High Quality Flange DN10-DN2000

High Quality Flange DN10-DN2000

Our flanges are produced through a strict 6-step manufacturing process:

Material Selection - Premium steel billets (carbon steel/stainless steel/alloy) are chemically analyzed

Hot Forging - Heated to 1200°C and precision forged for optimal grain structure

Heat Treatment - Normalizing & tempering to enhance mechanical properties

CNC Machining - Computer-controlled lathes achieve ±0.01mm precision

Surface Treatment - Shot blasting, galvanizing or anti-rust coating

Quality Inspection - 100% dimensional check + UT/RT testing

All processes comply with ASME B16.5 and ISO 9001 standards, ensuring perfect sealing surfaces and long service life.
