Split Casings - Existing Pipe Protection
Encasement - Existing Pipes - Conduit - Fiber Cables - Power Cables
Hex-Model or Cylindrical Model
Split casings are two separate sections that are bolted together to form an encapsulating protective casing around existing pipes. Applications for pipes under railway extensions, roadway enlargement and other projects requiring encasement of existing pipes.
WA - HEX split casing bolt closed cylindrical
WA - split casing bolt closed Hexagonal
Hexagonal split casings and cylindrical split casings provide encasement protection for existing pipelines.
WA split casings are are manufactured protection casing - not split pipe.
Encasement protection for all American and International pipe sizes.
Casing spacers (positioners) are supplied with the split casing. Casing spacers hold the carrier pipe off the bottom of the split casing.
Reinforcement and end bolting flanges add extra strength to the encasement lengths.
Materials: Galvanized - Corrosion protected steel - Stainless 304L/316L.
Encasement protection for pipes, conduit, power cables and fiber-optic lines. Pipelines remain in service during the install process.
Split Casings for large carrier pipes may be built in sectional diameters WA-HEX-SCBC - Sectional
Split casings models fit all American and International pipe sizes.
Large pipe Hex split casing or cylindrical split casings come with casing spacers steel or non-metallic.

Split casing may be installed by waterworks contractors, specialized equipment is not required.
Split Casing Applications:
- Tank farm protection for existing gas and oil pipes through earth containment berms or bund walls.
- Protection for existing pipelines under rail tracks, roads and other crossover projects.
- Waterline sewer-line cross overs.
- Extra protect for existing pipelines under new building foot prints.
- Protect communication cables and power supply cables.
- Provide utility corridors for service entries.
Rib former collars on the split casing provide stability, and strength. Split Casing ends may be closed or open.
Sizing: from 5 inch - 48 inch standard (125mm to 1200mm) larger split casing available on request.
Split casing Material: galvanized steel, corrosion coated steel, 304L or 316L stainless steel.
Flange Gaskets: EDPM for water applications or NBR elastomer for oil and gas applications.
Casing Spacer "positioners" support the pipe in the casing.
WA-Hex (Hexagonal split casing) ships ready to install with all necessary material.
When installing only expose an existing carrier pipe so that non-excavated earth supports the pipe. Place split casing lengths under that section before moving on.
Basic structures may be modified to accommodate existing field conditions.

Split Casing Round - Bolted joint- Existing pipes
WA.CYL-BCSC split pipe casing.
Pipeline protection for existing pipes, railway and road crossing..
Bolt closed split casings encapsulate and protect existing pipelines. Westatlantic split casings are manafactured to fit the existing pipe outside diameter. They are fabricated in specific section length for flange bolt joining to make up the total length requirement.
Split casing protects existing pipes, power cables and fiber and optic lines. the sections wrap around the pipe and bolt together to form total encasement.
Gaskets may be supplied to fit between the axial and butt end flange joints.
Westatlantic casing spaces (POSITIONERS) hold the carrier pipes off the bottom of the casing. End seals are supplied if required.
End boiling and midpoint flanges add strength and stability to the sections.
Guide to Installing split casings.
- Excavate around existing pipes down to the pipe bedding on both sides of the pipeline.
- The pipe support bedding should be left undisturbed until ready to install a casing spacer around the pipe.
- Remove a portion of support bedding to provide an opening for the casing spacer that wrap around and bolt to the pipe.
- Place the bottom half split casing section under the casing spacers and around the pipe.
- Several bottom half sections may be placed and bolted together.
- For temporary support of the split casing, sand bags or grout may be used.
-
Check with the engineer for minimum supports required for exposed existing pipe.
- Place the top split section over the bottom half and bolt the sections together.
- Grout fill any gap in the original bedding to support the split casing.
-
Grout support may extend to about half way up the split casing.
- Note** the idea here is the new grout bedding will support the split casing, casing spacers support the carrier pipe.
Summary:
- Place the bottom lengths first before top sections.
- Field conditions may require a different placement sequence.
-
Exposed carrier pipe should always be supported.

WA-WC-CYL
Casing spacers with rollers hold the carrier pipe off the bottom of the split casing.
Existing pipelines remain in service during placement of the split casing.
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.
See Non-Metallic casing spacers for bolted split casings.
Split Casing Applications:
Gas Line Industry, Telecommunication Industry, Reusable Cement Forms, Column Covers, Airport Runways, Bridge Construction, Road Construction, Railroad Construction.

End Sealing-Split Casing
Casing End Seals are available in modular link chain, end seal boots, disc seal models and spit end seal boot models.
WA-GP-UM disc eccentric seals:
Do not require the carrier pipe to be centered in the casing. Split models of WA-GP-UM eccentric end seals are available for existing pipes.
Carrier pipes below or above the center position may be sealed. Large annular spaces may be sealed by installing WA-GP- UM seals.
Eccentric pipe seals conform to the carrier pipes exist position. The opening in the GP-UM depends on the height of the casing spacer leg being used.
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 for non-centered pipe through the casing..

Oval casing pipe end seals - watertight
Carrier pipes or casings not round may be sealed with a WA-GP-OVAL end seal.
Out of round end seals are custom fabricated to fit the out of round pipe or casing condition.
Materials: EDPM or NBR elastomer with stainless steel compression plates and hardware.
Measures required for out of round pipe or casing pipe:
Download a measure fill-in sheet:
- Record measures from the carrier pipe OD to the casing Pipe ID - for each point in a 24 hour clock.
- Measures should be perpendicular to the carries pipe.
- Run a straight line from the 6 o'clock to 12 o'clock.
