4 Inch ASME B16.11 Black Pipe Tee For Metallurgy

4 Inch BS EN 10253-2 Butt Weld Equal Carbon Steel Pipe Fitting Tee

        Typical materials used in the production of EN 10253 Butt Welding Pipe Fittings Tee include grades such as 16Mo3, 13CrMo4-5, P235GH, P265GH, P355NH, and L450QB, etc. Similar to most European standards, the materials too have varying designations, which indicate if the material is to be heat treated, its application as well as its minimum yield strength in N/mm2. For instance, the designations in en 10253-2 p235gh include the letter P, H & G. The letter P stands for steels intended for pressure applications, the letter H stands for hollow section and lastly, the letter G is a reference to its general characteristics. The minimum yield strength of EN 10253-2 Pipe Fitting Tee produced in grade P235GH is about 235 N/mm2.

　　Butt-welding fittings such as the en 10253-2 type a tee is produced with a reduced pressure factor. The wall thickness at the bevelled ends, as well as the body of the fitting, is the same as a pipe which is produced with the same specified wall thickness. The resistance of a type A fitting to internal pressure is normally less in comparison to that of a pipe, which has been produced with the same specified dimensions. The main difference noted between en 10253-2 type a vs type b is that Type B fittings are intended for use at full pressure applications. Moreover, type B en 10253-2 reducer has an increased wall thickness at its body. Therefore, they are designed to withstand the same pressure, just as a pipe produced in the same specific dimensions.
