The high frequency straight seam steel pipe(eg:ERW steel pipe) is based on the principle of electromagnetic induction and the skin effect, proximity effect and eddy current heating effect of the AC charge in the conductor, so that the steel at the edge of the weld is locally heated to a molten state, and the butt weld is realized by the extrusion of the roller Intercrystalline bonding, so as to achieve the purpose of welding seam welding.

High-frequency welding is a kind of induction welding (or pressure contact welding). It does not require weld fillers, no welding spatter, narrow welding heat-affected zone, beautiful welding shape, good welding mechanical performance and other advantages. Therefore, it is very popular in the production of steel pipes. Wide range of applications.

The high-frequency welding of steel pipes uses the skin effect and proximity effect of alternating current. After the steel (strip) is rolled and formed, a circular tube blank with a broken section is formed, which is rotated around the middle of the induction coil in the tube blank. Or a set of resistors (magnetic rods), which form an electromagnetic induction loop with the opening of the tube blank. Under the action of the skin effect and the proximity effect, the edge of the opening of the tube blank generates a strong and concentrated heat effect, which makes the weld edge After being quickly heated to the temperature required for welding and squeezed by the pressure roller, the molten metal realizes intergranular bonding, and after cooling, a firm butt weld is formed.

Introduction

Steel pipes are an essential component of various industries, from construction to transportation. They come in different shapes and sizes, but one type that stands out is the straight seam steel pipe. This type of pipe has gained popularity due to its efficient manufacturing process and remarkable strength. In this blog post, we'll delve into the manufacturing process of high frequency straight seam steel pipe and explore why it's a top choice for many industries. So buckle up and let's dive in!

The manufacturing process of high frequency straight seam steel pipe

The manufacturing process of high frequency straight seam steel pipe involves several steps that ensure the production of a quality product. The first step is the selection of raw materials, which are usually hot-rolled coils or sheets. These materials are then fed into a machine called the uncoiler, which removes any rust or dirt from their surface.

After this, the material passes through a series of rollers that shape it into a cylindrical form. This cylinder is then passed through an electric welder where high-frequency current is applied to fuse its edges together and create a continuous seam along its length.

The welded tube then goes through various sizing processes until it reaches its final dimensions. These include forming, sizing, and cooling processes that help to ensure that each tube meets precise specifications for diameter and wall thickness.

After passing quality control checks for defects such as cracks or other imperfections in the welds, these tubes are cut to length before being shipped out for use in construction projects ranging from pipelines to structural supports.

Producing high-quality straight seam steel pipes requires careful attention at every stage of manufacturing – from selecting raw materials all the way through final inspection – but when done correctly results in products with exceptional strength and durability properties essential across many industries.

The advantages of high frequency straight seam steel pipe

The advantages of high frequency straight seam steel pipe are numerous and make it an excellent choice for a wide range of applications. Firstly, these pipes have a strong resistance to corrosion which makes them suitable for use in harsh environments. This feature ensures the longevity of the pipeline.

Secondly, they are highly durable and can withstand high pressure and temperature fluctuations without sustaining any damage. For this reason, they are widely used in industries such as oil and gas transportation, construction projects, water supply systems among others.

Thirdly, their manufacturing process is simple yet efficient. The use of high-frequency electric currents during production ensures that the resulting product has consistent dimensions throughout its length.

Fourthly, these pipes require minimal maintenance due to their superior strength properties which reduce leakages over time compared to other types of pipelines.

High frequency straight seam steel pipes also offer cost savings since they require fewer materials during installation than other types of pipelines while still providing excellent performance capabilities.

Conclusion

To sum up, the manufacturing process of high frequency straight seam steel pipe involves several steps that ensure its durability and reliability. The use of advanced technology and methods in production makes it possible to create pipes with excellent resistance to corrosion, pressure, and temperature.

Moreover, the advantages offered by high frequency straight seam steel pipes make them highly sought after in various industries such as oil and gas exploration, construction, water supply systems, and many others.

If you are looking for a reliable material for your project needs that can withstand harsh environments while maintaining structural integrity over time - look no further than high frequency straight seam steel pipe. This piping solution is an excellent choice for anyone who wants to ensure their infrastructure stays strong and secure against any challenges it may face.
