ERW steel pipe is a kind of steel pipe which is welded together under pressure by making the contact part generate resistance heat through high frequency current. This welding process does not require the addition of any welding filler material, so it is also known as high-frequency welded pipe or contact welded pipe.
IBC Group offers a wide range of ERW pipes types and specifications, including products of different materials, wall thicknesses and lengths. This diversity allows customers to choose the right steel pipe according to their needs, increasing the flexibility of procurement.
In addition, we have an extensive sales network and strong logistics distribution capabilities, which can quickly respond to customer needs and ensure that products are delivered on time. This provides customers with a convenient purchasing experience, saving time and effort.
