Product Data Sheet
The Bituseal®Enamel is based on a specially selected bitumen, modified with high performance engineering polymers. This polymer modification ensures improvements of a number of the product’s qualities, e.g. flexibility, adhesion and durability. Bituseal®Enamel is supplied in different types/grades, depending on the varying requirements for corrosion protection materials for pipelines.
Bituseal®Enamel is available cold in 20 kg block or hot in bulk.
Bituseal®Enamel is applied to steel pipes, previously primed with Bituseal®Primer, at 190-230°C using computer controlled extrusion technology, which ensures an optimum coating quality. Optimum adhesion and bleed-through is obtained when the pipe surface temperature prior to coating is 30-50°C. However, minimum surface temperature is 15°C and 3°C above the dew point. Minimum enamel thickness is 4.0mm.
Heated Bituseal®Enamel is to be stored under constant low-speed stirring. Storage temperature and duration depends on the Bituseal® grade stored.
The Bituseal®Enamel meets or exceeds all the performance requirements of EN 10300.
All raw materials for Bituseal®Enamel are tested and approved in the laboratories of Varziran. The quality of the finished enamel is controlled to either EN 10300 or the the costumer’s specific requirements and a quality certificate is issued for each batch produced.
Bituseal®Enamel is suitable for pipelines operating at temperatures in the range -30°C to 90°C. The enamel is environmentally safe.
A polypropylene shield can be applied to the Bituseal®coated pipe in order to obtain improved mechanical protection of onshore pipelines.
