How do ERW Pipes differ from HRF Steel pipes?

ERW and HFW have welding processes: The term "ERW welding process" refers to the heat produced due to the resistance formed during the passing of current through the connecting metal during the welding process. Because of this, a substantial amount of current is necessary to charge the steel plate’s whole surface area to the welding length. The frequency of the 50/60 Hz current that runs through the whole conductor is maintained throughout the ERW welding process.

The high-frequency electromagnetic welding process differs from the HFW welding process because just a portion of the metal is heated by the induction coil during the highfrequency electromagnetic welding process. High frequencies can be generated by both direct current and alternating current circuits. In situations like these, a constant current welding generator, as well as a high-frequency welding generator working at constant voltage, are utilised.

A welding machine at Tube Trading Co., one of the most reputed MSERW pipe distributors in Gujarat, uses constant current and is capable of producing power at

frequencies ranging from 100 to 800 kHz. In an early stage of the process, a tank circuit and a triode were utilised to transform the 60 Hz AC current into HF. This novel welding machine makes use of metal oxide silicon field effect transistors, which are often seen in parallel resonant circuits. Isolated gate bipolar transistors are utilised in the constant voltage generator construction. This transistor has a frequency range of 100-600 kHz and a design power of approximately 2000 kW. Its frequency range.

The most distinguished MSERW pipe dealer in Gujarat - Tube Trading Co., has listed two characteristics that differentiate HF current from line current that operates at 60 Hz: ● The current at the line frequency of 60 Hz flows through the entire conductor, whereas the current at high frequency (HF) flows just on the conductor’s surface; this phenomenon is known as the "skin effect." ● The "proximity effect" is the phenomenon that occurs when two conductors that are carrying HF current are put close to one another. This causes the current to concentrate on the conductor’s adjacent surfaces.

The HFW current distribution has the current flowing on the surface of the conductor or metal. Both conductors are positioned quite close to one another, and most of the HF current flows along the sides of the adjacent conductors. If you are looking for the most prominent as well as distinct MSERW pipe provider in Gujarat, Tube Trading Co. is the best pick for you.

Features of ERW pipe: ● Low cost: Because of the low cost of both the raw materials and the manufacturing process, its costs are more competitive than those of seamless pipes as well as submergedarc welded pipes having a longitudinal seam.

● High Weld Seam Security: Because of the unique welding technique that involves melting the parent metals together without using any filler metal, the welding property is superior to that of submerged-arc welded pipes; the seam security is significantly improved, and the weld seam is significantly shorter than that of spiral seam welded pipes.

● Wide Range: ERW pipes are capable of being utilised with an extensive variety of thickness-todiameter ratios, encompassing hundreds of different requirements. Tube Trading

Co. is an excellent MSERW pipe supplier in Gujarat who can fulfil all of your Stainless Steel pipes and tubes requirements.

ERW steel pipe includes HFW steel pipe: The acronym ERW refers to a steel pipe that has been welded using electric resistance.

DC welding and AC welding are the two categories that may be broken down into (DC).

Low-frequency, intermediate-frequency, high-frequency, and extreme high-frequency welding are the subtypes of alternating current (AC) welding that can be distinguished by the frequency at which the current is flowing. The high-frequency welding (HFW) process is typically applied to steel pipes with standard or thin-walled walls. It encompasses induction welding in addition to contact welding. DC welding is typically utilised for steel pipes with a smaller diameter. High-frequency welding, or HFW for short, is one of the various ERW production processes that makes use of high-frequency welding technology. As a consequence of this, the HFW steel pipe is included in the ERW steel pipe.
