DEKOTEC ® -MTS Recommendation for processing ■ All work steps must be performed wearing personal protective equipment such as safety shoes, helmet, protection goggles and welder gloves in accordance with the local occupational health and safety regulations. It is strongly recom- mended to train the personnel inexperienced in the processing of shrink sleeves before the application. ■ Adjacent factory coating must be roughened (e.g. emery cloth #40) and beveled with an angle ≤30°. ■ The use of 2 applicators is recommended for pipe diameters > 400mm (16“). ■ Required surface cleanliness: The surface must be dry, free of grease, oil, dust and other contaminations. Steel surfaces have to be cleaned to a degree of at least St 2 or Sa 2,5 (ISO 8501-1). 1.

DEKOTEC®-MTS
Recommendation for processing
■ All work steps must be performed wearing personal protective equipment such as safety shoes, helmet, protection goggles and welder gloves in accordance with the local occupational health and safety regulations. It is strongly recom-mended to train the personnel inexperienced in the processing of shrink sleeves before the application.
■ Adjacent factory coating must be roughened (e.g. emery cloth #40) and beveled with an angle ≤30°.
■ The use of 2 applicators is recommended for pipe diameters > 400mm (16“).■ Required surface cleanliness: The surface must be dry, free of grease, oil, dust
and other contaminations. Steel surfaces have to be cleaned to a degree of at least St 2 or Sa 2,5 (ISO 8501-1).
