As a  Black Coating SSAW Steel Pipe Supplier , share with you. SSAW Steel Pipe  refers to the metal pipe with spiral seam welded by submerged arc welding. It is possible to produce a welded pipe with a larger diameter from a narrower billet, and it is also possible to produce a welded pipe with a different diameter from a billet of the same width. The production cost is low, and the spiral seam submerged arc welded steel pipe with simple anti-corrosion treatment is easy to produce large-caliber pipes. Production Process: SSAW Steel Pipe Spiral steel pipe is a spiral seam steel pipe with strip steel coil as the raw material, often warm-extruded, and welded by an automatic double-wire double-sided submerged arc welding process. (1) The raw materials are strip coil, welding wire, and flux. Before going through the strict physical and chemical tests. (2) Strip steel head-to-tail butt joint, single wire or double wire submerged arc welding, automatic submerged arc ...

ERW Steel Pipe Supplier  introduces the methods to prevent ERW steel pipe from breaking, and everyone can refer to it. ERW steel pipe manufacturers usually improve its performance by adding alloys to the material. After cold drawing, stress annealing is required to eliminate the residual stress of the material to prevent the ERW steel pipe from breaking. At present, China's ERW steel pipe manufacturers improve metal strength through cold drawing, but it comes at the expense of metal shaping and toughness. Cold drawn ERW steel pipe is based on the market with high dimensional accuracy and high strength performance. It must ensure that the amount of deformation is within a certain range in order to maximize the performance of the material and reduce the adverse impact on the material. ERW Steel Pipe If the deformation of the ERW steel pipe is small, it can not meet the requirements of smoothness and dimensional accuracy, nor the strength of the component. If the deformatio...

As an  ERW Carbon Steel Welded Pipe Supplier , I will tell you to choose the right venue and warehouse first: ERW Carbon Steel Welded Pipe (1) The site or warehouse where the  ERW Carbon Steel Welded Pipe  is kept should be selected in a clean, well-drained place away from factories and mines that produce harmful gases or dust. Remove weeds and all debris on the site and keep steel pipes clean (2) Do not stack in the warehouse with materials that are corrosive to steel pipes such as acids, alkalis, salts, and cement. Different types of steel pipes should be stacked separately to prevent confusion and prevent contact corrosion (3) Large sections, rails, steel plates, large-diameter steel pipes, forgings, etc. can be stacked in the open air (4) Small and medium-sized steel, wire rods, steel bars, medium-caliber steel pipes, steel wires and wire ropes, etc. can be stored in well-ventilated sheds, but they must be underlay (5) Some small steel pipes, thin steel...

" ERW Steel Pipe " is Electric Resistance Welding, abbreviated as ERW. It is used to transport vapor and liquid objects such as oil and natural gas. It can meet various requirements of high and low pressure. It currently plays a pivotal role in the field of transmission pipes in the world. 1. Welded pipes are round pipes made of steel plates, divided into high-frequency resistance welded pipes (ERW welded pipes), straight seam welded pipes (LSAW), and spiral welded pipes. 2. The line pipe is also a wire tube, which is relatively thin. It is indicated by "T" and can only be used as a pipe. 3. The ERW pipe is a "high-frequency resistance welded steel pipe", which is different from the ordinary welding pipe welding process. The welding seam is made by melting the base metal of the steel strip body, and the mechanical strength is better than that of the ordinary welded pipe.

As a  Seamless Steel Pipe Supplier , share with you. 1. Hot rolling (extruded seamless steel pipe): round pipe billet → heating → perforation → three-roll oblique rolling, continuous rolling or extrusion → stripping → sizing (or reducing) → cooling → straightening → hydraulic test (Or flaw detection) → mark → storage The raw material for rolling the  Seamless Steel Pipe  is a round tube blank. The round tube blank is cut into a billet with a length of about 1 meter by a cutting machine and sent to a furnace for heating by a conveyor belt. The billets are sent to a furnace for heating to a temperature of about 1200 degrees Celsius. The fuel is hydrogen or acetylene. Furnace temperature control is a key issue. After the round tube billet is discharged, it is pierced through a pressure perforator. Generally, the more common punching machine is a tapered roller punching machine. This punching machine has high production efficiency, good product quality, large perforation...

Seamless Steel Pipe  can be made from any of several alloys and metals, such as carbon steel, stainless steel, molybdenum or tungsten. 1. The difference between the seamless steel pipe and welded pipe: seamless steel pipe is extruded and stretched from the blank, while the welded pipe is made of steel strip rolled and welded to produce pipe. Because seamless steel pipes provide a higher range of safety measures, they are more expensive than welded pipes. The length of seamless steel pipes is relatively short, while welded pipes can be manufactured in long continuous lengths. Unless subject to a highly corrosive environment, seamless steel pipes generally do not show any signs of corrosion and welded areas in welded pipes are more susceptible to corrosion. The welded area is considered to be non-uniform, so it exhibits different ductility and less corrosion resistance as well as larger dimensional changes. Seamless steel tubes eliminate any such problems and are therefo...
