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

Bolted Axial Flanges - Bolted Flanged End Connections - Watertight

Pipe protection for existing pipelines from Railroad cross overs, Road cross overs.

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 standard (125mm to 1200mm) larger split casing available on request.

Material may be steel or 304L 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 ships ready to install with all necessary material.

Split casing pipes provide protection for existing, Gas, oil pipes, conduit runs, communication lines, water sanitary 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 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.

Split Casing Pipe Cylindrical Bolt Closing

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

 

Thick wall - split casing pipe bolted closing design. Existing pipeline protection when railways and roadways cross existing pipelines.

Manufactured in cylindrical split sections at 1 and 2 meter lengths. They bolt together flange to flange. EDPM gaskets are provided for flange sealing. Casing spacer positioners hold the carrier pipe off the bottom of the casing and come as part of the assembly.

The end connector flanges and mid pipe forming ribs add strength and stability to the ovality of the sections. Various end designs add versatilely to connector casings, or continuing carrier pipes.

Open ends or custom ends for existing field conditions form part of the assembly. Casing ends may be sealed with Modular Seals or compression disk seals.

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.

Weld close thick-walled pipes are used to protect existing high-pressure gas pipelines or other pipelines that operate under high static and dynamic loads. Thick wall pipes are also used at intersections of pipelines with other underground infrastructure.

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

They are produced in sections 2 m long. The total run required is obtained by welding the two-meter sections butt to butt weld joints. Special protective sheets are attached to the inner surface of the sections, which prevents weld debris from closure procedures from entering the annular space during welding

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

The sections are not corrosion protected but a coating as per customer requirements may be applied in the field after closure procedures are complete.

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