High-Temperature Resistant HDPE Gas Pipe

Uvođenje HDPE plinska cijev

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, ukapljeni naftni plin (LPG) 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, otpornost na koroziju, strong impact resistance and long life.

Pojedinosti o HDPE plinska cijev

Otpornost na koroziju: 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.

Dugotrajna usluga: the design life can reach more than 50 godina, far more than the metal pipeline (obično 20-30 godina).

Pogodna konstrukcija: mala težina (samo 1/8 of the steel pipe), support trenchless construction (such as directional drilling), greatly reduce installation costs.

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

Environmental safety: non-toxic and tasteless, in line with drinking water contact standards, i 100% reciklirati.

Specifikacije za HDPE plinska cijev

1.Material grading

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

PE100: Polietilen visoke gustoće, with higher strength and pressure resistance (up to 1.0MPa), suitable for high pressure long distance transportation.

2. Pipe size

Bilješka: SDR (Standardni omjer dimenzija) 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. Standard length

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.

U 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.

FAQ od HDPE plinska cijev

P1: How long is the service life of HDPE plinska cijev?

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

Q2: Can HDPE plinska cijev withstand high temperature?

A: PE gas pipe long-term operating temperature limit is +40℃, kratkoročni (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 plinska cijev?

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

Q4: Is the HDPE plinska cijev environmentally friendly?

A: 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.

P5: What are the disadvantages of PE100 Gas Pipe compared with metal pipe?

A: PE pipes have poor UV resistance (need to be buried) and limited high temperature resistance. Međutim, its comprehensive cost performance still has significant advantages in the gas field.
