Stainless steel U-tube heat exchangers are suitable for the chemical, petroleum, and pharmaceutical industries

This product is suitable for the chemical, petroleum, and pharmaceutical industries, as well as for liquid-liquid, gas-liquid, and gas air convection heat transfer, steam condensation, and liquid evaporation heat transfer in the production processes of industries such as machinery, electricity, light industry, and textiles.

1. The U-shaped tube heat exchanger allows multiple units to be installed and used in an overlapping manner.

2. Model and its representation method: YA (YB) Dg-S-P tube/P shell NYA, YB-A type (φ 19 × 2) or B type (φ 25 × 2.5) U-shaped tube heat exchanger Dg - nominal diameter of equipment, mm; S - nominal heat transfer area, m2; P tube, P shell - nominal pressure of tube side and shell side, Kgf/cm2； N - Number of tube processes.

3. Nominal diameter Dg (mm): The nominal diameter is divided into 10 levels: 325, 400, 500, 600, 700, 800, 900, 1000, 1100, and 1200.

4. Nominal heat exchange area S (m2): The nominal heat exchange area is 5-650.

5. Nominal pressure Pg (kgf/cm2): The nominal pressure is divided into four levels: 16, 25, 40, and 64.

6. The design temperature is 200OC. It is allowed to be used for temperature rise and pressure drop, with a maximum operating temperature of 400OC. The minimum operating temperature is>-20OC.

7. There are two types of U-tube heat exchangers: 2-tube side and 4-tube side.

8. The U-shaped tube heat exchanger generally has two straight tube lengths of 2500 and 6000mm.

1. Determine the specifications, materials, and quantity according to the above representation method.

2. Indicate the medium name, inlet temperature, outlet temperature, operating pressure, and diameter of each connecting pipe for the tube and shell sides.

3. Indicate the position of the support and the orientation of the pipe mouth, and provide instructions for overlapping installation and use.
