Ceramic Flange Plate

Mingrui ceramics specializes in the production of ceramic insulation flange, ceramic flange, ceramic insulation flange, ceramic disc;The maximum outer diameter of the ceramic flange can be more than 200mm. The ceramic flange has the advantages of bonding, wear resistance, high temperature resistance and so on.

Flanges are the parts connected between pipes and are used for connecting pipe ends.Flanges are also used at the inlet and outlet of the equipment to connect the two devices.Flange connection is an important way of pipe construction connection, flange connection is easy to use, can withstand greater pressure, in a boiler room or production site, flange connection of pipes and equipment everywhere.

Manufacturing precision:

Ceramic Flange plate precision machining dimension can be up to plus or minus 0.001mm, the minimum pore diameter can be machined 0.07mm, the minimum tolerance of inner hole can be machined 0.005mm. High precision, high surface smoothness.
