Tuffchem Environmental Services with collaboration with TechCorr, can provide clients with non-destructive testing and inspection services.
Some of the techniques we provide are:
LONG RANGE ULTRASONIC TECHNIQUE
Unlike UT which in spot inspection at various clock positions on pipelines; LRUT does 100% scanning of the pipeline from a single location. It can inspect inaccessible areas like offshore risers & offsite piping, road crossings, dykes, culverts, in-cased pipelines etc. LRUT is used as a screening tool by all of the major Oil and Gas companies for more than 10 years now.
PULSED EDDY CURRENT (PEC)
PEC is used for Corrosion under Insulation (CUI) applications and in this technique thickness measurements can be made through any type of non-metallic coatings / insulations without removal of insulation / coatings. Typical applications are Concrete coated Horton Sphere Legs, Insulated pipelines, brick lined / concrete coated Vessel Skirts etc. PEC inspection can be done online without disturbing the operations even at high or at sub- zero temperatures. Inspection of underwater marine coated/ cemented coated pipelines, columns and structures can be done with the help of a diver.
SHORT RANGE ULTRASONIC TESTING (SRUT)
Corrosion under Tank Annular Plates (CUTAP) is one of the areas where SRUT technique is used to find out active corrosion while the tank is in service. Other applications involve Testing Concrete Coated Interfaces, Corrosion under Pipe Supports (CUPS), Tank Dyke Piping Interfaces, Saddle supports for pipes and vessel etc.
ACOUSTIC EMISSION TESTING (AET)
It involves detecting, locating and measuring the severity of sources of emissions in structures /equipments. Applications include Inspection of tanks for leaks, corrosion & grading, Inspection of vessels etc. Continuous monitoring of Bridges & Aircraft structures are other applications apart from Oil & Gas sector.
ONLINE TANK INSPECTION
It’s an online inspection system that inspects and assesses the condition of bottom plate in above ground storage tanks. It is specially designed to evaluate the integrity of tank floor bottoms and complies with the American Petroleum Institute’s (API) tank floor inspection guidelines.
AUTOMATED CORROSION MAPPING
Automated Corrosion Mapping is an ultrasonic technique utilized to scan one-hundred percent of a steel surface to locate size and document damage associated with the equipment being inspected. Applications include in-service scanning of vessels, tank walls, frac towers, drums, steel plate, in-line inspection validations and numerous other applications. This would also include the inspection of high temperature assets using corrosion mapping.
Tubular Inspection is for theinspection of ferrous and non-ferrous tubes (plain and finned tubes) through Eddy Current Testing (ECT), Remote Field Testing (RFT), DC Saturation Eddy Current Testing, and Internal Rotating Inspection System (IRIS).
