NXF ASTM A240 316H /1Cr17Ni12Mo2/31609 DN15-1200 Class 150-2500 Threaded Tee

The threaded tee is a type of industrial pipe fitting. Its main function is to divert the passing medium. The production process of threaded tees is divided into two types: forging and casting. Forging refers to heating and forging a steel ingot or round bar, and then processing the thread on a lathe. Casting refers to melting the steel ingot and pouring it into the mold of the tee, and then waiting for it to cool. Because of the different manufacturing processes, the pressure they can withstand is also different. The pressure resistance of forging is much higher than that of casting. The main manufacturing standards for threaded tees generally include GB/T14626, ASME B16.11, and BS3799.
