1.Know Your API6A From Your ANSI b16.5


The use of duplex and super duplexstainless steel in pipes and pipe flanges is popular, because of the extra strength these materials provide.

If you're in the business of buying pipes or pipe fittings, you'll appreciate the importance of getting materials right in flanges, and buying the right ones for what you need.

Because there are so many different kinds of flange across the world, there are global standards to make life easier, from api 6ato ansi b16.5.

With so many different pipe flanges around, from weld neck flanges to blind flanges and api flanges, it's worth understanding the differences between them all, and what the different standards mean.


Ansi B16.5

The ansi designations include ansi b16.5, which covers pressure-temperature ratings, materials, dimensions, tolerances, marking, testing, and methods of designating openings for pipe flangesand flanged fittings.

The ansi b16.5 designation is unique, and not interchangeable with a flange of a different classification.

2.Know more about kinds of flanges

Weld Neck Flanges

Weld neck flanges are the most popular type of high pressure pipe flange The tapered hub design of weld neck flangesprovides an extremely strong connection and weld neck flanges can be repeatedly manipulated and bent without compromising the material and or connection quality. Weld neck flangesalso have the advantage of being highly resistant to extreme high and low temperatures.

Blind Flanges

Blind flangesare often used to seal or blank off the ends of valves and pipes. Blind flanges are always round and have bolt holes around their perimeter. And blind flangesare also known for being very economical.

API Flanges

API flangesare manufactured for high strength operating refinery systems with products such as oil and explosive gases. API flanges are also made with a higher operating pressure, which sets them apart from say an ansi b16.5 flange.

Within api flanges, there are further categories, such as api 6a.

Pipe Flanges

Whether you're after blind flangesor need an api 6a, make us at Citizen Metals Pvt. Ltd. your first port of call. We have a wide range of api flangesin stock, and can supply all of them with grooves, back faces, bevels and bores inlaid with a variety of alloys.
