Sigma-Netics, a global manufacturer of pressure switches, pressure transducers, metal bellows, and metal bellows assemblies, has recently announced the addition of precision, thin-walled metal tubes to its product offering. These tubes are designed for use in sensor systems, biomedical components, defense applications, and other industrial and precision uses that require high performance and reliability.
The new tubes are made from various metal materials, including stainless steel, Monel, beryllium-copper, brass, and bronze alloys. They are available as completely open or closed at one end, depending on the customer’s specifications. They can also be customized with axial ribs and other special shapes, created through hydroforming, to suit different applications.
Using advanced tooling and manufacturing techniques, Sigma-Netics can achieve precision tolerances as low as 0.004 inch (in.) on the tube diameters, as well as tighter tolerances ranging from 0.00015 to 0.0005 in. on the wall thickness. These tubes also feature a seamless design and a smooth, homogenous surface, compared to welded tubes, which enhances their durability and resistance to corrosion, fatigue, and stress.
The table below summarizes some of the key features and specifications of the new tubes:
| Feature | Specification |
|---|---|
| Maximum length | 17.72 in. |
| Diameter | 0.196 to 2.75 in. with a range of precision tolerances from 0.004 to 0.015 in. |
| Wall thickness | 0.0025 to 0.020 in. with a range of precision tolerances from 0.00015 to 0.0005 in. |
| Closed-end design | Optional |
| Special shapes | Available through hydroforming |
| Hardness | Supplied in hard or fully annealed conditions |
The new tubes are suitable for many applications that require high precision, strength, and flexibility, such as:
- Medical devices: The tubes can be used for catheters, stents, needles, implants, and other devices that need to be inserted into the human body or deliver fluids or drugs.
- Plug connections: The tubes can be used for electrical or optical connectors that need to withstand harsh environments and vibrations.
- Liquid distribution: The tubes can be used for fluid handling systems that need to transport liquids or gases under high pressure or temperature.
- Sensor housings: The tubes can be used for protecting sensors or transducers that need to operate in submersible or underwater applications.
- Defense applications: The tubes can be used for precision bullet jackets and mortar ammunition that need to have consistent accuracy and performance.
