Product Description

-The spiral submerged-arc welding pipe is produced by submerged  arc method which is based on tandem welding technique for joining inside and outside coil edges in order to gain high quality weld structure.

-It has strudy construction to support the pipe with stable and consistent operation. With strict requirements, as well as refined craftsmanship, it has good sealing to make sure it work with no leakage, which causes no damage to the nature and the human being.

-And it is odorless, and non-toxic, containing no harmful substances. It has smooth surface which allow the mass flow of liquids to pass through, greatly enhancing the working efficiency and providing the comfortable using experience.

-With the resistance to corruption, oxygen, water and dust, it is durable with long life circle that it can be used over and over again, which is quite cost effective.

-The spiral submerged-arc welding pipe is  widely used as the  conveyance and distribution pipelines of oil, natural gas, water and other flammable & nonflammable liquid, which can also be applied to steel structures for construction and  other general purposes.
