Carbon Steel Flanges BS EN 1092-1:2013

This range of flanges is better known as metric flanges and was previously designated as flanges to BS 4504:1989 and first appeared in 1969. They were meant to replace the BS 10 range of carbon steel flanges but so far this has not happened as the older imperial range of flanges is still in use today.

Flanges to BS EN 1092-1:2013 came into being with decimalisation at the end of the 1960s under BS 4504:1969 although in my experience didn’t come into what we would call normal use until the early 1980s as many businesses still had factories and pipe systems full of BS 10 flanges and many valve manufacturers still produced great quantities of valves with imperial flanges and charged more for the metric versions of the same product.

I believe it took all of the 1970s before the industry started to embrace the new metric specifications that we now consider the norm and some even longer than that. Whatever flanges your business requires though we can offer the product from our warehouses in Ashton-under-Lyne, contact us to discuss your requirements.

Carbon Steel Flanges BS 10:2009A BS 10 Mild steel slip-o welding plate flange

BS 10 Carbon steel flanges have a long history with the first appearance being in 1926 which would have come from the British Engineering Standards Association the predecessor of the British Standards Institute. Even though this range of carbon steel flanges has been around for the best part of 90 years they are still in regular use and the current standard was updated in 2009. Here at Besseges (Valves, Tubes & Fittings) Ltd we can offer these flanges from stock in plate, slip-on bossed, screwed and drilled and galvanised screwed and drilled. Sizes available start at 15mm (1/2”) nominal bore to 150mm (6”) nominal bore in threaded flanges right up to 300mm (12”) in welded flanges.

Larger sizes can be purchased by contacting our sales team. BS 10:2009 carbon steel flanges are categorised in letter form and the most commonly used are Table D, Table E, Table F and Table H, each letter denotes a maximum pressure at a specified temperature, this information can be found online by visiting the BSI where this and many other British Standards can be purchased. We can also offer less common flanges in tables J, K, R, S and T, please contact us for more information.

Carbon Steel Flanges ASME B16.5:2013

This range of American standard carbon steel flanges have been known and are known as ASA flanges, ANSI flanges and ASME flanges and I believe the original specification ASA was adopted by API the American Petroleum Institute in the late 1930s. These flanges are used and specified across the globe for chemical and petrochemical applications including the United Kingdom. Our stock range for this carbon steel flanges product range is limited to 150lb and 300lb flanges although we can offer flanges with much higher pressure ratings as per your requirements.
