What is Stainless Steel Boiler Tube ? What are its functions?
Stainless Steel Boiler Tube is Important Component in Industrial Application Where High Temperatures and Pressures is Required. Its Main Function is Transforms the Heat From Burning Gasses Into Steam or Water. Under High Pressure Its Protect Structural Integrity . As Per Manufacturing Method Boiler Tube is Classified in 2 Types Like Stainless Steel Seamless Boiler Tubes and Welded Boiler Tubes. SS Boiler Tubes Standard OD Range From 1/2 to 12 inches and Wall Thickness From 0.5 to 10 mm.
Stainless Steel Boiler Pipe is Comes in Various Grades, Shapes and Types. Most Common Types are Fire Tube and Stainless Steel Water Tube Boiler. This Tube is Produce Using Various SS Austenitic, Martensitic and Ferritic Group 300 and 400 Series Grades. Boiler Tubing Comes in Round, Square and Rectangular Shape. But Round is Most Common Shape use in Boiler Application
