welded steel pipe

     When the T-welded steel pipe contains Ni, it has strong corrosion resistance in the acidic environment. In the environment containing sulfuric acid or hydrochloric acid, the higher the content of Ni in the T-welded steel pipe, the stronger the corrosion resistance. In the general environment, just add Cr to T-welded steel pipe can prevent the occurrence of erosion phenomenon. The poor condition of steel strip edge is another important cause of wrong edge. Effect of mass flow rate, heat flux and structural parameters (ratio Dc/D of spiral curvature diameter to T-welded steel pipe diameter) on saturated bubble boiling heat transfer coefficient in vertical spiral pipe.
