 Spiral pipe (SSAW) is a welded 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. How to increase the stability of spiral steel pipe 1) Small and medium-sized steel bars, wire rods, steel bars, medium-caliber steel pipes, steel wires, and wire ropes can be stored in well-ventilated sheds, but they must be covered with thatch. 2) Some small steel products, thin steel plates, steel strips, silicon steel sheets, small-diameter or thin-walled steel pipes, various cold-rolled and cold-drawn steel products, and high-priced and corrosive metal products can be stored in the warehouse. 3) The site or warehouse for storing spiral steel pipe products should be selected in a clean and well-drained place, away from factories and mines that produce harmful gases or dust. Weeds and all debris should be removed on the site to keep the steel clean. 4) Large steel sections, rails, steel plat...

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 seams ar...

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.

 Xinyue’s Circular hollow sections (CHS) are a popular type of steel section used in construction projects. They are also known as round hollow sections, or simply as tubes. CHS have a circular cross-section and are commonly used in a range of applications due to their strength, versatility, and aesthetic appeal. One of the main advantages of Xinyue’s CHS is their structural strength. Due to the circular shape, they are able to withstand external forces and support heavy loads without buckling or collapsing. This makes them ideal for use in structural applications such as columns, beams, and trusses. In addition to their strength, Xinyue’s CHS are also highly versatile. They can be easily cut, bent, and welded to suit a range of construction needs. They are commonly used in the construction of bridges, buildings, and other structures where strength and durability are key requirements. Another benefit of Xinyue’s CHS is their aesthetic appeal. Their smooth and rounded shape gives th...

 Common surface defects of welded steel pipe: (1) layered steel Layered wall steel tube means the cross section is divided into two floors, exposed steel surface showing the hierarchical vertical cracks. Some exhibits inside and outside surfaces of steel recessed or raised locally, layered rendering suddenly raised, dents or warping in and out of the weld. (2) sticky scar Pipe sticky scar refers to internal and external surfaces of the massive steel focal adhesion plaques scar. (3) holes Pipe through the hole refers to a local steel tube bi holes exist. (4) open welding Welded steel pipe opening means through long cracks in steel welds or partial showing of. (5) Local lap welding Welded steel pipe refers to a partial outer surface of the steel pipe presents a partial arc weld. (6) Welding ditch Pipe welding groove is the outer surface of the steel pipe occurs through a long groove weld. (7) the collapse of welding Welded steel pipe collapse refers to the outer surface of the weld m...
