herausragendes Merkmal des Rohrs ist.

Construction convenience

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.

Lange andauernd

Bei Abwesenheit von Sonnenschein-UV-Bedingungen beträgt die Lebensdauer von HDPE-Rohren bis zu 50 Jahre.

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 ist ein thermoplastisches Polyolefin, das durch Copolymerisation von Ethylen hergestellt wird. HDPE wurde zwar 1956 eingeführt, doch hat dieser Kunststoff noch kein ausgereiftes Niveau erreicht. Dieses gemeinsame Material entwickelt auch ständig neue Anwendungen und Märkte. Das thermoplastische Harz. Das Aussehen des ursprünglichen HDPE war milchig weiß, in einem leichten Querschnitt war es ein gewisses Maß an Durchsichtigkeit. PE hat eine ausgezeichnete Beständigkeit gegen die meisten Eigenschaften von Lebens- und Industriechemikalien. Bestimmte Arten von Chemikalien können chemische Korrosion hervorrufen, HDPE-Rohre, wie ätzende Oxidationsmittel (konzentrierte Salpetersäure), aromatische Kohlenwasserstoffe (Xylol) und halogenierte Kohlenwasserstoffe (Tetrachlorkohlenstoff). Das Polymer ist nicht hygroskopisch und besitzt eine gute Wasserdampfbeständigkeit

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-Rohr ist das traditionelle Stahlrohr, PVC-Trinkwasserrohrersatzprodukte.

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.
