Studded Tube Product Description: The stud pipe or stud tube is used by refining and petrochemical industries for many different applications - including fired heaters and furnaces. It’s also used as an alternative to high frequency welded finned tubes (HF finned tubes). Studs are attached to the pipe around the circumference in completely opposing pairs by means of electrical resistance welding. They are attached to ensure a high integrity bond for strength and heat flow. A bonus of studded pipe is that it’s relatively easy to clean. It’s ideal for applications where heavy fouling of the external surface may occur, or for processes undertaken in harsh environments, where dirty fuels are used. The surface can be efficiently shot blasted (without damaging it). 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. Studded Tube(Fin Tube) Specifications：
