“Engineered for Absolute Safety & 50+ Years of High-Pressure Gas Distribution”
Puhui HDPE gas pipes are specially designed for premium safety in natural gas and LPG distribution networks. Manufactured strictly in accordance with EN 1555 and ISO 4437 standards, our piping systems ensure zero compromise on joints reliability and pressure resistance.
√ Full Color Coding & Compliance:To meet diverse global municipal regulations, we supply pipes in standard black with co-extruded yellow stripes, as well as solid yellow and solid orange pipelines for high-visibility underground identification.
√ 100% Leak-Free Joints: Utilizing butt fusion and electrofusion welding, the joints become stronger than the pipe itself, eliminating the risk of gas leakage.
√ Premium Virgin Materials: Trackable 100% virgin PE100/PE80 compounds from Borealis and Sinopec provide superior resistance to slow crack growth (SCG) and rapid crack propagation (RCP).
√ Standard Safety Identification: Co-extruded with permanent yellow identification stripes (or available in full yellow) according to international gas safety regulations.
√ Corrosion & Chemical Resistance: Unlike traditional steel pipes, HDPE will not rust, corrode, or tuberculate, drastically reducing long-term maintenance costs.
√ Factory direct quotation and technical support
√ Third-party inspection accepted

Welcome customers to visit the factory, or third party factory inspection is acceptable.
Q: What standards do your HDPE gas pipes comply with?
A: Our HDPE gas pipes are strictly manufactured and tested according to international standards, primarily ISO 4437 and BS EN 1555. We ensure full compliance to guarantee maximum safety and reliability for natural gas transmission and distribution projects.
Q: What raw materials are used in your gas pipes?
A: Gas distribution requires zero compromise on safety. We exclusively use 100% virgin PE80 and PE100 compounds from world-leading suppliers like Borealis and Sinopec. We absolutely do not use any recycled materials in our gas piping systems.
Q: Do you accept third-party factory inspections before shipment?
A: Yes, absolutely. We highly encourage and fully cooperate with third-party testing and factory audits by recognized organizations such as SGS, TUV, or BV. Additionally, we provide our complete in-house quality control testing reports (including Hydrostatic Pressure, Melt Flow Rate, and Elongation tests) for every batch delivery.
Q: Can you customize the pipe dimensions or SDR ratings for our specific project?
A: Yes. We standardly manufacture sizes from 20mm to 630mm in SDR9, SDR11, SDR12.5, and SDR17. However, if your project requires custom wall thicknesses, specific straight lengths (e.g., 5.8m/11.8m for container loading), or specific coil lengths, our engineering team will manufacture them to match your exact technical specifications.
Q: How can I trace the quality of the pipes I purchase?
A: We implement a strict traceability system. Every pipe is permanently marked with a production code, standard, SDR rating, and material type. We can trace every single meter of pipe back to its specific batch of raw material and QA testing record.
Q: Do you provide samples?
A: Yes, we supply test samples. If you are interested in our products and would like to evaluate them before making a bulk purchase, you can request samples. if you need samples, feel free to contact our team.
Q: What is the minimum order quantity for your products?
A: Generally, we have enough stocks for regular diameter & pressure HDPE Pipe and Fittings, pls forward RFQ to our sales team for more details.
