Valve painted gray, indicating that the body material is stainless steel?

Valve painted gray, indicating that the body material is stainless steel?

Answer:

1, valve products are identified by body material, painted, and its color press tableThe body material of gray cast iron, malleable iron ductile iron blue carbon steel acid resistant steel, stainless alloy steel painted black and silver grey color identification in the blue skyNote: acid resistant steel and stainless steel are not permitted to be painted and copper alloy is not painted.2, in order to express the sealing surface of the valve material, should be in the drive handwheel, handle, board hand to identify the paint, and its color press the provisions of the table. Sealing surface material of copper alloy Babbitt acid resistant stainless steel nitrided steel boronized steel hard alloy Monel alloy plastic rubber cast ironIdentification paint color big red, light yellow, sky blue, sky blue, sky blue, dark yellow, purple, red, green, black(1) the seat and a closure sealing surface material and by coloring materials of low hardness.(2) check valve, painted at the top of the valve cover: safety valve, relief valve, trap painted on the bonnet or bonnet.The paint color of the transmission mechanism shall be as follows:(1) electric device: ordinary type, painted gray, three in one (outdoor, explosion proof, anti-corrosion), painted blue.(2) pneumatic, hydraulic, gear and other drive mechanism, with the coloring products.
2, in order to express the sealing surface of the valve material, should be in the drive handwheel, handle, board hand to identify the paint, and its color press the provisions of the table. Sealing surface material of copper alloy Babbitt acid resistant stainless steel nitrided steel boronized steel hard alloy Monel alloy plastic rubber cast ironIdentification paint color big red, light yellow, sky blue, sky blue, sky blue, dark yellow, purple, red, green, black(1) the seat and a closure sealing surface material and by coloring materials of low hardness.(2) check valve, painted at the top of the valve cover: safety valve, relief valve, trap painted on the bonnet or bonnet.
No, it means carbon steel.Identification coating of valves1, valve products are identified by body material, painted, and its color is in turn:The valve body material cast iron, malleable cast iron ductile iron carbon steel, stainless steel and acid resistant steel alloy steelIdentify paint colors, black, silver, grey, sky blue, medium blueNote: acid resistant steel and stainless steel are not permitted to be painted and copper alloy is not painted.
