Hongfu Pipeline Industry Co., Ltd. gives you detailed information about centrifugal ductile iron pipes. Centrifugal ductile iron pipes are divided into continuous ductile iron pipes and centrifugal ductile iron pipes (Ductile Cast Iron Pipes) according to different casting methods.
The main components of ductile iron pipes are carbon, silicon, manganese, sulfur, phosphorus and magnesium. Implementation of standards GB/T13295-2003 ISO2531/2003
The definition of ductile cast iron pipe uses No. 18 cast iron water after adding nodulizing agent, and it is called “Ductile Cast Iron Pipes†(abbreviated as ball pipe) after centrifugal centrifugal casting of spheroidal graphite cast iron machine. Ductile iron pipes and ductile cast pipes.
Centrifugal ductile iron cast pipe cast pipe cast iron. Cast iron pipes are used for water supply, drainage and gas pipelines. They include straight cast iron pipes and fittings.
Compared with gray cast iron pipe, ductile cast iron pipe has advantages of high strength, good toughness, thin wall, small amount of metal, can withstand higher pressure, effective length is 5 meters and 6 meters; according to different wall thickness, P, G Two levels. Is the development direction of cast iron pipe.
The connection between the pipe and the pipe adopts socket type or flange type interface; according to the function, it can be divided into two kinds: flexible interface and rigid interface. The flexible interface is sealed with a rubber ring, allowing a certain degree of rotation and displacement, so it has good shock resistance and tightness. It is simpler and quicker to install than a rigid interface, and it is labor-intensive according to different casting methods.
Aluminium honeycomb panels rely on aviation-grade sheet aluminum for the faces with an aluminum honeycomb in the center. This creates excellent rigidity, but the panels weigh much less. For instance, an aluminum honeycomb panel weighs 1/5th what a solid aluminum panel weighs, and 1/10th of what a solid steel panel weighs.
The honeycomb panel is a revolutionary product that offers superior strength, crack-resistance, ease of installation, and amazing affordability. KM Haus offers two types of honeycomb panels: aluminum and stone. Each utilizes a large format that speeds installation.
Aluminum honeycomb panels are an excellent choice for metallic modern facades on commercial or residential buildings.
