HDPE Pipe Has Obvious Advantages

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.

Strong ability to resist foreign pressure

Dinding luar adalah struktur bergelombang beralun, yang sangat meningkatkan cincin kekukuhan paip, sehingga meningkatkan ketahanan paip ke beban tanah. Dalam prestasi ini, HDPE Pipe mempunyai kelebihan jelas berbanding dengan paip lain.

Kos projek yang rendah

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.

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 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 boleh dihasilkan dengan pelbagai kaedah pemprosesan yang berbeza. Termasuk penyemperitan seperti penyemperitan lembaran, penyemperitan filem, penyemperitan paip atau profil, acuan tamparan, pengacuan suntikan dan rotomoulding.

HDPE pipe is the traditional steel pipe, PVC drinking water pipe replacement products.

Pipa HDPE mesti menanggung tekanan tertentu, biasanya menggunakan berat molekul yang besar, sifat mekanik resin PE yang lebih baik, seperti resin HDPE. Resin LDPE mempunyai kekuatan tegangan yang rendah, rintangan tekanan yang lemah, ketegaran yang lemah, kestabilan dimensi yang rendah semasa membentuk, dan kesukaran sambungan dan tidak sesuai sebagai bahan untuk paip tekanan bekalan air. Walau bagaimanapun, disebabkan oleh penunjuk kesihatan yang lebih tinggi, LDPE, terutamanya resin LLDPE telah menjadi bahan biasa bagi pengeluaran paip air minuman. LDPE, LLDPE resin mencairkan kelikatan adalah kecil, mobiliti yang baik, pemprosesan yang mudah, dan dengan itu seleksi pemilihan indeks lebat juga luas, biasanya MI antara 0.3-3g / 10min.
