lsaw steel pipe-Brief Description and Comparisons of LSAW, SSAW, and ERW Pipes-lsaw steel pipe
High quality steel pipes are produced from three (3) manufacturing processes: Seamless, LSAW (longitudinal-seam submerged arc welding), and ERW (electric resistance welding). LSAW and ERW pipes are highly regarded for their numerous fields of application. They are tremendously used in foundation solutions and systems, marine construction, structural construction, and diverse applications in water projects, petrochemical, chemical, and power industry, agricultural irrigation, urban construction, and more.En savoir plus -
LSAW Steel Pipe (Longitudinally Submerged Arc Welding Pipe) , DSAW Steel Pipe
LSAW steel pipe (Longitudinally Submerged Arc Welding abbreviated as LSAW) is a professional expression term for LSAW steel pipe. It uses a single medium and thick plate as the raw material, and the steel plate is pressed (rolled) into a tube blank in a mold or a forming machine. The pipe is produced by submerged arc welding and expanded diameter.UOE LSAW pipe forming process:The three main forming processes of UOE LSAW steel pipe forming process include: steel plate pre-bending, U forming and O forming. Each process adopts a dedicated forming press to complete the three processes of pre-bending the edge of the steel plate, U forming and O forming in sequence to deform the steel plate into a circular tube.JCOE LSAW pipe forming process:Forming: After several steps of stamping on the JCO forming machine, first half of the steel plate is pressed into a "J" shape, then the other half of the steel plate is pressed into a "J" to form a "C" shape, and finally pressurized from the middle to form An open "O"-shaped tube blank is formed.En savoir plus -
What is LSAW and SSAW Pipe?-lsaw steel pipe-erw pipe
LSAW and SSAW are variants of SAW (submerged arc welded) pipes. The difference between them is the way they are welded. In LSAW pipes, the welding is longitudinal, which means that steel (hot rolled coil plate) is rolled into a pipe and the seam is welded longitudinally. In the SSAW type, steel coils are welded spirally, like a helix, so that the coil (strip) assumes the shape of a pipe. SAW pipes are used mainly in oil and gas transportation. On the other hand, seamless (non-welded) pipes are mainly application in oil and gas exploration projects.An LSAW pipe (“submerged arc welding”) is manufactured by cutting, bending, and welding steel plates (JCOE process). The two main types of LSAW pipes are the longitudinal (with a single or double straight seam weld, DSAW) and the spiral type (called, HSAW, SSAW or SAWL pipe).En savoir plus -
LSAW Welded Steel Pipe: Features and Manufacturing Processes-lsaw steel pipe
LSAW (Longitudinal double submerge arc welding) carbon steel pipe is a type of SAW pipe made of steel plates that were hot rolled by JCOE or UOE forming technology. JCOE technology represents the shaping and forming processes involved during manufacturing as well as the inner and outer welding and cold expansion carried out after welding.When compared to UOE LSAW steel pipes, LSAW pipe manufacturers in China can produce more sizes as thus: OD 406 mm – 1620 mm, thickness 6.35 mm – 60 mm, pipe length 2 m – 18 m with the LSAW pipe having superiority.Octal offers LSAW steel pipe with high quality and competitive prices.En savoir plus -

Longitudinally Submerged Arc Welding pipe(abbreviated as LSAW pipe). The Longitudinally Submerged Arc Welding (LSAW) is produced by using a single plate as a raw material, pressing (rolling) the steel plate into a pipe blank in a mold or a molding machine, and adopting double-sided submerged arc welding and expanding the diameter. The finished product has a wide range of specifications, and the weld has good toughness, plasticity, uniformity and compactness, and has the advantages of large pipe diameter, thick pipe wall, high pressure resistance, low temperature resistance and corrosion resistance.En savoir plus -

Longitudinal Submerged Arc Welding (LSAW) Processes-lsaw steel pipe-Stainless steel pipe
Steel pipes are long, hollow tubes that are used mainly to convey products from one location to another. They are produced mainly by two distinct manufacturing methods which result in either a welded pipe or seamless pipe. In both the manufacturing methods, raw steel is first cast into a more workable starting form (slabs, hot billet or flat strip). It is then made into a pipe by stretching the hot steel slab/billet out into a seamless pipe or forcing the edges of flat steel strip together and sealing them with a weld.En savoir plus
