Interactive Tools
Six interactive calculators and reference tools. No downloads. No spreadsheets. Just fast, accurate engineering lookups.
P-T Rating Calculator
Select material, pressure class, and operating temperature. Returns maximum allowable pressure per ASME B16.5 tables.
Bolt Torque Calculator
Compute recommended torque for B7, B16, and stud bolts by size, grade, and lubrication condition. Includes load verification.
Gasket Selector
Match gasket type (flat-face, spiral wound, RTJ) to service condition, pressure, and temperature. Includes sealing surface requirements.
Flange Dimension Calculator
Query ASME B16.5 dimensional data by NPS and pressure class. OD, bolt circle, hole count, and thickness lookup.
Face Finish Reference
RF (Raised Face), FF (Flat Face), RTJ (Ring Type Joint), and MJ (Male Lapped) specifications. Surface finish requirements and gasket compatibility.
Specification Builder
Build a flange specification from scratch. Material, class, facing, thread type, and special machining. Export as plain text.
Deep Dive
Technical White Papers
Four in-depth white papers on design, materials, corrosion, and compliance for engineers and specifiers.
