Monolithic Isolation Joint
TOPARTS supplies isolation joints for both onshore and offshore projects. Saving in the overall cost of corrosion control system is just one of the benefits of using isolation joint. The isolation joint comes with an 'O' seal ring for an added safety and strength. The isolation joints are designed to meet and satisfy very high pressure services up to 20,000 psi. Upon request, we can supply monolithic insulation according to your specification.

BENEFITS
ONSHORE PROJECTS

* To limit spread and hence cost of cathodic protection current to those pipes that need to be effectively and economically protected by the main cathodic protection system.

* To isolate a pipeline and to ensure that cathodic protection or stray currents do not cause increased corrosion.

* To electrically "split up" long pipelines into distinctive cathodic protection system.

* To provide protection against earthing currents at domestic and industrial premises where the PME system is in use.

OFFSHORE PROJECTS

* In riser pipes and offshore structures to isolate the pipeline cathodic protection system.

* At fields "tie-ins".

 

 

 

             Special Products supplied include

Barred Tee
Barred Tees of required pressure rating as per parameters for by-pass / branch connection into pipeline. To ensure smooth running of Pigs and avoid any by-pass of kicker products.


Flange Skillets
This tool is designed to hold various size RTJ flange gaskets for the safe and positive insertion between two flange faces without putting the installer in danger and to decrease the time of flange up.


Swivel Ring Flanges
The Swivel-Ring Flange permits 360° rotation of an outer ring around a hub, to allow easy alignment of bolt holes when attaching to a mating standard flange.


Long Weld Neck Flanges
As per customer drawing with cylindrical or spherical radius - centrically or eccentrically placed - with horizontal or beveled, axially displaced weld extrusion, also based on customer demand with close to the final shape forged weld extrusion - taking an optimized grain flow into account.


Anchor Flanges
Anchor/Hanger Flange, supports pipelines and risers. Designed specifically for the application taking in to account external loads.


Spectacle Blinds
Separating one part of a line from another requires a spectacle blind, able to switch from closed to open and back again.


Bleed Rings
Bleed rings are designed for in-line use between flanges or valves to relieve pressure and/or drain fluids. Standard sizes in both RTJ and raised face styles include 1 " through 12 in ANSI ratings from 150# through 1500#.Standard connections are 1/2 " NPT on all bleed rings; 3/4" NPT and socket-weld connections are also available.
