Product Details


Product Details




LSAW Pipe (Longitudinal Submerged Arc-Welding Pipe), is taking the steel plate as raw material, mold it by the molding machine, then do double-sided submerged arc welding. Through this process the LSAW steel pipe will get excellent ductility, weld toughness, uniformity, plasticity and great sealing.

What is pipeline material API 5L


As early as 1926, the American petroleum institute (API) issued the standard ap-5l, which initially only included A25, A and B steel grades, and later issued several standards, as shown in table 4.Note: API issued U80 and U100 standards in 1972, and later changed to X80 and X100.Before 2000, the world used X70, about 40%, X65, X60 are in 30%, a considerable number of small diameter product pipelines use X52 steel grade, and mostly resistance welded straight pipe (ERW steel pipe).



China's metallurgical industry has made great efforts to develop pipeline steel in the past decade. Currently, it is doing its best to tackle X70 wide plate. Chemical composition and mechanical properties of X70 and X80, such as Shanghai baoshan iron and steel company and wuhan iron and steel company, are listed in table 5 ~ table 9.Table 5 wisco X80 rolled plate performance table 6 grade x70 steel pipe mechanical properties table 7 grade x70 steel pipe bending performance test results table 8 grade x70 steel tube the charpy impact toughness of table 9 charpy impact toughness of high strength pipeline are commonly used on the pipeline line tube type at present (SSAW) spiral submerged arc welding pipe, straight seam submerged arc welding pipe (LSAW), electric resistance welding (ERW).Seamless steel tube is used when the diameter is less than 152mm.



From the end of 1960s to 1970s, spiral welding pipe factory developed rapidly in China. Almost all crude oil pipelines are made of spiral welded steel pipes, and spiral welded steel pipes are also used in a class of "west-east gas transmission" pipelines.The disadvantages of spiral welded steel pipe are large internal stress, poor dimensional accuracy and high probability of defects.According to the expert analysis, should adopt the "two legs walk" policy, one is to the present spiral welding pipe factory to carry on the technical transformation positively, also has the great prospect;



The second is to vigorously develop China's direct seam submerged arc welding pipe industry.ERW steel tubes are widely used at home and abroad for their bright appearance, high dimensional accuracy and low price.
