Problems solved by technology

[0003] However, the following problems exist in the current petrochemical tank connection flange grinding and positioning. First, most of the flange fixing devices on the market currently fix the surface of the flange, so that the flange can only be fixed on the outer wall. When the flange is polished, it is easy to shake the flange, thereby reducing the quality of the flange, and the outer surface of the flange is clamped and fixed, which is easy to damage the outer surface of the flange; Therefore, there is no set of clamping devices that can stably fix the inner and outer walls of flanges of different specifications. Using multiple sets of clamping devices is not only time-consuming and labor-intensive, but also costly, and can better clamp flanges , improve the grinding quality of the flange

Abstract

The invention relates to a petrochemical tank connecting flange machining treatment system. The petrochemical tank connecting flange machining treatment system comprises a positioning device, an external clamping device and an internal clamping device, wherein the external clamping device is installed at the lower end of the positioning device, and the internal clamping device is installed on thepositioning device. According to the petrochemical tank connecting flange machining treatment system, the following problems existing in the grinding and positioning process of a petrochemical tank connecting flange can be solved, firstly, most of flange fixing devices on the current market are used for fixing the surface of the flange, so that only the outer wall of the flange is fixed, when theflange plate is manually polished, the flange plate is prone to shaking, so that the polishing quality of the flange is reduced, and due to the fact that the outer surface of the flange is clamped andfixed, the outer surface of the flange is prone to being damaged; and secondly, due to the fact that the shape of the flange is irregular, no clamping device can be used for stably fixing the inner wall and the outer wall of the flanges with different specifications, the flange can be better clamped, and the polishing quality of the flange is improved.

Description

technical field [0001] The invention relates to the technical field of flange processing, in particular to a petrochemical tank connection flange processing system. Background technique [0002] Flange, also known as flange flange or flange, is a part that is connected between pipes and pipes. It is used for the connection between pipe ends. Flange connection or flange joint refers to flanges, Gaskets and bolts are connected to each other as a detachable connection of a combined sealing structure. Pipeline flange refers to the flange used for piping in the pipeline device, and used on equipment refers to the inlet and outlet flanges of the equipment. According to the connection method The types of flange connection can be divided into: plate flat welding flange, neck flat welding flange, neck butt welding flange, socket welding flange, threaded flange, flange cover, neck butt welding ring loose sleeve flange , flat welding ring loose flange, ring groove surface flange and f...
