About Finewel d Tube. . .

Fineweld ® Tube is one of the many product lines of Olin Brass. Our markets include power utility, desalination, air conditioning & refrigeration, architectural hardware, and plumbing. We specialize in applications demanding superior surface quality, and in the copper-nickel alloys for heat transfer applications. We manufacture welded copper alloy tubing via the high-frequency induced current manufacturing method. The flat-rolled strip that we use in the production of our tube is supplied exclusively from Olin Brass. Olin Brass, our parent company, was founded in East Alton, Illinois in 1918 by Franklin Olin. The company was created for the purpose of supplying brass strip to Western Cartridge, now Winchester-Western, for use in small caliber ammunition being supplied to the allied forces during World War 1.

Fineweld ® Tube is a product of the Olin Brass Metals Research Laboratory. Commercialized in 1968, we have since achieved a position of leadership in the manufacturing of high-frequency welded copper alloy tubing.

Heating, Cooling & Refrigeration Applications in this end-use category include absorption air conditioners, ground-source and water source heat pumps, swimming pool heaters, and commercial refrigeration units. The alloy typically supplied for these applications is 90/10 Copper-Nickel (C706). “Low Fin” integral fin tubing, sometimes used in these applications, is produced in accordance with ASME SB-956. Our tubing can also be used in headers and connection tube for commercial air conditioning. Significant cost savings can be realized through the use of Alloy C194, an iron-modified Copper.

Alloys supplied for these applications include 90/10 Copper-Nickel, 85/15 Copper-Nickel, 80/20 Copper-Nickel, 70/30 Copper-Nickel, Admiralty Brass, Aluminum Brass, Iron-Modified Copper, Phosphorus Deoxidized Copper, and Red Brass.

Architectural & Decorative Tubing supplied by Fineweld ® Tube is forge-welded from flat-rolled strip supplied by Olin Brass, our parent company. Tubing produced by this manufacturing process is ideal for “surface critical” applications including stair & hand railing, luggage carts, crowd control posts, coat racks, bar rail, brass beds, and musical instruments. The uniform wall thickness associated with welded tube is also beneficial for subsequent customer operations such as thread cutting. Alloys produced for these applications include Commercial Bronze (C220), Red Brass (C230), Low Brass (C240), Cartridge Brass (C260), Yellow Brass (C268),18% Nickel-Silver (C752), and 10% Nickel-Silver (C745).

Patterned tube, as well as polished & clear-coated or satin-finished tube can also be supplied. Plumbing & Plumbing Hardware Our tubing is widely used in plumbing & plumbing hardware applications where the final product is buffed and plated, or just plated. This is because of the excellent surface quality associated with welded tube. The uniform wall thickness of welded tube also makes it desirable for applications which involve thread cutting. Applications include round and shaped faucet spouts, tail pieces, shower arms, and trap tube. Typically, cartridge brass (C260) or yellow brass (C268) is specified for these applications. All tubing is produced in accordance with ASTM B-587.

Strip Manufacturing

Large Ingots

Olin Brass Fineweld ® Tube is produced from flat-rolled strip which is roll-formed into a tubular shape and then welded. The manufacturing process begins with “Direct Chill” semi-continuous casting to produce metallurgically homogeneous cast bars. Laminations and inclusions are essentially non-existent in the input strip, and therefore in the welded tube that is made from that strip. Casting lots consist of 60,000 pounds resulting in greater uniformity from one tube to another. Following the casting operation, bars of metal are hot-rolled down to a thickness of about 0.600 ”(15 mm) and then the top and bottom surfaces are mechanically

Metallurgically Sound Strip

milled to remove surface discontinuities that might result from casting. Since one of these surfaces will ultimately be the ID of a tube, the possibility of a casting defect being present on the ID of a welded tube is essentially eliminated. Following the milling operation, bars of metal (now in coil form) are alternately cold-rolled and annealed until the desired final thickness is achieved. As a result of this process, the wall thickness in a welded tube is much more uniform than is possible with the competitive seamless manufacturing process. This is a benefit in subsequent operations such as thread-cutting or the rolling of tubes into tubesheets.

Strip

At Fineweld ® Tube, we use the high-frequency welding method. With this process, high-frequency current (450 kilohertz) is concentrated at the edges of the strip metal which is being welded. Virtually instantaneous heat creates an essentially “plastic” condition at the strip edges with the rest of the tube remaining relatively cool. Simultaneously, the strip edges are brought together with forging pressure

High-Speed Forming and Welding

provided by squeeze-rolls, thereby producing a high-quality forge weld. Excess metal, expelled during the forge-welding process, is continuously removed from both the inside and outside surfaces. Finally, one continuous operation precision cuts the tube length, deburrs the ends, cleans the inside diameter, and delivers the tubes for packing.

Testing and Inspection

Our quality system is ISO 9001:2000 certified. All tubes are 100% eddy current tested. The eddy current test coil is located in-line just after the tube is welded. This assures that every inch of tube is tested and avoids “end effects” associated with off-line eddy current testing. Tubes are also visually and dimensionally inspected throughout the manufacturing process.

On-Line Eddy Current Testing

Destructive tests are conducted in accordance with applicable ASTM or ASME Specifications, and include expansion testing, flattening, and reverse flattening testing. Overall tube integrity, and weld integrity, are critically evaluated with these tests. Hydrostatic and pneumatic testing capabilities are also available, upon request.

Mag. 50X Before Annealing

The high-frequency welding process produces a narrow, hot wrought “forge-weld” structure of exceptional quality. The photomicrograph on the top left is for a typical weld produced by this process. Note the narrow homogeneous structure of the weld. The width of the weld is uniform from top to bottom indicating that the heat energy input was uniform. Since a high-frequency induction weld is a wrought structure similar to the parent material, and since no filler metals are used, the strength, ductility, and corrosion resisting characteristics of the weld are similar to the parent material.

The photomicrograph on the middle left indicates that after annealing, the “forge-weld” area is undiscernible from the rest of the tube.

The true test of a product is how it performs in demanding applications. Shown below are several applications in which Fineweld ® Tube welded tubing is used that demonstrate the superior weld integrity of our product.
