Drain pipe diameter: Ф 89 mm

3. Specifications and standards for gas-liquid two-phase flow in equipment

The supplier shall design and manufacture according to the standards of gas-liquid two-phase flow and industry standards.

4. Technical requirements for gas-liquid two-phase flow

4.1 The continuous drainage flow rate can be fully automatically adjusted within the range of 6t/h ± 50%.

4.2 Spray nozzle material: 1Cr18Ni9Ti

5. Other requirements for gas-liquid two-phase flow

5.1 All gas-liquid two-phase flow outer surfaces should be treated with appropriate methods and painted. The primer should be applied before the equipment rusts, and the surface paint should be applied after the primer is dry.

5.2 Transportation and storage measures for gas-liquid two-phase flow

The gas-liquid two-phase flow must be completely dry during transportation, and all openings and flange interfaces must be protected to prevent damage, corrosion, or entry of impurities.
