　　Boiler pipe pickling

　　Generally, chemical and electrolytic methods are used for the acid cleaning of boiler pipes, which can remove the oxide skin of steel pipes. The combination of the two methods can achieve ideal results.

　　Rust prevention of boiler pipe

　　After acid pickling, electrolytic method is used to supplement, remove rust, and polish the surface at the same time of removing rust, which can effectively prevent rust;

　　When cleaning, use solvent or emulsion for cleaning to achieve the function of oil removal and ash removal.

　　The maintenance of boiler pipe must pay attention to the use of scientific methods, in order to effectively extend the service life of boiler pipe, special-shaped steel pipe is economic section steel pipe. It includes non-circular cross section, equal wall thickness, variable wall thickness, variable diameter and wall thickness along the length direction, symmetrical and asymmetric cross section, etc. Such as square, rectangular, tapered, trapezoid, spiral pipe, etc
