Cooling Tube Assembly

Refrigeration Tube Assembly

• Welded steel pipe / bundy tube / bundy pipe
• Diameter: 3/*6’, 6mm, 1/4’, 5/*6’, 3/8 etc.
• Wall thickness: 0.7±0.*5mm
• Surface treatment: White Zinc, Copper, Yellow Zinc, Olive Green, PVF etc.
• Type: Single wall and double wall
• Application: Single wall used for refrigeration; double wall used for automobile brake system
• Steel pipe, also called seamless welded pipe, is divided into single wall steel pipe and double wall steel pipe, welded by steel plate.
  Single wall steel tubes are mostly used in refrigeration systems;
  Double wall steel tubes are mostly used in automobile brake system.
   Steel pipe surface treatment: surface plating copper, white zinc, colored zinc, PVF and so on, long time rust proof
