Development of 10CrNiCuP(A) Corrosin-Resistant Electrical Welding Tube

This paper describes the trial production technology of 10CrNiCuP(A) electrical welding tube, which has used for making tublar heat-exchange device of boiler in power plant and has good resistance against H,SO. dew point and industrial atmosphere pollution corrosion. It) s product characteristics, groove design, welding technological parameters and corrosion-resistance are also discussed. It is showed that production process is stable, the real material 's quality is reliable 1 and the product performance is excellent by testing product's real materisls and using practically. The products are as same real material's level as foreign, and should be widely applicated.
