Because of their relative ease of cleaning, studded tubes and pipes are used in furnaces and fired heaters as an alternative to high frequency welded finned tubes wherever the process application is such that heavy fouling of the external surface may occur.
The studs are attached to the pipe in diametrically opposing pairs around the circumference by electrical resistance welding to ensure a high integrity bond for strength and heat flow.
Stud diameter, height and pitch can be specified on an individual basis.
Welding tests are carried out as a matter of course to ensure the effectiveness of the stud to pipe bond. Heat treatment of completed studded tubes is carried out where necessary. Should fouling eventually reduce the process performance of the equipment, the studded surface can be cleaned efficiently by shot blasting without damage to the materials.
For a rapid quotation please specify:
Tube/Pipe : Diameter, thickness, length and material specification and whether ends are plain or weld prepped.
Studs : Diameter, length or height, number per circumferential row/or circumferential pitch, plus vertical pitch and material specification. Number of rows of studs and plain end lengths.
