Process Flow

SSAW, which stands for Spirally Submerged Arc Welding, is a type of steel pipe that is manufactured using a spiral seam submerged arc welding technique. This method involves the continuous welding of a narrow strip (or plate) into a cylindrical shape, resulting in a pipe with a spiral seam. SSAW pipes are known for their unique characteristics and manufacturing processes, which have led to their widespread application in various engineering and infrastructure projects.
SSAW pipes are extensively used in the oil and gas industry, particularly in long-distance transportation pipelines such as the West-East Gas Pipeline project in China. They are also utilized in the chemical industry, power generation, heating, water supply and drainage, steam heating, and other long-distance conveyance line projects. Additionally, SSAW pipes find applications in piling, dredging, bridge construction, and steel structure projects.
The specifications of SSAW pipes include outer diameter, wall thickness, and length. The outer diameter ranges from 219.1 to 2032 millimeters, with NPS (Nominal Pipe Size) ranging from 8" to 80" and DN (Diameter Nominal) from 200 to 2000. The wall thickness varies from 6 to 25.4 millimeters, and the length is typically between 6 to 12 meters.
The production of SSAW pipes adheres to national and regional standards to ensure optimal quality and performance. Some of the standards include API 5L, which is primarily used for oil and gas pipelines, and ASTM A53, which specifies the requirements for welded and seamless steel pipes used in high-temperature, high-pressure, and low-temperature applications. EN 10210 is a European standard used for welded steel pipes for pressure purposes.
Surface treatment of SSAW pipes can improve the surface condition, enhance mechanical properties, and extend the service life of the equipment. Proper surface treatment is crucial for the performance and longevity of SSAW pipes in various applications.
In summary, SSAW pipes are an essential component in many industrial applications due to their strength, durability, and adaptability to different environments and conditions. Their manufacturing process, combined with adherence to strict quality standards, makes them a reliable choice for a variety of engineering projects.
