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)≤2.5MPa.
FEATURES:
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.
MAINLY SPECIFICATION:
1,Suitable for natural gas, city gas, LPG and gently oil;
2,Medium temperature:-10℃~ + 60℃;
3,Ambient temperature:-20℃~ + 60℃;
4,Insulating resistance:≥500KΩ;
5,Breakdown voltage:≥3KV;
6,Pressure range:PN0.6MPa, PN1.0MPa, PN1.6MPa, PN2.5MPa
7,Specs: DN50-DN1200 (2"~48") |
