Insulating flange is a generic term of pipe flange joints with requirements in sealing performance of buried steel pipes and electrical insulation properties of electro-corrosion pipes. It include a pair of steel flanges, an insulating and sealing article between two flanges with each end welded.The insulating flanges are specially designed and produced for petroleum, chemical and other industries related by us. With their simple structures, safe operations and reliable performance, they have always enjoyed eat popularity among all customers. These insulating flanges have already matured and in case of any special equirements, they may be customized upon all customer's demands. USAGE: Insulating flanges are mainly applied to gas transmission pipelines, gas regulators, gauges, storages etc. With their main functions to separate and insulate different segments of?gas transmission pipes, devices and lines, protect them form any chemical corrosion and prolong their service life. Follow the standard SY/T0516-2008 "The technic of design for Insulated flange" CATEGORY: These products may be classified into two groups by the insulating sealing parts, which are specific- pressure sealed insulating flanges (for short, I-type insulating flanges) and self-tightening seal insulating flanges (for short, II-type insulating flanges). Scope of application of the I-type insulation flanges: nominal pressure.class150 2500 FEATURES: 1With electrical insulation properties of electro-corrosion pipes; 2With durable and reliable performance at a designed temperature and pressure for pipeline mediums, sufficient strength and good air-proof ability; 3With rational structure, easy assembly disassembly and replacement.
