Pipe Shim Thickness Chart & Selection Guide

Selecting the correct shim thickness is critical for proper pipe support and alignment in pipeline construction. This guide covers standard shim thicknesses, common material options, and how to choose the right shim for your application.

Standard Pipe Shim Thicknesses

Pipeline shims are available in standard thicknesses ranging from 0.001 inches to 0.500 inches. Common increments include 0.005, 0.010, 0.015, 0.020, 0.025, 0.031, 0.050, 0.062, 0.125, 0.250, and 0.500 inches.

Thin Gauge Shims (0.001" - 0.025")

Used for fine adjustments in pipe alignment. Thin gauge shims allow precise elevation corrections at pipe supports and are typically made from stainless steel or brass.

Medium Gauge Shims (0.031" - 0.125")

The most commonly used range in pipeline construction. Medium gauge shims handle standard elevation adjustments at pipe shoes, saddles, and structural supports.

Heavy Gauge Shims (0.125" - 0.500")

Used for major elevation corrections and load-bearing applications. Heavy gauge shims are typically carbon steel or stainless steel plates cut to specific dimensions.

Shim Material Selection

• Stainless steel shims for corrosion resistance in outdoor and marine environments
• Carbon steel shims for standard industrial pipe support applications
• Brass shims for non-sparking environments and galvanic isolation
• Composite shims for vibration dampening and electrical isolation

How to Select the Right Shim Thickness

1. Measure the gap between the pipe and support surface
2. Account for thermal expansion in the operating temperature range
3. Select shim combinations that achieve the target elevation
4. Document all shim selections for quality control records
5. Use ShimSheet to track shim thickness, material, and location digitally
