Spring Hanger & Pipe Support Shim Guide

Spring-loaded pipe supports require careful shimming to ensure proper load distribution and thermal movement accommodation. This guide covers shimming for variable spring hangers, constant spring supports, and spring cans.

Types of Spring Pipe Supports

Variable Spring Hangers

Variable spring hangers allow vertical movement while supporting pipe weight. Shims at the base connection set the initial cold position for proper spring travel range.

Constant Spring Supports

Constant spring supports maintain consistent force throughout their travel range. Base shims ensure the support is installed at the correct elevation for design operating conditions.

Spring Can Supports

Spring cans are compact spring supports used where space is limited. Shims between the spring can base and structural steel set the pipe to design elevation.

Shimming Spring Supports

1. Verify spring support cold load setting matches design
2. Measure required elevation at support location
3. Calculate shim thickness needed for cold position
4. Install shims and set spring support to cold lock position
5. Verify pipe elevation matches isometric drawings
6. Record all shim and spring data in ShimSheet

Track Spring Support Shims with ShimSheet

ShimSheet helps you document spring support shim data alongside regular pipe support records. Track cold settings, shim thicknesses, and travel indicators all in one app.
