If you are manufacturing or needing welded pipes for use in metallurgy, construction, transportation, machinery and vehicle
In addition, the high-frequency welded pipe unit has a higher linear speed, and the buried The speed of arc welded pipe is generally 3m/min, which does not match each other. Therefore, the high-frequency welded pipe unit needs to fully utilize and expand its advantages in order to improve product quality and develop new products.
MICROSTRUCTURAL CHANGES IN THE FORGE WELD High-frequency electric resistance welding is one of the most common process for production of longitudinal seam welded carbon steel pipes suitable for line pipe, casing and tubing. In this pipe production process, the hot rolled strip goes into the forming mill
Production Standard of High Frequency Straight Seam Welded 4. ERW casing adopts hot-rolled coiled sheet, the grain size and microstructure density of the tubeblank are higher than that of seamless tube. 5. In terms of price, ERW steel pipes are also quite competitive and have a long service life. Specification of high frequency straight seam welded pipe:Out Diameter:1/2"-24" Wall Thickness:1.65-20mm
High-frequency longitudinally welded pipe production line is mainly used for the production of welded steel pipe of 8 ~ 610 mm and wall thickness of 0.5~ 20mm as well as the production of square, rectangular, and other custom seamless pipe profile, Carbon steel pipe, ERW steel Tube.
Welded Standard & Line Pipe US Steel Tubular ProductsERW standard pipe and high frequency electric-welded line pipe are widely used throughout the oil and gas industry, as well as for pipe piling and cable pipe systems. With over a century of producing steel products for the energy business, U. S. Steel Tubular Products offers a variety of manufacturing methods to produce steel pipe that can meet
Welded vs. seamless steel pipe American Piping ProductsWelded vs. seamless steel pipe. As industrial applications have evolved and grown more complex, the piping products and systems that serve them have had to keep pace. While many pipe manufacturing methods exist, the most prominent discussion in the industry compares electric resistance welded (ERW) vs. seamless (SMLS) steel pipe.
Electric Resistance Welded (ERW) and High Frequency Induction (HFI) Welded Pipe, originally this type of pipe, which contains a solid phase butt weld, was produced using resistance heating to make the longitudinal weld (ERW). But most pipe mills now use high frequency induction heating (HFI) for better control and consistency.
High-frequency electric resistance welding:An overview
- Why HF Erw?Welded Beam CustomizationHF Erw Enables Lean ManufacturingApplicationsWeld Quality.Solid-state, high-frequency welding for ESS in general requires minimal heat input, produces a narrow heat-affected zone (HAZ), and results in improved weld properties. The solid-state weld process uses less heat input because high-frequency (150-400 kHz) electromagnetic energy is used in conjunction with high pressure to join two materials. The material isjoined under heat and pressure instead of melted together with a filler material. Controlling key welding process parameters, such as fr
