Raw Materials of SSAW Steel Pipe

The raw materials used in the manufacturing of Submerged Arc Welded (SAW) steel pipes, including Spiral Submerged Arc Welded (SSAW) steel pipes, typically consist of the following.

Steel Coils:

The primary raw material for SSAW steel pipes is steel coils. These coils are usually made from low-carbon or low-alloy steel, and the specific grade depends on the intended application and requirements of the finished pipe. Common grades include API 5L Grade B, X42, X46, X52, X56, X60, and others.

Pipe Ends and Fittings:

Pipe ends and fittings, such as flanges and couplings, are often made from steel as well. These components are used to connect and terminate the pipes in various applications.

Welding Flux and Wire:

Submerged Arc Welding (SAW) is the primary welding process used in the manufacturing of SSAW steel pipes. Welding flux and wire are used in this process. The flux helps create a protective atmosphere around the welding area, and the wire serves as the electrode.

Anti-Corrosion Coating:

In some cases, the external surface of SSAW steel pipes may be coated with anti-corrosion materials to protect against environmental elements. This coating can include materials like epoxy, polyethylene, or other corrosion-resistant compounds.

Pipe Coating Materials:

Depending on the application, SSAW steel pipes may undergo additional coating processes. Internal coatings, such as epoxy or cement mortar lining, may be applied to protect against corrosion or to meet specific industry requirements.

Backing Rings and Reinforcement Materials:

For certain applications, backing rings and reinforcement materials may be used to strengthen the pipe joints and ensure the integrity of the welds.

Anti-Rust Oil or Paint:

To prevent the raw steel coils from rusting or corroding during storage and transportation, a layer of anti-rust oil or paint may be applied.
