Products decription :
Special technology for electrical insulation for trouble-free
operation of oil pipelines, insulating joint
Specifications
Insulation joint is an indispensable important pipeline accessory
in gas transmission and distribution and petroleum pipeline
systems. It is mainly used in gas transmission and distribution
systems and gas pressure regulating stations. The pipelines are
insulated from each other to protect them from electrochemical
corrosion and prolong their service life. They can also be buried
directly in the ground.
Monolithic Insulating joint
Size: 1''-120'',
CL150, CL200, CL300, CL400, CL600, CL900, CL1500, CL2500
Standard: GB150-2011 or ASME B 31.8 or ASME B 31.4/31.3
Installation place: Aboveground or underground
Business Type: Manufacturer
Introduction:
Insulating joint (Isolating Joint) is the key component in Cathodic
Protection (CP) System. It is mainly used in underground gas
transition and distribution system including gas reducing station,
each section of gas transition and distribution pipeline, also the
part between gas reducing station and the pipeline, which increase
the life of the plant and equipment by reducing or eliminating the
electric and chemical corrosion damage.

Standard Testing:
* Hydrostatic test: 1.5 times MOP (Max. Operation Pressure).
* Electrical Resistance: >= 20Mohm @ 1000v DC under dry air at
25 oC
* Dielectrical voltage: >= 3.5kv AC 50Hz (1 minute) (Can be 5kv
as per request)
Ordering Information:
Please specify the following requirement:
* Pipeline Diameter, Grade of pipe, wall thickness of pipe;
* ANSI rating
* Medium to be transported in pipeline and temperature of
transported medium
* Additional Testing required except standard testing: X-ray,
ultrasonic & magnetic testing, etc.
Features
Good insulation performance: The insulation resistance is 10MΩ,
which improves the service life of the protected pipeline.
Long life: same life and same strength as the pipeline;
High strength: The secondary sealing structure is used, and the
polymer composite material is injected into the annular space
between the two flanges.
Buried installation: Observation wells are not necessary for
underground installation, but can be buried directly underground;
