API 5L Grabc, X52-X80, P5 P9 P11 P12, T11 T12 T91 Oilfield Pipeline SSAW Steel Pipe
Brief overview: SSAW steel pipe ( Spiral Submerged- Arc Welded Steel Pipe ) is also known as the SAWH
Steel pipe(Submerged-arc Welded Helical pipe )
Generally used: welded pipes convey fluid, metal structures, pile and so on. Our products are widely used in
water engineering, petrochemical industry, chemical industry, power industry, agricultural irigation, urban
construction, and spiral submerged steel pipe is one of 20 key products of development. For the transport of
liquids: water supply, drainage. For. gas transportation: gas, steam, liquefied petroleum gas. For structural
purposes: as piling pipe, for bridges; piers, roads, buildings and other structures tube.
The SAWH steel pipe is the spiral submerged arc welding steel pipe for short. It is made adopting sumberged
arc welding technique and comes with a welding seam.
Threeway steel has overwhelming advantages over cometiotors in manufacturing this SAWH steel pipe.We
have.10 traditional one-step production lines and 1 two-step production line that enabels to produce finely
pre-welded SAWH steel pipe of 360000 tons per year,and we have become the leading enterprise in this
industry in virtue of large productivity and advanced technical equipment.
