Long Weld Neck Flanges

HGFF Group Co., Ltd. (HGFF) is an ISO enterprise. Incorporated in 1991, we have expanded ourselves as well our services, products and production patterns, emerging as a manufacturer, supplier and exporter of Long
Weld Neck Flanges in hard-to-nd metals. Long Weld Neck Flanges have a hub that extends from the Flanges at the surface, which helps in accommodating the pipe more easily. Alloy Steel Long Weld Neck Flange fall under the group of specialty flanges, reinforcement in services at higher temperatures in the oil industry. A Carbon Steel Long Welding Neck Flanges
is preferable in the petroleum and chemical industry as they operate
under actuating temperature ranges.
