EN 10210 Pipe Welding Type

Home > Blog > EN 10210 Pipe Welding Type

The technical delivery requirements for round, square, rectangular, and oval hot-worked hollow profiles made of non-alloyed, fine-grained steel are outlined in the European standard EN 10210. Due to their strong mechanical properties and adaptability, these pipes are utilized extensively in a variety of industries. The design of the EN10210 Pipe line is significantly influenced by the welding process. The advantages and characteristics of EN 10210 pipeline, as well as the application of various welding techniques, are discussed in this paper.

EN10210 Pipe

ERW(Electrical Resistance Weld):

Resistance welding (ERW) is the most common method utilized in the production of EN 10210 pipes. The edges of the rolled steel strip are joined and welded in this manner using electric current. At the point of contact, the resistance melts the metal, resulting in a continuous weld that runs the length of the pipe.

When it comes to making EN 10210 pipes, ERW has a lot of advantages. Thanks to the quick and effective process, pipes can be made quickly and with consistent weld quality. Due to the narrow and smooth weld seam, ERW typically produces pipes with a good surface finish and dimensional accuracy. Pipes with thinner wall thicknesses and smaller diameters perform best with this welding technique.

In structural applications such as building frames, scaffolding, and light poles, EN 10210 tubes made of ERW are frequently utilized. Because the process is cost-effective for mass production, ERW pipelines are an economical choice for many construction projects. However, it is important to keep in mind that ERW tubes may not be suitable for applications requiring extremely high pressure resistance due to their thin wall thickness.

HFW(High Frequency Weld):

For making EN 10210 pipes, High Frequency Welding, or HFW for short, is a more advanced version of ERW. Before the steel strip's edges are pressed together to form the weld, a high-frequency electrical current is used to heat them. The welding process becomes more precise and manageable as a result of the heat being concentrated at the edges by the high-frequency current.

When making EN10210 Pipe, HFW has a number of advantages over conventional ERW. The narrower heat-affected zone of the concentrated heat input may improve the weld's mechanical properties. Higher welding speeds are made possible by the method, which improves production efficiency. Additionally, HFW is able to produce pipes with walls that are thicker than those produced by standard ERW, which broadens the applications for these pipes.

Oil and gas pipelines, pressure vessels, and structural parts for heavy machinery are among the demanding applications for which EN 10210 pipes made with HFW are frequently utilized. HFW pipes are suitable for projects requiring greater strength and dependability due to their improved mechanical properties and weld quality. However, the total cost of pipe production can be affected by the complexity and cost of HFW equipment, which typically costs more than standard ERW machinery.

LSAW(Longitudinally Submerged Arc Welding):

Longitudinal submerged arc welding (LSAW) is the welding technique utilized when fabricating EN10210 Pipe with large diameters and thick walls. The technique utilizes lowered bend welding to change the longitudinal crease of the steel plate into a round and hollow shape. A layer of granular flux helps to form the weld, which shields the molten metal from pollution in the surrounding air.

When making EN 10210 pipes, LSAW has many advantages. Pipes with thick walls and large diameters—often exceeding 16 inches—that were previously difficult to manufacture using ERW or HFW methods can now be produced using this method. The high penetration and deposition rate of submerged arc welding technology can result in a dependable and long-lasting weld. LSAW tubes typically have excellent mechanical properties and can withstand high internal pressures.

Major pipeline projects, offshore platforms, and heavy industrial applications frequently require EN 10210 LSAW pipes. Due to their capacity to produce pipes with thick walls, LSAW pipes are suitable for environments with high pressures and temperatures. In contrast, LSAW can increase production costs because it takes longer and requires more advanced equipment than ERW or HFW.

DSAW(Double Submerged Arc Welding):

When making EN 10210 pipes with a large diameter and a thick wall, the welding method known as longitudinal submerged arc welding (LSAW) is used. In this technique, the longitudinal crease of the steel plate is welded into a chamber by lowered bend welding. Under a layer of granular flux, which helps to form the weld and shields the molten metal from pollution, the weld is formed.

When producing EN 10210 pipes, LSAW has numerous advantages. The ERW or HFW method used to be difficult to manufacture pipes, but it is now capable of producing pipes with thick walls and large diameters, typically exceeding 16 inches. The weld is long-lasting and dependable due to the deep penetration and high deposition rate of submerged arc welding. The mechanical properties of LSAW tubes are typically excellent, and they can withstand high internal pressures.

For major pipeline projects, offshore platforms, and heavy industrial applications, EN 10210 pipes made by LSAW are frequently required. Due to their capacity to produce pipes with thick walls, LSAW pipes are suitable for environments with high pressures and temperatures. In contrast, the LSAW method takes longer and requires more sophisticated equipment than ERW or HFW, which can raise production costs.

SSAW(Spirally Submerged Arc Welding):

An innovative method for making EN10210 Pipe with large diameters is Spirally Submerged Arc Welding (SSAW). Submerged arc welding is used to weld the spiral seam of a continuous steel strip that is helically wound into a pipe. On both the inside and outside of the pipe, the majority of the time, the welding is done simultaneously.

SSAW has a number of advantages when it comes to making pipes that meet EN 10210 standards. This method permits the efficient utilization of steel coils and reduces material waste in comparison to plate-based methods. The ability of SSAW to produce pipes in a variety of diameters and wall thicknesses makes flexible manufacturing possible. The spiral weld pattern has the potential to also boost the pipe's strength in certain circumstances.

EN 10210 SSAW pipes are utilized in water transmission pipelines, piling applications, and some structural projects. Due to its low cost, the SSAW procedure is appealing for large-scale infrastructure projects. When compared to LSAW or DSAW pipes, SSAW pipes may have limitations in high-pressure or critical applications due to the nature of the spiral weld seam.
