Q:It's not easy to drill ductile iron with cobalt high speed steel bit. Please help to point it out
Choose carbide or whole carbide drill, about 90HRC in hardness. But it requires a high number of drills, around 3000.
Q:Is there a kind of pipe called lined ductile iron pipe? Seeking manufacturers?
The 10kg pressure ball tube is also used as a drain, and the second is the W ductile iron pipe, i.e., without spigot, ductile tube, or lined ductile iron tube.
Q:What is the K9 standard pressure for ductile iron pipes?
Ductile iron pipe is a kind of cast iron. It is an alloy of iron, carbon and silicon. Graphite is exist in spherical form, usually graphite size is 6-7, casting spheroidization grade control requirements for 1-3 quality (spheroidization rate greater than 80%), so the mechanical properties of the material itself has been improved, has the essence of iron, steel performance.
Q:Ductile iron pipe joint damage, water leakage, want to see the connection with other pipe fittings, how to operate?!
Sawing grinding head, increasing steel socket set
Q:What is the acceptance of cast iron pipe material?
A cast pipe made of cast iron. 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.
Q:Ductile iron pipe, socket connection, pipe length, you can cut open it?
The cutting length is 4 meters from the jack. Among them, DN300 below 100% can be cut, DN350 above shear ratio is 10%, cut the small head to do chamfering treatment.
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:What is a slide in type T flexible interface?
As long as the socket is inserted into the slot, the installation is quick, labor-saving and airtight, and what is good is also good
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.
Q:What is the difference between a PE fire hose and a ductile iron pipe?
Galvanized steel pipe: divided into cold galvanized steel pipe, hot galvanized steel pipe, cold galvanized steel pipe has been banned, and the latter is also advocated by the state for the time being. In 60s and 70s, developed countries began to develop new types of pipes, and galvanized pipes were banned. China's Ministry of construction and other four ministries also issued a civilization, indeed from two, 000 years since the galvanized pipe as a water supply pipe, the New District cold water pipe has rarely used galvanized pipe, and some of the hot water pipe is galvanized pipe. Hot dip galvanized steel pipe is widely used in fire, power and highway.
