  • Secure joint: handles high-pressure fluids and gases reliably
  • Compact design: low profile compared to other flange types
  • Counter bore option: pipe inserts deeper into the flange
  • Easier alignment: the larger welding area speeds up fit-up
  • Lower cost: saves time and labour during welding
  • Fewer failures: reliable forged flanges reduce failure risk and related costs

Manufacturing process of ASTM A815 WP-W flat socket weld flanges

The manufacturers cut the raw material into appropriate sizes and shapes based on the flange dimensions. Then, the manufacturer heats the cut blanks to improve the workability of the ASTM A815 WP-W flat socket weld flange.

After forging, the formed flanges undergo machining operations to achieve the required dimensions, tolerances, and surface finish. The socket weld portion of the SA 815 UNS S31803 socket weld pipe flanges is prepared by machining a bevelled edge.

Cost Benefits of A815 S31803 Counter Bore Socket Weld Flanges Over Alternatives

A815 S31803 counter bore socket weld flange has a counter bore feature that allows the pipe to be inserted deeper into the flange. The larger welding area facilitates easier alignment during the welding process which can save time and labor expenses. The reliability and durability of the A815 UNS S31803 socket weld forged flange reduce the likelihood of failures and associated costs.

Coating Types Used on ASTM A815 UNS S31803 SWRF Blind Flanges

Fusion-bonded epoxy coating is a thermosetting polymer coating applied to the ASTM A815 UNS S31803 swrf blind flange. Zinc coatings such as hot-dip galvanizing or zinc electroplating provide corrosion protection through sacrificial cathodic action to the flange.
