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
Weld leeg pipe flanges i-attach sa ang pipe sa pamamagitan ng hinang ng pipe sa leeg ng flange pipe. Ang ay nagbibigay-daan para sa paglipat ng stress mula sa hinangin flanges leeg pipe sa pipe mismo. Ito rin ay binabawasan ang mataas na konsentrasyon ng stress sa paanan ng ang hub ng pag-isahin flanges leeg pipe. Weld leeg pipe flanges ay kadalasang ginagamit para sa mataas na presyon ng mga application. Ang loob diameter ng isang maghinang leeg pipe flange ay machined upang tumugma sa loob diameter ng pipe.
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 ay karaniwang naghahatid lamang flanges may flat mukha. Ang uri ng flange ay halos hindi nagbago. Samakatuwid, ang isang
paghahambing ay ginagawa lamang para sa sealing ibabaw. Dahil sa pagbabago ng pagtatalaga ng sealing ibabaw
mga pagkakamali ay maaaring mangyari paminsan-minsan. Ang pagkamagaspang (Rz) ng lumang itinaas mukha form na C at ang bagong isa B1 ay may
an overlapping between 40 to 50 μm. In this roughness window both standards are fulfilled.
Samakatuwid, sa Endress + Hauser flanges ay tinukoy ayon sa parehong mga pamantayan patigasin. Ang double pagmamarka
Ginagawang malinaw na ang parehong mga pamantayan ay nakamit.
