Split Casings WA-HEX models protect existing pipelines. Hex split type seals provide watertight seals for the end sections.

Split casings with bolt closing - No Welding - Install while pipeline is in service
WA-Hex split casings come with gaskets for the axial flanges. Hex split casings are sized to fit all American and International pipes in accordance with customer request.

Applications;

Protection for existing pipes where railroad cross overs, road cross overs are constructed. Split casing protect and isolate waterlines when sewer and water lines are closer together than the required minimum distance. Gas, oil pipes, conduit runs, communication lines, water sanitary pipes and utility corridors may be protected.

Rib Flange formers provide stability and strength to the split casing. The design plan allows for a two man handling on 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: are EDPM for water applications or NBR elastomers for oil and gas applications.

Casing Spacer 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.

Split Ducts: Protection for under ground power cables, communication cables and fiber optic cables.

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.

Placement of Split casings

Weld the bottom lengths in place first for several lengths, followed by the top sections. Field conditions may require a different sequence and is a contractor choice.

Normally only expose an existing carrier pipe length so that non-excavated earth supports the pipe. Place split casing lengths under that section length before moving on. Field contractors may modify method of exposing existing carrier pipes to meet other requirements.

WA.BC split casing pipe.

split-casing-pipe-bolt-closing

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.

Install procedures may vary:

Weld the bottom lengths in place first for several lengths, followed by the top sections. Field conditions may require a different sequence and is a contractor choice.

Normally only expose an existing carrier pipe length so that non-excavated earth supports the pipe. Place split casing lengths under that section length before moving on. Field contractors may modify method of exposing existing carrier pipes to meet other requirements.

 


Split Casing pipe - weld closing - Cylindrical Split Casings

split-casing-protect-existing-pipelinesSplit casing pipe welded closing WA-WC model: protect existing pipelines. They ship in 2 m lengths or other cut lengths.

Bevel edges provide weld bead reception slots for closing the units around existing carriers.

A pipeline remains in service during placement of the split casing.

Casing spacers hold the carrier pipe suspended in the casing and are supplied with the split casing.

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.

Weld closed split casing protect large or small diameters carrier pipes. Section lengths and casing type are defined by the customer.

The total run required is obtained by welding lengths together in the field. 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.

Weld the bottom lengths in place first for several lengths, followed by the top sections. Field conditions may require a different sequence and is a contractor choice.

Normally only expose an existing carrier pipe length so that non-excavated earth supports the pipe. Place split casing lengths under that section length before moving on. Field contractors may modify method of exposing existing carrier pipes to meet other requirements.

Non-Metallic casing spacers are normally used for positioning carrier pipes in split casings.

UM eccentric seals may split for existing pipes or non-split when a wrap around is not required.

non-centered-pipe-through-wall-sealing

WA-GP-UM seals do not require the carrier pipe to be centered in the casing

Non-metallic casing spacers have defined leg lengths that can place the carrier pipe below the center postion.

The position of the carrier pipe at the casing end may be sealed by using a eccentric GP-UM seal.

 

It will conform to the carrier pipe exist position. The opening in the GP-UM depends on the height of the casing spacer leg being used.

The plain of the carrier pipe through the casing determines the seal opening center.

E.g. a pipe would be considered to be fully (100%) eccentric it were lying against the inside diameter of the wall sleeve or core hole. A pipe would be said to be concentric (0% eccentric) if it were perfectly centered in the outer pipe or hole.

WA.GP-UM eccentric disk-seals are used to seal - off center carrier pipes.
