NT9204 Memory Alloy Pipe Connector

Memory Alloy Pipe Connector Description

The Memory Alloy Pipe Connector is a high-performance component designed for aviation hydraulic systems, manufactured from advanced shape memory alloys such as NiTiNb. Its unique material properties enable the connector to undergo martensitic transformation at low temperatures, allowing it to expand and fit over a pipe when cooled in liquid nitrogen, alcohol, or petroleum ether. Upon returning to ambient temperature, the alloy returns to its original shape, generating a significant restoring force that securely clamps the pipe, ensuring a tight and durable connection. This process embeds the inner ridge of the connector into the pipe, forming a metal-to-metal seal that provides exceptional sealing performance and high connection strength. The connector operates reliably under pressures ranging from 13.8 MPa to 55.2 MPa, making it suitable for demanding aerospace environments. Its lightweight construction contributes to overall system efficiency and helps reduce the aircraft's operational weight without compromising structural integrity. The Memory Alloy Pipe Connector also offers excellent corrosion resistance, dimensional stability, and long-term reliability, maintaining its sealing and fastening capabilities over repeated thermal and mechanical cycles. These properties make it an ideal solution for critical hydraulic connections in aircraft, where safety, reliability, and performance are paramount.

1. Manufacturing Process

The manufacturing process of the Memory Alloy Pipe Connector begins with the selection of high-quality shape memory alloys, such as NiTiNb, which are carefully controlled for composition to ensure consistent phase transformation behaviour and mechanical properties. The raw alloy is melted and cast into ingots, then processed through hot forging, rolling, or extrusion to achieve uniform microstructure and precise dimensional tolerances. The pipe connector blanks are machined to exact specifications, forming the inner ridge and outer profile required for secure pipe fitting. Specialized heat treatment processes are applied to set the transformation temperature and recovery force, ensuring the connector can expand in the martensite state and generate sufficient clamping force upon returning to ambient temperature. Surface finishing techniques, including polishing, passivation, and anti-corrosion treatments, are used to enhance durability and environmental resistance. Each connector undergoes rigorous testing for dimensional accuracy, sealing performance, pressure resistance, and mechanical strength to meet aviation safety standards. Finally, the connectors are packaged for storage and delivery, ready for installation without requiring additional coatings or special handling.
