1 Material Treatments
a. Shot-blasting and Priming
We can shot-blast and prime individual pipe components for you. Furthermore, there is a combined option consisting of
the internal and external shot blasting of fittings or the all-around shot blasting of flanges, followed by a Magnetic Particle
Examination (MPE) test.
• External SA 2.5 shot-blasting
• Internal and external SA 2.5 shot blasting of fittings
• External SA 2.5 shot-blasting and priming using Eurolux alkyd weld primer; approx 20 μ
• External SA 2.5 shot-blasting and priming using Sigmaweld shop primer; approx 20 μ
• External SA 2.5 shot-blasting and priming using Sigmaweld MC zinc silicate shop primer; approx 20 μ
• External SA 2.5 shot-blasting and priming using VLB transparant pipe coating (Eurolux)
• All-around SA 2.5 shot-blasting of flanges
• External SA 2.5 shot-blasting and priming using zinc epoxy; approx 20 μ
b. Chemical Cleaning
In addition to shot-blasting, pipes and pipe components can also be chemically cleaned. Internal and external cleaning then takes
place at the same time. Depending on the contamination of the pipe or pipe component supplied and the desired delivery state
of the product, the overall treatment can be more extensive.
By completely removing the mill scale and other contamination, this cleaning method not only cleans the surface, but also makes
the product vulnerable to renewed corrosion. If no additional treatment is effected, it is recommended that external protection
be provided by applying a thin layer of oil. Internal contamination can be prevented by using plastic caps as a protective measure.
The following options are available to you:
• Degreasing
• Pickling, rinsing and phosphating
• Pickling, rinsing, phosphating and capping
• Degreasing, pickling, rinsing and phosphating
• Degreasing, pickling, rinsing, phosphating and capping
• Pickling, rinsing, phosphating and internal and/or external oiling
• Pickling, rinsing, phosphating, internal and/or external oiling and capping
• Degreasing, pickling, rinsing, phosphating and internal and/or external oiling
• Degreasing, pickling, rinsing, phosphating, internal and/or external oiling and capping
Definition of concepts used above:
Degreasing: contaminants such as oil and grease are removed prior to pickling.
Pickling: removal of layers of oxidation, annealing and mill scale, and corrosion products.
Phosphating: treatment using a hot phosphoric acid solution to prevent rust (temporary protective layer).
Oiling: internal and/or external oiling (up to a maximum of 12 meters) using Shell Ensis Fluid E.
