Insulated flanges are mainly used at the inlet and outlet of equipment in oil and gas transmission and distribution systems. Their main function is to insulate and isolate each section of the oil and gas transmission and distribution pipeline, as well as between the oil and gas equipment and the transmission and distribution pipeline, protecting them from chemical corrosion and extending their service life. The product complies with the SY/T0516-1997 "Technical Regulations for Design of Insulation Flanges" standard.
