Description:

Serrated Tubes For Oil Refinery

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.

Uses Of Studded TubesSealing Technology & Engineering Products Manufacturing

Steel studded tubes are used instead of finned tubes for heat transfer in the processing industries, generally in furnaces, gas turbines, fired heaters and furnace applictions where the surface is exposed to a very corrosive environment and where very dirty gas streams require frequent or aggressive cleaning

Welding process

The steel studs are automatically resistance welded to the tube, producing high quality forge welds. Our automatic studding machines are capable of handling tube diameters from 1" TO 8" o/d and standard stud diameter of 12.7mm.

The welding process enables the combination of any grades for studs and tube: carbon, alloy, stainless steels and high nickel alloys. Alloy steel pipes are stress-relieved after studding, according to the relevant specifications for the class and grade of steel used.
