Tubo HDPE ha evidenti vantaggi

2018-11-15

HDPE Pipe ha un'eccellente stabilità chimica, anti-invecchiamento e resistenza alle prestazioni di cracking ambientale. Il soffietto a doppia parete HDPE prodotto da esso è un tubo flessibile.

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

Pertanto, confrontato con le stesse specifiche del materiale del tubo a parete solida, è possibile risparmiare circa la metà delle materie prime, quindi il tubo HDPE è anche un costo inferiore, che è un'altra caratteristica importante del tubo.

Convenienza di costruzione

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.

di lunga durata

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.

Il tubo dell'HDPE è il tubo d'acciaio tradizionale, prodotti sostitutivi del tubo dell'acqua potabile del PVC.

Il tubo in HDPE deve sopportare una certa pressione, solitamente per utilizzare un grande peso molecolare, proprietà meccaniche di una migliore resina PE, come la resina HDPE. La resina LDPE ha una bassa resistenza alla trazione, scarsa resistenza alla pressione, scarsa rigidità, scarsa stabilità dimensionale durante lo stampaggio e difficoltà di connessione, e non è adatta come materiale per le tubazioni di mandata dell'acqua. Tuttavia, a causa dei suoi indicatori di salute più elevati, LDPE, in particolare la resina LLDPE è diventata un materiale comune per la produzione di tubi per l'acqua potabile. LDPE, LLDPE resina viscosità della fusione è piccola, buona mobilità, facile elaborazione, e quindi il suo range di selezione dell'indice di fusione è anche ampio, di solito MI tra 0,3-3 g / 10 min.
