The application of flanges Flanges are commonly used in plumbing systems, water systems, electrical factory, pipe connection and building construction etc. It is convenient for maintenance and its life time is long.Business Flange is also called as flange plate, which is normally used for connecting two pipes together through the bolts or the welding method.
The type of flanges includes welding neck flange, slip on flange, socket weld flange, lap joint flange, threaded flange and Threaded Rod Bsw blind flange The materials of flanges The materials of flanges include grey iron, ductile iron, cast steel, carbon steel, and stainless steel, of which grey iron and ductile iron are the most common materials. For the whole article, please check Dandong Foundry Blog. The flanges are available in various shapes and the most common ones include rectangular, oval and round. The most of flanges are usually made by grey iron. In low pressure areas, it is recommended to use flanges with bolts as it facilitates smooth flow.
html Related Articles - flange castings, made in China,. In China, most of iron foundries could produce flange castings. The surface treatment of flanges The surface of flange should be used rust resistant coating, such as electro galvanizing, bituminous paint, powder coating and so on. In general, sand casting process is fitted for the manufacture of flange. The ductile iron flange is more expensive than grey iron, but it has better strength and elongation. This article was from Dandong Foundry. In high pressure zones, welded flanges can prevent the pipes from corrosion, but they will reduce flow rate. Flanges help to keep the pipes stay strong without the risks of leakage. All these coatings could prevent rust effectively. iron-foundry iron-foundry flange-casting. Moreover, the cost of grey cast iron is cheap. They have good corrosion resistance, wearing resistance, and it is very strong, non-deformation. The necessary machining will be needed to meet the requirement of flatness
