Kurzbeschreibung des Verlags

A run is set out before it is cut, and every cut length is the end of a chain of arithmetic.

Thirty-seven lessons in six parts cover the geometry a pipefitter or sheet metal worker meets on a run: reading a plan and an isometric, grade and fall, inverts and how they are carried, offsets and rolling offsets, closing the run, take-outs and cut lengths, supports and spacing, anchors, guides and movement, sleeves and penetrations, duct offsets and takeoffs, tolerance and the decision, and the ten-line run check.

The arithmetic that costs material is the take-out. A cut length is the centre-to-centre dimension less what each fitting takes out of it, and one fitting allowance carried wrongly puts the whole run out by the same amount at every joint. Offsets, rolling offsets and closing a run to a fixed point are worked here the same way, step by step, and then set as practice.

WHAT IS INSIDE37 lessons, each with the rule in a shaded box, worked examples with every step shown, a note on the usual error, a note from the field, and four practice questions with answers23 measured diagrams12 worksheets with two variations each and full solutions30 layout problems, each taken from the drawing to the cut length528 practice exercises in fourteen sets, every one with a worked solution>Every dimension, grade, invert, angle, allowance, spacing and tolerance printed here is an example. None of them is a figure for your job, a manufacturer's allowance, or a code requirement. Yours come from the drawings and the specification, the designer, the fitting and support manufacturers, and the codes your jurisdiction has adopted. This book designs nothing, sizes nothing, and sets no tolerance.
