Abstract and Scope of application
- Used for insulations between a new chamber pipe and an existing pipe, and the new chamber pipe and a new pipe for home.
- Used for insulations between a section for the construction of replacing a supplying pipe, a section for the formation of a loop, and an existing supplying pipe without an insulated valve chamber.
- Used for the prevention of a damage to equipments of various kinds which are connected or adjacent to an electrical apparatus.
- Used for the electrical protection of a pipe with may be exposed to a denger of gas explosion due to static electricity and thunderbolt.
- sed when there is provided a condition where is in difficulties for expost facto maintenance and repair, considering a given condition for the construction of an insulation pipe.
Abstract and Scope of application
- It guarantees safety form an impact form the outside and change of temperature on account of it"s strong internal structure. (patent 0538562)
- Sealing of an internal structure adopting an O-Ring of a dual structure is durable even under the worst condition wherein materials for the O-Ring arecharacteristic of strong restitution force(under a condition due to the chang of welding heat and natural temperature at the time of construction)
- By performing F.R.P and EPX Coatting for the outside of a joint for which operation of special insulation is unnecessary after construction, optimal insulation is maintained even at the time of the exposure of the outside and a burying and the strong resistance of an external inpact is exercised to thereby use a product semi-permanently without changes of insulation and structure
IsoJoint
-
IsoJoint is a true monolithic isolating joint which effectively and effciently stops short circuits and stray currents from damaging pipelines and equipment.
IsoJoint employs one or more, preassembled pressure seals and isolating ring, Unlike isolating gasket kits, lsoJoint does net depend on an installer fitting gasket, sleeves and washers into a flange on loaction, Any one of these pates could be damaged causing a complete breakdown of the isolated flange, thus loosiing cathodic isolation. because IsoJoint are welded into place as one piece units, field problems are virtually non-existent and integrity of the isolation is kept intact. -
Furthermore, once installed, IsoJoint can be buried and forgotten ending your maintenance worries.
In contrast,inspections of above ground isolation gaskets are necessary to check for shorts in the gaskets.This requires a continuing maintenace program during the entire life of the pipeline.
BENEFITS & ADVANTAGES
-
In-factory tested hydrostatically and electrically, to 1 1/2 times their working pressure.
Non-destructive testing is also avallable.
No labor intensive, complicated installation procedure required as with isolation gasket kits - No inspection pits, vaults or maintenance needed-weld into place and direct bury-reliable, worry-free cathodic isolation.
- Non-conductive epoxy coatings help prevent shorts,both externally and internally
- Isolates stray currents impressed on the pipe from exterior forces such as electrical transmission systems,earth currents and currents flowing from point to point
- Earthquake resistant -Acts as a thrust block or joint
ADVANTAGE IN SAVINGS
- The notion that flange isolation gasket kits are more cost efficient than monolithis joints is not well supported when figuring in all the variables.
APPLICATIONS
- On gas,oil,liquid pertrochemical and water lines
- Before and from gas distribution stations
