steel pipe

 Spiral steel pipes and seamless steel pipes are relatively common pipes in life, and they are used in house decoration and construction. So what is the difference between spiral steel pipes and seamless steel pipes? What is a spiral steel pipe? Spiral steel pipe (SSAW) is a spiral seam steel pipe made of strip steel coil as raw material, extruded at regular temperature, and welded by automatic double-wire double-sided submerged arc welding process. The spiral steel pipe sends the strip steel into the welded pipe unit, and after rolling by multiple rollers, the strip steel is gradually rolled up to form a round tube billet with an opening gap. Adjust the reduction of the extrusion roller to control the weld gap at 1~ 3mm, and make both ends of the welding port flush. The appearance of the spiral pipe has spiral welding ribs, which is caused by its processing technology. What is seamless steel pipe? Seamless steel pipe (SMLS) is a long strip of steel with a hollow section and no sea...

Spiral pipe is made by rolling low-carbon carbon structural steel or low alloy structural steel strip into a tube blank according to a certain helical angle (called forming angle), and then welding the pipe seam. It can be made with a narrower strip Steel produces large diameter steel pipes. Its specifications are expressed by outer diameter * wall thickness. The welded pipe should ensure that the hydraulic test, the tensile strength of the weld and the cold bending performance must meet the regulations. Inspection process: Raw material inspection—leveling inspection—butt welding inspection—formation inspection—inner welding inspection—outer welding inspection—pipe cutting inspection—ultrasonic inspection—groove inspection—outline dimension inspection—X-ray inspection --Hydraulic test --Final inspection In order to guarantee the products, we have formulated a comprehensive plan, on-site work procedures and inspection and test plans.

The customer is a local stocker and also participates in the supply of products for oil projects. Through the cooperation in 2021, Xinyue has won the recognition and favor of customers. Since then, the two sides have started close contact, and Xinyue’s business specialists have never failed to meet customers’ expectations, and have consistently provided various steel consulting services for customers. In June last year, the customer sent a product inquiry. All the steel involved were our superior products, ERW welded pipe and galvanized pipe. In combination with the various needs of customers, our company submitted the price and scheme...

Project location：Ecuador Product：SSAW Tubular Piles Standard and material：API 5L X65 Specifications：914mm x 22mm x 40.95–47.1m Application：Port Construction Inquiry time：2021.02.07 Order time：2022.08.03 Shipping time：2023.01.08 Estimated arrival time：2023.2.18 After two years of dedication and effort, Xinyue successfully completed the supply of pipe piles for the construction of Ecuador’s port, laying a solid foundation for Xinyue’s long pile export. During the operation of the whole contract, all team members brought the spirit of “dedication and cooperation, pioneering and enterprising”, which made the editor also follow with high morale. Next, let the me talk about it. Customers often ask, “Can Xinyue surely produce 45 meters of steel pipes? The factory is neither near the sea nor near the river. In this condition, can we really ensure that there is no problem with the internal transportation?” The answer is double affirmation. Xinyue has been committed to the export of long piles f...
