Bond and strength – key factors in coatingsSteel pipes are coated with a corrosion prevention system, either at the factory or on the construction site. When the individual steel pipes are welded together to become pipelines, the coating that was applied in the factory must be partially removed. Once the pipes have been fused together, a new coating is applied to the welded seam to protect them against corrosion and mechanical loads. The sensitive weld seam must be at least as well protected as the rest of the pipe – because a chain is only as strong as its weakest link. In addition to a simple application process, a long-life, reliable corrosion protection solution and good resistance to mechanical loads are also important factors – and the maximum operating temperature must always be taken into account too. DEKOTEC's system solutions offer weld seam coatings for all kinds of processes, including cold or hot processing and sprayable and liquid coatings, e.g. for special applications.
Cold processed – no burner requiredFor weld seam coatings, PLASTELEN® petrolatum tapes and BUTYLEN-PE/butyl tapes can be applied manually using a simple and safe process, without any additional equipment and without a burner. To increase efficiency, manual or motor-powered DEKOMAT® wrapping devices can be used with BUTYLEN-PE/butyl tapes.
The quality standard for corrosion preventionFor almost a century, cold-processed PLASTELEN® tapes have been used as corrosion prevention coating on pipelines at operating temperatures from -40°C to +110°C or -40°F to +230°F. With the invention of the petrolatum tape in 1927, we set the quality standard for passive corrosion prevention.
Millions of metres of measurable successPipelines can be protected against corrosion and mechanical loads quickly and permanently using cold-processed BUTYLEN-PE/butyl tapes. The layers of the tape fuse together, due to the 3-ply structure, to create a protective hose that is fully sealed at operating temperatures of -40°C to +100°C or -40°F to +212°F. Immediately after application, the pipeline can be operated at full load. Many millions of metres of BUTYLEN-PE/butyl tapes have already been successfully applied across the world.
Hot processed – burner requiredDEKOTEC® heat shrinkable sleeves are applied as weld seam coatings using application equipment (a burner).
Tough – even at high temperatures
DEKOTEC® shrink sleeves are a 2-layer or 3-layer (incl. primer) corrosion protection system applied directly to the steel surface. The systems are exceptionally easy to apply with no need to spend time pre-heating the surface (DEKOTEC®-MTS); they are extremely robust at high operating temperatures of up to +90°C (DEKOTEC®-HTS) or boast self-repairing properties (DEKOTEC®-BTS).
