ASTM A182 Galvanized Threaded/Screwed Flange
We supply ASTM A182 Galvanized Thread Flange , ANSI ASME Threaded Flange,Threaded Pipe Flanges.Our Carbon Steel Flanges are available in various formats such as Slip On, Blind, Weldneck, Socketweld, Threaded, Lap Joint, Orifice, Spectacle Blinds and Long Welded Neck. Carbon steel Flanges are available in sizes from 1/4" to 64" and are manufactured and quality controlled to meet ASME, ASTM, BS and DIN/WERKSTOFFE standards.
Socket Weld Flanges
Socket weld flanges are similar in both dimensions and applications to slip on flanges. The major difference is that socket weld flanges have an internal recess in which the pipe sits. This then gives a better flow of fluid through the piping itself. As a rule, socket weld flanges are more expensive than slip on flanges due to the extra machining required to manufacture them.
Socket weld flanges also tend to be used on smaller pipelines, typically ½"NB to 3"NB for 150lb – 600lb rated flanges and ½"NB to 2.1/2"NB for 1500lb rated flanges.
Lap Joint Flanges
Lap joint flanges or backing flanges are normally used with collars or stub ends. Each Lap Joint Flange usually has a radius machined into the bore identical to that of the stub end or collar so that it can sit directly on it. The stub end or collar is welded on to the pipe leaving the lap joint flange loose behind it. These are then bolted to a similar piping assembly to join the pipeline together. If the pipeline needs to be cleaned or inspected, this kind of flange is perfect for easy dismantling, so that these operations can take place.
Threaded/screwed flanges have a centrally drilled and tapped hole in a variety of thread forms. They are then screwed on to a screwed pipe or fitting – they do not have to be welded to secure them in place. For higher pressure applications, they are sometimes welded to seal and secure them.
Threaded flanges are not suited to applications where heating or stresses are present, as leakage through the threads is possible.
