Manufactured by G.A.L. Gage Co., the Cat # 34 Flange Fit-Up and Inspection Gauge (widely known as The Burk Flange Alignment Tool) is an essential precision instrument engineered to streamline the inspection process for industrial flanged connections ranging from 150 lbs to 1200 lbs. Designed specifically for spiral wound gaskets, this tool enables quality control inspectors, pipefitters, and maintenance supervisors to instantly verify proper gasket crush and detect external misalignments, effectively eliminating joint leakage during hydro-testing and plant startups.
Ensuring joint integrity in high-pressure piping systems is critical. The Flange Fit-Up and Inspection Gauge provides a fast, reliable, and standardized visual verification method. Featuring robust stainless steel construction with precision imperial (inch) scale markings, the gauge incorporates dedicated "go/no-go" cutouts that immediately indicate whether a flange joint has achieved correct gasket compression or requires corrective rework. Additionally, the side scale measures external high/low misalignments, while the reverse side displays vital ASME code reference data.
Certification
The Cat # 34 Flange Fit-Up and Inspection Gauge can be certified. The certification is not included in the base price and is available at an additional cost. Just add it to cart if your quality control or compliance standards require it.
Features
- Dual-Function Inspection: Combines gasket crush verification ("go/no-go") and external high/low misalignment checking into a single pocket-sized tool
- Broad Pressure Range: Calibrated for standard industrial flange ratings from 150# up to 1200#
- Spiral Wound Gasket Optimized: Specifically designed for spiral wound gasket applications (Note: Not intended for lap joint flange connections)
- ASME Code Reference: Permanently engraved reference data on the back of the tool for quick on-site code verification
- Heavy-Duty Construction: Fabricated from high-grade, corrosion-resistant stainless steel to withstand harsh shop and field environments
- High-Contrast Markings: Clear, wear-resistant imperial (inch) scale graduations for rapid Reading
Applications
- Petrochemical Refineries: Verifying proper spiral wound gasket compression and flange alignment during unit turnarounds and high-pressure piping maintenance
- Power Generation Facilities: Inspecting flanged connections in fossil, nuclear, and combined-cycle plants to ensure zero joint leakage during hydro-testing and startups
- Engineering and Construction (EandC) Projects: Standardizing fit-up inspections across newly fabricated piping networks to eliminate costly rework and joint failures
- Oil and Gas Upstream and Midstream: Checking flange alignment and gasket crush integrity on critical pipeline headers, compressor stations, and terminal piping
- Industrial Maintenance and MRO: Conducting routine joint verification checks during scheduled plant outages to prevent fugitive emissions and maintain operational safety
Specifications
| Scale | Inch Only |
| Flange Rating Compatibility | 150 lbs to 1200 lbs |

How to Use
- Pre-Check Verification: Confirm that the flanged connection utilizes a compatible spiral wound gasket. (Note: Do not use on lap joint flange connections.)
- Inspect Gasket Crush: Insert the "go/no-go" portion of the gauge into the gasket operating space. A proper fit indicates correct gasket compression; failure to pass indicates insufficient tightening or excessive crush requiring rework
- Check External Misalignment: Apply the side scale of the tool against the flange faces or outer diameter to evaluate external high/low alignment tolerances
- Reference ASME Standards: Cross-reference the measurements with the ASME code guidelines engraved on the back of the gauge
