DELLOK Studded Tube Nailhead Tube For Heat Transfer Boiler

^{Studded Tube Product Description:}

^{Studded Tube are obtained by electric-resistance welding the studs on the external surface of the tube. Such stud welding acting on the entire cross-section of the studs make studded tubes the most robust extended-surfaces tubes which is an important characteristic to consider in particular if severe mechanical loads are expected during service or cleaning.}

^{Studded tubes vary by pattern design, number of rows, space between rows, number of studs in a raw etc. Studs can be find in a large variety of sizes, shapes and materials.The are loaded into the automated electric-welding machine and press welded as the tube is moved longitudinally and circularly following the pattern required. To provide special patterns or for highly customized applications studs are set one by one using a manual electric-welding machine.}

^{Heat exchange efficiency increases dramatically when using studded tubes or pies in comparison to bare surface pipes. Efficiency could increase of 2-3 times and more.}

^{By using studded tubes/ studded pipes it is possible to reduce the amount of bare pipes required for the same heat transfer volume, thus resulting in a more economical solution and lighter weight.}

^{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.}
