A comprehensive fittings range...

Brownall's range of Brazoweld tube fittings is designed to braze or bronze weld to copper tube and presents the services engineer with a comprehensive range of fittings and flanges which will meet all normal requirements in copper tube installations.

Material and application

The Brazoweld range of pipe fittings and flanges are cast in high quality brazing metal alloy CC760S to BS EN 1982:1999 (which offers a high resistance to dezincification). All fittings have uniform internal contours with easy sweeps and tapered reductions to ensure minimum resistance to flow. Socket ends of all fittings are machined to suitable capillary tolerances, to suit copper alloy tube to BS EN 1057:1996, with chamfers to facilitate brazing or welding. The size of the socket ended fittings range from 15-159mm. A tube stop abutment is also provided. Designed for ease of installation; all fittings are neat and streamlined in appearance.

Flanges and screwed fittings

Also available as part of the Brownall range are brazing metal, two-piece and screwed gunmetal flanges. The flanges can be manufactured to suit a wide range of flange tables including BS Table 10, BS 4504 and ASA 150 & 300.Brownall Female Screwed Fitting

Another integral part of the Brownall range is the wide selection of screwed gunmetal and brass pipe fittings. These fittings are manufactured with accurately machined British Standard pipe and American Standard taper pipe threads. Sizes range from 1/8" to 4". All unmachined surfaces are shot blasted, and each fitting is hydraulically tested to the double standard working pressure of 10 bar (150 lbf/sq in) steam or gas; 14 bar (200 lbf/sq in) water.

Brownall offer a strong, user friendly and corrosion resistant range of fittings and flanges. The range has been specified for several decades by professional building services, consulting engineers and specifying authorities because it offers long-term, trouble-free and reliable service.
