ASTM A335 P5 P9, Studded Finned Tube ,Steam Reforming Furnace Fin Tube

Studded Pipe also called studded tubes, Nailhead Pipe or stud Pipe, which is made by electrical Resistance welding specially formed Studs in rows around the tube. Studded tubes are used as substitution of finned tubes.

Studded 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.

YUHONG GROUP Studded tube is mainly used in petrochemical and coal chemical industry for tubular heating furnace, convection heat exchanger, air preheater, chemical equipment, heat exchange equipment. To expand the heat transfer area of the light tube by 2 to 3 times, it can improve the heat transfer coefficient of the flue gas side, improve the comprehensive thermal efficiency of the equipment, and is an energy-saving heat transfer element. Its main function is to expand the heat transfer area of the tube and improve the thermal efficiency of the heating furnace.

Our competitive Advantage:

1. We have more than 10,000 square meters workshop, including 6 H-FIN TYPE finning machines, daily extrusion capacity up to 20 tons.
2. The Square of YUHONG Fins H-Finned Tubes are the preferred tube choice for high pressure boilers.
3. Fins can be manufactured by stamping process in almost any shape and size.
4. In-line fin and tube spacing allows for cleaning with excellent choice in sooting or fouling atmospheres.
5. Fin height and spacing are limited only by heat transfer considerations.
6. Fins and tubing can be similar or dissimilar metals
