Top Hat Forgings (as indicated above) are one of our more regular produced components manufactured and machined for the
double block and bleed valve manufacturer.
Based in the Steel City of Sheffield, we have the ability to tap into the vast wealth of Sub-contract Machining Engineers which
have been synonymous with Sheffield for the last 150 – 200 years.
Centrifugally Spun Castings
The centrifugal process creates a very tight and defined grain structure due to the management of directional solidification of molten metal under high pressure. Dies are rotated at very high speeds, creating a centrifugal force which throws the dense, liquid metal to the outside diameter, where it cools against the die wall from the outside in. Less dense impurities ‘float’ to the bore and are subsequently removed during proof machining.
Centrifugally cast solutions for heat, wear and corrosion susceptible environments.
Balls. Rings, Tubes and Bushes. Seal Components. Column Pipes and Rising Mains.
