What are the ingredients of ductile iron manhole covers? Let's introduce the composition and application of ductile iron manhole covers:Cast iron is an iron-carbon alloy with a carbon content of more than 2%. The carbon content of industrial pig iron is generally 2.5%-4%, and contains C, SI, Mn,
With the rapid development and progress of modern elbow forming technology, pipelines have played an increasingly important role in all walks of life, especially in power engineering, crude oil and other industries. The further improvement of the regulations on machinery and equipment encourages the
Carbon steel tees are generally used for the installation of regulating valves, and the use of exhaust. Concentric reducers are conducive to fluid flow, and have less interference with fluid flow when changing diametersThe seamless tee therefore uses concentric reducers for gas and vertically flowin
Carbon steel elbow is a kind of pipe fitting used in the turning of pipelines. Commonly used are 90-degree elbow, 45-degree elbow and 180-degree elbow. Carbon steel elbows are relatively cheaper than stainless steel elbows, so they are used in a large proportion in fluid pipeline construction. Gener
