Steel flanges represent connecting elements of flat, ring or disk form with a number of holes required for the fixture. Steel flanges are mounted using bolts and studs that can tightly connect the piping and pipe fittings. Such equipment can withstand almost any pressure, but the flanges for pipes should be regularly pull in order to avoid reducing leakage.
Stainless flanges help connect a number of pieces of pipes without worrying about the possible occurrence of leaks in bond areas. Steel flanges require regular monitoring, which allows maintaining the efficiency of the pipeline system at a decent and secure level. In this case one can be fully confident that the tightness at the level of the network will be preserved and the flange will perform its function properly.
Manufacture of flanges: basic classification
Nowadays it is customary to use the popular classification of flanges that implies dividing them into the flat, threaded and сollar. Flat steel flanges can be attached to the back surface of the pipes. That is why some of the flanges have a larger inner diameter than the outer diameter of the pipe. By choosing this kind of connecting equipment, an engineer should take into account not only the values of nominal pressure, but also the resistance to operating temperature and the transport medium.
Neck flanges are mainly designed to be welded to the butt joint of the pipe. Thus, the magnitude of the inner diameter of the connecting equipment remains completely identical to the diameter of the pipe. With the ability to provide high levels of integrity and reliability in the joint, stainless steel flange is commonly used in modern communications systems (in turn, threaded flanges are typically not used in laying piping).
Steel flanges – the specifics of operation
The average lifespan of flanges manufactured under a complete set of pipelines depends on the quality of their production. Thus, making a choice in favor of a decent vendor is essential to guarantee long years of trouble-free operation. By cooperating with AlexanderComley production facilities, servicing a good number of industries and producing a wide array of flanges and tube plates, you can be sure that the piping system equipped with sturdy stainless steel flanges will effectively serve you faithfully without costly maintenance for years to come. From custom options to standard API/ANSI solutions, there is a rich variety of products to choose from, just drop in at the website’s gallery to have a look.
Flanges for pipes are primarily designed for operation in temperatures ranging from -253°C to +600° C, while steel flanges withstand temperatures from -70 ° C to 450°C.
AlexanderComely experts confirm the fact that steel butt weld fittings uk have a considerable advantage: they are relatively easy to install, that’s why they are massively used when performing repairs. In addition, stainless flanges can be used in hard to reach areas of pipeline systems, especially the ones servicing toxic or flammable materials. It is also important to note that planar flanges may be used at a pressure not exceeding 25 kgf/cm², while the neck flanges steel can withstand a pressure of 200 kgf/cm².
