(Summary description) In the pipeline strength test or sealing test, the Spectacle Blind Flange at the original start-up preparation stage cannot be used at the same time as the connecting equipment. The blind plate should be installed at the junction of the equipment and the pipeline. Various process material pipes are connected in the boundary area outside the boundary area. When the equipment stops running, a Spectacle Blind Flange should be installed at the shut-off valve.

Information

As we all know, pipes are usually connected by some kind of pipe fittings, which we call "flanges". However, in real life, many of us don't know anything about flanges and Spectacle Blind Flanges, and often get confused. Here is a special distinction between flange and Spectacle Blind Flange for you, and the explanation is as follows:

 

T  he Spectacle Blind Flange is a flang  e without a hole in the middle. It is mainly used for the front end of pipe sealing and for sealing ports. Its function is the same as the valve head and pipe cover, but the Spectacle Blind Flange seal is a detachable sealing device, which cannot open the seal of the head aga  in. Spectacle Blind Flange materials include carbon steel, alloy, stainless steel, plastic, etc. Due to its good sealing performance, the Spectacle Blind Flange plays th  e role of isolation, cutting, sealing head, pipe cover, etc. When completely separated, it is usually used as a constant isolation means. The blind plate is a solid plate with a handle. Generally, it is more convenient to use flange blind plates for isolation systems used under general conditions. For normal operation, a yellow throttle ring can also be used to fill the installation gap of the blind plate on the pipe.

 

Flanges (also called flanges or raised edges) are parts that connect pipes, usually with holes at the end of the pipe. When connecting, the flange needs to be fastened with bolts. Flanges are sealed with gaskets, or play a temporary role in the test. Flange is a common valve disc part in pipeline engineering. Generally speaking, according to different connection methods, flanges are divided into threaded connection flanges, welding flanges and clamping flanges. Low-pressure pipelines can be threaded flanges and welded flanges, and the pressure can exceed 4 kg.

 

1. Because of its good performance characteristics, flanges have been widely used in basic projects such as chemical industry, construction, petroleum, sanitation, pipelines, and fire protection.

  

2. In the pipeline strength test or sealing test,   the Spectacle Blind Flange at the o  riginal start-up preparation stage cannot be used at the same time as the connecting equipment. The blind plate should be installed at the junction of the equipment and the pipeline. Various process material pipes are connected in the boundary area outside the boundary area. When the equipment stops running, a Spectacle Blind Flange should be installed at the shut-off valve.

 

Well, the above content is about the difference between flange a  nd Spectacle Blind Flange. I h  ope you have some understanding. After all, only through understanding can we choose suitable connecting pipe fittings to make the pipeline connection closer.
