Bituseal Enamel

Product Description of Bituseal Enamel

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. It is supplied in different types/grades, depending on the varying requirements for corrosion protection materials for pipelines.

Application of Bituseal Enamel

It 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 are obtained when the pipe surface temperature prior to coating is 30-50°C. However, the minimum surface temperature is 15°C and 3°C above the dew point. Minimum enamel thickness is 4.0mm

Storage

Heated Bituseal Enamel is to be stored under constant low-speed stirring. Storage temperature and duration depends on the Bituseal grade stored.

Standards

It meets or exceeds all the performance requirements of EN 10300.

Quality Control

All raw materials for Bituseal Enamel are tested and approved in the laboratories of RAHA BITUMEN Co. The quality of the finished enamel is controlled to either EN 10300 or the costumer’s specific requirements and a quality certificate is issued for each batch produced.

Bituseal Coatings

Bituseal Enamel is suitable for pipelines operating at temperatures in the range –30°C to 90°C. The enamel is environmentally safe.

Mechanical Protection

A polypropylene shield can be applied to the Bituseal coated pipe in order to obtain improved mechanical protection of onshore pipelines.

Delivery

Bituseal Enamel is available cold in 20 kg block or hot in bulk.
