Why a studded pipe?
1.Increase efficiency in the process of heat recovery and direct flame hostile atmospheres.
2.Reduce the amount of bare pipes used in these processes. (Heat transfer surface of one studded pipe is equivalent to surface of 4 to 10 bare pipes).
3.Ideal for processes applications where dirty fuels are used and harsh environments in terms of temperature and / or corrosion.
Stud Material
1.Carbon steel ASTM A510 grade 1005 to 1010.
2.Alloy steels normally used in steel studs.
3.ASTM A193 Grade: B6, B6X, B8, B8a, B8M, B8C, etc.
4.AISI 304, 316, 410, 347, 321.

Application of studded tubes
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. Studded tubes are two or three times the square of light Tubes. Due to the usage of studded Tubes, the hot strength can be
obtained as the same as radiation in the reasonable design. Studded Tubes manufactured by our company adopt resistance welding method.
Welding process is controlled by PLC program. Feeding motor and graduation use servo motor. Studded number can be set via the human-computer interface. The graduation parameter and compensating coefficient can be set according to technical requirements to ensure the
quality and precision of products.
Production of studded tubes
The steel studs are automatically resistance welded to the tube, producing high quality forge welds. The welding process enables the combination
of any grades for studs and tube: carbon, low 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.
Because of their relative easy of cleaning, studded tubes or nail head 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.
