Electric Resistance Welded (ERW) steel pipe is one of the most widely used welded tubular products across global construction, municipal engineering and industrial sectors. Also known as high-frequency resistance welded pipe, it stands out for its stable performance, competitive price and reliable quality.
ERW pipe is manufactured by rolling steel strips into a tubular shape and joining the edges via high-frequency electric resistance welding. This production process creates a solid, uniform weld seam, ensuring excellent roundness and consistent wall thickness. Most ERW pipes are produced in accordance with ASTM A53, the mainstream standard for carbon steel welded pipes.
There are obvious advantages of ERW steel pipe. First of all, it is more economical than seamless steel pipe, making it the preferred option for large-scale ordinary piping projects. Secondly, the tight weld joint provides good pressure resistance and structural stability for daily fluid transportation. Besides, it comes with a complete range of sizes, wall thicknesses and pipe ends, including plain end, bevel end and threaded end, to fit diverse installation requirements.
This type of pipe serves a broad range of applications. It is commonly applied to water supply and drainage pipelines, natural gas delivery systems, building frameworks, fire protection piping and outdoor structural projects. Whether for residential buildings, municipal works or general industrial pipelines, ERW pipe delivers long-lasting service.
All our ERW steel pipes undergo strict inspections, including hydrostatic testing, dimensional check and appearance inspection before delivery. If you are looking for affordable, durable and standard-compliant welded steel pipes for your projects, ERW pipe will be your ideal solution.
