Non-conductive coatings and linings on conductive materials like metal can be gently high-voltage tested. Pores, cracks or other damage which may not be visually detected can be reliably identified by pulsed high-voltage. The wide spectrum of ISOTEST inspect applications extends from corrosion protection, weld testing in the plastics field to thickness testing of coated concrete. High-voltage testing equipment is an indispensable aid in quality assurance, in both the initial inspection and production or service.
The construction of tanks and containers, the testing of fully insulated shaped parts and fittings, the construction of pipelines, rubber coatings, lacquer and enamel testing are some of the well-known fields of applications. ISOTEST inspect provides maximum testing capacity and safety – for both tester and test result – even in the event of damp, dirty or low conductive surfaces. Pulsed high-voltage technology related to patented automatic regulation stabilises the testing voltage even under extreme specifications. The microprocessor-controlled sensitivity adjustment ensures a non-destructive test under optimum testing voltage.
Typical Applications
Pipeline construction This is the best-known field of application for the „slogger”of high-voltage testing. By means of spring electrodes (or semicircular brushes) the complete pipe can be checked in 1 – 2 operations. The current versions ISOTEST 4S and ISOTEST inspect 35 have enough power even for large pipe diameters (PDF) and for testing damp pipes.
Industrial facilities The industrial pipeline network is highly strained, particularly the surface pipelines. Modern, non-porous coatings reduce the risk of corrosion and damage.
Protective coating, constructions protection The industrial pipeline network is highly strained, particularly the surface pipelines. Modern, non-porous coatings reduce the risk of corrosion and damage.
Fittings Special test electrodes (like „paint brushes” ) enable the testing even of complex, irregular shapes. The version ISOTEST inspect 8.0 is developed particularly for thin film coatings.
Construction of tanks and containers With the aid of the new optical fibre technology ISOTEST inspect 35 was equipped with extra long high-voltage cable to meet the special requirements within the construction of tanks and containers. As test electrodes rubber, brass or stainless steel flat brushes are recommended.
Tubes Nothing more than a thin pipe! But substantially more flexible and thus equally exposed to danger incurred by the passage of dangerous fluids. The high-voltage inspection of the inner protection coat provides safety.
Batteries, plastic container Less known, but very effective. Testing weld seams of large and small plastic containers e.g. battery housing on density. How? We are ready to consult you.
Other Applications Everywhere where there is a combination of electric conductive materials (metals, acids, concrete partially damp, damp ground...) and non-conductive materials (plastic housing, foils and coating materials, glass...) the non-conductive material can be tested whether it is non-porous or dense.
