A digital electronic system assumes control and monitoring functions for the motor. This accessory ensures a gentle start-up, and prevents motor overheating and unintentional start-ups after a voltage drop.

The UKC 3-R fillet weld grinder is suited to working on hard-to-access fillet welds – a problem zone often encountered on vessels and railings around tubes. It is based on a 500W motor, and has a speed range of 1,400-3,300 rpm. This high torque is strong enough to provide the optimal drive for modern high-performance abrasives. The motor is characterised by a high power density in a small volume. The stator winding is protected with additional insulation from abrasive grinding dust, to prevent motor

The fillet weld grinder weighs only 1.8kg. For minimised tool weight and optimised manoeuvrability, a very low long-neck angled head was developed, made

Metal-removal machine tools, facilities for heat treatment and NDT allow the company to produce centrifugally cast tubes and articles at the level of worldwide standards. Around 60% of products are exported. The quality

The company’s plant can produce fittings in the diameter range 24 to 1,420mm: elbows, bends, tees, pipe crosses and reducers of carbon- and alloyed steels. Some of these products are supplied to thermal power stations and atomic power stations. Thanks to the possibility of independent manufacture of moulding tools, new standard sizes of fitting are constantly mastered.

Production capacity of liquid metal is greater than 20,000 tons per year: seamless centrifugally cast tubes of OD range from 100 to 1,625mm, wall thickness from 7 to 250mm, length up to 6,250mm, in more than 200 grades of steel, alloys, cast iron, bi-metallic combinations, as machined, heat-
