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 BS4504:1989 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 BS4504:1969 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 BS10 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 10:2009

BS 10 carbon steel flanges have a long history with the first appearance being 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.

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.
