Industrial steel pipes refer to cylindrical structures made of steel that are utilized in various industries. These pipes are constructed from metallic alloys including iron and other metals such as aluminum, manganese, etc., offering greater strength and durability compared to iron pipes.

Due to their longevity, high resistance, and effective performance against corrosion, these pipes are widely used in applications such as water, gas, and oil transmission, making them the most commonly used steel sections. Moreover, these pipes are also utilized in the construction of steel structures including warehouses, buildings, bridges, stadiums, playgrounds, etc.

Types of industrial steel pipes

Industrial steel pipes have various applications in different industries based on their production method, dimensions, thicknesses, tests, and standards. Common types of industrial steel pipes include spiral pipes, welded or sealed pipes, and seamless pipes. These pipes come in different types based on their applications and dimensions, including API gas pipes, water supply pipes, casing pipes, and more.

Advantages of using industrial steel pipes

Advantages of using industrial steel pipes include high mechanical strength, flexibility, versatility in dimensions and lengths, resistance to environmental conditions, economic efficiency, and recyclability. Furthermore, their production according to standards and technical specifications ensures quality and usability in various conditions.

Applications of industrial steel pipes

Industrial steel pipes have always been among the best choices for use in various industries. They are extensively used in industries such as oil and gas, petrochemicals, water and wastewater, civil engineering and urban development, energy transmission, machinery, and processing industries.

Welded Steel Pipes

Welded steel pipes are among the most common types of steel pipes used in industries due to their ability to be produced in various sizes and thicknesses. Steel sheets, after preparation and storage in the production line, are gently bent by multiple rollers. After bringing the two edges of the sheet close together, they are welded together to form a steel pipe. Therefore, these pipes are also called welded pipes or ERW (Electric Resistance Welded) pipes. The two edges of the sheet in welded pipes are usually welded together using either electric resistance welding (ERW) or submerged arc welding (SAW) methods.

ERW Welding

Electric Resistance Welding (ERW) is a welding process in which the edges of the steel sheet melt together due to the passage of electric current between them. The absence of secondary material for welding reduces stress, increases weld strength, and reduces weld defects during inspection. It is common to remove internal and external burrs caused by welding using various technologies for different purposes.

FGA Company produces steel pipes by electric resistance welding (ERW) method, using the advanced Norwegian EFD Weldac 1500 device. by relying on the localized technology, it can remove internal and external welding beads.

Advantages of ERW welding

Direct welding and non-use of secondary material increases the strength and durability of this pipe compared to similar pipes. Higher accuracy and speed and lower tolerance in diameter and thickness in the ERW welding method leads to the production of steel pipes in a higher volume and also reduces production costs. The smooth and uniform welding seam that reduces friction and stable quality is also one of the many advantages of ERW welded steel pipes.
