Advantages of Resistance Welded Pipe

Cost-effectiveness: One of the most significant benefits of resistance welded pipes is their cost-effectiveness. Resistance welded pipes are less expensive than seamless pipes, which are produced through a more complicated process. Resistance welded pipes are also more cost-effective than welded pipes made using other methods.

Ease of use: Resistance welded pipes are easy to use, making them a popular choice for industries that require quick and efficient installation. Resistance welded pipes can be easily cut and welded together, which reduces the need for specialized tools and equipment.

Availability: Resistance welded pipes are readily available, making them an attractive option for industries that require a constant supply of pipes. Resistance welded pipes are produced in large quantities, making them widely available from a range of manufacturers.

Strength and durability: Resistance welded pipes are strong and durable, making them suitable for use in a wide range of applications. Resistance welded pipes are made from high-quality steel and are designed to withstand the rigors of use in harsh environments.

Versatility: Resistance welded pipes are versatile, making them suitable for use in a wide range of industries. Resistance welded pipes are used in the construction industry for the construction of buildings and bridges, in the oil and gas industry for the transportation of oil and gas, and in the water supply industry for the transportation of water.

Differences Between Resistance Welded Pipe and HFW steel pipe

Resistance welded pipe welding process refers the heat generated by the resistance to current flow that pass through the jointed metals. So a large current is needed to electrify the whole surface of the steel plate or coil to the length of welding. In the resistance welded pipe welding process, the electric current that pass through the entire conductor is at 50/60 Hz.

HFW welding process is not the same case with the high-frequency process, since it’s only a section of the steel metals is heated by the induction of electric coil. High-frequency is generated by either AC or DC current. In these cases, the constant current welding generator and constant voltage high-frequency welding generator are used.

FAQ

Q: What is electric resistance welded pipe?

A: Electric resistance welded (ERW) pipe is manufactured by cold-forming a sheet of steel into a cylindrical shape. Current is then passed between the two edges of the steel to heat the steel to a point at which the edges are forced together to form a bond without the use of welding filler material.

Q: Is HFW the same as ERW?

A: The primary difference between ERW and HFW lies in their welding principles. While ERW uses resistance heating, HFW employs high-frequency currents that leverage skin and proximity effects.

Q: What is the difference between electric resistance welded pipe and seamless?

A: Seamless pipe is manufactured by extruding the metal to the desired length; therefore ERW pipe have a welded joint in its cross-section, while seamless pipe does not have any joint in its cross-section through-out its length. In Seamless pipe, there are no welding or joints and is manufactured from solid round billets.

Q: What is a primary advantage of electric resistance welded ERW pipes over seamless pipes?

A: The strip is formed into a closed circular shape, and the seam is welded by a heat induction process. ERW pipe is more economical than both UOE and seamless pipes because the process is continuous and has fewer steps, and as a result is more efficient.

Q: What is the difference between ERW and DSAW?

A: An advantage of ERW pipe is that no fusion metals are used and the weld seam cannot be seen or felt. That's opposed to double submerged arc welding (DSAW), which leaves behind an obvious weld bead that must then be eliminated depending on the application.

Q: Does ERW pipe have a seam?

A: Electric resistance welded (ERW) pipe is made from steel coil and the weld seam runs parallel to the pipe. The width of the coil is the same as the circumference of the pipe so diameters are limited to 24 inches.
