Practical engineering tools, project controls, calculators and training resources developed for piping designers and engineers.
Showing Components & Dimensions.
Engineering Calculators
Practical calculators and reference tools for everyday piping design and engineering work.
Piping Design
Calculators & Unit Conversion
NPS / DN / OD Cross Reference
Cross-reference nominal pipe size, DN and outside diameter, with an imperial or metric view.
Pipe by Schedule
Outside diameter and wall thickness by NPS and schedule, including stainless 5S, 10S, 40S and 80S.
Pipe by Wall Thickness
Reverse search of the pipe-schedule extract by wall thickness.
Components & Materials
Flange Datasheet
Flange dimensions by size, pressure class and flange type, for ASME B16.5 and B16.47.
Flange Pressure-Temperature Ratings
Allowable pressure at a temperature, or the temperature limit at a pressure, by material group and class.
Gaskets and RTJ Rings
Spiral-wound, flat ring and RTJ ring gasket dimensions, including R, RX and BX rings.
Line Blanks
Spectacle blinds, spacers and blind disks from an interim manufacturer chart.
Butt-Weld Fittings
Elbow, tee, reducer, cap and long-pattern stub end dimensions from interim manufacturer charts.
Socket-Weld and Threaded Fittings
Forged elbows, tees, couplings, caps, unions and outlets from interim manufacturer charts.
Valve Face-to-Face
Gate, globe, check and ball face-to-face lengths from an interim manufacturer chart.
Butterfly Valve Face-to-Face
Wafer and lug butterfly face-to-face from an interim manufacturer drawing.
Orifice Flanges
Class 300 welding-neck and slip-on orifice flanges from an interim manufacturer catalog.
Steel Sections
W, UB, UC, HE, IPE, PFC, angles, hollow sections and flats from mill tables.
NPT Thread Form
Pitch, taper and sharp height computed from the public thread form.
Component Weight
Look up the stored weight of a pipe, fitting, flange or valve. A catalogue with no stored weight says no weight on record.
Line BOM
Add catalogue components and a quantity. Each row shows the stored description, size, class and weight.
Stainless Tube & Fitting Dimensions
Reference dimensions for stainless steel tube, fittings and related components used in hygienic piping systems.
Flanges
A round plate attached to a pipe, fitting or valve so the joint can be assembled and taken apart.
Gaskets & Bolts
A gasket forms the seal between flange faces, and the bolts hold that joint.
Flange Tools – Downloads
Downloads that sit with the flange articles: a comparison chart, flange data, a pressure-temperature worksheet and an RTJ chart.
