What to Expect from Our Used Equipment Inspection Process

Visual Inspection

Material Thickness Readings

Internal Inspection

A comprehensive visual inspection includes an assessment of all accessible surfaces and components to identify signs of wear, corrosion, cracks, dents, leaks, and other physical damage. The inspection verifies the condition of critical parts such as welds, flanges, couplings, TOL's, and other pressure containing components to ensure structural integrity and safe operation. It also involves checking for evidence of previous repairs, modifications, or non-compliance with industry standards.

Internal Inspection

Material Thickness Readings

Internal Inspection

Our internal inspection offers a comprehensive evaluation of the internal condition of the equipment. We carefully inspect all accessible internal components for signs of damage that may impact performance or functionality. Utilizing specialized tools and industry-standard techniques, we assess the structural integrity and operational readiness of your equipment beyond what is visible externally. Our internal inspection report provides clear, actionable insights into the equipment’s condition, highlighting recommended repairs or refurbishments. This enables you to make informed purchasing or maintenance decisions.

Material Thickness Readings

Material Thickness Readings

Material Thickness Readings

Our inspection process includes taking random material thickness readings throughout used equipment to assess the condition of the vessel wall. By measuring wall thickness at various points, we can detect corrosion, erosion, and wear that may not be visible externally. These measurements provide vital data to evaluate structural integrity and help you plan necessary maintenance or repairs. This proactive approach reduces the risk of unexpected corrosion issues leading to high repair cost, de-rating of vessel, or total loss.

Vessel Nozzle Verification

Vessel Nozzle Verification

Material Thickness Readings

We document and verify vessel nozzle sizes and quantities to ensure accurate configuration details. This information is essential for maintenance, repair planning, and integration with existing systems, helping you identify required equipment modifications to fit your application.

NORM Check

Vessel Nozzle Verification

Detailed Inspection Report

Our used equipment services include comprehensive NORM (Naturally Occurring Radioactive Material) checks to detect and assess any radioactive contamination present on or within the equipment. This critical service helps ensure regulatory compliance, protects the health and safety of personnel, and minimizes environmental risks, giving you confidence that your equipment meets industry safety standards before purchase or use. 

Detailed Inspection Report

Vessel Nozzle Verification

Detailed Inspection Report

We provide a comprehensive, detailed inspection report that summarizes all findings including photos, visual observations, internal assessments, material thickness measurements, and documentation of critical components, giving you a clear and thorough understanding of the equipment’s condition and any recommended actions.
