Split Casings - Existing Pipeline Protection
Pipe-Conduit-Cable-Protection - Split Ducts
WA-HEX split casings protect existing pipelines. That are not cut pipe sections for rejoining but specific forms.
Bolt closing - No Welding - Install while pipeline is in service
WA-Hex split casings come with gaskets for the axial and butt gaskets. They are sized to fit all American and International pipe sizes in accordance with customer request.
Applications for railroad cross overs, road cross overs. Split casing protection isolate waterlines when sewer and water lines are closer together than the required minimums.
End Flange fittings and mid formers provide stability and strength to the split casing. The design allows for a two man handling for most sizes.
Split Casing ends may be closed or open. Sizing: from 5 inch - 48 inch standard (125mm to 1200mm) larger split casing available on request.
Material: galvanized steel, 304L or 316L stainless steel or carbon steel.
Flange Gaskets: EDPM for water applications or NBR elastomers for oil and gas applications.
Casing Spacers positioners support the pipe in the casing, and are part of the assembly.
WA-Hex (Hexagonal split casing) ships ready to install with all necessary material.
Applications: Gas, oil pipes, conduit runs, communication lines, water sanitary pipes.
WA-Hex split ducts; provide mechanical protection for conduit, power cables and communication lines.
The bottom half placement creates a split channel for the cables and conduits. After placement the top half of the split duct bolts to the bottom half, forming a protective chamber.
Welding is not required, no possibility of heat damage to cables or conduit.
Split ducts help protected power cables from excavation events.
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 may be used.
HDPE casing spacers, gaskets 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.
Basic structures may be modified to accommodate existing field conditions.
Pipeline remains in service
WA.BC split casing pipe.
WA-BC Split casing bolt closing for existing pipeline protection. Where hot welding is prohibited, bolted closing split casings are ideal solutions for gas and oil media pipelines that cross through earth Containment Berms.
Bolt closed split casings provide protection when railways and roadways crossing over existing pipelines.
The half moon sections bolt together with flange to flange bolting points. EDPM or NBR gaskets are provided between the flanges. As part of the assembly, supplied casing spacer positioners hold the carrier pipe off the casing wall. End seals are supplied with the assembly if required.
The end connector flanges and mid pipe forming ribs add strength and stability to the sections. Special casing ends or flange ends may form part of the assembly depending on requirements. Casing ends may be sealed with Modular Seals or compression disk seals.
WA-WC split casing pipes protection for existing pipelines. They ship in 2 m lengths or other cut lengths. Beveled axial and butts provide weld bead reception slots for closing the units around existing carriers. Casing spacers are supplied with the split casing, tey hold the carrier pipe suspended in the casing.
Weld closing split casing may be ordered to protect carrier pipes with large or small diameters. Wall thickness of the split casing is specified by the customer.
Welded split casing may be used for fill-in sections where existing casing protection is already in place. Section lengths required are defined by the customer..
The total run required is obtained by welding the two-meter sections butt to butt. Special protective sheets may be attached to the inner surface of the sections.
Grip hooks may be attached for assist lifting. Normally strap lifting is used as a means of lifting the half moon sections into position.
Installation sequence of welding the bottom sections in place first for several lengths followed by the top sections is normally the process followed. Field conditions may require a different sequence and is a contractor choice.
Steel sections are not corrosion protected but a coating as per customer requirements may be applied in the field after closure procedures are complete. 304lL sections may be ordered as well.
