Product Description

Alloy C-4 is an austenitic nickel-molybdenum-chromium alloy with a low carbon, silicon, and iron content. This alloy has a significantly lower tendency to form precipitation in the temperature range between 650 and 1,040 °C(1,202 - 1,904 °F), improving its resistance to inter-crystalline corrosion. When machined perfectly, no knife line attack occurs in the heat-affected zones of awelding edge. Alloy C-4 is characterized by: Very good resistance in a broad field of corrosive media, in particular under strongly oxidizing conditions. Excellent resistance to pitting, crevice and stress corrosion.

8-Spectacle Blind Flange, as the name suggests, is shaped like a figure 8, one end of which is a blind plate, the other end is a combination of throttling rings, when conveying fluid, the throttle ring is used, and the blind plate is used when cutting off, a bit like the role of a cut-off valve, which can be used to cut off when the valve leaks. Its sealing performance is better. For systems that require complete isolation, it is generally chosen as a reliable means of isolation. There should be two stop valves before and after the figure 8 blind plate, and when all are closed, replace the state of the figure 8 blind plate. Common heat exchanger operation and backup, reactor operation and backup, nitrogen pipeline and process pipeline connection and so on. Another feature is that it is clearly marked and easy to identify its installation status. The main role played by the eight-figure blind plate is complete partition, just like the role of a gate valve with 100% reliable performance and will not be operated by mistake.
