Insulating parts in the pipeline medium should meet the chemical stability and corrosion resistance
Insulating parts in the pipeline medium should meet the chemical stability and corrosion resistance, and should not be in the manufacturing and planning of the use of the life of the seizure can be visualized function change.
Used to process the insulating ring, insulating gasket insulating board material in addition to the rules of GBT1303 .4 should be in line with the rules of Table 1.
The minimum thickness of insulating rings and insulating seals should be determined according to the operating conditions of insulated joints, insulated flanges and the strength of insulating sealing materials. Nominal diameter greater than or equal to DN100 insulated joints, insulating flanges, insulating rings and insulating seals used thickness should not be less than 12mm; nominal diameter less than DN100 insulated joints, insulating flanges, insulating rings and insulating seals used thickness should not be less than 6mm.
When the planning pressure is greater than or equal to 6.3MPa, it is appropriate to choose the epoxy layer of jade glass cloth board production of insulation ring; when the planning pressure is greater than or equal to 4. OMPa and the requirements of the air tightness test, need to do the insulating ring to increase the degree of its internal density of the treatment, the internal density of the insulating ring should be along the touch of the pipeline medium has been processed along the appearance of the treatment.
