Flexible Pipes TRIZ Cases

A transport element uses overlapping structural layers to dissipate electrostatic charge.

A corrugated pipe embeds an electric cable within its wall thickness at the same level as reinforcement coils to enhance structural flexibility.

Embedded helical reinforcement strips provide kink, crush, and burst resistance without sacrificing hose flexibility or increasing weight.

Optimized carbon black surface area in ethylene-propylene copolymer hoses resolves heat resistance and yarn adhesion trade-offs.

Segmenting the process eliminates tape rupture and residual stresses while enabling resistance to external pressure and rapid gas decompression.

A perforated tube creates a drainage path through pressure armor gaps, removing gases from the annulus without weakening mechanical strength.

A high pressure hose uses a helically wound aramid cable layer to maintain flexibility while increasing strength.

Curved transition surfaces on elongate tapes reduce abrupt strain variations in flexible pipe pressure armour layers.

A ferrule protrusion radially displaces a flexible pressure hose inward to form a constriction.

A hydraulic hose suppresses reinforcing layer corrosion by controlling sulfate ion concentration in the inner tube rubber and woven underlayer.

Flattened braided reinforcement reduces volumetric expansion in long hydraulic brake lines, eliminating time lag between front and rear wheel actuation.

A sixth thermoplastic polymer layer reinforces an irrigation hose structure to enhance burst pressure resistance.

A polyamide resin composition with m-xylylenediamine and aromatic secondary amine compounds.

Silane-grafted polyolefin hoses reduce automotive weight by replacing heavy EPDM rubber with lighter materials and simplified formulations.

Oriented martensitic steel elements reinforce flexible tubular structures to resist hydrogen embrittlement in deepwater environments.

A flexible tube uses an integral conductive inner layer to dissipate electrostatic charges along its length.

A tire tread wear indicator uses contrasting lightness between its contact face and the channel bottom to create a visible signal.

Spirally wound PEEK or polyphenylene sulfide tape welded under tension resists creep and permeation above 130°C.

A multilayer fuel hose uses a harder inner rubber layer to ensure uniform contraction against mating pipes.
