    Two-pipe automatic welding technology Automatic welding eliminates quality blind spots for dairy enterprises Automatic welding eliminates human factors, and there will be no defects such as welding bead dislocation, depression, non-penetration, internal and external protrusions, and no residues of materials, CIP cleaning fluid, and microorganisms

    .


    ​After CIP cleaning, due to the depression or protrusion of the manual weld bead, the cleaning fluid cannot be self-drained in the pipeline, and there is residual milk scale in the pipe.
