Split Casings - Existing Pipeline Protection







Bolt closing - No Welding - Install while pipeline is in service

Split Casing pipes protect existing pipelines when new Railroads, Roads are built across existing pipes.

Rib flange end formers and mid formers provide stability and strength to the split casing. The design allows two man handling for most sizes.

Split Casing ends may be sealed or left open.

Sizing: from 5 inch - 48 inch (125mm to 1200mm)

Material may be galvanized steel (4 mm to 8 mm WT) or 304 stainless steel (3 mm to 6 mm WT).

EDPM seals: are used for water applications or NBR elastomers seals for oil and gas applications.

Positioners (Casing Spacers) support the pipe in the casing, and are part of the assembly.

Hexagonal split casing ship ready to install with all necessary material.

Split casing pipes provide protection for existing, gas mains, oil pipelines, conduit runs, communication lines, water main and sanitary line protection.split-casing-installation-protect-existing-pipes






Split casing pipes may be installed for secondary protection systems, where existing oil pipelines cross over waterways. Split casings may be installed at fuel storage facilities, Airports and Marine docks, when new crossover roadways are built.

Split Ducts

Under ground power cable protection Heavy Duty Split Ducts


Westatlantic split ducts; provide mechanical protection for conduit, power cables and communication lines.

The bottom half creates a split channel for the cable placement of cables and conduits.


After placenment the top half of the split duct bolts to the bottom half, forming a protective chamber for the cables and conduit.

EDPM gaskets provide a watertight seal between the flanges.

Welding is not required, no possibility of heat damage to cables or conduit.

Buried power lines using Westatlantic split ducts are protected from events above ground.

Non-metallic wheel insulators position and protect the carrier conduit or cable bundles. Axial movement of the power cable and conduit is possible.

Split duct systems are placed by open cut trenching. The steel ducts provide added mechanical protection for power, gas and communication lines.

Multiple conduit pipe or cable wires may be strapped and placed in the ducts. For under water conduit runs, 316L material casings provide mechanical protection for communication lines and power cables.

HDPE casing spacers, and bolting are supplied as part of the split assembly. Split duct materials may be galvanized steel, 304L and 316L steel. End sealing for multiple conduit or power cables are supplied with the assembly if required.

Pipelines that run close together may require a custom design for fitting purposes. Basic structures may be modified to accommodate existing field conditions.

Cylindrical Split Casing

Bolt closing - No welding - Install while pipeline is in service

WA.TW split model bolt closing.


Split Casing Pipe Cylindrical Bolt Closing

16 inch - 60 inch (400 - 1500mm) Diameter
Wall thickness 8mm - 22 mm


Thick wall split casing pipe with bolted closings, protect existing pipelines where high static and dynamic loads are present.

Manufactured in cylindrical half-moon sections and 2 meter lengths they bolt butt to butt for the length of the run.

Forming ribs add extra strength and maintain ovality for the casing. Butt flange joint connector ribs insure a continuous run for the total length of the casing. Various end designs add versatilely to connector casings.

End designs are fitted for coupling connectors, open ends or custom ends for existing field conditions. Casing ends may be sealed with Modular Mechanical Elastomeric Seals or compression disk seals.


Split Casing pipe - weld closings - thick wall.split-casing-weld-joint-closing-with-weld-liner-protection



Welded axial and butt joint split pipe casing

16 inch - 60 inch (400 - 1500mm) Diameter
Wall thickness 8mm - 22 mm





Split casing pipes for high static and dynamic loads, protect existing high pressure gas pipelines or other pressure pipelines.

Diameters available 16 inch - 60 inch (400 – 1500 mm), in wall thickness from 8 – 22 mm. Standard length is 2 m (6 1/2 ft.). Shorter pieces are also available.

High load pressure split casings may be used when a pipe intersect with other underground infrastructure.

Sections are welded together on site to form the total run length.

The inside surface of the casing pipe is covered with metal sheet that protects the pipeline from welding procedures.

Lifting grip hooks may be remove after the units are welded in place. Mounting brackets are removed after the split casing is weld closed.


For split casing sizing and pricing, provide pipe OD and length required.
