TECH NOTES — INDEXPractical guides for engineers and buyers specifying pipe supports — the same sizing logic our engineering team applies to your hanger schedules. Use them to write cleaner RFQs, or skip the reading and send us your support schedule — we do the selection for you.
MSS SP-58 Hanger Types, Explained
What the standard covers, the commonly specified component types, and the A–G spring hanger installation arrangements.
Variable vs Constant Spring Hangers
How each type carries load through travel, the 25% variability rule, and which one your line actually needs.
Spring Hanger Selection Guide
Step-by-step sizing method with a worked example — from hot load and travel to spring rate, size and cold load.
Spring Hanger Installation Guide
Travel stops, hydrotest sequence, preload release and hot position checks — the field procedure end to end.
Pipe Support Spacing Table
Suggested maximum spans for CS pipe in water and steam service — ASME B31.1 practice, in feet and meters.
How to Read a Hanger Schedule
Every column decoded, one worked example row, and the unit traps that cause wrong deliveries.
What to Send for a Quotation
The minimum data per support type, the formats that work, and the three missing fields that stall most enquiries.
Coatings & Finishes for Pipe Supports
Primer, epoxy, HDG or bare stainless — and the zinc rule that governs supports touching stainless and alloy pipe.
How to Specify a Variable Spring Hanger
The load, travel, installation and connection data needed to prepare a clear spring hanger enquiry.
Pipe Shoe vs Guide vs Anchor
How the three support functions differ and which project details should accompany an enquiry.
Clevis Hanger vs Pipe Clamp
A technical comparison of component interfaces, drawing clues, insulation inputs and two-bolt, three-bolt and riser patterns.
Beam Clamp & Eye Nut RFQ Checklist
Confirm drawings, structural and mating interfaces, quantity basis and open TBC items before comparing quotations.
Pipe Support Submittal Package Checklist
Align support tags, drawing revisions, BOM lines, quantity basis and loose items before supplier review.
Crate, Packing List & Tag Reconciliation
Match package marks, packing-list lines, quantities and pipe-support tags while keeping unresolved fields visible as TBC.
Pipe Support Manufacturing: What Buyers Should Verify
Connect registered cutting, forming, welding and inspection processes to the drawing, order plan and required release evidence.
Constant Support RFQ Checklist
Control load, travel, direction, arrangement, interfaces, drawings and open TBC items for every support tag.
