http://www.hkforging.net/threaded-flanges/ Introduction Our Ansi B16.5 Class300 Threaded Flanges are similar in appearance to slip-on flanges, but the difference is that they have threads in the bore and can therefore be assembled without welding. They can be welded around the joint after assembly to increase the stability of the link condition. At the same time, these flanges are mainly used to make connections in the smaller bore size range of pipes, reducing turbulence and erosion inside the pipe. Because they are suitable for handling extreme pressures and temperatures and because of this feature are mainly used in petrochemical and refinery plants. Features聽 Because these Ansi B16.5 Class300 Threaded Flanges do not require additional welding work during installation, they are easier to maintain and have sufficient strength compared to normal flanges. They are able to withstand the more rigorous operating conditions and work well in pipe temperatures from -45掳C to 260掳C. In addition, even when they are deformed, the additional torque generated on the pipe is minimal, effectively protecting the pipe and prolonging its life, making them very suitable for connecting high pressure pipes.Threaded Flanges for sale website:http://www.hkforging.net/threaded-flanges/
