Weld Neck Flanges

ASME/ANSI B16.5 WELD NECK (WN) PIPE FLANGES MANUFACTURER IN INDIA

MANUFACTURER/EXPORTER OF HIGH QUALITY WELD NECK FORGED FLANGES

CARBON, ALLOY, STAINLESS STEEL WELD NECK FLANGES

Exotic piping Solution INC is a specialised manufacturer of high quality ASME/ANSI/DIN standard weld neck flanges in India. We offer immediate delivery programs for standard size of carbon steel weld neck flanges and stainless steel weld neck flanges.

Weld neck pipe flanges are connected to the pipe by welding the pipe to the neck of the pipe flange, which helps to pass on the stress from the weld neck to the pipe itself. This also reduces high stress concentration at the base of the hub of the weld neck pipe flanges. Weld neck pipe flanges are generally used in high pressure applications, where hot or cold temperatures exist. The inside diameter of a weld neck pipe flange is machined to match the inside diameter of the pipe.

We offer weld neck pipe flanges manufactured at our facility to companies in various industries including shipbuilding, power generation, petrochemical plants, oil refineries, waste water treatment plants, paper mills, pharmaceutical plants and turnkey projects among others.

Our products are widely exported to countries and regions such as the United States, Europe, Russia, Turkey, Malaysia, the UAE, Saudi Arabia, Iran, Brazil, Chile, Mexico, South Africa, Jordan, Tunisia, Vietnam, Indonesia, Thailand, Singapore, Colombia, and Sri Lanka.
