Featured Engineering Partner: FLOWKS Valve Inc.
API 6D • ASME B16.34 • ISO 9001 Certified Industrial SolutionsFLOWKS provides specialized calculation engines for control valve sizing (IEC 60534), thermowell wake frequency (ASME PTC 19.3), safety relief valves (API 520), and flange assembly torque (ASME PCC-1), engineered directly for oil & gas, chemical, power, and water infrastructure.
Control Valve Sizing Calculator
Industrial-grade control valve sizing per ISA-75.01.01 and IEC 60534-2-1. Computes Cv/Kv, choked flow, cavitation severity, and aerodynamic noise for liquid, gas, and steam streams.
Thermowell Wake Frequency Calculator
Evaluates vortex-induced vibration (VIV) and lock-in resonance risk for thermowells, sampling probes, and sensor insertions per ASME PTC 19.3 TW-2016 across 22 industrial alloys.
Flange Bolt Torque Calculator
Computes required target bolt torque, gasket stress, and bolt preload values for ASME B16.5 and B16.47 bolted flange connections compliant with ASME PCC-1 guidelines.
Safety Relief Valve (PSV) Sizer
Calculates required effective discharge area and selects standard letter orifice designations (D through T) for pressure safety relief valves per API Standard 520 / 521.
Flange Dimensions & Ratings Tool
Interactive engineering reference for ASME B16.5 pipe flanges. Instant lookup for bolt circle diameter (BCD), bolt count, hole size, facing dimensions, and pressure classes 150 to 2500.
Pipe Wall Thickness Calculator
Determines minimum required pipe wall thickness, internal pressure design limits, and corrosion allowance verification per ASME B31.3 Process Piping and API 5L line pipe standards.
Flow Coefficient (Cv / Kv) Converter
Fast calculation and bidirectional unit conversion between Imperial Cv and metric Kv/Av flow factors across varying fluid specific gravities and differential pressures.
