On October 21, 2022, the domestic customer installed the transmission Angle steel tower in the field. The customer recognized the quality and service very much, and is already negotiating related matters for the next order.
      The sharp edge of the Angle steel in the lower part, the section is "V" shape, there is a certain gate seam between the adjacent two Angle steel, the drop pipe is the same as the general tray. The liquid of the upper plate flows into the "V" Angle steel through the drop pipe, and the gas bubbles with the liquid through the gate joint to carry out the mass transfer process. The gas-liquid flow state on the tray is similar to that of the sieve plate. The Angle steel tray pressure drop is small, the gas communication is large, the tray efficiency is good, the structure is simple, the processing and manufacturing is convenient, the stiffness is good.
