Ring Type Joint Raised Face Flange Rtj Kiah Metallurgy Our alloy metallic ring type joint flanges are at massive synthetic by using an internal diameter of the pipe flange which is pretty much better than the outside diameter of the pipe reasonably. these duplex metallic ring kind joint flanges are linked, usually inside and outside, to offer greater strength and also to prevent leakage in pipes. The main function of these hastelloy alloy socket weld raised face flanges is to offer an access point to a pipeline for metering fluids or gases. socket weld raised face flanges (swrf flange) specification. dimensions: ansi b16.5, ansi b16.47 series a & b, mss sp44, asa, api 605, awwa, custom drawings. size: 1 2″ (15 nb) to 48″ (1200nb.
Ring Type Joint Raised Face Flanges Rtj Super Duplex Steel Blind raised face flanges (blrf) weld neck raised face flange; slip on raised face flanges (sorf) orifice flanges; socket weld raised face flanges (swrf) lap joint flanges; ring type joint raised face flange (rtj) spectacle blind flanges; round bars. hex bars; flat bars; square bars; round bars; bright bars; bright bar; pipes & tubes. seamless. Like other flanges, they use a gasket under compression to create a secure joint. but an rtj flange differs from the more common flat and raised face flange in several ways: the gasket used is a steel ring – instead of the flat composite material type. an rtj flange has a groove machined into the flange surface to accept the gasket. Asme b31.1 says that when connecting flat face cast iron flanges to carbon steel flanges, the raised face on the carbon steel flange must be removed, and that a full face gasket is required. this is to keep the thin, bittle cast iron flange from being sprung into the gap caused by the raised face of the carbon steel flange. ring type joint (rtj). Raised face – rf flange. raised face flange has a small portion around the bore raised from the face. the gasket seat on this raised face. the height of the raised face depends on the flange pressure temperature rating, known as a flange class. for 150# & 300# height of the raised face is 1 16”, and above 300#, it is 1 4”.
Ring Type Joint Flange Asme B16 5 Carbon Steel Raised Face Rtj Flange Asme b31.1 says that when connecting flat face cast iron flanges to carbon steel flanges, the raised face on the carbon steel flange must be removed, and that a full face gasket is required. this is to keep the thin, bittle cast iron flange from being sprung into the gap caused by the raised face of the carbon steel flange. ring type joint (rtj). Raised face – rf flange. raised face flange has a small portion around the bore raised from the face. the gasket seat on this raised face. the height of the raised face depends on the flange pressure temperature rating, known as a flange class. for 150# & 300# height of the raised face is 1 16”, and above 300#, it is 1 4”. The asme b16.5 rtj flanges refers to pipe flanges manufactured in accordance with asme b16.5 furnished with a ring type joint facing. the ring type joint facing, also known simply as ring joint facing, is an additional raised portion furnished to various flange types to form a one piece flange. a deep ring shaped groove shall be cut into the. Metal (hard) gaskets are used with rtj flanges, while raised face gaskets use soft or semi metal gaskets. there are three main groups of ring type joints: r, rx and bx; we will focus on the type r joint because it is by far the most common. rtj type r gaskets are circular in shape with an oval or octagonal shaped profile body; the octagonal.
