The biggest advantage of penetrant inspection is that it can be applied on both ferromagnetic and non-ferromagnetic materials.

Direct and Remote Visual Inspection (VT & RVI)

Despite all the developments in Inspection Technology, visual inspection continues to be the basic non-destructive testing method. There are a variety of situations in which the visual inspection that provides basic data to inform the operation and maintenance process is an option. With Visual Inspection, the material on the surface can show problems such as defects, corrosion or cracks.

INTERCON provides direct visual inspection and visual inspection services with different optical devices (RVI) for manufacturing, maintenance, in-service, condition assessment and damage analysis.

Leakage and Vacuum Box Test (LT & Vacuum Box)

 In closed systems, leakage test allows leak detection and the smallest molecule inert gas helium is used. Helium gas probes are placed on other suitable part of system to detect helium gas, which filled in the system. In simpler systems, the hand detector is placed around the gas filled container on the surface.

Vacuum test (vacuum box) is used for welded structures like weld seams in above ground storage tanks, vessel cargo tank. Weld seams which is wetted by the test fluid and vacuumed, the area is inspected for the visible leakage finding (bubble).

Material tests are one of the important field services of INTERCON. Field material testing services, chemical, physical, microstructure properties of materials are determined and the results are given to the customer quickly and accurately.

MATERIALS TEST

Positive Material Identification (PMI)

Positive Material Identification is rapidly emerging as an internal part of process safety management and quality control in many industries such as electric power generation, construction, manufacturing, chemical processing, oil refineries and petro chemical plants. INTERCON provides material identification and quantitative elemental determination by using modern hand-held, portable X-Ray analyzers, for a wide range of items.

Measuring Ferrite Content

Austenitic, Duplex, Super Duplex stainless steels require adequate proportion of ferrite in the product to obtain acceptable corrosion resistance and strength and especially resistance to stress corrosion cracking (SCC). Ferrite measurement by using ferritscope is a nondestructive test method that assures the quality of the product without the need of expensive laboratory based destructive test method.

Replica Test – Non-Destructive Metallography

Non-destructive metallography is also called a replica test. The replica technique allows the observer to determine the material for the microstructure of the material on the surface of the equipment, which must be inspected without taking any part of the material itself. In this way, the relation between the microstructure and the existing microstructure is revealed.

INTERCON provides direct on-site heat treatment services with portable heat treatment equipment or high-speed burner systems. Our heat treatment services basically have two main heat treatment applications. It is pre-heating and post-weld stress relief before and during welding process. The preheating, de-stressing requirements and parameters depend on the metallurgical structure, thickness and the usage environment of the material according to the relevant standards and codes.

We offer heat treatment services by using heat treatment procedures according to the international standards and codes related to mobile heat treatment equipment suitable for pipelines, pressure vessels and boilers, and other kinds of manufacturing products. Pre-heating, Stress relief etc. We offer Heat Treatment services out of accreditation service.

HEAT TREATMENT SERVICES (PWHT)

Underwater Magnetic Particle Testing This inspection system is a magnetic particle test, which the diver can apply in deep water, shallow waters and tidal waters. The 12-volt rechargeable battery operated DC current hand yoke is tested using a high-intensity UV light source. For inspection equipment the diver does not need a hose connection with the surface.

Alternatively, the magnetic particle inspection medium (test liquid) is delivered to the underwater by pressure equipment, which control by diver and magnetic particle inspection equipment via the surface. In this method, the magnetic particle liquid carrier, spray system and ultraviolet light are integrated.

UNDERWATER SERVICES

Underwater Thickness Measurement

In some underwater corrosion inspection applications, the application is in the form of thickness measurement in the underwater support piles and the underwater parts of the above water structures. Some applications require working in a deeper water environment. INTERCON has a very good application and evaluation experience in underwater thickness measurements, and has thickness gauges having a special probe and cable that can be used in both shallow and deep water.

Underwater Visual Inspection

 There are three types of underwater visual inspection, general visual inspection, close visual inspection and detailed visual inspection.

General visual inspection does not require cleaning, can be performed with diver or ROV. Close and Detailed Visual Inspections require wire brushes, high-pressure water jets and levels of cleaning up to underwater blasting. These two types of inspection allow the diver to collect data on damages such as thickness measurement, pitting corrosion, abrasion. This level of cleaning also allows cathodic protection, underwater eddy currents and underwater magnetic particle testing. INTERCON can carry out underwater visual inspections with diver, ROV & Underwater Drones.

INTERCON has a wide range of services for destructive testing. Determining the mechanical properties of materials with accurate results is of great importance for the industry. INTERCON conducts inspections such as tensile, notch impact, crack tip opening displacement (CTOD), bending, hardness, creep, break, nick break, slip factor, nut stripping test, hardness distribution, micro and macro structure according to international standards. Destructive tests, which are the requirements of the welding process test and welder tests, are carried out in accordance with the standards such as ASME, AWS, API, and EN ISO.
