ASME VIII Div.1 TEMA R Shell and Tube Heat Exchanger Heavy-Duty Oil & Gas Refinery Team Heat Exchanger

Product Attributes & Technical Specifications

3. Product Description

3.1 Product Overview & Core Applications

This pressure vessel is a heavy-duty shell and tube heat exchanger engineered strictly in accordance with ASME Section VIII Division 1 and TEMA Class R standards. It is designed specifically for harsh operating conditions, including high-pressure, high-temperature, and sour service environments in petroleum refining, petrochemical processing, and offshore/onshore natural gas treatment facilities.

Engineered and delivered by our dedicated technical specialists, this team heat exchanger solution complies fully with stringent EPC and end-user specifications, including those from Mott MacDonald, Petrojet, and Kuwait Energy, ensuring long-term structural integrity and optimum thermal efficiency.

3.2 Core Components & Material Specification

3.3 Core Technical & Engineering Advantages

• High-Precision Tube-to-Tubesheet Joints: Incorporates a Strength Welded + Strength Expanded joint design to eliminate crevice corrosion and prevent stress corrosion cracking (SCC) under cyclic thermal loads.

• NACE MR0175 Compliance for Sour Service: All ASME SA-516 Gr. 70 N pressure-retaining plates undergo strict ladle heat analysis, microstructural examination, and HIC/SSCC testing.

• TEMA Class R Erosion Protection: Outfitted with heavy-duty Impingement Baffles at nozzle inlets to protect internal tube bundles from direct fluid erosion and high-velocity impingement.

• Modular Integration: Engineered by our professional team heat exchanger specialists with integrated lifting lugs, alignment pins, and standard flange interfaces to streamline field installation and maintenance.

3.4 QA/QC Specifications & Non-Destructive Testing (NDT)

• Non-Destructive Examination (NDE):

  • RT (Radiographic Testing): 100% volumetric examination on all full-penetration butt welds of the shell and heads per ASME Sec. V.

  • UT / MT / PT: 100% Ultrasonic Testing on tubesheet forgings, alongside Magnetic Particle / Liquid Penetrant Inspection on nozzle corner welds.

• Post-Weld Heat Treatment (PWHT): Conducted in a computer-controlled furnace for pressure-retaining shells and channels to relieve residual welding stresses in compliance with ASME Code requirements.
