Surface treatments of metals and alloys
The term sandblasting refers to a mechanical process that allows the surface of a metal productto be cleaned of residues and corrosive encrustations, obtaining a finish that ensures a suitable and adequate hold for subsequent painting treatments and application of protective coatings.
Generally, sandblasting is carried out before thepainting treatment to complete the the processing cycle of a workpiece: through a jet of sand and air, launched at great speed and very high pressure, or through the firing of abrasive materialcarried out by rotating turbines, the process allows removing and eliminating, impurities and corrosive slag: paints, rust calcifications, oxides, calamine.
Thesandblasting of metalsgives the object the appearance it had before the surface was altered and modified by oxidation and surface corrosion.
Our systems are suitable for any type of material, size and weight (up to 100 tonnes); for the surface treatment, we use metallic, spherical and cylindrical grit, garnet, glass microspheres, corundum and sand.
The sandblasting of pipes is carried out in our automatic plants in compliance with the ISO, SSPC, ASTM and NACE standards. During the treatment, we use metal and natural abrasivessuch as garnet and corundum. The automatic plant is equipped with a double separator to avoid any type of contamination between steels.
Objects having the following sizes can be processed:
EXT. Ø 2500cm
INT. Ø 250cm L. 12000cm
