TEMA BEM Shell and Tube Heat Exchanger Heat Exchanger Tube Bundle with Expansion Joint
This vertical TEMA BEM heat exchanger is manufactured for industrial thermal transfer operations involving Low-Pressure Steam (shellside) and Oil (tubeside). The unit accommodates a total thermal duty of 339 kW with an effective heat transfer area of 50.481 m². The design is certified under TEMA Class R standards for high-severity petroleum and chemical processing services. The design allows for integration or direct replacement of a finned tube bundle where extended surface area modifications are required.

| Gaskets | Spiral Wound Metal Gaskets (SS304 with Graphite/PTFE Filler) | Installed on both shellside and tubeside sealing surfaces |
| Nozzles | Carbon Steel Pipe / ASME B16.5 Flanges | Shell Inlet: 114.3 mm OD (102.26 mm ID); Shell Outlet: 60.325 mm OD (52.502 mm ID); Tube In/Out: 114.3 mm OD (102.26 mm ID) |
Tube-to-Tubesheet Joint Execution: Tube ends are processed via mechanical expansion followed by automated strength welding to eliminate leak paths under 800.00 kPaG tubeside design pressure.
Thermal Stress Mitigation: Equipped with an integrated Rho-V2 expansion joint on the shell side to absorb differential thermal expansion between the CS shell and SA240 304 SS tube bundle.
Internal Flow Distribution: Features 9 crosspasses with single-segmental baffles set at 300.00 mm spacing, along with 2 pairs of bypass seal strips and passlane seal rods to control stream bypass fractions.
High-Duty Condensing Capability: Designed for shellside LP steam condensation operating at 138.90 °C inlet to 138.00 °C outlet with a total shellside pressure drop of 1.000 kPa.
Surface Layout: 288 plain tubes arranged in a 30° triangular pitch layout (25.000 mm pitch ratio 1.3158) across 4 tube passes (72 tubes per pass).
Hydrostatic Pressure Test: Shell side tested at 1.5x design pressure (hydrotest verified at 800.00 kPaG); Tube side hydrotested according to ASME Sec VIII Div 1 rules.
Non-Destructive Examination (NDE): 100% Radiographic Testing (RT) on shell long-seam and circumferential welds; Liquid Penetrant Testing (PT) on all strength-welded tube-to-tubesheet joints.
Material Certification: Mill Test Certificates (MTC) supplied per EN 10204 3.1 for all pressure-retaining components including SA240 304 stainless steel materials.
Tolerance Control: Fabrication tolerances comply with TEMA Class R standards for shell ID, baffle-to-shell clearance, and nozzle orientation.
Lifting & Mounting: Fitted with 4 integrated support lugs (208 mm width, 401 mm height) for vertical installation.
Export Packaging: Ocean-freight heavy-duty wooden crate packaging with internal moisture-barrier vacuum sealing and rust-inhibitor coating on carbon steel surfaces.
Customs Compliance: Product documentation includes Commercial Invoice, Packing List, Certificate of Origin (Form E/CO), MTC, and Third-Party Inspection (TPI) release reports (BV / SGS / TÜV compliant upon request).
Dimensional Summary for Transport: Total shell length 3,786 mm, overall diameter including nozzles 520 mm / 473 mm nozzle projection, dry weight 1,544 kg.
