Cylindrical Housing Body with Flanged Tubular Housing and Machined Top, Radial Fillets

316L and 304 stainless are the two grades most specified for a flanged tubular housing with machined top and radial fillets; 316L is required for pump & valve, wind energy, and semiconductor process flanged tubular housing applications where chloride pitting or chemical media resistance is a service requirement, while 304 provides adequate corrosion protection for dry robotics, drone, and machinery environments at lower material cost. Flange face flatness above Ra 3.2 μm prevents the gasket from achieving uniform compression and creates a leak path at the low side of the joint. Hangzhou Pengbo Precision Machinery (Hangzhou, Zhejiang, established 2009, ISO 9001 certified) turns and bores this cylindrical flanged tubular housing at their north of 20,000 m² Hangzhou facility using boring & milling, milling & turning, and vertical turning, with flange face flatness, bore diameter, and fillet radius cross-checked with your released dimensions at first article sign-off. Pengbo serves pump & valve, boiler, pressure vessel, wind energy, and robotics flanged tubular housing applications, supporting shipbuilding, drones, and fasteners projects. To quote, we need your drawing showing flange face flatness, bore diameter, fillet radius, and stainless grade and request a pricing from our Hangzhou engineers.
