What is studded tube?

Studded Pipe also called studded tubes, Studded tubes are a type of metal tubes. These tubes have studs welded onto the metal tube. These studs are arranged in a specific formation throughout the length of the tube. They are often used in boilers and refineries. As they increase the surface area for higher heat transfer they are used for reheating.

Nailhead Pipe or stud Pipe. Studded pipes are used as an alternative to finned tubes in heat exchangers mainly in the petrochemical industry where the surface is exposed to particular corrosion and aggression by gasses and vapors. Studded fin tube is a standard frequency electric-resistance-welded studded type surface. Studded pipe normally weld round carbon steed studs on carbon, alloy or stainless steel tubes with diameters from 1.5" to 12.75".

How to produce studded tube?

Studded pipe is made by electrical resistance stud welding equipment, which specially formed Studs in rows around the tube. The Studs can be supplied in a variety of sizes and shapes. The pattrn in which the studs are arranged on the tube can also be varied by changing the Number of studs per row around the tube, the spacing between the rows, and whether the studs in adjacent Rows are offset. It is also possible to apply studs to just one side of the Tube, or to apply several different Height studs in the same row. The studs are hand loaded into the electrodes and then automatically welded. The welding process alows for the combination of any stud and tube grade, including carbon, aly, stainless sees, and high nickel aloys. After studding, alloy steel pipes are stress -elieved in accordance with the relevant specifications for the steel class

Specification

Studded tube advantages:

Features of a Studded Tube It occupies less space and is, therefore, compact. Highly durable. Preferred over Finned tubes as they act as heat transfer systems.

Application:

Uses of Studded Tubes Steel studded tubes are used instead of finned tubes for heat transfer in the petrochemical industry, generally in furnaces and boilers where the surface is exposed to a very corrosive environment and where very dirty gas streams require frequent or aggressive cleaning.
