Pipe Support Selection & 3D Assembly

Variable Springs (Fig. PTP-1/2/4/6/8) · Compact Springs (DST CS/SS) · Fig. 400 · Hanger Hardware — built on Piping Technology & Products catalog data

Design Inputs

Sign convention (matches the PT&P/DST programs): movement is installed → operating. Pipe UP ⇒ installed (cold) load > operating load. Variability = (movement × spring rate) / operating load, MSS SP-58 limit 25%.

Recommended Pass Pass w/ caution (>80% of range or >20% variability) Fail

3D Assembly Drawing drag = orbit · wheel = zoom · shift-drag = pan

Bill of Materials capacities checked vs. max of hot/cold load

Assembly Configuration

Rod size is auto-selected: the larger of the spring's tapped rod size and the smallest rod whose PT&P 650°F rating carries the governing load. C-C solver reports required rod cut lengths using catalog take-outs.

Project Data

"Add to Report Manager" saves this datasheet (inputs, selection, BOM) into the PipeCalcPro Report Manager — same project store as every other calculator. "Send to ISO Drawing" hands the selected hanger assembly (spring, rod, hardware BOM) to the ISO Drawing tool, which offers to place it as a tagged support on the isometric.
Engineering data embedded from Piping Technology & Products, Inc. published catalog pages & selection programs (pipingtech.com): Variable Spring Load & Travel Table (SPRING_LOADTABLE 09/10/09), Fig. PTP-1/2/4/6/8 dimension tables, Fig. 400 table, DST Compact Spring CS/SS selection programs (6/19), and hanger hardware figures 20–140. Three published load-table typos corrected (size 220 @ row 6, size 120 @ row 26, PTP-8 rate @ size 220). This tool is a design aid — final selections must be confirmed with PT&P and project pipe stress analysis. Not affiliated with PT&P.
