A36 A53 A106 LSAW Sawl ERW Large Diameter Sch 40 Alloy A252 Q235B Spiral Welded Steel Carbon Steel Pipe

Product DescriptionSpiral welded pipe.Compared with the straight seam welded pipe, the spiral welded pipe has higher strength and larger diameter. The production standard of the spiral welded pipe is more than that of the straight seam welded pipe. Mainly used in steel structure engineering, machinery manufacturing, construction water, oil pipelines and other low-pressure fluid pipelines, and can also be used in piling,structure and other construction fields.  Product Name A36 A53 A106 LSAW Sawl ERW Large Diameter Sch 40 Alloy a252 q235b spiral welded steel carbon steel pipeStandardAPI5L, ASTM A106 Gr.B, ASTM A53 Gr.B, ASTM A270, ASTM A249, ASTM A511,ASTM A778 ,ASTM A312,ASTM A358,ASTM A409,ASTM A213,ASTMA790,ASTM A268,ASTM A269,ASTM A554,ASTM B338,ASTM B673,ASTM B674,ASTM B677,ASTM B675, ASTM B676, ASTM B690,ASTM A928,ASMEB36.19,ASMEB36.10,ASTMA179/A192/A213/A210/370WP91,WP11,WP2GB5310-2009,GB3087-2008,GB6479-2013,GB9948-2013,GB/T8163-2008, GB8162-2008,GB/T17396-2009EN10216-5,EN10217-7,DIN 17456,DIN 17458JIS G3463,JIS G3119,JIS G3446,JIS G3218,JIS G3258,JIS G3448,JIS H4631DEP 31,DEP 40,DEP 20,DEP 32,DNV-OS-F101GradeQ195 = S195 / A53 Grade AQ235 = S235 / A53 Grade B / A500 Grade A / STK400 / SS400 / ST42.2Q345 = S355JR / A500 Grade B Grade COuter DiameterERW / HFWLSAW / DSAWSSAW / HSAWRHSSHS1/8 - 20 inch12 - 56 inch8 - 126 inch40 x 20 mm15 x 15 mm(10.3-508 mm)(323.8-1,420 mm)(219.1-3,200 mm)-1,000 x 800 mm-1,000× 1,000 mmWall Thickness0.4 - 16 mm6.0 - 40 mm6.0 - 26 mm1.0 - 30 mm0.6 - 30 mmLength5.8~12.0 m or as customizedSurface TreatmentPrime quality (bared, oiled, color paint, 3LPE, or other anti-corrosive treatment)InspectionWith Chemical Composition and Mechanical Properties Analysis;Dimensional and Visual Inspection, also with Nondestructive Inspection.Packaging & Shipping 1. Package with 20 ft or 40 ft container, fixing spiral steel pipe in the container with steel cable;2. Package in bulk;3. Pieces per container depending on the diameter of spiral steel pipes.4.According to customers' requirement.Advantages of spiral welded pipe. (1) Steel pipes of different diameters can be produced using strip steel of the same width, and steel pipes of large diameter can be produced from narrow strip steel.(2) Under the same pressure conditions, the stress of the spiral welded seam is smaler than that of the straight seam, which is 75% to 90% of that of the straight seam welded pipe, so t can withstand greaterpressure. Compared with the straight seam welded pipe of the same uter diameter, the wal thickness can be reduced by 10% to 25% under the same pressure3) The size is accurate. the oenera diameter tolerance does not exceed 0.12%,.the delection is ess than 12000. and the ovalitv is less than 1% Generally, the sizing and straightening process can be omitted.(4) Continuous production is possible. ln theory, long steel pipes can be produced. with small head and tail loss. and canincrease the metal utilization rate by 6% to 8%. (5) The eouipment is ioht in weioht and ow initial investment. t can be made into a trailer-ype mobie unit to directly produce welded pipes at the construction site where the pipeline is laid. The production of spiral welded steel pipes can reflect the advantages of high quality and high efficiency. The production capacity of one spiral welded pipe unit is equivalent to 5-8 sets of straight seam welded pipe equipment. How to make multiple pipe coiling equipment production lines meet the same production standard, that is, produce according to a unified production process specification and quality assurance system to meet welding quality Requirements and piping manufacturing grades will be an arduous task.Guangdong Steel Bull Import and Export Co., Ltd. in July2023 ,the sixth branch of Jinan Jinhongtong Steel Pipe Co. , Ltd our company is well-funded,can support large orders.     At the same time with Baosteel, Laiwu Iron and Steel, Rizhao Iron and steel, Handan Iron and steel, Anyang Iron and steel, Maanshan Iron and steel and other large domestic steel enterprises to establish strategic partnership.Our annual sales nearly three billions,about 600,000 tons steel.Also have ourselves steel process factory with 100000 Square meter for steel laser cutting,surface treatment and other further processing,and our stock always more than 20,000 tons.Mainly engaged in:PPGI,galvanized steel,steel plate,round bar,steel pipe,stainless steel product,angle bar,steel pile ,H beam,I beam,angle,Channel flat steel etc.A variety of products to ensure a variety of customer needs.FAQQ1: How many countries you already exported?A1: Exported to more than 50 countries, mainly from Bangladesh, Indonesia,Philippines, Serbia, Brazil, Iraq, Israel, United Arab Emirates, etc.Q2: How long will it take to execute my order?A2: Delivery time of stock products: 3-7 days after payment.
