Product Description
Seamless tube for high pressure boiler is a kind of boiler tube, which belongs to the category of seamless steel
tube.
High-pressure boiler seamless tubes are often used in high temperature and high-pressure conditions, and the tubes
are subject to oxidation and corrosion under the action of high-temperature smoke and water vapour. The steel tube
is required to have high enduring strength, high oxidation corrosion resistance and good organizational stability.
Seamless tubes for high pressure boilers are mainly used to manufacture superheater tubes, reheater tubes, gas
conduit tubes, main steam tubes, etc. for high pressure and ultra-high pressure boilers.
Low and medium pressure boiler pipe GB3087-2008, high pressure boiler seamless pipe GB5310-1995 is used to
manufacture various structural low and high pressure boiler superheated steam pipe, boiling water pipe and
locomotive boiler superheated steam pipe, large smoke pipe, small smoke pipe and arch brick pipe with high quality
carbon structural steel hot-rolled and cold-drawn (rolled) seamless steel pipe.

Such as the slitting of the stainless steel coil is to cut the stainless steel coil into a corresponding width for further deep processing and pipe making. The process of slitting should pay attention to the scraping of the slitting knife to the coil, the width and error of the strip, In addition, the striping is related to the pipe making process, and the striped cloak and burr are essential for the pipe making process.
