Primary Design Codes & Classification of GAS GAS SA270 L7 Shell and TP304L Tube Heat Exchangers
The equipment is designed and shall be constructed in strict accordance with the following major international standards:
Heat Exchanger Standard: TEMA (Tubular Exchanger Manufacturers Association) Class R (for severe service requirements).
Industry Standard: API Standard 660 (Shell-and-Tube Heat Exchangers for General Refinery Services).
Material/Metallurgy: Applicable NACE standards for service in potentially corrosive environments.
Load Design of GAS GAS SA270 L7 Shell and TP304L Tube Heat Exchangers
Seismic Design: Designed for seismic loads as per IBC 2018.
Wind Load Design: Designed for wind loads as per ASCE/SEI 7-22.
Design Conditions of GAS GAS SA270 L7 Shell and TP304L Tube Heat Exchangers
Shell Side:
Design Pressure (Internal): 56 barg
Design Temperature: 85°C
Hydrostatic Test Pressure: 72 barg
Tube Side:
Design Pressure (Internal): 58 barg
Design Temperature: 145°C
Hydrostatic Test Pressure: 75.4 barg
Minimum Design Metal Temperature (MDMT): Both shell and tube sides have an MDMT of -41°C. This mandates the use of materials qualified for low-temperature service.
Service & Process Parameters of GAS GAS SA270 L7 Shell and TP304L Tube Heat Exchangers
Shell Side Fluid:Gas
Tube Side Fluid:Compressed Gas
Number of Passes:
Shell Side: 1 Pass
Tube Side: 2 Pass
Fluid Density (Inlet / Outlet):
Shell Side: 61.2 kg/m³ / 48.5 kg/m³
Tube Side: 53.9 kg/m³ / 62.6 kg/m³
Inspection of GAS GAS SA270 L7 Shell and TP304L Tube Heat Exchangers
Joint Efficiency: A joint efficiency factor of 1.0 is applied for both shell and head seams, permitted due to the full radiography.
Post Weld Heat Treatment (PWHT)
Impact Testing
Corrosion Allowance:
Shell Side: 3 mm
Tube Side: 0 mm (indicating a corrosion-resistant material is specified for wetted parts).
This gas-gas exchanger is built for pipeline project duty, with an SA270 L7 shell and TP304L tubes that resist the corrosive and erosive conditions common in gas transmission service. The floating head configuration absorbs differential thermal expansion and keeps the bundle accessible for inspection, which protects availability on critical pipeline installations. NACE-compliant material selection with CE certification addresses sour service requirements, and the design covers pressures to the 56 bar class. Complete documentation, including material certificates and test reports, is supplied with installation support.
