Application of #spiral steel pipe (#SSAW) in water pipeline engineering The water plant is an important part of the city and is responsible for providing clean and safe drinking water to residents. In this process, spiral steel pipes (SSAW) play a vital role. This kind of steel pipe has won the trust of water plants and residents with its excellent performance and long service life. Main application areas: 1. #Drinkingwater transportation: Spiral steel pipes are widely used in drinking water transportation pipelines to ensure the cleanliness and safety of water quality. 2. #Watertreatment equipment: Water treatment equipment in water plants requires the use of highly corrosion-resistant and high-strength spiral steel pipes to ensure stable operation of the equipment. 3. Building #watersupply and drainage: In the water supply and drainage systems of high-rise buildings and large public facilities, spiral steel pipes have excellent pressure resistance and corrosion resistance, making them an ideal choice for water supply and drainage pipes. Advantages of spiral steel pipe: 1. High strength: Spiral steel pipes are made of high-strength steel, which has excellent tensile and compressive properties and can withstand huge pressure and weight. 2. Corrosion resistance: Pipes in water plants often face highly corrosive environments, and spiral steel pipes have excellent corrosion resistance and can effectively prevent secondary pollution of water quality. 3. Long life: The design life of spiral steel pipes is up to 50 years, which can greatly reduce the maintenance costs and downtime of water plants. 4. Easy installation: The installation of spiral steel pipes is simple and fast, and does not require special tools and equipment, effectively shortening the construction period. #PMC provides high-quality spiral steel pipe products and services for water pipeline engineering.

#LSAW (Longitudinally #SubmergedArcWelding) steel pipes are produced by using a single medium-thick plate as raw material, pressing (rolling) the steel plate into a tube blank in a mold or forming machine, and enlarging the diameter using double-sided submerged arc welding. According to different #molding methods, it can be divided into: #UOE steel pipe: After the single steel plate is pre-bent at the edge, it undergoes processes such as U forming, O forming, internal welding, external welding, and mechanical cold expansion. #JCOE steel pipe: pre-welding, forming, cold expansion after welding and other processes according to "J-C-O-E" #HME steel pipe: formed by mandrel rolling method according to "C-C-O", welded and then cold expanded. The video below shows the #internal and #externalwelding of LSAW steel pipes in the production process. Main features of #LSAW steel pipe: (1) The steel pipe has a #longitudinalweld, and both the inner and outer welds are welded by one submerged arc welding. (2) After the overall mechanical diameter expansion treatment, the internal stress of the steel pipe is small and evenly distributed, which can effectively prevent stress corrosion cracking, has high dimensional accuracy and facilitates on-site welding construction. (3) Using the process of pre-welding and then precision welding, the welding process is stable and the weld quality is high. (4) Welds are easy to implement non-destructive testing during the production process and non-destructive testing review in the field during use. (5) The range of product specifications is large, and it can produce both small diameter and large wall thickness steel pipes and large diameter and large wall thickness steel pipes.

Large-diameter #straightseam steel pipes (such as #LSAW & #DSAW) are the best choice for large-scale pipeline projects, water and gas transmission projects, tap water projects, petrochemical industry, chemical industry, electric power industry, agricultural irrigation, and urban pipeline network construction. Before shipment, straight seam steel pipes should undergo mechanical performance tests, tensile tests, bending tests, flattening tests, guide bending tests and hydraulic tests, and must meet the requirements specified in the standards. The steel pipe should be able to withstand a certain internal pressure, and there should be no leakage in the steel pipe during the experiment. Electric resistance welded steel pipes are allowed to use ultrasonic flaw detection or eddy current flaw detection instead of hydraulic testing. Submerged arc welded steel pipes are allowed to have ultrasonic flaw detection or radiographic flaw detection instead of hydraulic testing. #PMC specializes in the production and supply of #large-diameter straight seam steel pipes, #thick-walled straight seam steel pipes and #double-sided submerged arc welded straight seam steel pipes (DSAW). Our equipment is complete and we can customize and process steel pipes of various materials according to customer needs.

ASTM A53 GR.B #SSAW steel pipe manufactured by PMC Size: 710MM*10MM*6M Advantages of SSAW steel pipe: (1) The use of steel strips of the same width enables the production of steel pipes of different diameters, in particular the production of large-diameter steel pipes with narrow strip steel. (2) Under the same pressure conditions, the spiral welds are subjected to a smaller stress than the straight seams, which is 75% to 90% of the straight seam welded pipes, and can therefore withstand greater pressures. Compared with the straight welded pipe with the same outer diameter, under the same pressure, the wall thickness can be reduced by 10% to 25%. (3) Accurate size, general diameter tolerance is not more than 0.12%, deflection is less than 1/2000, ellipticity is less than 1%, and sizing and straightening processes are generally omitted. (4) It can be continuously produced. In theory, it can produce infinitely long steel pipes, and the loss of cutting and cutting tails is small, which can increase the metal utilization rate by 6% to 8%. (5) Compared with the straight seam welded pipe, its operation is flexible and the adjustment of the replacement type is convenient. (6) The equipment is light and the initial investment is small. It can be made into a trailer-type flow unit and the welded pipe can be produced directly at the construction site where the pipeline is laid. (7) It is easy to realize mechanization and automation. #ASTMA53: Standard Specification for Pipe, Steel, Black and Hot-Dipped, Zinc-Coated, Welded and Seamless Spiral Steel Pipe (SSAW) Application: Used for Oil/Gas/Water transmission, Construction & Structure Parts For more, visit: www.permanentsteel.com or Contact: sales@permanentsteeel.com #oilandgas #spiraltube #pipeline #waterpipeline #construction #steelstructure #manufacturing #tubemanufacturer #pile #port #piping #astma53 #oilfield #ssawsteelpipe #weldedpipe #pipewelding #saw #submergedarcwelding

API 5L X42 #LSAW steel pipe spray #painting finished product effect display There are various #anti-corrosion methods for LSAW steel pipes, mainly including external anti-corrosion coating and internal anti-corrosion coating. External anti-corrosion is simple to operate, generally does not require special equipment, and the cost is low, but it does not perform well in harsh environments such as the ocean. The internal anti-corrosion coating can effectively prevent steel pipes from being corroded and damaged when transporting chemical media such as acids and alkalis. Different anti-corrosion materials and treatment methods can be selected for different usage scenarios and environments. Anti-corrosion treatment of steel pipes can effectively extend the service life of LSAW steel pipes, reduce maintenance costs and improve safety.
