The following designs are available from ABB's standard range of thermowells. However, many organizations have their own standard designs and these can be accommodated by selecting 'other design' and providing a drawing for quotation.
The document describes the ABB TSW400 series of thermowells, engineered to international standards specifically for the Oil & Gas industry. These devices are characterized as being safe, tough, and reliable, with manufacturing options that include full material control and welding certifications.
Available designs cover various mounting styles such as flanged (welded or forged) and weld-in/threaded configurations. The thermowells come in three basic profiles: straight, tapered, and stepped, with specific attention to dimensions like immersion length, external length, and tip diameter.
The standard tip thickness is 6 mm.
The standard stem-to-flange radius measures 3 mm.
