Weldable Tube 5-Way Crosses

TFM Weldable Cross Tube Fittings

At TFM, we manufacture high-performance weldable cross tube fittings using premium 304 series stainless steel. These fittings are particularly designed for semiconductor process equipment, making them ideal for roughing lines, foreline, and pump exhaust lines in subfabs.

Features of Our Weldable Crosses

  • Ultra-High Cleanliness for UHV Applications: Our fittings deliver maximum cleanliness, supporting ultra-high vacuum (UHV) applications down to > 10<sup>-13</sup> Torr.
  • Pulled-Port Fabrication: Produced using advanced pulled-port techniques, our weldable crosses feature full penetration butt welds that ensure strength and reliability.
  • Crevice-Free Welds: The design eliminates crevices in weld joints, significantly reducing contamination risks and improving performance in critical environments.
  • Broad Temperature Compatibility: These fittings perform across a wide temperature range, from -200 °C to 450 °C, allowing for versatile use in different operating conditions.
  • Reducer Crosses: Available to accommodate two different tube sizes, providing flexibility for various applications.
  • Custom Sizes Available: We offer standard wall thicknesses and tube diameters, and we are happy to customize solutions based on your specific requirements, including flanged versions.

Specifications

  • Vacuum Range: ≥ 1×10<sup>-13</sup> Torr
  • Temperature Range: -200° to 450° C

For any inquiries or custom requirements, reach out to TFM, where we’re ready to meet your specific project needs.

FAQ

Sputtering targets are materials used in thin-film deposition processes to create coatings on substrates. They are used in industries like semiconductors, optics, photovoltaics, and electronics.

Evaporation materials are used in Physical Vapor Deposition (PVD) processes, where materials are heated and evaporated to form a thin film on a substrate. These are critical for applications in optics, wear protection, and decorative coatings.

Boat crucibles are used as containers for evaporation materials during PVD processes. They help to uniformly evaporate materials onto the substrate for thin film formation.

Sputtering uses energetic particles to eject material from a target, while evaporation involves heating a material until it vaporizes and deposits on a substrate. Both are common methods in Physical Vapor Deposition (PVD) for creating thin films.

Consider the material composition, purity, target size, and application-specific requirements such as the thickness and uniformity of the film.

Yes, we offer customized sputtering targets, evaporation materials, and crucibles to meet specific customer requirements for size, material composition, and purity.

Yes, we can assist in selecting the most suitable material based on your application, whether it’s for optical coatings, semiconductor fabrication, or decorative finishes.

Yes, we offer both bulk and small quantities of sputtering targets, evaporation materials, and spherical powders to support research, prototyping, and development projects.
