The anchor flange combines two butt welding flanges with the appearance of bolt connection, cancels the gasket and makes the integral forged steel flange. It is connected with oil and gas pipelines by welding, and is fixed with anchor piles by flange and flange body, so it can be used for the connection of fixed pipelines, which is suitable for the fixed connection of many process stations and line valve chambers.
Anchor flange is an engineering Bai component. When the pressure Du is small, the short pipe with thrust ring can be used instead, or called through wall casing. For the connection of fixed pipe which needs to be buried in the ground or not to be overhauled for life, and the pressure is large, the conventional flange is used, which can not make the high-pressure pipeline work normally. The utility model relates to an axisymmetric ring body with flange. The two sides of the flange are symmetrical flange necks, and the ports of the two flange necks are welded with the ends of the pipeline respectively, and are embedded in the anchor pile. Because the two flanges connected by bolts in the prior art are combined together and the sealing gasket is cancelled, a kind of integral flange is made, which is connected with the pipeline by welding, and is fixed with the anchor pile by its flange and flange body, so it can be used to fix the connection of pipeline.
