wire on tube condenser for refrigerator

Raw material

  Rolling welded steel tube: ? 4.76 ∼ ? 6.35 ×0.71 ,  Low carbon steel wire O.D1.4 ∼ 1.6mm  Bracket: steel plate(SPCC) thickness 0.6 ∼ 2.0Steel plate : SPCC thickness 0.6 ∼ 0.8

Structure

  Flat type of wire on tube condenser used at the back;  Bended or spiral type of wire on tube condenser used at the bottom;  Wrapped type of tube embed on plate

Key process

Tube Bending, Welding, Fix the bracket, Weld the suction tube, Leakage test, Cleaning, Coating, (Folding or bending to shape), Inspection, Packing

Technical standards

Wire pitch ≥ 5 Can produce according to the drawing or sample supplied by clients, also can help the clients design and produce different condensers.

Performance
