Product Description
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.
The most of flanges are usually made by grey iron. They have good corrosion resistance, wearing resistance, and it is very strong, non-deformation. Moreover, the cost of grey cast iron is cheap.
The ductile iron flange is more expensive than grey iron, but it has better strength and elongation.
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. Flanges help to keep the pipes stay strong without the risks of leakage.
In high pressure zones, welded flanges can prevent the pipes from corrosion, but they will reduce flow rate. In low pressure areas, it is recommended to use flanges with bolts as it facilitates smooth flow.
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. All these coatings could prevent rust effectively.
In general, sand casting process is fitted for the manufacture of flange. The necessary machining will be needed to meet the requirement of flatness. In China, most of iron foundries could produce flange castings.
1) We can do different kinds of surface treatment after casting, such as machining, polishing, and plating
2) We make them by precision casting, investment casting and steel sand casting process in Ningbo, China
3) They are using for Auto machine and others
4) Machine parts (machining parts or machinery parts), matelwork (metal products) and stamping parts.
