X42-X100 High Strength SSAW Pipe Supply from AGICO Steel

What is SSAW Steel Pipe

SSAW (Spiral Submerged Arc Welded Pipe) is a welded steel pipe manufactured by a spiral forming process. The core process is to roll the hot-rolled steel strip into a tube blank at a certain spiral angle (forming angle), and then use submerged arc welding technology to weld the internal and external welds.

SSAW Steel Pipe for Sale

Common specifications and standards
Commonly used steel grades: API 5L X42~X100 (yield strength 290~550MPa).
Steel standards: API 5L, ISO 3183, GB/T 9711.
Anti-corrosion options: 3PE, coal tar epoxy, galvanized.

SSAW Pipe Manufacture Process Characteristics:

Spiral forming: The steel strip is continuously spirally curled, with high material utilization, suitable for producing large-diameter steel pipes (maximum diameter can reach more than 3 meters).
Submerged arc welding: The welding process is carried out under the flux layer, the weld quality is stable, and it is suitable for the production of thick-walled pipes (wall thickness is usually 6~25.4mm).
Low cost: Compared with straight seam welded pipe (LSAW), spiral welded pipe equipment investment is low and it is suitable for mass production of medium and low-pressure pipelines.

Main Applications of SSAW Steel Pipe

SSAW steel pipes are widely used in oil, natural gas, water conservancy, construction, chemical industry, electric power, marine and municipal engineering and other fields due to their high strength, corrosion resistance and long life.

Application scenarios:
Onshore medium and low pressure oil and gas long-distance pipelines (pressure is usually ≤12MPa).
Natural gas urban pipeline branch line.
Advantages:
Large diameter (Φ219~Φ3048mm) meets the needs of long-distance transportation.
3PE/FBE anti-corrosion coating can cope with soil corrosion environment.

Oil and Gas Transportation

Application scenarios:
Building foundation pit support piles and bridge pile foundations.
Port terminal support structure.
Advantages:
The spiral weld structure enhances the ability to resist radial pressure.
High diameter-to-thickness ratio (D/t) design saves material.

Structural Support and Pile Foundation

Application scenarios:
Large water pipelines (such as the South-to-North Water Diversion Project).
Municipal water supply/drainage network.
Advantages:
Low cost, suitable for large-span water conservancy projects.
The inner wall is smooth and the water flow resistance is small.
