Description:
Electro-welded Single Wall Steel Tubing
Single wall steel tubing is the most common type of tubing used in household refrigeration applications. Bundy single wall tubing is manufactured by continuously forming a single low carbon steel strip into a tubular shape and welding the adjoining edges using a high frequency induction welding process. Through strict process controls, the internal weld bead is held to a minimum and all external flashing is removed. Corrosion resistant coatings are applied in-line to assure uniform coverage.
Application:
1.AC
2.Refrigeration
3.Heat exchanger
4.Automobile fuel lines,hydraulic brake lines
5.Compressors, etc
