Tuyer Pipe

Yash Engineering tuyeres have been designed for high-performance in your AOD vessel. Our calibrated design reduces the rapid increase in flow at a set shroud pressure as the tuyeres decrease in length with lining wear. The Fabrication Engineering tuyere will provide the same flow at full length as standard tuyeres but controls the rapid increase in ow after given pressure as the tuyere wears to provide more uniform shroud cooling gas flow distribution in multiple tuyere vessels. A sturdy outer wall coupling piece provides rm support to lock the tuyere into the vessel shell. This heavy wall provides a good sur face for a strong, secure connection between the tuyere and the vessel to help assure reliable inservice operation. The inner tube is swaged over a mandrel to provide a uniform diameter for metering the process gas. Swaging holds the diameter to very close tolerances (±0.002 in or better) for the precise metering required to assure good process control and high-quality product. The outer tube is made from 304 stainless, providing high-temperature strength. The stainless steel tube is welded to the nut, which is threaded into the heavy wall coupling and seal welded for joint integrity. The assembly is mandrel sized to ±0.002 in for precision shroud metering. When you choose Yash Engineering tuyeres, you are assured the design will be consistent with our latest developments in AOD process technology. Special designs are available to suit customers needs.
