Visual Inspection

Keeps surfaces free of erosion, corrosion and irregularities. Includes complete visual inspection and assessment of inside bores in all flowline equipment, terminal connections, and seal surfaces.


Ultrasonic wall thickness measurements

Precisely measures multiple critical areas in each piece of equipment to detect erosion and determine if wall thickness meets specifications.


Cleaning of wing end and thread end


Magnetic particle test (MT)

A magnetic field is induced in the component being tested using a yoke. Fluorescent magnetic articles suspended in water are then applied. If surface discontinuities such as rounding, cracks or other linear discontinuities are present in the parts, they will be detected



Pressure testing up to 30,000 PSI capacity.


Identification and banding

Color-coded or stainless steel bands with serial numbers, pressure ratings and inspection dates, will be applied to all recertified equipment.


Inspection reports

Inspection reports will be available in easy-to-use electronic format. Pressure Test reports is generated using our proprietary testing and datalogging software COMPRESSTM. Customers can also access the reports via an online database.
