SSAW Steel Pipes play an important role in the field of oil and gas transportation with their many advantages.

Long-distance oil and gas transportation trunk lines on land

In long-distance oil and gas transportation on land, SSAW steel pipes are often used as trunk pipelines. Its spiral weld structure gives the steel pipes higher strength and good pressure bearing capacity, which can meet the needs of large-diameter and high-pressure oil and gas transportation. For example, in my country's large-scale energy transportation projects such as West-East Gas Transmission and West-East Oil Transmission, SSAW steel pipes are widely used. These trunk pipelines continuously transport the rich oil and gas resources in the western region to the economically developed eastern regions. Large-diameter SSAW steel pipes can effectively reduce the pressure loss during transportation and improve transportation efficiency. At the same time, through advanced anti-corrosion coating technology and cathodic protection measures, it is ensured that the steel pipes can operate stably for a long time under different geological conditions and environments, ensuring the safety and reliability of energy transportation.

Inside the oil and gas field, SSAW steel pipes are widely used in the gathering and transportation pipeline network system. The oil and gas extracted from oil wells and gas wells are first collected to the processing station through the gathering and transportation pipeline for preliminary treatment. SSAW steel pipes can flexibly adapt to the complex terrain and layout inside the oil and gas field because they can be customized with different pipe diameters and wall thicknesses according to actual needs. During the gathering and transportation process, oil and gas may contain a certain amount of corrosive substances, such as hydrogen sulfide, carbon dioxide, etc., as well as associated water. In view of this situation, SSAW steel pipes can be made of corrosion-resistant materials or undergo special anti-corrosion treatments, such as lining with corrosion-resistant alloys and externally coated with epoxy coal tar coatings, etc., to effectively resist corrosion, ensure the normal operation of the gathering and transportation pipeline network, and safely and efficiently transport the extracted oil and gas to the processing facilities.

Pipelines crossing complex geological areas

When oil and gas pipelines need to cross complex geological areas such as rivers, mountains, and swamps, SSAW steel pipes become an ideal choice due to their good flexibility and welding performance. When crossing a river, directional drilling and other construction techniques are usually used to pass the SSAW steel pipe through the bottom of the riverbed. Its continuous spiral weld makes the steel pipe less likely to crack during bending, and can meet the requirements of directional drilling construction for the bending radius of the pipeline. When crossing mountains, SSAW steel pipes can be welded on site to adapt to complex terrain changes and ensure the continuity and sealing of the pipeline. For crossing soft geological areas such as swamps, SSAW steel pipes can increase the wall thickness or adopt special foundation treatment measures to improve the stability of the pipeline and ensure that oil and gas transportation is not affected by geological conditions.

Offshore oil and gas field transmission pipelines

In the development of offshore oil and gas fields, SSAW steel pipes are also important transmission pipes. SSAW steel pipes are often used for long-distance transmission pipelines from offshore oil and gas platforms to land terminals, as well as connecting pipelines between platforms. In the marine environment, seawater is highly corrosive, and the pipeline needs to withstand dynamic loads such as waves and currents. Therefore, SSAW steel pipes need to be strictly anti-corrosion treated before application, such as using 3LPE anti-corrosion coating combined with cathodic protection to improve their corrosion resistance. At the same time, its high strength and good welding performance enable it to reliably transport the extracted oil and gas to land in harsh offshore environments, providing key support for the development and utilization of offshore oil and gas resources.
