Customer Testimonial

"GripSafe plugs have been valuable assets on the LNGC site. The quick and easy installation, use, and removal of the plugs have made testing plain end pipe simple. The Lifting Device makes rigging of the larger plugs into position fast, convenient, and safe. The design of the grippers leave little to no marks inside the pipe. Torque values and plug info on the front plate makes plug identification and double-checking for the right plug usage easy. Overall, the GripSafe plugs are an excellent product."

Pressure Testing Solutions

GSST ISOLATION/TEST PLUGS VS. WELDING END-CAPS

Isolation/Test plugs deliver faster turnarounds, lower costs, improved safety, and greater flexibility than welding end caps on pipe spools—transforming pressure testing from a bottleneck into a streamlined operation.

Head to Head

THE COMPARISON

GSST Isolation / Test Plugs

Recommended

Welding End-Caps

Legacy Method

▲

Speed

Install in minutes with no hot work. Immediate test-readiness with rapid insertion and removal.

▼

Speed

Requires welding, cooling, then grinding off after test. Each cycle adds hours of labor and downtime.

▲

Cost

Reusable across multiple tests. No welders, no consumables, no post-test grinding or NDE required.

▼

Cost

Single-use caps, welder labor, consumable materials, grinding, and follow-up inspections all drive up costs.

▲

Safety

No hot work permits needed. Eliminates arc flash, fumes, and burn hazards. Cold installation process.

▼

Safety

Open flame, arc flash, fumes, and hot metal. Requires hot work permits, fire watches, and PPE protocols.

▲

Flexibility

Quickly reposition and reuse plugs across different pipe sizes and test configurations as needed.

▼

Flexibility

Each cap is permanently welded and must be destructively removed. Changes require starting over.

▲

Quality Impact

No heat-affected zones. When installed correctly, low risk of contamination or distortion to the pipe spool material.

▼

Quality Impact

Welding introduces heat-affected zones, potential distortion, and requires post-weld NDE verification.

Key Advantages

WHY PLUGS WIN

Faster Turnarounds

Eliminate welding and grinding time. Go from installation to pressure testing in minutes, not hours—keeping your project schedule on track.

Lower Total Cost

Reusable plugs replace single-use caps, welder labor, consumables, and post-weld inspections. The ROI is immediate and compounding.

Improved Safety

Zero hot work means no fire watches, no arc flash risk, no fume exposure, and no hot work permits. A fundamentally safer process.

Greater Flexibility

Quickly adapt to changing test configurations. Reposition plugs across different spools and pipe sizes without rework or waste.

THE BOTTOM LINE

Isolation/Test plugs transform pressure testing from a bottleneck into a streamlined operation—delivering speed, savings, safety, and flexibility that welding end-caps simply cannot match.
