Tubo del gas in HDPE resistente alle alte temperature

Introduzione di HDPE Gas Pipe

Polyethylene Gas Pipe (PE gas pipe, short for PE gas pipe) is a pipeline system made of high density polyethylene (HDPE) or medium density polyethylene (MDPE) as raw materials through extrusion molding process, specially designed for the transportation of natural gas, gas di petrolio liquefatto (GPL) and other gas media. Compared with traditional metal pipes, PE gas pipe has become the preferred material in the field of global gas transportation due to its characteristics of light weight, resistenza alla corrosione, strong impact resistance and long life.

Dettagli di HDPE Gas Pipe

Resistenza alla corrosione: PE material has natural resistance to chemical corrosion, electrochemical corrosion and soil microbial erosion, without additional anti-corrosion treatment.

Flexibility and shock resistance: The pipeline has high flexibility, which can adapt to external deformation such as terrain settlement or earthquake, and reduce the risk of leakage.

Servizio di lunga durata: the design life can reach more than 50 anni, far more than the metal pipeline (usually 20-30 anni).

Costruzione conveniente: peso leggero (soltanto 1/8 of the steel pipe), support trenchless construction (such as directional drilling), greatly reduce installation costs.

Buona tenuta: using hot melt connection technology, the interface strength is consistent with the pipe body, and the potential gas leakage is eliminated.

Environmental safety: non tossico e insapore, in line with drinking water contact standards, E 100% riciclabile.

Specifiche di HDPE Gas Pipe

1.Material grading

PE80: Medium density polyethylene, suitable for medium and low pressure gas transmission (≤0.4MPa).

PE100: Polietilene ad alta densità, with higher strength and pressure resistance (up to 1.0MPa), suitable for high pressure long distance transportation.

2. Pipe size

Nota: DSP (Rapporto dimensionale standard) is the ratio of the outer diameter of the pipe to the wall thickness, and the smaller the value, the stronger the pressure resistance.

3. Lunghezza standard

Straight pipe: 6M, 12M (non-standard length can be customized).

Coil pipe: 50m-200m (suitable for small diameter pipe, easy to transport and construction).

4. Color identification

Black pipe body + yellow stripe: international common gas pipeline identification.

Other colors can be customized according to customer requirements (subject to local regulations).

5. International standard certification:

ISO 4437: International standard for buried polyethylene piping systems for gas applications.

IN 1555: European standard for polyethylene piping for gas transmission.

ASTM D2513: American Society for Materials and Testing Standard for Gas Piping.

GB 15558.1-2015: China’s National Standard for polyethylene pipes for Gas use.

Domande frequenti su HDPE Gas Pipe

Q1: How long is the service life of HDPE Gas Pipe?

UN: Under standard working pressure and environmental conditions, the design life of PE gas pipe is 50 anni. The actual life is affected by the installation quality, soil environment and maintenance.

Q2: Can HDPE Gas Pipe withstand high temperature?

UN: PE gas pipe long-term operating temperature limit is +40℃, a breve termine (such as maintenance welding) can withstand +60℃. It is recommended to use heat-resistant materials or add insulation layer in high temperature environment.

Q3: How to connect HDPE Gas Pipe?

UN: Electrofusion and Butt Fusion are mainly used, which need to be operated by professional technicians to ensure tightness.

Q4: Is the HDPE Gas Pipe environmentally friendly?

UN: PE material is non-toxic and harmless, the production process is pollution-free, and can be 100% recycled, in line with EU RoHS and REACH environmental protection standards.

Q5: What are the disadvantages of PE100 Gas Pipe compared with metal pipe?

UN: PE pipes have poor UV resistance (bisogno di essere sepolto) and limited high temperature resistance. Tuttavia, its comprehensive cost performance still has significant advantages in the gas field.
