1. Slip-on pipe flanges
Slip-on pipe flanges actually slip over the pipe. These pipe flanges are typically machined with an inside diameter of the pipe flange slightly larger than the outside diameter of the pipe. This allows the flange to slide over the pipe but to still have a somewhat snug fit. Slip-on pipe flanges are secured to the pipe with a fillet weld at the top and the bottom of the slip-on pipe flanges. These pipe flanges are also further categorized as a ring or a hub
2. Weld neck pipe flanges
Saldatura flange collo attribuiscono al tubo mediante saldatura del tubo al collo della flangia del tubo. Il permette il trasferimento di stress dalle flange collo saldatura al tubo stesso. Ciò riduce anche la concentrazione elevata sollecitazione alla base del mozzo delle flange collo saldatura. Saldatura flange collo sono spesso utilizzati per applicazioni ad alta pressione. Il diametro interno di un tubo flangia a saldare viene lavorata per corrispondere al diametro interno del tubo.
3. Blind pipe flanges
Blind pipe flanges are pipe flanges used to seal the end of a piping system or pressure vessel openings to prevent flow. Blind pipe flanges are commonly used for pressure testing the flow of liquid or gas through a pipe or vessel. Blind pipe flanges also allow easy access to the pipe in the event that work must be done inside the line. Blind pipe flanges are often used for high pressure applications. Slip on Pipe flanges with a hub have published specifications that range from 1/2" thru 96".
4. Threaded pipe flanges
Threaded pipe flanges are similar to slip-on pipe flanges except the bore of threaded pipe flange has tapered threads. Threaded pipe flanges are used with pipes that have external threads. The benefit of these pipe flanges is that it can be attached without welding. Threaded pipe flanges are often used for small diameter, high pressure requirements. Slip on Pipe flanges with a hub have published specifications that range from 1/2" thru 24".
5. Socket-weld pipe flanges
Socket-weld pipe flanges are typically used on smaller sizes of high pressure pipes. These pipe flanges are attached by inserting the pipe into the socket end and applying fillet weld around the top. This allows for a smooth bore and better flow of the fluid or gas inside of the pipe. Slip on Pipe flanges with a hub have published specifications that range from 1/2" thru 24".
Endress + Hauser solito fornisce esclusivamente flange con faccia piatta. Questo tipo di flangia non è cambiata. Così, un
confronto viene fatto solo per questo superfici di tenuta. A causa del cambiamento della designazione della superficie di tenuta
gli errori si possono verificare di tanto in tanto. La rugosità (Rz) del vecchio sollevata modulo frontale C e la nuova B1 hanno
an overlapping between 40 to 50 μm. In this roughness window both standards are fulfilled.
Pertanto, a Endress + Hauser le flange sono specificati secondo entrambi gli standard della flangia. Questa marcatura doppia
rende chiaro che entrambe le norme siano rispettate.
