⚡ Free ASME Wall Thickness, Pipe Size & NDT Suite
ASME BPVC Section VIII Div 1 (UG-27 / UG-32) vessel shell & head wall thickness, ASME B31.3 & API 570 in-service corrosion alerts, ASME B36.10M pipe schedules, TEMA RCB-2 U-tubes, and Ultrasonic Testing (UT) Snell's law refraction solvers.
Governing Codes, Formulae & Standards
Authoritative engineering standards integrated into the NDT Exchange calculation models.
UG-27 & UG-32 Vessels
Cylindrical shells (UG-27), 2:1 ellipsoidal heads (UG-32d), hemispherical heads (UG-32f), and torispherical heads (UG-32e) with ASME II-D allowable stress and UW-12 joint efficiency.
U-Tube Bend Radii & Thinning
TEMA RCB-2.31 minimum bend radius limits ($R \ge 1.5 d_o$), RCB-2.32 inner-row PWHT heat treatment triggers ($R < 5 d_o$), and RCB-2.33 extrados wall thinning.
Welded & Seamless Steel Pipe
Covers dimensions, nominal pipe sizes (NPS 1/8" to 24"), outside diameters, wall thicknesses across all schedules, and water hydro-test weights.
Minimum Thickness & Life
Implements ASME B31.3 Eq. (3a) pressure containment thickness plus corrosion allowance, coupled with API 570 §7.1.1 linear corrosion rate and remaining life alerts.
Ultrasonic Refraction
Calculates incident and refracted sound beam angles across wedges and material boundaries, highlighting 1st & 2nd critical angles and beam paths.
Technical guides, CAD geometries, calculations, and flaw criteria are AI-synthesized against industry codes (ASME, API, AWS, ISO) for preliminary reference only. This does not replace certified Level III, PE, or API 510/570/653 sign-offs. Always verify against active governing code editions before field execution.
