flange face of flat face, riased face and RTJ face
There are different types of flange faces, such as Flat Face (FF), Raised Face (RF), Lap Joint, Ring Type Joint (RTJ), Male and Female types, and Tongue and groove (T&G). Among them, FF, RF and RTJ faces are regularly used in piping. Flat face flanges are used when the counter flange has a flat face. This condition occurs mainly in connection to Cast Iron equipment, valves, and specialties. Full face non-metallic gasket is used when a flat face flange is used. This type of flange not used in high pressure and temperature application. Raised face flange has a small portion around the bore that is raised from the face. The gasket seat on this raised face. The height of the raised face depends on the flange pressure-temperature rating that is known as a class of the flange. This type of flange is used in high pressure and temperature application. Ring joint type face flange has a specially designed grove in which metal gasket seat. This type of flange is used in very high pressure and temperature services.

Alloy steel WN Flange with ISO certificate
Alloy steel WN Flange with ISO certificate Weld neck pipe flanges attach to the pipe by welding the pipe to the neck of the pipe flange. This allows for the transfer of stress from the weld neck pipe flanges to the pipe itself. This also reduces high stress concentration at the base of the hub of the weld neck pipe flanges. Weld neck pipe flanges are often used for high pressure applications.

Flat welding flange sealing surface can be made smooth, bump and mortise three. Smooth flat welding flange the largest number of applications, and more for medium conditions more modest circumstances, such as low pressure non-purified compressed air, low pressure circulating water, which has the advantage of cheaper prices. Butt Weld Flange: It is used for the counter welding of flange and pipe. Its structure is reasonable, its strength and degree of steel are large, it can withstand high temperature and high pressure, rep

Long welding neck RF forging flange A105N
Long welding neck RF forging flange A105N Long and high neck flange: The neck height is higher, which improves the rigidity and carrying capacity of the flange. Compared with butt-welded flanges, the welding workload is large, the welding rod consumption is high, and it can not withstand high temperature and pressure, repeated bending and temperature fluctuations, but it is more convenient for on-site installation and can omit the process of welding seam scratching, which is more popular.

SPECTACLE BLIND RF CLASS 150 FLANGE
As the name implies, the Bazi Blind plate is shaped like a figure eight. One end is a blind plate, and the other end is composed of a throttle ring. When fluid is transported, the throttle ring is used, and the blind plate is used when cutting off. It is a bit like a shut-off valve. Function, it can be used to cut off when the valve leaks. Its sealing performance is relatively good. For systems that require complete isolation, they are generally selected as reliable isolation means. There should be two shut-off valves at the front and back of the figure-eight blind. When all of them are in the closed state, change the state of the figure-eight blind. A spectacle blind is a safety device used to isolate a section of line or piece of equipment when the line or equipment needs to be inspected or removed from service. It is different than a valve in that the blind is a permanent or long term isolation device.

Slip On RF Flange B16.5 ASTM F304/F304L
A loose flange refers to a flange loosely fitted on the flange of a container or pipeline. It is a loose flange. The flange can be made by flanging, direct turning out, or another welding ring. The advantage is that no additional torque is generated to the container or pipeline when the flange is deformed, and it is convenient to manufacture. It can be made of materials different from the container or pipeline, which is convenient for saving precious metals. The disadvantage is that the flange thickness is large. Suitable for occasions where the vessel or pipeline is lined with brittle materials and the pressure is not high. Slip on pipe flanges actually slip over the pipe. These pipe flanges are typically machined with an inside diameter slightly larger than the outside diameter of the pipe. 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.

Carbon steel threaded flange
Threaded flange is a kind of non-welded flange by processing the inner hole of the flange into pipe thread and matching with the threaded pipe to realize the connection. Compared with flat welding flange or butt welding flange, threaded flange has the characteristics of convenient installation and maintenance. Threaded flanges are attached to the pipe like any other screwed fittings, and may be back-welded to seal the joint between pipe and flange. Although still available in most sizes and pressure ratings, screwed fittings today are used almost exclusively in smaller pipe sizes and at low pressures.

B16.47 RF CLASS 600 LAP JIONT
A Lap Joint Flange is usually used in conjunction with Lap Joint Stubs. Lap Joint Flanges in carbon or low alloy steel piping systems are best used when frequent dismantling for inspection and cleaning is required. The use of Lap Joint Flanges at points where severe bending stress occurs should be avoided.
