Product Description

4.76mm*0.7mm  Electro-welded Single Wall Refrigeration Both side copper-coated Steel Bundy Tubing

 

Bundy Tube It covers single-wall, double-wall, copper-brazed steel tubing, zinc-coated steel tubing suitable for general engineering uses, particularly in the automotive, refrigeration, and stove industries for fuel lines, brake lines, oil lines, heating and cooling units, and the like. The tubing is available in either of two types, single strip or double strip. It is delivered in straight length or coil type

 

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 inline to assure uniform coverage.

 

SINGLE WALL STEEL TUBING OD & WT TOLERANCE

4.76mm*0.7mm Copper Pancake Coil , Both Side Copper Coated 4mm Bundy Tube 0

 

All the tube diameters can be available plain, zinc-coated or copper coated.

 

PLAIN TUBE

Plain tube is supplied with its outside surface slightly oiled to improve the resistance to oxidation. The tube shall be kept in dry storages, away from air drafts, humidity or any other corrosive agents

 

ELECTROLYTIC BOTH SIDE COPPER COATING

The steel strip from which the tube is made shall be copper coated on both sides with a copper layer ≥2µm. The area along the welding seam, on the outside surface is not coated because of the scarfing operation to remove the excessive bead.

 

HOT DIP ZINC COATING

Tube outside surface can be coated with a layer of zinc whose weight is ≥ 70 grams per square meter determined by UNI EN ISO 1460/97. This coating the tube withstands to > 72 h in salt spray fog test before showing red rust (according to UNI ISO 9227).
