External Coating
Surface preparation, 3LPE/3LPP, epoxy, fusion bonded epoxy coatings, Flow coat epoxy, solvent free epoxy, cement mortar linings and marking. Our principal is high quality and care in coating field as it is in the production of steel pipe.
Internal Lining & External Coating
In order to prevent steel to be affected by corrosive environment, the pipes are covered with various materials according to its usage purpose. According to the customer needs, different coating choices may apply such as 3 layers PP/PE, epoxy, thoroughly de-oiling, de-rusting and de-dusting of the surface to be covered is performed through special sandblasting machine on Sa 2½ level.
Surface Preparation
Tosçelik applies surface preparation with utmost care to obtain satisfactory surface roughness and cleanliness and assure high performance of its coating / lining applications.
The cleanliness of the blast-cleaned surface shall be as per requirements of coating system, i.e. Sa 2½ or Sa 3 in accordance with ISO 8501-1.
3LPE (Three Layer Polyethylene Coating)
Tosçelik 3LPE System is a multi-layer coating composed of three functional layers. This anti-corrosion system consists of fusion bonded epoxy (FBE) for corrosion protection followed by an adhesive and outer layer of polyethylene which provides tough, durable protection with moderate to high operating temperatures. Tosçelik 3LPE System provides excellent pipeline protection for Tosçelik Spiral Pipe.
3LPP (Three Layer Polypropylene Coating)
Tosçelik 3LPP System is a multi-layer coating composed of three functional layers. This anti-corrosion system consists of fusion bonded epoxy (FBE) for corrosion protection followed by an adhesive and outer layer of polypropylene which provides the toughest, most durable protection with high operation temperatures and high abrasion environments. Tosçelik 3LPP System provides excellent pipeline protection for Tosçelik Spiral Pipe.
Fusion Bonded Epoxy
FBE can be applied as a stand alone system or as a First layer of 3 layer systems in order to provide anti-corrosion protection. Its superior adhesion properties provide excellent resistance to cathodic disbondment which reduces the total cost of cathodic protection during the operation of the pipeline.
Epoxy Coating
Tosçelik performs several methods of epoxy paint applications, in accordance with project Epoxy Coating requirements, through inner and outer spraying method, in cool or hot way. Flow coat epoxy is used in natural gas pipes, where as solvent-free epoxy in water pipes, and coal tar epoxy or glass flake apply for piling pipes. Moreover, hot polyurethane paint apply for waste water and drainage lines.
Robotic Marking
TOSÇELIK SPIRAL PIPE has online pipe tracking systems and make robotic marking on outside and inside of the pipe in order to easy and reliable identification of the pipe ID.
