Plate work & forming

Sheet layout development, press brake bending, oxy-fuel cutting, cylinder gases and argon purging.

Plate layout development

Plate layout at the neutral line for concentric and eccentric cone frustums, square-to-round transitions, mitered elbows and 90° or lateral branch saddles. Dimensioned drawing, ordinate table by division, area, weight and plate size.

Cone, elbow, saddle

Press brake bending

Flat length of parts with several bends from the K-factor (editable table or DIN 6935), natural air-bend radius, material minimum radius, V die opening, minimum flange, tonnage per foot and total, and press brake selection.

K-factor, V die, tonnage

Oxy-fuel cutting

Cutting and preheat oxygen and fuel gas (acetylene, propane or natural gas) use by steel thickness and cut length, speed, cost per foot and per part, and acetylene manifold size from the withdrawal limit, with editable cutting charts.

Gas use, speed, cost

Gas cylinder contents

Contents of oxygen, nitrogen, argon, argon + CO₂ mix, CO₂, dissolved acetylene, hydrogen and helium cylinders in standard cubic feet, pounds and liquid volume, from water capacity, pressure and temperature with compressibility factor Z; duration and cylinders needed for a usage rate.

ft³, lb, liquid, Z factor

Argon back purge

Argon back purge for stainless pipe welding: volume with or without dams, number of volume changes from the exponential dilution model to the target residual O₂, purge time, gas per joint, joints per cylinder and cost.
