Static equipment inspections
In contrast to rotating equipment, static equipment is non-moving equipment such as tanks and other vessels. This type of equipment often suffers from a different set of anomalies. Be it related to the conditions that the equipment is put under or to their maintenance.
To spot these anomalies several technics can be used, but the most used ones are the non-destructive technics. we offer a wide range of these inspections as listed below:
Visual inspection (VT) is arguably the oldest and most widely used NDT method there is. This method involves the visual observation of the surface of a test object to evaluate the presence of surface discontinuities such as corrosion, misalignment of parts, physical damage and cracks.
We can also use an endoscope in case some parts of the equipment are not reachable.
Magnetic particle examination (MT) is a very popular, low-cost method to perform nondestructive examination (NDE) of ferromagnetic material. Ferromagnetic is defined in ASME Section V as “a term applied to materials that can be magnetized or strongly attracted by a magnetic field.” MT is an NDE method that checks for surface discontinuities but can also reveal discontinuities slightly below the surface.
Ultrasonic Testing (UT) is a group of nondestructive examination (NDE) techniques that use short, high-frequency ultrasonic waves to identify flaws in a material. They include:
- Phased Array Ultrasonic testing (PAUT): test welding, corrosion, superficial flaws
- Time of Flight Diffraction (TOFD): test welding
- Conventional UT: thickness measurement
Liquid penetrant examination is one of the most popular Nondestructive Examination (NDE) methods in the industry. Liquid penetrant exams check for material flaws open to the surface by flowing very thin liquid into the flaw and then drawing the liquid out with a chalk-like developer. Welds are the most common item inspected, but plate, bars, pipes, castings, and forgings are also commonly inspected using liquid penetrant examination.
Eddy current testing is a non-destructive testing (NDT) inspection method used for a variety of purposes, including for flaw detection, material and coating thickness measurements.
In our case it is solely used for flaw detections in tubes.
Positive material identification (PMI) is an essential non-destructive testing (NDT) method utilized to verify that supplied materials conform to the proper standards and specifications. Specifically, PMI is used to confirm that the chemical composition of the metallic parts has the correct percentage of key elements; this ensures that material properties such as corrosion resistance meets the requirements.
Field Metallographic replication is a non-destructive metallurgical inspection technique that is used for evaluating microstructures of plant equipment such as heaters, boilers, piping and reactors. FMR is a simple process. Using portable equipment, the metal surface is ground and polished to a mirror finish. The polished surface is subsequently etched to reveal the microstructure. A replica of the etched surface is then made with a thin piece of acetate film.
