Description
Baoji QiYueXin Metal Materials CO.,LTD (QYX) 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. Titanium Forging Neck weld butt flange fall under the group of specialty flanges, reinforcement in services at higher temperatures in the oil industry. Titanium Forging Neck weld butt flange is preferable in the petroleum and chemical industry as they operate under actuating temperature ranges.
