Henan Deyuan Rubber and Plastic Products Co., Ltd. produces the **75*63 double-layer oil transfer pipe**, with complete specifications including Φ32, Φ40, Φ63, Φ75, Φ110, and Φ125 mm. The manufacturer ships directly, offering low prices and excellent after-sales service, as well as a professional installation team. If needed, we can provide on-site guidance for pipeline installation. The renovation of gas stations has gradually begun nationwide, with cities such as Beijing, Guangzhou, Tibet, and Hebei leading the way. Since 2001, nearly 10,000 gas stations have adopted the **75*63 double-layer oil transfer pipe**. The **75*63 double-layer oil transfer pipe** has also been widely used in petroleum exploration, oil and gas collection and transportation, and petrochemical refining industries, especially in recent years, with rapid development. It is believed that in the near future, with the advancement of the **75*63 double-layer oil transfer pipe**, it could completely replace the traditional seamless steel pipe technology used in gas stations. Our company's **75*63 double-layer oil transfer pipe** engineering cases include: 1. Gas station oil transfer pipe renovation project in Gar County, Tibet: 2000 meters 2. Kaifeng Jingbiao Petrochemical gas station renovation project: 800 meters 3. Beijing Yandong Hongda gas station renovation project: 400 meters (buried gas station double-layer oil transfer pipe) 4. Dongfang Petroleum Equipment Co., Ltd. gas station renovation project in Dingzhou: 1000 meters Comparison of comprehensive performance between **75*63 double-layer oil transfer pipe** and steel pipes: 1. Conductivity - Buried gas station double-layer oil transfer pipe: Inner layer conducts static electricity—effectively eliminates static electricity hazards caused by oil flow; outer layer is insulated—effectively prevents stray currents in the soil from affecting the pipeline. - Seamless steel pipe: Conductor—effectively eliminates static electricity hazards caused by oil flow, but stray currents in the soil may cause electrolytic corrosion of the pipeline. 2. Environmental safety - Buried gas station double-layer oil transfer pipe: The pipe is resistant to corrosion, and the risk of leakage pollution from ground movements is low; it prevents oil leakage from polluting the external environment; the connection method is electric fusion welding with no open flames. - Seamless steel pipe: Strong external environmental corrosion and quality issues of the anti-corrosion layer may pose leakage risks; double-layer sealed seamless steel pipes have not yet been applied in domestic gas stations; the connection method is arc welding, which easily produces open flames. 3. Pipeline handling - Gas station double-layer composite oil transfer pipeline: The pipeline can be installed directly; after installation, there are no residues inside the pipeline, and cleaning is not required. - Seamless steel pipe: Rust removal and anti-corrosion treatments are needed before installation; there are often construction residues inside the pipeline after installation, requiring cleaning. 4. Project cost - Buried gas station double-layer oil transfer pipe: The specific cost is calculated based on project planning and design, with an estimated cost for most gas stations being 30,000 to 80,000 yuan per station (only considering the oil transfer pipeline). - Seamless steel pipe: There are significant differences in quotas across regions, and costs are related to the scale of the gas station. The project cost may be lower, equivalent to, or higher than that of gas station double-layer composite oil transfer pipelines. 1. Prevention of oil leakage - Buried gas station double-layer oil transfer pipe: The permeability of the anti-leak layer is 0 (for gas station pipeline installation). - Seamless steel pipe: No leakage. 2. Corrosion resistance - Gas station double-layer composite oil transfer pipeline: The main material is polyethylene, which is corrosion-resistant. - Seamless steel pipe: The material itself is prone to corrosion, and the corrosion resistance depends on the quality of the external anti-corrosion layer and construction quality. 7. Maintenance/replacement costs - Gas station double-layer composite oil transfer pipeline: 30-year warranty period, no maintenance/replacement required under normal use. - Seamless steel pipe: Average lifespan is shorter, and there are more uncertainties, requiring more maintenance and replacement.
