Tube Assemblies

Heated Tube for Vapor Transport

Description of Products

Stainless steel heated tube assemblies from 4” - 18” diameter with tube connection lengths up to 240”. Vacuum jacketing, insulation and heated section options.

These products are used for vapor transport in the distillation of bulk quantities of metal-organic type liquids (TiCl4, SiCl4...etc) where vapor needs to be transported between different containment vessels.

The heated inner tube walls prevent condensation of vapor on the walls. Typical process reaction by-products such as MgCl vapor are transported using heated tube assemblies during the distillation process used to make titanium, silicon based materials and other metals.
