According to different insulation seals of flange, insulation flange is classified into pressure seal insulation flange and self-sealing insulation flange. Among the two kinds of insulation flange, application scope of pressure seal type insulation flange is: the nominal pressure Pn acuities were 2.5 MPa. Insulation flange is a joint name for pipe flange joint that both has the sealing performance required by buried steel pipeline and electric insulation performance required by the electrical method corrosion protection engineering at the same time. It includes a pair of steel flanges, insulation seals between two flanges, flange fasteners and fastening insulation parts and a pair of short steel tubes that have been welded with two pieces of flanges respectively.


Insulation flange as well as the insulation joint is produced for industry like petroleum, chemical, etc. It has simple structure and reliable performance and it is safe to use, as a result, it is popular and has been widely applied. Insulation flange products have been formed series, when in special circumstances, can be designed and manufactured according to users’ requirements separately.


Features of insulation flange:

Has the required electrical insulating performance by buried pipeline electrical method corrosion protection engineering.
Work reliably under the temperature and pressure required by media of the pipeline for a long time, having enough strength and sealing performance.

Reasonable-structured, convenient to assemble, disassemble and replace parts.
