Introduction
Surface treatment in pipe processing is a method to improve the properties and appearance of pipes. Various methods are applied to clean, smooth, protect, or refine the surface.
The choice of suitable surface treatment depends on the material and the application area of the pipes. NovaNox® offers you a variety of options for the optimal surface treatment of your pipes. We consider your individual requirements and wishes. Please contact one of our experts to find out how our surface treatment can benefit your project.
Chemical and Mechanical Surface Pre-treatment
Common surface treatment processes include chemical and mechanical surface pre-treatment.
Chemical surface pre-treatment refers to treating metal surfaces with various solutions without the use of electricity. This process removes dirt, grease, rust, or oxide layers, ensuring optimal adhesion and corrosion protection for subsequent coatings.
Common chemical surface pre-treatment processes include:
- Cleaning and Degreasing: This involves rinsing or immersing metal surfaces in organic solvents or emulsifying cleaning agents to remove contaminants such as oil, wax, or dust.
- Pickling: This involves treating metal surfaces with acids or alkalis to dissolve rust or oxide layers and create a smooth and clean surface.
Mechanical surface pre-treatment refers to processing metal surfaces with various tools without the use of electricity. This process removes stubborn contaminants, degreases parts, and roughens or smooths the surface.
Common mechanical surface pre-treatment processes include:
- Grinding: This involves processing metal surfaces with abrasives such as sandpaper or grinding discs to smooth out irregularities and create an even surface.
- Brushing: This involves processing metal surfaces with wire or plastic brushes to remove loose particles such as rust or dust and create a uniform surface.
- Blasting: This involves impacting metal surfaces with blasting media such as sand, glass beads, or steel shot to remove solid contaminants such as old paint or scale and create a rough surface.

We offer various processes, depending on the material and application area of your pipes. We guarantee high quality, safety, and reliability of our services.
Surface Coating at NovaNox®
Surface coating is a crucial process for enhancing the function and appearance of metal pipes. A solid layer of a different material is applied to the metal surface to alter or supplement the properties of the base material.
At NovaNox®, we offer the following surface coatings:
- Painting: A liquid or powdered coating made of plastic or resin is sprayed or dipped onto the metal surface and then dried or cured. Painting serves to protect against corrosion, wear, or chemical influences, as well as for aesthetic surface design.
- Electroplating: A thin layer of another metal such as zinc, nickel, or chromium is electrochemically deposited onto the metal surface. Electroplating serves to protect against corrosion, wear, or electrical influences, as well as to improve the conductivity or lustre of the surface.
- Enamelling: A glass-like coating made of silicates and oxides is melted or fired onto the metal surface. Enamelling serves to protect against corrosion, wear, or thermal influences, as well as to create a smooth and hygienic surface.
- PVD/CVD: Thin layers of metals, alloys, or ceramics are applied to the metal surface through physical (PVD) or chemical (CVD) vapour deposition. These processes serve to improve the hardness, wear resistance, or temperature resistance of the surface.
