Special-shaped stainless steel seamless steel pipe

Abstract

The invention discloses a special-shaped stainless steel seamless steel pipe. The special-shaped stainless steel seamless steel pipe comprises a steel pipe main body and a heating device; the steel pipe is an elliptical steel pipe with the outer part being circular and the inner part being flat; the outer side of the steel pipe main body is fixedly sleeved with the heating device; the top and thebottom of the inner wall of the steel pipe are symmetrically provided with crescent-shaped cavities; and the two crescent-shaped cavities are internally and fixedly connected with compression-resistant components. By forming the crescent-shaped cavities in the steel pipe, manufacturing materials are effectively reduced, the production cost is lowered, through the compression-resistant components in the crescent-shaped cavities, the compressive effect on the outer wall of the steel pipe can be achieved effectively, the compression resistance of the steel pipe body is enhanced, the heating device is fixed outside the steel pipe and can heat the steel pipe, the situation that internal fluid is frozen into ice in cold weather and the conveying effect is affected is avoided, and through an insulation layer filled with polyurethane foam, heat generated by the heating device can be effectively insulated.

Description

technical field [0001] The invention relates to the technical field of special-shaped seamless steel pipes, in particular to a special-shaped stainless steel seamless steel pipe. Background technique [0002] Special-shaped seamless steel pipe is a general term for seamless steel pipes with cross-sectional shapes other than round pipes. Special-shaped steel pipes can better adapt to the particularity of use conditions, save metal and improve labor productivity in parts manufacturing. [0003] The compression resistance of the steel pipe has a certain relationship with the thickness and shape of the pipe wall. The thicker the pipe wall, the greater the pressure resistance and the higher the applicability, but the corresponding cost is higher. When the fluid is used, in some cold regions, the steel pipe is exposed outside. Due to the low air temperature, the fluid in the steel pipe is easy to freeze into blocks, causing blockage in the pipe and affecting the transmission of th...

[0003] The compression resistance of the steel pipe has a certain relationship with the thickness and shape of the pipe wall. The thicker the pipe wall, the greater the pressure resistance and the higher the applicability, but the corresponding cost is higher. When the fluid is used, in some cold regions, the steel pipe is exposed outside. Due to the low air temperature, the fluid in the steel pipe is easy to freeze into blocks, causing blockage in the pipe and affecting the transmission of the fluid. For this reason, we propose a special-shaped stainless steel seamless steel pipe
