Oil and gas transmission steel pipes are the core pipe materials for transporting crude oil and natural gas. They possess high strength, high toughness, corrosion resistance, and excellent weldability, and are widely used in various scenarios such as long-distance onshore pipelines, subsea pipelines, and oilfield gathering and transportation systems. Our company has been deeply involved in the research and development and production of oil and gas transmission steel pipes for many years, focusing on the production and manufacturing of steel pipes. Our products meet mainstream international standards and are precisely matched to the differentiated needs of various oil and gas transmission projects worldwide.
Our oil and gas transmission steel pipes strictly adhere to international standards such as API 5L and ISO 3183. We can also adjust parameters to meet specific project needs, ensuring perfect compatibility with actual conditions. Standard product parameters are as follows:
Pipe type: Straight seam submerged arc welded steel pipe. Mature production processes guarantee product quality, suitable for long-distance oil and gas pipelines.
Outer diameter range: φ21.3mm - φ2200mm, covering all scenarios from small to large diameter long-distance pipelines.
Wall thickness range: 2.5mm - 60mm, with wall thickness tolerance controlled within ±1%. Thickened pipes can be customized according to transmission pressure, media characteristics, and laying environment.
Length range: 6m - 18.3m. Standard lengths are 12m and 18m. Special lengths can be customized according to transportation conditions and construction requirements to reduce on-site welding workload.
Mechanical properties: Yield strength ≥290MPa - ≥550MPa, tensile strength ≥415MPa - With a strength of ≥625MPa and an elongation of ≥20%, it exhibits excellent low-temperature impact toughness, making it suitable for construction needs in cold regions. Connection methods include welding, threaded connections, and flange connections. The appropriate connection method can be selected based on the construction scenario. Threaded and flange connections facilitate on-site installation and disassembly, enhancing construction flexibility. Welded connections are suitable for high-pressure, long-distance pipelines, ensuring connection sealing and strength.
To ensure the quality and delivery time of our oil and gas transmission steel pipes, our company has established a standardized customization process. This allows clients to clearly understand the production progress, and the specific production process is as follows:
Requirement Communication:Clients provide project drawings, parameter requirements, material requirements, delivery timelines, and other relevant information. Our company will assign professional technical personnel to handle the communication.
Solution Design:Based on the specific project situation, we conduct a feasibility analysis and provide a detailed customization solution until the client is satisfied.
Sample Production:After the client confirms the final solution, we will produce samples according to the solution. The samples undergo comprehensive testing and, after meeting the client's requirements, are delivered for acceptance.
Mass Production:After the client confirms the samples, mass production begins. The entire production process strictly adheres to international standards, and we synchronize the production progress with the client in real time.
Finished Product Inspection:Completed products undergo comprehensive testing. Upon passing the inspection, a professional test report is issued.
Packaging and Transportation:We provide professional packaging according to the client's requirements and arrange suitable logistics transportation methods based on the client's actual destination. During transportation, the client can track the shipment progress in real time, ensuring timely and high-quality delivery.
