Non-standard flanges should be produced and inspected according to certain quality requirements.

The production of non-standard flange steel plate should have ultrasonic flaw detection, no layered defects, to ensure its good quality and performance problems, in the production must be in accordance with certain quality requirements to production and inspection, so as to ensure the production and use without any quality problems. However, some pipe connections are welded without flanges.

What are the advantages of rubber flexible joint connection matching flange? Chemical flat welding flange manufacturers sell

The flange rubber flexible joint can effectively compensate and relieve the thrust of the blind plate in the pipeline, and can facilitate the installation, maintenance and replacement of the water pump and the valve. The flange rubber joint is composed of metal casting or welding, and uses the principle of rubber compression elastic deformation. Rubber flexible joint flanges are often used to install various pipelines, especially large and long-distance metal pipelines. Flanges are used for long-term use of pipelines. The so-called stainless steel flanges use flanges as two sections at the pipeline connection. The interface of the pipe is not directly connected to the pipe. The advantage is that compared with the straight pipe butt joint, the stainless steel flange is reliable and the interface is firmer.

Vacuum Flange Type-Field Flange Machining

Compared with GB/T 6071.1~6071.3-1985, Ultra-high Vacuum Flange (GB/T 6071-2003) has the following main changes: (on-site flange repair) adjust the negative tolerance of D1 to positive tolerance; The basic dimensions of some flanges were adjusted, and the outer diameter D36 was changed to D34, D56 to D54, D62 to D60, D71 to D70, D89 to D86. DN(25) and DN250 specifications are added. The knife edge is inclined inward by 5 degrees, and the total depth of the knife edge is adjusted from 1.5mm to 1.2mm; The baking temperature of flange is changed from 450 ℃ to not more than 300 ℃; The nominal diameter DN of flange is directly connected to the bottom surface of flange knife edge. The size of the ring belt of the copper sealing gasket has been adjusted. For convenience, the figure and the corresponding table are arranged together.

Flange bolt fastening method-pressure vessel flange sealing surface repair

Flange connection is to fix two pipes, pipe fittings or equipment on a flange plate, between the two flanges, and add flange pads (on-site flange repair) to fasten together with bolts to complete the connection. Some pipe fittings and equipment have their own flanges, which are also flange connections. Flange connection is an important connection mode in pipeline construction. The flange connection is easy to use and can withstand greater pressure. In industrial pipelines, in the home, the pipe diameter is small, and it is low pressure, and the flange connection is not visible. If in a boiler room or production site, there are flanged pipes and equipment everywhere.
