Pipes TRIZ Cases

Snap-fit sleeve caps with ridges and channels speed concrete drain sleeve adjustment, protect the diaphragm, and support heavy fittings.

A spherical fitting and adjustable retainer let an escutcheon sit flush on walls or ceilings even when the supply pipe exits at an angle.

A sealed aqueous gel and inorganic fiber layer delays heat rise, reduces fiber exposure, and simplifies reusable fire protection for raceways.

Overmolded tubing is built into a composite vehicle component to eliminate fasteners, cut assembly time, and maintain a secure leak-proof conduit.

Demand-based hot water recirculation cuts cold-water waste, detects leaks, and helps control Legionella in existing plumbing.

A profiled flange body improves feed-through stability during casting while increasing seal overlap for tighter wall, floor, and ceiling installation.

A V-shaped seal land limits heat conduction to polymer seal elements, preserving annular gap sealing in high-temperature aircraft nacelles.

A hinged fold-out collar pulls a fire-resistant cap across pipe penetrations, enabling reliable retrofit sealing in confined wall spaces.

A silicone rubber insulation layer with zinc borate and expandable graphite lets aerospace hoses withstand zero-flow fire without an external sleeve.

Heat-reduction insulation shields the sealing element so a firestop collar stays water- and gas-tight after fire exposure without long sleeves.

A threaded compression ring and screw-in fitting are pressed, then welded or soldered, to seal corrugated metal pipes against leakage, vibration, and corrosion.

A flexible collar seal around wall vents and pipes blocks moisture and air leakage while simplifying installation beyond caulking.

A positioning-debris cover holds valve orientation during wall-box installation while blocking debris and accidental actuation.

Water-activated PVA-SAP knitted seals swell into gel to self-fill cracks and joints without drilling, staying effective under joint movement.

Slanted conduit inlets and ribbed sealing plugs cut insertion force and plug damage while preserving reliable pipe sealing under pressure.

A decoupled seal sleeve uses hose-clamp radial compression to simplify cable entry sealing while handling varied line diameters and angles.

Aligned layered blowing agents direct firestop expansion into passage openings, improving closure while reducing lateral material loss.

Mechanical engagement sections replace welding in duct ferrules to resist thermal stress, prevent cracking, and extend service life.

Separable collars and a slip fitting let one adapter match varying outlet depths while keeping plumbing fixtures flush, sealed, and quick to install.

Pivoting wedge seals on parallel drain tubes close nacelle drain mast gaps, accommodate compression distortion, and prevent fluid leaks.

A nested internal connector fixes fluid treatment modules on a pipe without reducing fabric-soil contact or disturbing the surrounding soil.

A single overmolded port joins tubing through the bore to simplify aseptic connections, cut failure points, and lower connection cost.

A concrete-entrained intumescent ring lets one deck sleeve assembly block fire and smoke for metal and plastic penetrants with less material.

A threaded fastener locks a wall-mounted tap flange in one wall opening, avoiding extra screw holes and reducing loosening on uneven walls.

Mechanical compression of pipe, ring, and wall gaskets creates a liquid-tight sump seal without adhesives, improving chemical resistance and service life.

A flexible insert lets the escutcheon pass over an existing compression ferrule, preserving a small pipe gap and avoiding ferrule removal tools.

A clamping adapter mounts a lead-through and coupling on single gypsum wall panels while reducing holes, stress concentration, and moisture barrier damage.

Movable bearing points let pipes be aligned at building openings while reducing structure-borne sound and preserving fire protection.

A spherical fitting and adjustable retainer let an escutcheon mount flush on walls or ceilings when supply pipes exit at non-90-degree angles.

Upper and lower seals around a valve rod sleeve block moisture and debris, preventing ice build-up in subsurface cold-weather access holes.

Push-to-release pipe joints and a right-angle pipe layout enable quick water or gas appliance hookup while keeping the wall surface flush.

A slit retainer with a spring plate and spherical bearing simplifies firewall seal assembly while sealing moving pass-through members.

An elastic annular profile seal extends into the wall to keep pipe penetrations watertight even when pipe overhang is short.

An interior-inserted elastic sealing duct closes facade fluid openings without scaffolding while maintaining air and water tightness.

Interlocking slots and deflectable tabs let one fire collar fit different pipe diameters while intumescent material seals wall and ceiling penetrations.
