Studded Tube Product Description:
The studs are welded to the tubes using electrical resistance welding, producing high quality welds. Studded tubes are mostly employed in preference to finned tubes in heat transfer systems in petrochemical plants, where the surface is exposed to very corrosive environment such as dirty gases or liquids. These tubes should be resistant to aggressive materials and must be cleaned frequently.
Studded Tube(Stainless Steel Welded Tube) Manufacturing Process:
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.
Studded Tube(Welded Stainless Tube) Advantages:
To increase the surface area of the tube and to protect tube surface from direct exposure to heat /corrosive environment.
Studding reduces 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.
Use of studded tubes is ideal for processes/applications, where dirty fuels are used in harsh environments.
Studded Tube(Black Welded Pipe) Properties:
Manufacturing Process:- Electric Resistance Welding
Fin To Tube Bond:- Excellent
Heat Transfer Efficiency:- Excellent
Mechanical Resistance:- Excellent (Hence can be frequently cleaned with high pressure jets unlike other fin tubes. Thereby reducing down time and increasing overall life)
Corrosion Protection:- Gives excellent corrosion protection to the base tube since it entirely covers the base tube (except bare ends).
Temperature Range:- Depending on Properties of material of Fin (Stud) and Pipe
Studded Tube(Weld Galvanized Pipe) Applications：
High density crude oil is passed through studded tubes which are heated from outside. Liquefied product comes out from the other end, which now can be used for further processing.
At times, navy boilers also require studded tubes, with oval shaped studs welded on them. These are used for heating water in water tube boilers.
