Flange factory


 what's machine you do for these machining parts?
A: we have high precision machining center to produce for small tolerance products and we also have some automatic CNC machine, CNC machine, stamping machine, automatic drill-hole machine and sandblasting maching etc, except the plating, we do whole producing process in own factory.

Product Details

ASME/ASTM Flanges
Pipe flanges that are made to standards called out by ASME B16.5 or ASME B16.47, and MSS SP-44.
They are typically made from forged materials and have machined surfaces. ASME B16.5 refers to nominal pipe sizes (NPS) from ½” to 24″. B16.47 covers NPSs from 26″ to 60″. Each specification further delineates flanges into pressure classes: 150, 300, 400, 600, 900, 1500 and 2500 for B16.5, and B16.47 delineates its flanges into pressure classes 75, 150, 300, 400, 600, 900
