Layer thickness measurement and element composition

The Petrochemical Industry and its Challenges

One major challenge in the petrochemical industry, including Offshore, is corrosion containment. Throughout its operation, equipment, towers, pipes, platforms, centrifugal pumps, valve assemblies (Christmas trees), etc., are all exposed to highly hostile environments. Therefore, the challenge for this industry is to develop products with coatings that are increasingly better at combating corrosion and be able to check their wear on the site where they are being used. The fact that much of the entire structure is made of steel and ‘lives’ with corrosion processes is a reality in the petrochemical market.

The petrochemical market used various anti-corrosion coatings, from paint to galvanised materials, and special coatings such as zinc-nickel, Inconel, and cadmium, to combat corrosion; in some cases, even higher costing coatings, such as Silver, can be used. The guarantee of the quality and durability of these coatings, among other factors, is down to the layer’s thickness and controls required during manufacturing and in-field inspections.

This market is regulated by various standards, such as Pipe Painting (Petrobras N-442 and N-2843), Galvanized Paintwork, Ferrous and nonFerrous Alloys, Composites and Polymer Materials (Petrobras N-1021), Painting of Maritime Exploration and Production Units (Petrobras N1374), Painting of Metal Structures (Petrobras N-1550), Painting of Vessels (Petrobras N-1192), Painting of Machinery, Electrical and Instrumentation Equipment (Petrobras N-1735), Painting of Subsea Equipment (Petrobras N-2037), Painting of Galvanized Towers (Petrobras N-2441) and Painting of Storage Tanks, Spheres and Cylinders (Petrobras N-2913).

Solutions for Layer Thickness Control

MMS Inspection®

The new MMS® Inspection series is the perfect solution to meet the day-to-day requirements for inspecting corrosion protection. The great differential is its robustness, having good performance in extreme conditions, such as those commonly found on platforms or Offshore. Another differential is its portability and connectivity, whereby Bluetooth, Wi-Fi and USB can do data transfer without operators having to write measurement details by hand.


  • The layer thickness measurement of paint or lacquer on Ferrous and Non-Ferrous substrates
  • Ease in managing results, separating them into batches
  • Pre-set according to SSPC PA2 / ISO / ASTM Standards
  • Precise control with an error margin ≤ of 1μm and savings with paint coating
  • Robust and portable, ideal for those who work in field inspection
  • The only one on the market with an IP65 protection level against water, dust and vibration

FMP® Series 

The FMP Series of layer thickness gauges together with our high-precision probes allow for non-destructive and highly accurate measurements of paint coatings and lacquers. Whether it’s for quality control in a manufacturing process, random sample inspection or complete batches, these portable, easy-to-use instruments will meet your needs. With more than 70 different types of probes, even the most difficult jobs, such as measuring on rough surfaces, in holes and tubes, on concave or convex surfaces and many other challenges, can be overcome with one of our special probes.


  • The layer thickness of Inconel, Xylan and other anti-corrosion coatings in the Oil and Gas industry
  • Measuring duplex, paint/zinc and steel layers and reporting the results individually
  • Probes for measuring coating thicknesses from 1.0μm up to 100mm


The FERITSCOPE FMP30 accurately measures Ferrite content in Austenitic and duplex steel using the magnetic induction
method. It is fully portable, and there is no need to destroy the part. Suitable for measurements according to Basler and
DIN EN ISO 17655 standards can be used for laboratory or field applications due to their portability. The FERITSCOPE
FMP30 is recommended for austenitic steel plates and welds on stainless steel, pipes, containers, boilers or other products that are made of the austenitic or duplex steel


  • Ferrite content in Austenitic or duplex steel in a non-destructive way
  • Ferrite content inspection in welds
  • Determining ferrite [content] for corrosion prevention

X-ray Fluorescence Solutions


The Fischerscope® XAN® 500 is a portable instrument for X-ray fluorescence measurements. This equipment is suitable for performing measurements of coating thicknesses on different materials and element analysis from sulphur (S) to uranium (U). The equipment is small in size, making it portable and
allowing the user to use it on his workbench or for field inspections.

The XAN 500 can be suitable for several applications such as:

  • Thickness measurements of layers of Zn, ZnNi, Cd, Ag, NiP and others.
  • Measuring the thicknesses of organometallic materials
  • Galvanic bath solutions (liquids), element analyses
  • Identifying and classifying stainless-steel alloys, Inconel, special steels and others
  • Several applications where portability is required, e.g. Offshore structures and pipework
