Dkbutyl-System Б 40 is a single cold applied tape system designed for corrosion protection of pipelines in accordance with DSTU 4219-2003. It consists of an adhesion promoting primer Dkbutyl-Primer DK-II, 2-layer tape Dkbutyl-Tape 0.65 and 2-layer tape Dkbutyl-Tape Outer 0.65. Dkbutyl-System Б 40 meets the requirements of load class Б at a maximum long-term operating temperature of 40°C.
– Dkbutyl-Primer DK-II – 2 coats of Dkbutyl-Tape 0.65 - (1 coat with 50% overlap) – 2 coats of Dkbutyl-Tape Outer 0.65 - (1 coat with 50% overlap)
Complete amalgamation of overlapping areas Forms a sleeve type coating Impermeable to oxygen and moisture Resistant to ground loads Co-extrusion technology Maximum corrosion protection combined with outstanding tape flexibility Service life as a part of the protective coating of construction p.7 Table 4 DSTU 4219-2003 is not less than 30 years.
Dkbutyl-System Б 40 is a cold applied corrosion protection system used for coating underground or submerged steel pipelines. Dkbutyl-System Б 40 is used for corrosion protection works on insulation of main water, oil and gas pipelines Ø720, ammonia pipelines ≤530, according to the design of Clause 7, Table 4, DSTU 4219-2003. Dkbutyl-System Б 40 is compatible with the factory coating of PE, PP, epoxy, polyurethane and bitumen. It can be used for field coating joints, recoating coatings and repairing coatings. It is the ideal choice for both small and medium nominal pipe sizes.
