Wall Sleeves - Flange to Flange Pipe Connection

Stainless steel wall sleeves - Pipe through wall connections

Wall Sleeves WA.WS-FF units.


Flange to Flange wall sleeves cast in flush with the wall. The flange connection fastens directly to the pipe. ANSI flanges are welded on the sleeve ends for a continuing pipe through the wall.

Puddle flange water stops attach to the sleeve and form an anchoring point for the sleeve. The units cast in a new concrete wall to provide a continuous passage for the pipe system.

Protected Hex nuts, dome nuts, female thread rod or studs on the back of the flanges provide connection fasteners for the connecting pipe.

American and International pipe diameters may be accommodated.


Wall Sleeves WA-WS-FF stainless sleeves are used in WWTP, water treatment facilities, water tanks and other applications to connect pipe through concrete walls.

Diameter range: up to 60 inches (DN 1600)


Stainless steel: 304L-316L, schedule10s or schedule 40 or metric sleeves are available.

Wall Sleeves General

Wall sleeves with flange connection extensions

Wall Sleeves with flange connections: WA-WS.F units, have connection flanges extending out from the wall for connection of continuing pipes through the wall. The sleeve is cast in during wall construction. The pipe system connects to the flange.

wall-sleeve-flange-connectWA-WS.F double flanged joint wall sleeves may be grouted in as a retrofit in an existing wall or cast in a new wall.

Wall sleeves for pipes are available for any wall thickness and pipe diameter.




Wall Sleeves Stainless steel




A continuous transition of the pipeline through the wall is accomplished

The pipe sleeve flange extends out from the wall for the connection and may be a full pipe length or a shorter piece.

Stainless steel, carbon steel, galvanized or corrosion protected marine coatings are available.

Wall Sleeves WA-PF-KS units are custom units with customer defined measures.wall-sleeves-for-large-pipes


WA-PF-KS units cast in wide concrete walls, or are used when large diameter pipe penetrations are required. WA-Modular seal links form watertight sealing of the pipe through the sleeve.

Plain end collars are mounted on each sleeve end. A puddle flange is mounted in the middle of the sleeve.

Wall-Sleeve materials may be stainless steel (304L, 316L or anti corrosion marine coatings. Lengths up to 10 ft. (3000 mm) are available.


Penstock application piping for electrical turbine production use WA-PF-KS flues.

Puddle flanges at the midway point prevent water creep along the outside of the wall sleeves into the structure, flush end flanges form part of the sleeve construction. The end flanges fit inside the wall forms.

WA-modular seal links are designed for larger pipe penetration sealing. WA.GKD modular seal links are an advanced design seal for large pipe projects. They provide high pressure watertight solutions for large diameter pipes through large diameter wall sleeve combinations

Multiple pipes may be sealed through the same sleeve opening using multi port disc seals.

EDPM, NBR or Silicone sealing elements may be selected for sealing the pipe.

Double pipe watertight sealing - Multi pipe watertight sealing


Multi - port openings WA-GP-W models are used when more than one pipe or conduit penetrates through the same sleeve.



Split WA-GP-W sleeves are also available, for existing pipes.


Wall Sleeves WA-ZVR models: are cast in a new concrete wall providing a water and gas tight entry points for pipes, conduit, cords and communication cables.

The special bonding coating create a homogeneous bond with new concrete resulting in a 72 psi (5 bar) passage for pipes and conduit through structure walls.


Cement bonded pipe sleeves, bonds with concrete - providing no leak around solutions. End caps insure a clean passage is maintained until pipes are ready to enter the building.

Pipes / Conduit pass through the sleeve into a structure and are sealed with Modular Seals links, or WA-GP-SR disc seals. The seals are provided as part of the assembly.

Wall sleeves for pipe through walls on an angle to the wall


Wall sleeves WA-APD units provide openings for pipe passage that enter a wall at an angle. Angled ends and puddle flanges are angled to fit perpendicular to the sleeve for an effective watertight pipe entry..

The same approach angle of the pipe is maintained, eliminating additional bends in the pipeline.


Angled pipe wall sleeves may be split units for pipes that already exist or when new concrete walls are built across the pipes.

Pipes sleeves that allow pipe to penetrate a wall at an angle use longer compression bolts and WA-GP disc seals. The seals are 36 psi watertight pipe seals, for pressing water up to 80 ft. head.

Split wall sleeves for existing pipe, are available with either weld closings or bolted closing. They are available for most pipe sizes and accommodate existing piping when new walls or slabs are placed over the pipe.

Sealing elements may be EDPM, NBR or Silicone for heated pipe applications.

Multi-conduit wall penetration sleeve seals, provide wall openings when several conduit cables enter a building in a close cluster. The sleeves may vary in size for different size conduit or pipe or all the same size.

The sleeves are water and gas tight. The penetration are sealed with disc mechanical seals or modular seal links.

The puddle flange collar is cast midway in the wall, the sleeve length is sized for the wall thickness. For conduit penetrations through an existing wall an opening in the wall may be cut to accommodate the size required and the unit grouted in the wall.

There are several combinations of multi-conduit sleeve seals for a best suited sleeve cluster for your project please contact Westatlantic tech Corp.

Wall sleeves for concrete or block walls WA-WS-BW


Block wall pipe sleeves have a fixed flange on the wet side and a loose flange on the inside wall.

The inside flange is loose so it may be fixed to the wall and a silicone seal bead is installed after the loose flange is anchored to the wall.

Both flanges have a EDPM wall gasket.

temporary-building-entry-wall-sleeve WA-WS-BW wall sleeves may be used for pipe passage through the wall or as a opening for temporary conduit, cable or power cords.

When the sleeve is not in use a plug is supplied for closing of the temporary entry.
