Project and accessories

Pipe alone is rarely the whole order. Fittings DIN/EN Ø12–Ø2000 mm, ASME 1/2–60″ (Ø15–Ø1524 mm) – type B, intermediate sizes and fittings to drawing when the standard elbow is not enough. Flanges DIN/EN Ø14–Ø2000 mm, ASME 1/2–60″ (Ø15–Ø1524 mm). Coating, induction bending and finished spool pipes belong to the same line – and the same documentation.
