• 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).

• 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.
