Abstract
The invention discloses a corrosion-resisting heat supply steel pipe structure. The corrosion-resisting heat supply steel pipe structure comprises a stainless steel pipe body. A zinc coating is arranged outside the stainless steel pipe body, and a heat insulating and preserving layer is arranged outside the zinc coating. The stainless steel pipe body comprises, by mass, 0.2-0.25% of C, 0.6-0.65% of Ni, 3.5-4.5% of Cr, 3-3.5% of Mn, 0.05-0.06% of S, and the balance of iron and inevitable impurities. According to the mode, the corrosion-resisting heat supply steel pipe structure is simple and reasonable, suitable for being laid in the corrosive environment and good in heat insulating and preserving performance.
Description
Technical field
The present invention relates to technique of pipe field, particularly relate to a kind of corrosion-resistant heating steel-pipe construction.
