Welded Fittings

Welded Fittings

Weld fittings are commonly used in vacuum roughing lines on semiconductor process equipment and for forelines and pump exhaust lines in semiconductor subfabs. All tees and crosses are fabricated with the pulled-port technique and full penetration butt welds. This provides crevice-free weld joints and the maximum in cleanliness for UHV applications.

Weld fittings are available from stock in 304 stainless steel, and some sizes are stocked in 316L stainless steel for additional corrosion resistance. All weld fittings are available with various flange combinations.
