Flange, also called flange flange flange disk, or flange. The flange is a part of the interconnection between shaft and shaft, used for the connection between the pipe ends; also used in the flange on the import and export of equipment, used for the connection between two devices, such as reducer flange. The flange connection or flange joint is a detachable connection consisting of a flange, gasket and bolt interconnected as a set of the combined sealing structures. The pipe flange refers to the flange used for piping in piping installations, and the flange used for equipment refers to the import and export flange of the equipment. There are holes on the flange, and the bolts make the two flanges tightly connected. The flange is sealed with a gasket. The flange is divided into threaded connection (fillet connection) flange, welding flange and clamp flange. Flanges are used in pairs, low-pressure pipelines can use a wire connection flange, four kilograms of pressure above the use of wel...

The key difference between galvanized and hot-dip galvanized is that most galvanized materials have smooth and sharp finishing, whereas hot sip galvanized structures have a rough finishing.   Galvanization is a process of preventing metal surfaces from corrosion. After the completion of galvanization, we say that the surface is “galvanized” if it is done via the usual procedure. However, if we use the hot dipped method, we call it a “hot-dip galvanized surface”.   What is Galvanized? A galvanized surface is a metal surface that has a zinc layer for protection from corrosion. We call the process of applying this zinc layer “galvanization”. Moreover, this application is done on steel or iron surfaces. There are different types of galvanization, including:   Hot dip galvanization – immersion of the item in molten zinc Continuous galvanizing – a form of hot dip galvanization, but this method forms a thinner zinc layer; thus, the corrosion resistance is comparatively less Ther...
