Single wall Bundy tube for Condenser.
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.
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.

SINGLE WALL STEEL TUBING OD & WT TOLERANCE
All the tube diameters can be available plain, zinc-coated or
copper coated.
PLAIN TUBE
The 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).
