Fluid Pressure Sealed Joints TRIZ Cases
- Wide-Range Pipe Fitting With Rotating Grip Teeth for Low-Torque Sealing
Rotating grip-band teeth adapt to varying pipe diameters and materials, creating a tight seal and pull-out resistance with lower torque.
- Tubular Expansion Joint Sealing for Low-Pressure Transport
An O-ring sled and sliding pads replace packing in tubular expansion joints to cut leakage and maintenance in low-pressure transport.
- Hose Plug Connector Pressing With Free-Deformation Monitoring
A narrowed connector section lets the hose deform before clamping, enabling dimension detection and consistent press-fit quality.
- Flexible Pipe End-Fitting Sealing for Pressure Reversals
Line-contact sealing rings eliminate permanent compressive loading while keeping flexible pipe end-fittings leak-tight under pressure reversals.
- Cryogenic Pipe Connection Sealing With Pressure Equalization
A venting channel with a check valve relieves expanding cryogenic gas in the secondary seal chamber to prevent seal damage and leakage.
- Metallic Pipe Connection Geometry for Uniform O-Ring Compression
Inclined annular walls and a V-shaped profile enable uniform O-ring compression, lower residual stress, and reliable pipe sealing.
- Fluid Conduit Coupling With Reduced-Taper Threads and Retained Seals
Reduced-taper threads and collar-retained interchangeable seals help prevent overtightening breakage and extend fluid conduit coupling life.
- Portable Gas Flow Meter Verification With Adjustable Pipeline Connections
A portable reference meter with adjustable piping and adapter flanges verifies in-field gas flow meters without interrupting pipeline operation.
- Large-Diameter Quick Connect Coupling With Spring-Loaded Sealing
A spring-loaded ring uses internal pressure to seal large quick connect couplings by hand while limiting nipple damage and maintaining flow.
