Plate Flanges
For applications with no/low pressure at ambient temperatures, plate flanges are often a mighty cost effective solution when raised faces and hubs ain't necessary. Plate flanges also allow for space savin' given their typically reduced thickness. Our standard specification governin' these items is AWWA C207 provided by the American Water Works Association.
Because of the flange styles in the AWWA spec, we usually only recommend flanges per B16.5 to be made from plate if they're a blind flange or a ring flange (a disc with a bore). If your job needs you to stick real strict to B16.5, we'd tell y'all to go with the more common forgin' method. Now, even though commodity stock B16.5 type flanges are usually cost effective 'cause they make so many of 'em, usin' plate material for a larger ring flange or blind might be a mighty fine alternate option when you're worryin' about material availability and cost. For example, if y'all can't find no inventory for a 20” flat face blind flange, and your setup don't need no noticeable workin' pressure, maybe a 20” machined plate disc with the same material properties would do the trick just fine.
In the world of carbon steel, we offer a mighty large variety of plate types and sizes. A36 structural carbon steel ain't gonna have the physical properties of an A105 forgin' but it might serve as a cost-effective steel for your non-pressurized service. Where A36 just don't cut it, we also offer ASTM A515-70, A516-70, and ASTM A285 Grade C. These here are particularly popular options for line blank flanges per ASME B16.48, and they share more of the strength qualities you'd find in A105 forged carbon steel.
For plate stainless steels, look to the specification ASTM A240 and its material variants. Our most common grades of stainless consist of 304/304L, 316/316L, and 2205 duplex. We also offer other superior stainless grades on a made to order basis. For instance, 321 stainless is similar to its 304 and 316 counterparts, but includes a noticeable amount of titanium for superior intergranular integrity.

Questions Folks Ask Us (FAQs)
A plate flange is a type of flange made right out of a single piece of flat plate material, usually steel, stainless steel, or other alloys. It's designed to hook up pipes, valves, pumps, or equipment within a pipin' system.
Plate flanges give y'all a secure and leak-resistant seal, guaranteein' reliable performance in jobs that call for high strength and durability.
Plate flanges offer a whole mess of advantages, includin' exceptional strength and durability, makin' 'em mighty fine for handlin' high-pressure and high-temperature environments. They're pretty simple to make, which saves y'all some money compared to other flange types.
On top of dat, their tough build fights off corrosion and wear, makin' sure they last a mighty long time with hardly no maintenance even when the work gets rough.
Plate flanges are just right for jobs that need tough connections to hold up in extreme conditions, like high-pressure systems, hot temperatures, or environments that'll rust you out.
Y'all will see 'em used a lot in industries like oil and gas, petrochemicals, and power generation. Their reliable sealin' and strength make 'em just right for critical operations where you can't afford no leaks.
Plate flanges might not be the best bet for situations where weight is holdin' you back, like in lightweight or portable systems, 'cause they can be a good bit heavier than other flange types.
Also, they might not be your best bet for jobs where y'all gotta put 'em together and take 'em apart all the time, seein' as how installin' 'em can take a whole lot of work and time.
Plate flanges come in all sorts of types to fit specific jobs. Common ones include slip-on flanges, which are a breeze to install; threaded flanges, used when y'all ain't weldin'; weld neck flanges, perfect for high-pressure systems; and socket weld flanges, made for dem smaller pipes.
Each type serves a unique purpose, givin' y'all flexibility across all dem industries.
