  • How to cleverly solve the problem of oxidation on the back side of stainless steel pipe welding?

    When welding stainless steel pipes in petrochemical construction, the surface of the weld bead and the heat-affected zone are prone to oxidation and discoloration. In order to ensure the corrosion resistance of stainless steel, the weld is pickled and passivated after welding to form a dense layer on the surface.

  • Smart Manufacturing On The Tuyere: Companies Still Need To Be Rational

    Entrepreneurs are desperately chasing the outlet today. For example, the "sharing economy" that exploded some time ago. A group of entrepreneurs swarmed up, and all kinds of shared companies such as "shared bicycles", "shared cars", "shared machine tools", and "shared chargers" emerged for a while. As a result, very few survived after a round of reshuffle. Therefore, although the pigs on the tuyere can fly, when the limelight passes, the pigs all fall to death.
