Wall Sleeves - Through Wall Flange Connection

Connection Continuing Pipe - Flange to Flange at the Wall

Wall Sleeves Flush mount - Stainless steel


WA.WS-FF: flanges mount flush with the concrete wall. ANSI 125/150# slip on flanges are welded to sleeves and protected Hex nuts are welded to the back of the flange to connect the joining pipe to the wall sleeve flange.

All American and International pipe diameters may be accommodated.

Flange to Flange wall sleeves provide a continuous transition through the wall for connecting pipes. Flush flange wall sleeves are cast in during wall construction.

(Flange to Flange Connection)


Wall Sleeves WA-FF stainless wall sleeves are used in WWTP, water treatment facilities, water tanks and other applications.

Diameter range: up to 60 inches (DN 1600)

Wall Sleeves General

Wall Sleeves: WA - WS.F (Flange connection), incoming pipe flanges are bolted to the wall sleeve flange for a continuous transition of the pipeline through the wall.

Wall sleeves are available for any wall thickness and pipe diameter.wall-sleeve-flange-connect



Wall Sleeves Stainless steel





Carbon steel and galvanized wall sleeves also available.


Wall Sleeves WA - multi puddle flange collars for wide concrete walls.



Wall sleeves WA-KS-1 models allow pipe through wall passage for large diameter pipes or for wide concrete wall openings..

Wall-Sleeve materials are stainless steel (304L & 316L), galvanized steel or other materials.


Lengths up to 10ft (3000 mm) are available.

Applications: wall sleeves and ducts for large pipes, penstock flues or wide wall pipe penetrations.

Puddle flanges prevent water creep along the outside of the Wall Sleeves into the structure, end flanges form part of the sleeve.

Pipe passing through the sleeves use modular seals for large diameter pipes. WA-GKD Models are designed for larger pipe penetration sealing. WA.GKD modular seals are an advanced design seal for large pipe projects. They provide high pressure watertight solutions for all large diameter pipes and large diameter wall sleeve combinations. Contact Westatlantic Tech Corp.

Underground tunnels, wind turbine foundation, floor slabs and dam structure are applications where these modular seals are used.

WA-GP compression Seals may be used with a cement bonded wall sleeve when multiple pipes through the same opening is required.

WA - Wall sleeves standard through wall opening forms are manufactured from stainless or steel materials. The standard pipe sleeve is 304L stainless, 12 inch long. Longer lengths are available with higher grades of stainless. Puddle flange collars mounted midway on the sleeve are welded both sides for maximum corrosion resistance, waterproofing and strength.


Wall Sleeves are cast in units sized to form openings for all pipe diameters. They may be stand alone concrete opening solutions for pipe transit into a building and seal with Modular seal links for a complete waterproof pipe entry.

Stainless steel wall sleeves offer greater corrosion resistance.

Integrated puddle flanges, provide water stop and anchoring point features for the sleeve

Wall sleeves for pipe through walls at an incline.


Wall sleeves WA-PD angled models are used when pipe pass through a wall at a structure at an angle. Tapered ends and angled puddle flange are matched angled to fit.

Angled wall sleeves allow pipes to pass through concrete walls on a straight axial line, eliminating additional bends.

Incline pipe sleeves come in split models if pipes already exist.


A GP seal for angled pipe sleeves with long bolt tighteners, creates a 36psi watertight passage - up to 80ft. head of pressure.

For installation, extended bolting make accommodations for the degree of incline.

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 or NBR for hydrocarbon applications and silicone for heated pipes.


External wall sleeve seals model GP-T are fixed to an outside wall.


WA-GP-T split wall sleeves seal a pipe penetration from outside the wall. Leaking link seals from a previous installation are repaired Using a WA-GP-T the pipe remains in service while the leak condition is repaired.
