Product Description

EN10139 DC04 8*0.7MM Double wall cold rolled zinc coated steel tubing in coil​

We supply steel tubes of many sizes with fine accuracies, made from low carbon steel strips.

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.

 

Bundy tube, sometimes called Bundy pipe, is type of double-walled low-carbon steel tube manufactured by rolling a copper-coated steel strip through 720 degrees and resistance brazing the overlapped seam in a process called Bundywelding.

 

We offer single wall electro-welded steel tube, also known as single wall Bundy tube. Mostly it's coated with copper for automotive use. Also, it can be plated with zinc for automotive and condenser use, or coated with PVF for automotive use, as an economic alternative for double-wall welded steel tube.

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. 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).
