ASME Certificated Tovwer OVHD Trim Condenser for Crude distillation unit

ASME Certificated Tovwer OVHD Trim Condenser for Crude distillation unit.

YUHONG ASME-certified Tower OVHD Trim Condenser​ is a critical heat exchange equipment designed for crude oil distillation units, engineered to ensure efficient heat recovery and operational reliability under stringent industrial conditions.

Design & Configuration

• Nominal Size: ∅1100 (Inner Diameter) × 4500 mm (Length).
• Tube Details: 1092 tubes with a size of ∅20×1.8 mm, arranged in a 45° tube pattern​ with a pitch of 26 mm. The tube bundle length is 4500 mm, and the total heat transfer surface area reaches 308.0 m².
• Flow Arrangement: 1 shell pass and 6 tube passes, paired with SEGM vertical-cut baffles​ (220 mm spacing, 17 pcs) ​

Material Selection & Corrosion Protection

• Shell/Heads/Nozzles/Baffles/Tubesheet/Flanges: SA 516 Gr.70 + 2mm cladded with SB 127 (for shell, heads, nozzles, baffles, tubesheet) and SA 105 (tube-side flanges) / SA 106 (shell-side nozzles) – all with 2mm SB 127 cladding.
• Channel: SA 516 Gr.B (with 3 mm corrosion allowance).
• Tubes: SB 165 (corrosion allowance: 0, as internal/external conditions allow).
• Supports: SA 36 (carbon steel, suitable for structural support).
