TFM Weldable Cross Tube Fittings
At TFM, we manufacture weldable cross tube fittings using 304 series stainless steel, tailored for the demanding requirements of semiconductor process equipment. These weld fittings are ideal for roughing lines, as well as foreline and pump exhaust lines, commonly found in semiconductor subfabs.
Key Features of Our Weldable Crosses
- High Cleanliness for UHV Applications: Designed for ultra-high vacuum (UHV) systems, providing cleanliness levels down to > 10<sup>-13</sup> Torr.
- Precision Fabrication: Made using the pulled-port technique with full penetration butt welds, ensuring high structural integrity and performance.
- Crevice-Free Weld Joints: Engineered for contamination-free operation, with crevice-free joints for enhanced reliability.
- Wide Temperature Range: Operates effectively between -200 °C to 450 °C, suitable for a variety of thermal environments.
- Reducer Crosses Available: Adaptable to connect tubes of two different sizes, offering versatility in system design.
- Customizable Options: While standard wall thicknesses and tube diameters are available, we can customize fittings based on your specifications. Flanged versions are also available upon request.
