It is well known to us that the flange is trusted for connecting the ends of two pipes together through specified bolts of the welding procedure. It is almost always put on the fields of the choke, tee, valve and other equipment. Actually, the flange is designed in line with the specific requirements with the shapes of rectangular, square and round and others to accommodate the various needs and projects. Now, some main types are briefly introduced in the next.

It ought to be mentioned that the most popular kind of ruthless pipe flange is commonly the weld neck flange. Through MS Flanges , the flange is able to bear the high pressure and temperature in the working environment. Similarly, the kind called the socket welding flange can also withstand high pressure. What else, it really is generally applicable for the small piping and would ensure the unfettered flow of the flow because the result of being specially designed. And the threaded pipe flange may be the one not connecting through welding but additionally safely found in high pressured regions of projects and machinery.

For the connecting with bolts, the blind flangewith round bolt holed is popular to seal of blank off the ends of valves and pipes. Similarly, the slip-on flange can be popular in the industrial for the benefits of being low priced and dependable at preventing leaks. It withstands the liquids beneath the working environment of low pressure. Unlike this kind, the atmosphere for the lap joint flange is that it's used for junctures that do not are exposed to anything flowing through the pipes. Therefore, the durability would increase comparing to other types. And when constant changes in pipe diameters to support changing conditions in a few piping system, the reducing flange would do great favors with the characteristics of connects different types and sizes of flanges.

At present, the methods to connecting two flanges are limited just with welding or bolt. And the material for the flange manufacturing is bound, either. With the proceeding modern industry, designers or manufacturers had endeavor themselves into producing much more specified flanges to reach the increasing requirements. There is no doubt, with the advanced technologies. It really is promising for the future of the flange.
