Wall Sleeves General

Flanged Pipe Stainless Steel.


Flanged stainless steel pipe sections 304L, 316L pipes. Diameters 2" to 40", conditioned with non-metallic low pressure cleaning. Polished finish to meet service requirements. 2-20 ft lengths.


Wall Sleeves WA - multi puddle flanges for wide concrete walls.



WA-KS-1 wall sleeves provide pipe through wall transitions for large pipes or for wider concrete walls. Puddle flanges provide added strength, ovality and anchor points.

Materials are stainless steel (304L & 316L), galvanized steel or other materials.


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

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

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

For pipe sealing through the sleeves use large pipe diameters modular seals WA - GKD Models 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.

Applications for: underground tunnels, wind turbine foundation slabs and dam structures.

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 open ends are manufactured from stainless steel materials. The standard pipe sleeve is 304L stainless, 12 inch long. Longer lengths are available with higher grades of stainless. Puddle flanges mounted midway on the sleeve are welded both sides for maximum corrosion resistance, waterproofing and strength.


Cast in Wall Sleeves are sized to form openings for all pipe diameters. They may be stand alone concrete opening solutions for pipeing transit into a building or used with matching Westlatlantic class modular seal for a complete waterproof pipe entry.

Modular seals may be supplied with the wall sleeve assembly to seal the annular space between the pipe and the sleeve.

Stainless steel wall sleeves offer greater corrosion resistance.

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

Wall Sleeves WA-Split - Split Pipe Sleeves for existing pipes

For all American and International pipe sizes

Standard materials 304L

WA-Split pipe sleeves are used when new concrete walls or slabs are placed across existing pipes.

304L stainless split wall sleeves are bolt closed or a weld closed.split-wall-sleeve


Split pipe sleeve models are bolt closed or a weld closed. Standard split sleeve lengths are 12 inch long and sized to accommodate pipe diameters of the existing pipe. Longer sleeves are available.

Two puddle flange collars are standard on the split sleeves. They ship with bolt closing hardware, flange gaskets and pipe seals ready to install.

Weld closing models come with beveled axial splits for welding. Split disk compression seals or modular seal links are supplied with the split sleeve assembly.

When longer sleeve lengths are required, former ribs are placed along the sleeve length for anchoring and to insure wall sleeve ovality.

Wall sleeve diameters are selected that allow annular space seals that are best suited for the modular seal/pipe combination.

Wall sleeves for pipe through walls at an incline.


WA-PD- angled pipe sleeves for walls or floor slabs are used when pipes pass through a concrete structure on an angle. Tapered ends and angled puddle flange waters stops, are matched cut to the pipe entry angle.

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 models. They are available for most pipe sizes and accommodate existing piping, when new walls or slabs are placed.

Sealing elements may be EDPM or NBR for hydrocarbon applications and silicone for heated pipes.

External Wall Mount / Slab mount / Thimble pipe sleeve seals

Bolts to the wall or slab seals to the wall and pipe.



WA GP.T pipe sleeves and seal assembly is designed for external pressure sealing pipes and cables. They may be installed for pipes through manholes, slabs, concrete walls, building foundations or floors.







The assembly is comprised of a sleeve and back plate for fastening to the wall. The back plate is sealed at the wall. A link type annular seal, or disk seal, seals the pipe watertight.

Disk seals are used when more than one pipe is passed though the sleeve. The back plate may be round or square.


A thimble wall sleeve may be split for existing pipes and may be angled to accommodate incline conditions. see samples below.
