Henan Deyuan Rubber and Plastic Products Co., Ltd. produces buried double-layer oil pipelines for gas stations, with a complete range of specifications including Φ32, Φ40, Φ63, Φ75, Φ110, and Φ125 mm. The manufacturer ships directly, offering competitive prices and comprehensive after-sales service, along with a professional installation team available for on-site guidance if needed. Our company not only produces gas station oil pipelines, including double-layer oil pipelines, single-layer oil pipelines, anti-static oil pipelines, but also provides supporting fittings for gas station oil pipelines: welding heads (testing ports), single-layer welded joints, conversion copper joints, double-layer bends, single-layer bends, flanges, conductive plugs, double-layer tees, single-layer tees, double-layer welded joints, double-layer terminal welding heads (testing ports), double-layer terminal welding heads, double-layer terminals, welding machines + tools + pressure testing tools. Installation and Construction of Buried Double-Layer Oil Pipelines for Gas Stations: Our company can send professional technicians to the site to guide the installation. Introduction to Double-Layer Welded Joints for Gas Station Oil Pipelines: The double-layer welded joints for gas station oil pipelines are produced using a multi-layer thermoplastic extrusion process. The pipes are suitable for various types of fuel, pressure oil pipelines, self-priming oil pipelines, unloading pipelines, venting and oil-gas recovery pipelines, and chemical transfer pipelines. The semi-flexible structure of the pipes ensures their strength and durability while also making them easy to install. Pipe Body ---- High-density polyethylene Bonding Layer ---- Bonds polyethylene and EVOH together Seepage Prevention Layer ---- Pure EVOH (ethylene-vinyl alcohol copolymer) According to the position of the EVOH oxygen barrier layer in the double-layer composite pipe, there are three different types of EVOH pipes: A. The inner layer is the EVOH oxygen barrier layer, the outer layer is PE or PEX, with a hot melt adhesive layer between the two layers; B. The inner layer is PE or PEX, the outer layer is the EVOH oxygen barrier layer, with a hot melt adhesive layer between the two layers; C. The inner layer is PE or PEX, the middle layer is the EVOH oxygen barrier layer, and the outer layer is covered with another layer of PE or PEX, with a hot melt adhesive layer between the inner and outer layers. The first two types of EVOH pipes have a three-layer structure, while the latter has a five-layer structure. The production equipment for the five-layer structure EVOH pipes is also correspondingly advanced. Applications of Double-Layer Welded Joints for Gas Station Oil Pipelines: Traditional metal pipelines used in gas stations are prone to corrosion and damage, leading to gasoline leaks that pollute the environment and groundwater. As environmental protection requirements continue to rise, metal pipelines have gradually been replaced by plastic pipelines. The double-layer welded joint system for gas station oil pipelines features a cleaner, safer, stronger, and quicker installation process and has been adopted in a large number of gas station constructions.
The proportion of polyethylene composite pipes used for buried double-layer oil pipelines in developed countries such as Europe and the United States: 100% in the United States, nearly 80% in Europe. Most domestic gas stations still use traditional metal pipelines, with about 5,000 gas stations (foreign-funded) using polyethylene composite pipes, showing a significant gap compared to developed countries in Europe and America. With the increasing environmental protection requirements in China, PetroChina and Sinopec have started to widely use double-layer welded joints for gas station oil pipelines in new and renovated gas stations. Henan Deyuan Rubber and Plastic Products Co., Ltd. is a high-tech enterprise integrating research and development, production, and sales, specializing in the production of buried double-layer oil pipelines for gas stations, oil well pipes, ultra-high molecular weight polyethylene pipes, tunnel escape pipes, steel belt reinforced polyethylene (HDPE) spiral corrugated pipes, HDPE pipes, internal and external coated composite steel pipes, 3PE anti-corrosion pipes, lined pipes (steel-lined PO pipes, steel-lined PE pipes, steel-lined fluorine pipes), and rubber-lined pipes, among other series of multi-specification pipe fittings and pipe products. The products are mainly used in the chemical, electric power, mining, metallurgy, pharmaceutical, water conservancy, municipal, construction, environmental protection, dredging, and coal washing industries.
