HDPE rør har tydelige fordele

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.

Stærk evne til at modstå fremmed tryk

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.

Lav projektomkostninger

Under de samme belastningsforhold behøver HDPE dobbeltvægs bølgepap kun en tyndvæg, der opfylder kravene

Derfor kan i sammenligning med de samme materialespecifikationer for det faste vægrør spare omkring halvdelen af ​​råmaterialerne, så HDPE Pipe er også lavere omkostninger, hvilket er et andet fremtrædende træk ved røret.

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.

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 er en termoplastisk polyolefin fremstillet ved copolymerisation af ethylen. Selvom HDPE blev introduceret i 1956, men denne plastik har endnu ikke nået et modent niveau. Dette fælles materiale udvikler også konstant sine nye anvendelser og markeder. Den termoplastiske harpiks. Udseendet af den oprindelige HDPE var mælkehvidt, i et lille tværsnit var en vis grad af gennemskinnelig. PE har fremragende modstand mod de fleste kendetegn ved livs- og industrikemikalier. Visse typer af kemikalier kan producere kemisk korrosion, HDPE rør som korrosive oxidanter (koncentreret salpetersyre), aromatiske carbonhydrider (xylen) og halogenerede carbonhydrider (carbontetrachlorid). Polymeren er ikke hygroskopisk og har god vanddampresistens

PE kan fremstilles med en bred vifte af forskellige behandlingsmetoder. Inklusiv ekstrudering, såsom arkekstrudering, filmekstrudering, rør- eller profilekstrudering, blæsestøbning, sprøjtestøbning og rotomoulding.

HDPE rør er det traditionelle stålrør, PVC drikkevandspip erstatningsprodukter.

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.
