Monolithic Insulating Joint

aditya steel engg. co. is now offer and manufacture the monolithic insulating joint in Mumbai, India

Monolithic insulating joints (or isolation joints) provide just such protection. Specially designed to be shock absorbent and insulated against electrical charge, they isolate sections of pipeline so that currents can only pass so far.

Monolithic Insulation Joint

Monolith is a large, typically single-standing structure that serves as a prominent sign or marker. These structures are commonly used in various settings to convey important information, promote businesses, or guide individuals. Monolith signage is characterized by its tall and imposing presence, making it easily visible from a distance.

Monolithic insulation joint is a boltless structure that provides electrical resistance between the pipeline sections and adjoining structures, thus improving the effectiveness of the Cathodic Protection System (CP systems).Range Size1 to 48 ClassFrom ANSI 150 to 2500Design Temp Normal Temp-46 C to 95 C.High TempUp to 250 C (On Customer request)Pressure Design PressureAs per ANSI B16.25Test Pressure1.5 times X Design PressureStandard Features Insulating RingASTM D709 G10 TY IVSealsNitile / VitonCoatingEpoxy Resin (Min 200 )ServiceSweet / SourLocationOnshore / OffshoreSuitableBelow / Above GroundMetallic Parts RingsASTM A105, ASTM A694, F42 - F70Pup PiecesAPI 5L GrB, X42-X70, ASTM A106 GrB, ASTM A333 Gr6Electrical Features Di Electric Strength5 KV 50 Hz AC for 1 MinInsulation ResistanceMin 1 Mega Ohm @ 1000V DC StandardsDesign : NACE, ASME Scc VIII, ShellCalculations : As per ASME Sec VIIIWelding Procedure : As per ASME Sec IX, API1104, DNV710105 TestingHydrostatic TestPneumatic TestFatigue TestNDE examinationsElectrical Test:Insulation Resistance Test @ 1000 Volt DCDi Electric Strength Test up to 5000 Volt 50 Hz AC Special TestHelium Leak TestHoliday TestAdhesion TestFlange Displacement Test

Oceaneering s Electrical Isolating Joint (EIJ) isolates the cathodic protection current in a pipeline from other sources that can act as current drains. These current draining sources such as power plants, equipment, steel reinforced concrete and other grounded structures must be isolated in order to achieve and maintain adequate, reliable and economic corrosion control. The EIJ is frequently used offshore to isolate the riser from the jacket structure where a potential difference exists between the two cathodic protection systems. It may also be used to minimize galvanic action between pipelines of dissimilar metals.

Applications Innov Engineering monolithics are designed for applications in the following industries and many more. Iron making Steel Lime Copper Glass Power generation Aluminium lining Petrochemical General furnace Kiln lining Our Range of Monolithics Innov Engineering complete range of monolithics includes low cement, ultra-low cement, plastic, mortals, conventional and insulating castables, acidic ramming mass, and many others for applications in various industries. Our monolithics are highly regarded in the industry because of their quality, excellent performance, value in use, and ability to be cast, gunned, rammed, poured, plastered, pumped and shot-creted.

the cathodically protected structures / surfaces are isolated from the unprotected structures by installing monolithic joints. monolithic insulation joints are superior to insulation kit gasket assemblies. the joints are pre-assembled at the factory and to be welded to the pipelines at site.
