Q:What is the disadvantage of nodular cast iron in excess of silicon?
Silicon has a great influence on the performance of nodular cast iron. It mainly shows that silicon can refine graphite and improve the roundness of graphite ball.
Q:It's not easy to drill ductile iron with cobalt high speed steel bit. Please help to point it out
The material can be annealed and the process is simple, that is, heating the workpiece and cooling it naturally. In this way, the hardness of the workpiece can be reduced.
Q:Can the underground cast iron pipes be connected with clamps to form buttress?
The hoop has the advantages of beautiful appearance, convenient operation, strong clamping force, good sealing performance, etc.. Mainly used for connecting and fastening vehicle, ship, diesel engine, gasoline engine, machine tools, fire, and other machinery and equipment, chemical equipment general nylon hose, plastic hose, hose cloth, water interface and seal etc..
Q:The difference between ductile iron pipe and steel pipe used in pipe jacking
Comparison between ductile iron pipe and universal cast iron pipe: the process of making ductile iron pipe is cast by adding alkaline earth metal or rare metal such as magnesium and calcium in the raw material of common cast iron pipe.
Q:What is cast iron pipe?
Cast iron pipes (Cast, Iron, Pipe), cast cast pipe. Cast iron pipes are used for water supply, drainage and gas transmission lines. They include cast iron pipes and pipe fittings. Labor intensity is small. According to the casting method, it is divided into continuous cast iron pipe and centrifugal cast iron pipe, in which the centrifugal cast iron pipe is divided into sand mould and metal type two kinds.
Q:Some questions about the bearing capacity of nodular cast iron pipes!
But the key is that the cast iron pipe needs centrifugal casting, especially the longer tube. Therefore, we must understand whether the production plant has this production condition, otherwise, the higher quotation may not be able to produce.
Q:The difference between ductile cast iron pipe and machine-made cast iron pipe
Of different uses, ductile iron pipes are widely used for municipal water supply and drainage, rural drinking water and outdoor fire fighting works; mechanism cast iron pipes are mainly used in the city.
Q:Can ductile iron pipes be installed outdoors?
Ductile iron pipes can be installed outdoors.
Q:Ductile cast iron can replace copper sleeve
The tensile and compressive capacity of the ball milled cast iron is not as good as that of copper. The hardness of Rongchang graphite copper sheath can reach HB210
Q:If the ductile iron pipe is broken, can we use rush repair?
These specifications are also based on the outer diameter of the tube. In daily life, we may also encounter a pipeline rupture, or when it is on the road to repair, excavator accidentally hit PE, PPR water supply and drainage pipeline, as long as a little, can be used to repair the pipeline repair section.
