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/T0516-1997 "The technic of design for Insulating flange"
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 insulating
flanges: nominal pressure (PN)”Ü2.5MPa.
1”¢With electrical insulation properties of electro-corrosion pipes;
2”¢With durable and reliable performance at a designed temperature and pressure for pipeline mediums,
sufficient strength and good air-proof ability;
3”¢With rational structure, easy assembly disassembly and replacement.
1”¢Suitable for natural gas, city gas, LPG and gently oil;
2”¢Medium temperature:-10”ę~ + 60”ę;
3”¢Ambient temperature:-20”ę~ + 60”ę;
6”¢Pressure range:PN0.6MPa, PN1.0MPa, PN1.6MPa, PN2.5MPa
7”¢Specs: DN50-DN1200 (2"~48")
