Machining according to drawing
We are able to do various types of machining for you, including:
Machining of gasket faces of flanges to a flat face with a finish of Ra = 3.2–12.5 micrometres (= 125–500 microinches AARH) to ASME/ANSI B 16.5a and B 46.1–1985;
Machining of gasket faces of flanges to a finish of Ra = 4.0–6.3 micrometres (= 160–250 microinches AARH) to ANSI/ASME B 46.1–1985.
Machining of partially machined ANSI flanges:
internal drilling of the whole height to ASME/ANSI B 16.5–1988 and B16.5a–1992 to a specified schedule;
machining the gasket face to the required surface roughness to ASME/ANSI B16.5–1988 Table 5;
machining the root/groove face to ASME/ANSI B16.5–1988 Fig.8.
Machining DIN welding neck flanges with extra-strong S-size:
internal drilling of the whole height to a specified wall thickness;
machining the gasket face to a finish of Ra = 3.2–6.3 micrometres (= 125–250 microinches AARH);
machining the root/groove face to DIN 2559 part 1 05-1973 form 22.
A wide range of machining operations in addition to the above are available to order.
