Longitudinally submerged arc welding pipe, commonly known as LSAW/ SAWL pipe.
LSAW pipe is made by bending and welding steel plates together, creating a cylinder shape. The welding process involves a submerged arc, which creates a strong and durable connection between the plates.
One of the main advantages of LSAW pipe is that it can be used to construct large and complex structures. Due to its ability to produce large diameter pipes, LSAW pipes are a popular choice for pipeline projects, including oil and gas transmission lines and water pipelines.
Another advantage of LSAW pipe is its high resistance to corrosion and erosion. The submerged arc welding process creates a protective layer that helps to prevent rust and other forms of damage, which makes LSAW pipes ideal for use in harsh environments.
In addition, LSAW pipe has a smoother surface compared to other types of welded pipes, which reduces the frictional resistance of the fluid or gas passing through the pipeline. This makes LSAW pipes more efficient for transportation purposes.
All in all, LSAW pipe is a cost-effective and reliable choice for various industrial applications. Its durability, resistance to corrosion and erosion, and ability to construct large structures make it an attractive option for companies to consider.
MADING PROCESS
PRODUCE STANDARD: API 5L, GRADE: Grade B, X42, X52, X56, X60, X65, and X70
1. API 5L, GRADE: Grade B, X42, X52, X56, X60, X65, and X70: This is one of the most commonly used standards for LSAW pipes. Produced by the American Petroleum Institute, it ensures high quality and durability for pipes used in the oil and gas industry.
2. ASTM A252 Standard: This standard is used for LSAW pipes used in piling and structural applications. ASTM A252 pipes are produced in three grades: Grade 1, Grade 2, and Grade 3. These grades offer high tensile strength and are ideal for use in deep foundations and offshore structures.
3. EN10219 Standard: This is a European standard used for LSAW pipes produced for general structural purposes. EN10219 pipes come in different grades, including S235JRH, S275J0H, S275J2H, S355J0H, S355J2H, S355K2H, and S460NH. These grades offer excellent weldability, formability, and corrosion resistance, making them suitable for various construction applications.
4. GB/T3091-2008 Standard: This is a Chinese standard used for LSAW pipes produced for water supply and drainage purposes. GB/T3091-2008 pipes are produced in three grades: Q195, Q215, and Q235. These grades offer good mechanical properties and are resistant to corrosion, making them ideal for water supply applications.
5. DIN 2458 Standard: This is a German standard used for LSAW pipes produced for general structural purposes. DIN 2458 pipes come in different grades, including St37.2, St44.2, and St52.3. These grades offer high strength and durability, making them ideal for use in construction and infrastructure projects.
