  常用法兰包括平焊法兰、对焊法兰、承插焊法兰、螺纹法兰。 最新的一种法兰叫锚固法兰， 锚固法兰是一种工程构件。在压力较小的地方可以用带止推环的短管代替，或者称作穿墙套管，对于要求埋入地下或终生不检修的固定管道的联接，且要求压力较大时，采用常规法兰，不能确保高压管道安全可靠的工作。实用新型是一种带有凸缘的轴对称圆环体，其凸缘的两侧为对称的法兰颈部，两个法兰颈部的端口分别与管道的端口焊接，埋入锚固桩中。由于将现有技术用螺栓连接的两个法兰合并在一起，取消密封垫，制成一种整体的法兰，通过焊接方式与管道联接，并靠其凸缘和法兰体与锚固桩固定，从而可用于固定管道的联接。更适用于我国“西气东输工程”管道系统中，许多工艺站场、线路阀室的固定联接。

“Anchor Flange”是由中国过滤器网提供的国际阀门新闻，译文仅供参考。另外，中国过滤器网还提供相关产品搜索： SY4P法兰连接Y型过滤器、 SRB系列篮式过滤器、 SB14/ST34法兰连接T型过滤器 F43X双封自净式防逆水封阀、 HS41X防污隔断阀(管道倒流防止器)等。

译文：
Anchor Flange Common flanges include flat welding flange, butt welding flange, socket welding flange, threaded flange. The latest of a flange is called anchoring flange, anchor flange is an engineering component. Where the pressure can be used with smaller thrust ring instead of a short tube, or called wall bushing, buried underground or life for the required maintenance of the fixed pipeline is not connected, and the required pressure, the conventional method blue, can not ensure safe and reliable high-pressure pipe work. Utility model is an axisymmetric ring with a flange body, the flange is symmetrical on both sides of the neck flange, two neck flange ports were port and pipeline welding, anchor buried in the pile . As the use of existing technology to connect the two flange bolts combined, canceled gaskets, flange made ​​of a holistic, connected by welding and pipe, and by its flange and fixed flange body and the anchor piles, which can be used for fixed pipe connection. More suitable for China's "West-East Gas Project" pipeline system, many craft station, valve chamber of the fixed line connection.
