SSAW Steel Welded Spiral Steel Pipe Double Sided Arc Submerged Steel Welded Tube Q235 Q345 Spiral Steel Pipe Carbon Steel With Plastic Pipe Cap Or Iron Protector Hot Galvanized Seamless / ERW Carbon Steel Pipe , ASTM A252 ASTM A53 Low Pressure Tube
SSAW steel pipe is the raw material of strip coil, often temperature extrusion molding, automatic double-wire double submerged arc welding process made of spiral seam pipe. Spiral steel pipe will strip into the pipe unit, the multi-roll rolling, strip rolled up, forming a circular gap opening gap, adjust the squeeze roll reduction, the weld gap control in the 1 ~ 3mm, and make both ends of the weld flush.
LSAW Pipe (Longitudinal Submerged Arc-Welding Pipe), is taking the steel plate as raw material, mold it by the molding machine, then do double-sided submerged arc welding. Through this process the LSAW steel pipe will get excellent ductility, weld toughness, uniformity, plasticity and great sealing.
Spiral welded tubular pipes are produced from internally and externally welded steel coils. Piling pipes can be welded with pipe shoes to enhance drivability in difficult ground conditions. SSAW are often coated for use in ports, bulkheads and jettys.
SSAW Welded Steel Pipe Short Description: 1.The spiral steel: spiral steel coil as raw materials is steel, often warm extrusion, with automatic double- wire submerged arc welding process double- sided spiral welded steel pipe; 2.
General oil and gas long distance pipeline design specification for spiral submerged arc can only be used for 3 categories, 4 categories of regions.Welding of LSAW steel pipe: the longitudinal submerged arc welded pipe is in a single sheet of Zhonghou as raw materials, steel in mold or forming machine of medium voltage (volume), using double-sided submerged arc welding and expanding size and production.
Spiral steel pipe is a spiral seam steel pipe which is made of steel coiled coil as raw material, which is often heated and extruded, and welded by automatic double wire double-sided submerged arc welding process.
The influence of ssaw steel pipe production process factors on the quality of single-side welding double-sided forming welds mainly includes welding current, welding speed, number of welding layers, electrode type and electrode diameter.
Longitudinally Submerged Arc Welded Steel pipes LSAW (LSAW) in leaflets plate as raw material, the steel plate in the mold or molding machine pressure (volume) into using double-sided submerged arc welding and flaring from production.
Longitudinally Submerged Arc Welding (LSAW) pipes use single plate steel as raw material, applied double-sided submerged arc welding. The finished products have larger specifications and the welding joints have excellent ductility, plasticity and good sealing.
LSAW steel pipe has strong pressure bearing capacity and good plasticity, which is convenient for welding and processing. Generally, double-sided submerged arc welded pipe (SY5037-83) for low-pressure fluid transportation is made of water by double-sided automatic submerged arc welding or single-sided welding. Gas, air and steam.
Spiral Submerged Arc Welded Pipes. Spiral Submerged Arc Welded pipe, is a low-carbon structural steel or low-alloy structural steel strip according to a certain degree of helix angle (called forming angle) into a tube blank, and then by pipe seam welded together, It can produce large diameter steel pipe with narrower strip.
The spiral seam submerged arc welding steel pipe produced by our company is widely used in long bearing pipeline of oil, natural gas, heat, tap water and gas, etc. It can also be used in iron and steel, coal, chemical industry, electric power, irrigation, steel structure, pipe pile and other projects.
spiral welded steel pipe Our spiral steel pipe production lines are equipped with advanced automatic double-sided submerged arc welding apparatus which produce the high-quality pipes with high density and permeating defending weld seam.
Quality SSAW Steel Pipe manufacturers & exporter - buy Double - Sided SSAW Steel Pipe API 5L X56 Spiral Submerged Arc Welded Pipe from China manufacturer.
Large Welded Steel Pipe 3. 54inch*9.52Spiral steel pipe are producing 4. 36 inch Spiral Submerged-Arc Weld steel pipe (4) 5. 457mm OD LSAW steel pipe stuffed into Containers Tianjin Zhongshun Petroleum Steel Pipe Co.,Ltd. is a specalized manufacture of petroleum steel pipe, founded in 1995.It is located in the steel Base,Daqiuzhuang Town which , double side ssaw steel pipe spiral welded pipe
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). Therefore, the difference between DSAW vs. LSAW is that DSAW pipes have a seam weld in the inside and outside of the pipe, whereas LSAW pipes have a single seam weld on the outer surface.
Steel pipe, using the submerged arc-welding process (SAW), is manufactured by Hall Longmore to a diameter ranging from 660 mm to 2540 mm.
DSAW/SSAW SPIRAL STEEL PIPE DOUBLE SEAM WELDED PIPE Tianjin Xinyue Steel Group, located in Daqiuzhuang Industrial Area, Tianjin, China, is one of the most famous enterprise of steel pipe in China, since 1980. Consolidating steel pipe production, stocking, domestic & international marketing.
LSAW steel pipes is taking the steel plate as raw material, mold it by the molding machine, then do double-sided submerged arc welding. Through this process the LSAW steel pipe will get excellent ductility, weld toughness, uniformity, plasticity and great sealing.
Prime Steel Pipe is a leading manufacturer and exporter for SSAW steel pipe, welded steel pipe, spiral pipe, and spiral welded pipe.
Spiral Weld Pipe. Spiral Weld Pipe, as the name implies, is a steel pipe that has a seam running its entire length in a spiral form. In the past, due to the method of manufacture, Spiral Welded pipe was relegated to low pressure and structural applications. What is difference between seamless and welded pipe?
Differently SSAW pipe is spiral welded where the LSAW is longitudinally welded. Manufacturing process is rolling the steel strip, to make the rolling direction have an angle with the direction of the pipe center, forming and welding, sot he welding seam is in a spiral line.
The two sides of the double submerged arc weld penetrate the full thickness of the steel to ensure the strength of the finished pipe. Full scale tests have shown that high quality spiral welded pipe is as strong as API pipe. The strength and flexible manufacturing of spiral welded pipe make it the product of choice for a variety of applications.
Double Submerged Arc Welded (DSAW) steel pipe is available in straight and spiral welded formats and used in a variety of applications. The submerged welding process protects the steel from , double side ssaw steel pipe spiral welded pipe
ASTM A252-89 Weldedd and seamless pipe piles; Spiral Submerged-arc Welded steel pipe Success Stories; Internal and External Anti-corrosion steel pipe Standard; We are manufacturer of SSAW pipes and supply high quality SSAW pipes in both large and small quantities worldwide and offer you the best prices in the market.
SSAW steel pipe is a coiled steel pipe made from strip coils as the raw material, which is often warm extruded and welded by an automatic double wire double-sided submerged arc welding process. The strength of the ssaw steel pipe is generally higher than that of the lsaw steel pipe.
