Weld Neck Flange
Typically sold to industries that have a process based piping system, weld neck flanges are the most widely used type of flange. Many Weld Neck Flange Manufacturer prefer using the ASME B16.5 standard as a guidance system while producing these flanges. Since the ASME B16.5 standard allots requirements in terms of the material used, pressure and temperature rating, a pre-defined set of tolerances in addition to the testing methods to be used, size and dimensions as well. The pressure ranting for an ASME B16.5 Weld Neck Flange ranges between class 150 to class 2500. Although one of the more expensive costing devices used in a piping system, most industries prefer using the class 150 WNRF flange since they offer the highest level of joint integrity on account of being Butt-welded to a pipe.

Moreover, these pipes are used for both high temperature as well as high pressure applications. Generally, stainless steel grades are preferred for high temperature settings, while carbon and alloy steel grades are used for pressure settings. Since the Carbon Steel Weld Neck Flange is to be butt-welded, the carbon content of the alloy needs to be less, in order to facilitate the welding process. And since carbon steel grades cost low, the cost of producing them is lowered too. In comparison to both alloy steel and carbon steel grades, the Stainless Steel Weld Neck Flange is more expensive. However, the fact that stainless steel flanges outperform either of the forementioned grades, makes up for its expensiveness.
