Hydraulic Pit Props
The photograph shows several of these components, each of which measures 1.5m (5 feet) long by 15.24cm (6 inches) in diameter. They have been sprayed with a deposit of S2 with a finish thickness ranging from 0.4mm (0.016”) to 1mm (0.040”). The new surface offers the advantages of reduced friction and greater wear resistance. The photograph shows the components before finishing; the work was carried out using a Metallisation Arc Spray system.
