Product Description
ASME Section VIII Div. 1 TEMA Class BKU Heat Exchanger Shell and Tube Heat Exchanger

ASME Section VIII Div. 1 TEMA Class BKU Heat Exchanger Shell and Tube Heat Exchanger

Reboiler kettle-type shell and tube heat exchanger designed for CO₂ removal plants in direct reduced iron (DRI) facilities. Manufactured as an ASME Section VIII Division 1 stamped TEMA heat exchanger, the shell side processes MDEA stripping solution while low-pressure steam flows through the tube side. The unit features an expanded kettle shell cross-section (1,649 mm ID / 2,730 mm ID) with an internal overflow weir plate to facilitate vapor-liquid separation across a 670 m² active heating surface.

Note: High-density finned tube bundle configurations can be integrated into specialized gas-phase recovery circuits requiring enlarged external heat transfer surface areas.

Core Technical & Fabrication Features
  • ASME Code Stamped Kettle Construction: Built to ASME Section VIII Division 1 and TEMA Class BKU specifications, featuring an asymmetrical kettle shell geometry to accommodate phase-change vapor disengagement.
  • U-Tube Matrix Layout: Incorporates 25.4 mm OD SA-213 TP316L seamless tubes bent into a U-tube configuration to allow unrestricted thermal expansion during thermal cycles.
  • Internal Weir Plate Disengagement: Integrates a full-height internal overflow weir plate dividing the boiling zone from the liquid draw-off compartment.
  • Tube-to-Tubesheet Joints: Tubes are expanded and strength-welded to the SS 316L cladded face of the SA-516 Grade 70 tubesheet.
  • Post-Weld Heat Treatment (PWHT): Shell-side carbon steel pressure-retaining weldments undergo stress relief heat treatment per ASME Section VIII Division 1 rules.
Quality Assurance & Testing Specifications
  • Radiographic Examination (RT): Spot radiographic testing (RT-3 / ASME UW-11) conducted on longitudinal and circumferential main shell seam welds.
  • Liquid Penetrant Examination (PT): 100% liquid penetrant testing executed on tube-to-tubesheet strength welds and SS 316L overlay surfaces.
  • Hydrostatic Pressure Test: Shop hydrostatic pressure test performed in horizontal position at 10.5 bar(g) on the tube side and 5.3 bar(g) on the shell side using treated water.
  • Surface Preparation & Coating: External carbon steel surfaces blast cleaned to ISO 8501-1 Sa 2.5 (Near-White Metal) and coated with high-temperature primer and topcoat.
  • Material Certification: All pressure-retaining components, flanges, and structural attachments furnished with EN 10204 Type 3.1 material test certificates.
International Logistics & Market Support
  • Internal Nitrogen Purge: Shell and tube chambers thoroughly dried after hydrotest and sealed with a positive pressure nitrogen blanket for overseas transit.
  • Structural Support Saddle Interface: Outfitted with dual heavy-duty steel saddles featuring 12.7 mm base plates, sliding slots (38×76 mm), and 3 mm SS 304 isolation plates under sliding pads.
  • Export Compliance Documentation: Delivered with ASME Form U-1A Manufacturer's Data Report, complete MTR dossiers per EN 10204 3.1, NDE inspection logs, and pre-cleared documentation for North African and Middle Eastern customs release.

We integrated this into our natural gas processing line. The fixed tube design is very compact and fits our layout perfectly. You can tell the materials are heavy-duty—it handles high pressure without a sweat.

The SA516 Gr485 material is known for its low-temperature toughness, and the vendor confirmed the impact testing met our specifications. Shipping to a remote location is always challenging, but the crating was heavy-duty and protected the unit during the long truck haul.

The ASME VIII-1 certification gave us confidence in the design, and the SA516 Gr485 shell thickness was verified upon arrival—it matched the datasheet exactly. What really stood out was the after-sales support; when we had questions about the gasket specifications during installation, the technical team responded within hours via WhatsApp. The unit has been running 24/7 for two months now, handling our solvent recovery process efficiently.
