Pressure safety specialists.

On-site when it matters.

We represent the best pressure safety manufacturers in the industry — and we put our people on-site to make sure the right products end up in the right applications. In the field since 1994, across eight manufacturers, with one team, out of Katy, Texas.

We're more than our product catalog

Any distributor can send you a quote from the comfort of their desk. ARDT shows up at your site, diagnoses the problem, and makes sure your solution actually works.

On-Site Troubleshooting

When a device fails, cycles prematurely, or behaves unexpectedly, we come to the site. We diagnose root causes — not just replace parts.

What a site visit involves

On-Site Training

Hands-on training for engineers, operators, and maintenance craftspeople on pressure safety devices, correct application, and warning signs.

The training catalog

Application & Product Surveys

A structured assessment of your facility’s installed pressure safety equipment — identifying misapplications, risks, and opportunities.

How a survey works

Structured Pricing Agreements

Committed supply relationships with negotiated pricing across your product portfolio. Pricing certainty and supply priority for the long term.

Sizing Assistance

Sizing help for straightforward single-phase applications — and a straight answer about where the work belongs with a process engineer instead.
