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/T0516-1997 "The technic of design for Insulating 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 insulating

flanges: nominal pressure (PN)ӆ2.5MPa.

FEATURES:

1ӢWith electrical insulation properties of electro-corrosion pipes;

2ӢWith durable and reliable performance at a designed temperature and pressure for pipeline mediums,

sufficient strength and good air-proof ability;

3ӢWith rational structure, easy assembly disassembly and replacement.

MAINLY SPECIFICATION:

1ӢSuitable for natural gas, city gas, LPG and gently oil;

2”¢Medium temperature:-10”ę~ + 60”ę;

3”¢Ambient temperature:-20”ę~ + 60”ę;

4”¢Insulating resistance:”Ż500K¦ø;

5”¢Breakdown voltage:”Ż3KV;

6ӢPressure range:PN0.6MPa, PN1.0MPa, PN1.6MPa, PN2.5MPa

7ӢSpecs: DN50-DN1200 (2"~48")
