Thermal Products was approached by a regional Paper Mill to design a Semi Instantaneous Process Water Heater utilizing excess steam to trim heat process water for a new product line which required a slightly higher water temperature than what existed already.

Thermal Products designed a skid package that included the following equipment:

  • Skid Assembly  
  • U-Tube Heat Exchanger ASME Code Stamped, Model TPI-06-048-2P to heat 62 GPM water from 35.5F to 68F using 50 psi steam 
  • 3" Steam Valve
  • 1-1/2" Steam Trap
  • 3" 150# Y-Strainer
  • Check Valve
  • 150# Class Butterfly Valves
  • High Temperature Limit Aquastat
  • Temperature Relief Valve
  • Temperature Controller from Johnson Controls
  • Spool pieces and piping
  • Painted

Skid package was then painted to custoemr specifications with a 2 part epoxy

Thermal Products can also offer the following equipment for a skid package to fit your specific application.

  • Pump
  • Shell & Tube Exchanger
  • Plate & Frame Exchanger
  • Electric Circulation Heater
  • Air Cooled Exchanger
  • Isolation Valves
  • Controls package
  • Control Panel
  • Various Materials of Construction

The use of a low finned tube within a shell and tube exchanger is an excellent solution for increasing efficiencies in the cooling or heating of gases and liquids.  When space on your lube oil console or fuel conditioning skid is at a premium, see how Thermal Products can offer a smaller shell and tube exchanger design, using low finned tubes reducing the heat exchanger overall footprint and offering considerable potential to save in terms of materials and heat exchanger fill volumes.

The wide range of dimensions offered by Thermal Products Inc makes these products perfect for a broad scope of applications for oil/gas coolers in consoles, machinery and plant processes.

Low finned tubes increase that outside surface area. By having a finned tube in place, it increases the overall heat transfer rate. This then decreases the total number of tubes required for a given application which then also reduces overall equipment size and can in the long-run decrease the cost of the project.  

Applications Thermal Products has designed low finned tubes within our shell and tube exchangers.

  • Power Generation
  • Oil and Gas Productions
  • LNG NGL LPG Plants
  • Refining
  • Petrochemical and Chemical Processing

Benefits of Low Finned Tubes:

  • Offers 2.5-3 times the external surface area of bare tube
  • Enhanced heat exchanger efficiency means less tube is required to accomplish the same heat transfer as a bare tube
  • Low finned tube can increase the performance of an existing exchanger without the difficult and expensive task of building new shells etc
  • Reduced space and weight can be extremely valuable in offshore production or high elevation distillation columns. Low finned technology can transform large shell and tube exchangers into compact heat exchangers

Thermal Products was asked to replace “In Kind” an older all 316L stainless steel Type BEM with vertical installation at a local food additives company. The existing unit was an 26” x 120” BEMV 316L/304L with 16 passes on the tube side.

Thermal Products was asked to provide an updated performance data sheet, ASME Code Calculations and engineering drawing. When the ASME Code Calculations were completed it was realized that the ASME Code requirements now required an expansion joint to be employed on the shell side. Because this was a “Drop in Replacement” project, meaning all pertinent dimensions needed to be held from the existing to the new installation, the addition of an expansion joint created a small challenge for us to maintain the critical dimensions. The Thermal Products team was not only able to incorporate the expansion joint while meeting ASME code requirements but also our customer need to maintain thermal performance and dimensional requirements.

The construction of the sanitary heat exchanger was as follows:

• 316L stainless steel tubes, tube sheets and heads
• 304L stainless steel balance
• Product surfaces were polished to 32u-inch Ra finish
• Exterior was polished to 40 Ra finish
• Tri-clamp product connection
• Hinged head cover for easy access to tube side for cleaning
• Garlock Gylon 3522 gaskets for food use
• Support legs for vertical installation
• Insulation jacket for outer shell
• Designed to TEMA C guidelines
• ASME Code Stamped

Thermal Products was also asked to provide the equipment dossier that included the following documents:

• Final Arrangement Drawing
• Design specification sheet
• ASME Code data report
• Weld Procedures (WPS, PQR, and WPQ)
• Weld log
• Welder qualification records
• Q350 R4 Visual Weld inspection
• Passivation certification
• Surface finish certification
• ElectroPolish certification
• Material Test Reports (MTR’s)
• Gasket certificate
• Insulation safety data sheet
• Hydro Test Certification
• ASME Code Calculations
• Unit ID plate
