Attributes
Pressure-Retaining Shell Material: ASME SA-516 Grade 70 (Carbon Steel for Moderate and Lower Temperature Service)
Application: Fabricated for the main shell cylinders, longitudinal seams (LS1, LS2, LS3), and high-pressure channel boundaries requiring superior notch toughness and pressure containment
Forged Flange & Hub Material: ASME SA-105 (Carbon Steel Forgings for Piping Applications)
Application: Utilized for all high-rating heavy-wall nozzle flanges (N8, N7, N9, N10, N11, N12) to ensure robust bolting integrity and zero leakage under thermal cycling
High-Pressure Coupling & Fitting Material: ASME SA-105 / SA-106 Gr. B
Application: Specified for the 1" Class 6000# high-pressure instrument and venting connections (N19, N20, N11, N13, N14) to resist high shear forces
Heat Exchanger Tubes Material: ASME SA-179 / SA-213 Series (Cold-Drawn Seamless Low-Carbon Steel / Alloy Steel Tubes)
Application: The core precision heat exchanger tubes making up the internal bundle matrix, optimized for maximum thermal conductivity and scaling resistance.
External Structural Supports (Saddles): ASME SA-36 / SA-516 Gr. 70
Application: Used for the heavy-duty Fixed Saddle and Sliding Saddle assemblies to manage dead loads and thermal expansion across the longitudinal axis
Material Certification & Traceability: Full compliance with ASME Section II (Materials) Part A & Part D, accompanied by certified Mill Test Reports (EN 10204 3.1) verifying 100% heat traceability.
