Pipe Elevation Adjustment Guide for Pipeline Construction

Proper pipe elevation adjustment is essential for maintaining correct slope, drainage, and structural integrity in pipeline systems. Shims are the primary tool used to achieve precise elevation corrections at pipe supports.

Why Pipe Elevation Matters

Incorrect pipe elevation leads to drainage problems, stress on pipe joints, and potential structural failures. Every pipe support must be shimmed to the correct elevation to maintain proper pipeline grade.

Tools for Pipe Elevation Adjustment

• Precision shim packs in various thicknesses
• Laser level or surveying equipment for measuring elevation
• Feeler gauges for gap measurement
• ShimSheet app for recording shim data digitally

Step-by-Step Pipe Leveling Process

1. Survey the pipe elevation at each support point
2. Calculate the required elevation adjustment at each location
3. Select appropriate shim thicknesses to achieve target elevation
4. Install shims between the pipe support and structural steel
5. Re-survey to confirm correct elevation after shimming
6. Record all shim data in ShimSheet for documentation

Common Pipe Elevation Problems

Sagging Between Supports

When pipe sags between supports, adding shims at adjacent supports can correct the grade and restore proper drainage slope.

Thermal Growth Misalignment

Operating temperature changes cause pipes to expand and shift elevation. Spring supports and adjustable shim stacks accommodate thermal movement.

Digital Pipe Elevation Tracking

ShimSheet replaces paper shim logs with digital records. Track elevation adjustments, shim thicknesses, and support locations across your entire pipeline project from any device.
