These products are a first-choice solution in this sector due to their superior mechanical performance, high safety factor, reliability, resistance to corrosion and abrasion, low total cost, and easy installation.
Natural Gas Distribution
Given the technical requirements of natural gas, polyethylene pipes are among the earliest and most established choices for gas transfer systems in oil, gas, and petrochemical sectors.
For distribution networks, PE gas pipes must be produced from self-colored virgin materials on modern lines equipped with ultrasonic and gravimetric control systems. For field joining, electrofusion welding and approved electrofusion fittings are the primary accepted methods.
Final Summary:
Gas-grade PE100 pipe offers high chemical resistance, strong tensile and pressure performance, long service life, low weight, and easy installation, making it a practical option across petrochemical, oil, and gas infrastructure projects.
- Manufactured using high-grade self-colored raw materials.
- High confidence factor for gas transmission safety.
- 100% sealed performance with leak-free operation.
- IGS approval from the National Iranian Gas Company.
- Use of electrofusion fittings for joining pipe sections.
- Production on advanced modern lines equipped with ultrasonic and gravimetric systems.
- Better resistance to decay, rust, and corrosion compared with steel pipes.
- More cost-effective than steel pipe alternatives.
- Longer service life compared with steel pipes.
- PE gas pipes can be squeeze-controlled during operation, unlike steel pipe systems.
- Natural gas transfer in urban and rural distribution grids.
- Branch and service gas networks for residential and industrial areas.
- Gas feed lines for industrial plants and power facilities.
- Expansion and rehabilitation projects for gas transmission lines.
For PE gas pipe production, all mandatory requirements defined for PE water pipes must also be met. In addition, squeeze-off testing is required according to EN12106 and must be included in the mandatory test list.
