Panda Pipe - Electrical Resistance Welding (ERW) pipes
ERW (Electrical Resistance Welding) pipes are made by cold forming steel coil into a round cylindrical shape. ERW pipe is formed of steel coil, and the weld seam runs parallel to the pipe. Because the breadth of the coil is the same as the circle of the pipe, widths are limited to 24 inches. It is used to transport oil, natural gas, and other vapor-liquid items and may meet a variety of high and low pressure requirements.
Our ERW pipes are manufactured with precision, adhering to the highest industry standards. These pipes, with dimensions customizable to client needs, are produced through an electric resistance welding procedure. We offer a variety of steel grades, each selected for optimal performance. The surface of each pipe is meticulously coated to enhance durability and resistance to environmental factors. Our ERW pipes come with different end types and joint methods, ensuring compatibility with various systems. They undergo rigorous machining for a flawless finish and are widely used in oil and gas industries, among others.
ERW pipes are broadly used by the industries for their excellent properties, durability, and cost-effectiveness. The top application areas of ERW pipes include construction, water and gas conveyance, automobile sector, oil country tubulars (OCTG), and power generation projects. These pipes offer great strength, toughness, and durability to the end-users.

ERW pipe is made in a rolling process, which means that the welded joint is formed during production. This type of pipe is mostly used in low/medium pressure applications such as water/oil transportation. Seamless pipe is made using an extrusion method, which involves inflating a cylindrical metal tube through an opening in a die and then cutting it to lengths. The seamless pipe has no welded joint; thus, it has more strength and higher pressure capacity than equivalent size ERW pipes. As a result, seamless steel pipe is widely used in the high-pressure equipment and thermal boiler industries.
