ASTM A254 SPCC Lowe Carbon Copper Coated Steel Bundy Tube
Our 4.76mm x 0.65 in rolls copper plated Bundy tubes conform to the ASTM A254-97 Standard Specification. It can be used for fuel lines, brake lines, oil lines of Automotive uses, cooling units of refrigeration uses and stove industries. etc. It is made by rolling steel strips into the form of tubing and subsequently copper brazing in a reducing atmosphere. After a variety of analyses, like heat analysis and product analysis, and through tension tensile strength, flattening, expansion, bending and pressure-proof test to ensure the quality.
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
All the tube diameters can be available plain, zinc-coated or copper coated.
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).
