A blind flange is a solid, round plate used to cover or close off the end of a pipe, valve, or vessel. It is commonly used in piping systems where a temporary or permanent closure is required. Blind flanges do not have an opening or a bore and are typically bolted onto the end of the pipe or fitting using bolts or studs. They are mainly used for isolation purposes, maintenance, or to prevent the flow of fluids or gases.
2A14 is a kind of aluminum and aluminum alloy squeezing rod. Because the amount of copper is high, the intensity is high and the thermal strength is better.
