LSAW steel pipes named longitudinal submerged arc welded pipe, it's
a advantage of high reliability and safety performance, the lsaw
pipe is widely used in various pipelines engineering and
construction, even under the most severe condition, and also can be
used in engineering of chemical industry, electric power,
irrigation, construction and piling etc.
