CONTRACTOR CONSCIOUS NON-DESTRUCTIVE TESTING

The Partner Behind Your Expertise

Our testing reveals what matters most, giving your customers confidence in their next steps and giving you a well‑defined path to support them.

Confidence through insight.

Mechanical Integrity evaluations can feel like guesswork when critical piping and vessel conditions are concealed. Contractors face pressure to provide answers, while their customers need proof to support compliance, budgeting, and maintenance decisions. Without reliable data, everyone is left navigating risk instead of managing it.

We deliver the clarity that traditional methods miss. Our NDT services provide quantitative, defensible information about ammonia refrigeration piping systems—verifying fitness, pinpointing problem areas, and uncovering hidden issues so teams can prioritize work, justify investments, and maintain safe, efficient operations.

I have worked with a few different companies during my previous employment and have found that GGS has provided the best testing method with the most accurate details without impacting the integrity of the refrigeration system. The teams I have worked with in the past have been very professional and focused on their responsibilities which included working safely with our facilities. I continue to promote GGS services due to the detail and solution-based reports that are provided quickly upon completion of the on-site studies as well as the team behind the crew(s) conducting the onsite testing. GGS has been very responsive anytime a question has risen during review of the report.

GGS has been a great partner for our customers. Their technicians know exactly where to look for corrosion and insulation failures, and their site reports clearly document every inspection area. The post‑inspection review call helps us understand all the readings before we present next steps, and their ability to cover multiple sites in one cost‑effective circuit has been a huge advantage for us and our clients.

HOW WE WORK

Our Proven Approach

Our process is designed to support both immediate needs and long‑term Mechanical Integrity goals. Every project is executed with precision, safety, and efficiency by a specialized NDT technician team using proven, non‑intrusive methods that protect your system and your budget.

From flexible scoping to actionable reporting, we deliver accurate, quantitative data that strengthens PSM and RMP programs without disrupting operations.

1

Define the Scope

We tailor each job to your short‑ and long‑term program needs, ensuring the work aligns with PSM/RMP requirements and your budget realities.
2

Deploy Expert Technicians

A two‑man technician team specializing in refrigeration and utility NDT performs all testing with consistency, accuracy, and deep industry experience.
3

Test with the Right Methods

We use only safe NDT techniques that present zero radiation exposure liability. Piping is evaluated using Radiometric Profiling (RP), a non‑intrusive method that does not cut into insulation or jacketing and enables full‑circumference scans on lines up to 24 inches, including elbows, tees, nested, and suspended piping. Vessels are assessed using Ultrasonic Thickness Testing (UTT) to capture accurate, quantitative wall‑thickness data.
4

Capture High‑Volume, High‑Quality Data

We test an average of 150 locations per day, detecting and documenting wall thickness (and loss), moisture in insulation, corrosion, and other critical indicators.
5

Deliver Clear, Actionable Results

You receive a detailed report for PSM, a separate dynamic Excel decision‑making tool that highlights and prioritizes areas of concern, and a review call with you and your customer to walk through the findings together.
Scope Options
01

Client‑Directed Testing

You tell us exactly what you want tested. We focus on the specific areas, lines, or vessels you identify as most important during a single visit.

02

Comprehensive System Testing

A full‑system evaluation completed in one mobilization. We test all vulnerable areas across every pipeline and vessel in your system for a complete mechanical integrity picture.

03

General Condition Testing

A representative sampling across your system. We test a mix of high‑risk areas, visually suspect locations, and general piping to give you a broad understanding of overall system health. Vessels can be included as needed.

Deployment Options
01

Single Visit

We fulfill the entirety of the scope in one mobilization for maximum efficiency and minimal disruption.

02

Progressive Over Time

We divide the work across multiple visits—year over year—until the entire system has been assessed. This spreads out cost, scheduling, and workload while still building toward full coverage.

03

Multi-Site Bundling

If you have multiple customers in the same area, we can test them in a single deployment. This reduces mobilization time and cost, allowing you to pass meaningful savings on to your customer.
