Product Description
TEMA Heat Exchanger HP LT Preheater Shell and Tube Heat Exchanger Straight Tube Bundle
A High-Pressure Low-Temperature (HP-LT) preheater shell and tube heat exchanger engineered for binary geothermal power plant operations. Built as an ASME Section VIII Division 1 stamped TEMA heat exchanger, the unit handles n-Butane C.G. on the shell side and geothermal brine on the tube side. Heat exchange occurs via a straight tube matrix, with each individual shell offering 2,605m² of active thermal surface area.
Note: High-density finned tube bundle options can be adapted for specialized gas-phase applications requiring enhanced external surface area per project criteria.

Core Technical & Fabrication Features
  • ASME Code Stamped Structural Design: Designed, fabricated, and stamped in full compliance with ASME Boiler and Pressure Vessel Code Section VIII, Division 1 and TEMA Class C standards.
  • Optimized Tube Layout Pattern: Contains 19.05 mm OD tubes arranged in a 30° triangular pitch pattern 25.4mm pitch to achieve uniform fluid velocity and thermal efficiency.
  • Corrosion-Resistant Weld Overlay & Cladding: Features 10 mm minimum SS 316L weld overlay on the SA-266 Class 2N tubesheet and 3 mm minimum SS 316L explosion/weld cladding across internal channel surfaces.
  • Tube-to-Tubesheet Joints: Tubes are expanded and strength-welded to the tubesheet, accompanied by a helium leak test and hydrostatic validation.
  • Dual-Shell Stacked Configuration: Structural saddle layout and nozzle orientations support both standalone horizontal mounting and two-shell stacked arrangements (PH1001A bottom, PH1001B top).
Quality Assurance & Testing Specifications
  • Radiographic Testing (RT): 100% full radiographic examination (RT-1) on all longitudinal and circumferential pressure-retaining butt welds.
  • Non-Destructive Examination (NDE): Ultrasonic Testing (UT), Liquid Penetrant Testing (PT), and Magnetic Particle Testing (MT) performed per code and contractual specifications.
  • Hydrostatic Pressure Testing: Factory shop hydrostatic test calculated by the vendor to the maximum value required between ASME Code and project specification rules.
  • Tube Joint Verification: Strength-welded tube-to-tubesheet connections subjected to helium leak testing prior to final hydrostatic pressure testing.
  • Material Traceability: All pressure-retaining parts, internal components, and welded attachments supplied with EN 10204 Type 3.1 material test certificates.

We use this for oil refinery bypass cooling. Despite the dust and ambient heat, the thermal performance hasn't dropped. The external coating is thick and very resistant to corrosion.

Fast delivery and easy install. We scaled up our fertilizer plant and needed a quick turnaround. The lead time was better than expected. Flange alignments were perfect, which made the onsite installation very straightforward.
