China HDPE Gas Station Underground Thermoplastic Fuel Composite Pipe Manufacturer
We not only produce standard and custom non-standard composite pipeline products, but also supply a complete series of supporting parts for gas station engineering and all kinds of pipeline fittings. We provide a one-stop procurement solution to meet all your project demands.
Pipe diameter, wall thickness, material, length and pressure parameters can all be customized as required. Suitable for non-standard projects of new gas station construction and renovation. We adopt flexible customized production for all specifications and provide one-stop supply of composite pipes and matching fittings.
Our underground composite pipes for gas stations are made of high-quality anti-corrosion raw materials under standardized full-process production control. Featuring strong compression resistance, oil resistance and anti-aging performance, the pipes stay intact underground without cracking or leakage. All products undergo strict pressure and tightness tests before delivery to guarantee long-term safe operation of fuel pipelines.
We are an officially shortlisted supplier of CNPC (China National Petroleum Corporation) and Sinopec, maintaining in-depth long-term strategic cooperation with both central energy enterprises. Our products strictly comply with the official supply inspection standards of CNPC and Sinopec, supporting mass delivery for new-built and renovated gas station pipeline projects nationwide. All products and service systems have been fully verified by large-scale national energy construction projects.
All construction personnel have more than 10 years of practical experience in pipeline installation. They are proficient in the whole process of laying, connecting and pressure testing of buried composite pipes for gas stations, with standardized and mature construction skills to handle various non-standard site conditions and ensure safe and compliant delivery of pipeline projects.
If you have demands for procurement or project cooperation, please feel free to contact us for consultation and negotiation. We will provide one-on-one Q&A and customize suitable solutions for you.
We manufacture matching connectors and supporting components, delivering a full one-stop pipeline solution from main pipes to fittings.

Detailed FAQs About Composite Pipes
Vohon underground composite pipes have a design service life of 30 years under normal buried conditions. Made of PE100 HDPE with EVOH barrier layer, they resist soil corrosion, fuel permeation, and aging without the need for cathodic protection.
For double-wall pipes, the built-in annular monitoring channel accommodates electronic or liquid sensors for real-time leak detection and alarm. For single-wall pipes, post-installation pressure testing (air or hydrostatic) verifies system integrity. All Vohon pipes undergo strict pressure and tightness tests before delivery.
Vohon underground composite pipes have a rated working pressure of 1.0 MPa and a minimum bursting pressure of 4.0 MPa (SDR11 standard), far exceeding the requirements of gas station dispensers and storage tanks.
Vohon composite pipes feature a permanent conductive inner HDPE layer with surface resistance ≤10⁶ Ω (anti-static and explosion-proof). Static electricity generated by fuel flow is safely dissipated to ground, eliminating spark risk.
Yes. Vohon composite pipes feature an EVOH barrier layer that effectively resists permeation from ethanol-blended gasoline, methanol gasoline, biodiesel, and other alcohol-mixed fuels. Compatible with all common gas station fuels.
Vohon composite pipes operate stably within a temperature range of -40°C to +50°C, adapting to extreme cold and hot climatic conditions worldwide.
Vohon composite pipes use electrofusion welding (EFW) connection. Specialized electrofusion fittings (couplers, elbows, tees, flanges) are fused with the pipe using an electrofusion welder, creating a homogeneous, leak-free joint with no need for open flames or mechanical seals.
