Whether it's a new installation or debottlenecking project, the construction of SPINTUBE bundles increases throughput by up to 40% versus conventional shell and tube exchangers while still allowing the same methods for inspection and cleaning. SPINTUBE also completely eliminates flow induced vibrations.
A SPINTUBE replacement bundle creates additional turbulence and with tubes in direct contact with one another the number of tubes per shell diameter is increased. As a consequence retro-fitting SPINTUBE increases thermal performance in the same shell by up to 40%.
No limitations on tube material and thickness. Tube diameters from 3/8" to 11/4". Tube spin is engineered according to service. Can be cleaned using conventional water-jet methods.
Crude pre-heat trains, cooler trains (amine service), condensers, reboilers and vaporizers, feed-effluent exchangers including horizontal, high pressure units e.g. hydrocrackers, and vertical exchangers e.g. Texas Towers, compressor gas coolers.
Thermal performance improvements up to 40%, improved hydraulic performance (reduced shell-side pressure drop), custom design, minimized project scope, improved efficiency and throughput, vibration problems eliminated, easy cleaning.
The following examples highlight how two refineries were able to improve heat exchanger throughput by retro-fitting with SPINTUBE™.
