API 653 STORAGE TANK INSPECTIONS
In service and out of service inspections are carried out in accordance with API 653 recommendations. Visual inspections are carried out by our API inspectors who are qualified and certified to API 653 requirements. These inspections are supplemented by specialized high-tech testing techniques to enable our clients to be provided with a detailed integrity and condition report including estimated remaining life and retirement dates for the tank.
API 570 PIPING INSPECTION AND CERTIFICATION
- Our API 570 Inspectors have inspected and certified pipelines ranging from large diameter lines used in oil and gas production through to smaller diameter pipelines used in Petrochemical plants, refineries and depots.
- The inspection code covers in-service inspection, rating repair, and alteration of metallic and fiberglass-reinforced plastic (FRP) piping systems and their respective pressure relieving devices.
NON-DESTRUCTIVE TESTING
Non-destructive Examination (NDE) is defined as those inspection methods, which allow materials to be examined without changing or destroying their usefulness. NDE methods are employed to ensure that a WELD meets design specifications and does not contain defects. An NDE method is chosen that has the capability and adequate sensitivity to detect discontinuities in the WELD JOINTS requiring examination for accept/reject evaluation. Discontinuities in welds that are detectable when using NDE methods are Porosity, Incomplete fusion, Incomplete joint penetration, Undercut, Underfill, Lamination, Cracks, Root Concavity, Slag Inclusion Etc.
Below are the NDE methods that RITC (Pty) Ltd offer:
Ultrasonic Testing:
Surface Flaw Detection:
Radiographic Testing: (RT)
Advanced NDT:
NDT VIA ROPE ACCESS
Rope access is an advanced access method that is used as an effective alternative to conventional scaffolding or cradle systems. Personnel are highly skilled in rope access techniques and related activities with accreditation conforming to the relevant codes of practice. The teams involved on a job are normally IRATA certified Level 1, Level 2 and Level 3 technicians.
NDT and Inspection methods that can be carried out using Rope Access are the following:
- Magnetic Particle Examination. (MT)
- Liquid Penetrant Examination (PT)
- Ultrasonic Examination. (UT)
- Thickness Measurements. (UTM)
- Radiographic Examination. (RT)
- Positive Material Identification testing. (PMI)
- Visual Inspection. (VT)
