Insulating flange production process

A major component of the insulating flange is as follows:
Flange; 2, bolts insulating sleeve, 3, internal insulation pads; 4, nuts, bolts; bolt insulation pads; 6, anti-corrosion coating. 7, short steel tube;
Second, the insulating flange assembly details:
1, flange. Flange made of 20 # high-quality carbon structural steel, the blank flange forging as a whole.hydraulic banjo fittings
2, bolt insulating sleeve; bolt casing with PTFE.
3, the internal insulation pads. The insulating gasket material is neoprene rubber phenolic resin veneer.
4 studs, nuts. The insulating flange with studs, nuts 35CrMoA low-alloy steel.
5, bolt insulation pads; PTFE gasket material.
6, anti-corrosion coating. Flange and a short section of the inner and outer surfaces of steel corrosion epoxy powder electrostatic spraying process; steel inner and outer wall and the groove from the steel short section end 200mm zinc silicate shop primer corrosion.
7, steel short tube. Short steel tube by Q235C carbon structural killed steel hot rolling steel plate from the system.metric hydraulic hose fittings
