Paip gas PE Ciri-ciri:
* Corrosion. Polyethylene is an inert material, except for a few strong oxidant, can be resistant to a variety of aggressive chemical media, no electrochemical corrosion, no coating.
* Does not leak. PE gas pipeline mainly welding connection (hot melt connection or fused connection), compared with the rubber ring type joints or other mechanical joints, is not dangerous because of distortions caused by leaking joints exist.
* Good resistance to scratches capacity. Effective against scratches caused by stress concentration in the material, may greatly reduce the pipeline damage.
* Ketangguhan tinggi. Pipa gas PE adalah paip keliatan yang tinggi, pemanjangan pada pemisahan pada umumnya lebih daripada 500 peratus, berdasarkan keupayaan paip untuk menyesuaikan diri dengan penyelesaian tidak sekata yang sangat kuat. Adakah prestasi seismik yang sangat baik dalam perancangan.
* Excellent flexibility. Flexible polyethylene PE gas pipe can make the disk volume. Not slotted for construction, easy to PE gas pipeline in accordance with the requirements of the construction methods were changed.
* Advanced fused pipe structure. Non-exposed spiral heating wire to ensure the weld zone uniform heat conduction, and effectively put an end to the short circuit occurs when the pipe inserted into the phenomenon, while avoiding an exposed electric wire prone to aging corrosion defects and pipe inner wall smooth, easy to install .
* Good resistance to rapid crack pass. Rapid crack pipe refers accidental crack in the pipeline, at a speed of several hundred crack m / s growth, resulting in tens of meters or even a large instantaneous km pipe rupture accident. Actual use has not yet found a fast split polyethylene gas pipe.
* Long life, up to 50 years.
Our company using high quality raw materials to produce PE gas pipe, with production of PE gas pipe pressure piping components necessary for the production license of special equipment manufacturing license, manufacture caliber de20-1000mm, reputation-based, improve services,welcome to contact us.
