PE Gas Distribution Pipes — Outside diameter 110 mm
Gas Distribution Standards & Quality Requirements
Natural hydrocarbon gas distribution demands the highest engineering safety factors. Piping in this category (Product P003) is manufactured to ISO 4437, EN 1555-2 and the National Iranian Gas Company IGS specification. These pipes are supplied strictly in SDR 11 across PE80 and PE100 grades.
Compounds must demonstrate exceptional resistance to Slow Crack Growth and Rapid Crack Propagation under low-temperature gas expansion. An overall safety factor of at least 2.0 is mandatory in gas pipeline design.
Color Identification, Dimensional Spectrum & Sourcing
Underground utility identification standards require gas lines to be either solid yellow or black with longitudinal co-extruded yellow stripes to ensure immediate visibility during excavation works. The dimensional envelope spans OD 20 mm to 250 mm.
Diameters up to 110 mm are supplied in 100 m and 200 m coils, while sizes from 63 mm upwards are supplied in 6 m and 12 m straight bars. Supplying to gas infrastructure projects requires manufacturer compliance with client inspection protocols; contact our sales engineering team for project submittal documentation.
Electrofusion Jointing in Gas Distribution Grids
In municipal and industrial gas networks, pipe jointing is predominantly executed using electrofusion fittings. Embedded electrical resistance coils, powered by barcode-controlled fusion units, melt the mating polymer surfaces to forge a monolithic, hermetically sealed weld with tensile strength matching the pipe.
Mechanical surface scraping to remove oxidation, degreasing with approved solvents, and proper pipe clamping to eliminate cooling stress are mandatory quality assurance protocols in gas pipeline welding.
PE Gas Distribution Pipes — Frequently Asked Questions
Why are gas pipes supplied exclusively in SDR 11?
The SDR 11 ratio delivers optimal wall thickness and hoop stress capability to resist internal pressure and external ground loads per ISO 4437 safety regulations.
What documentation is required for gas project tenders?
Due to regulatory specifications, please specify the diameter, compound grade (PE80 or PE100), design pressure, and relevant inspection requirements to our sales engineering team.
How are live branch connections made in pressurized gas lines?
Branch connections are performed using electrofusion tapping saddles with integrated internal cutters, allowing under-pressure hot tapping without shutting down gas delivery.
