Q:Hot galvanized steel pipe for use?
The use of hot galvanized steel pipe: mainly used for the delivery of gas, heating.In the greenhouse gas, heating, with the kind of pipe and galvanized pipe, galvanized pipe as a water pipe, produced a lot of rust in the tube, the outflow of water not only pollute the sanitary ware, and mixed with smooth inner wall corrosion caused by bacteria, heavy metal content in the water is too high, serious harm to human health. 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 have also issued a civilization, from two, 000 years since the prohibition of galvanized pipe, the current New District cold water pipe has rarely used galvanized pipe, and some of the hot water pipe is galvanized pipe.
Q:What is the theoretical weight per square meter of the steel pipe diameter of the outer frame and the thickness of the tube wall 3mm 48mm?
Formula: outside diameter - wall thickness * wall thickness *0.02466=, weight per meter! : 48-3*3*0.02466=3.3291
Q:How can galvanized steel tubes be painted on the surface?
The market is commonly used in alkyd iron red primer, iron red epoxy primer are not suitable for galvanized parts, otherwise it is easy to fall off. It is important to point out that the saponification of the galvanized sheet with alcohol, acid and paint will result in the failure of the coating and the damage of the original zinc coating.
Q:What is the weight of hot galvanized steel tubes? DN150 4mm wall thickness
DN150 4mm wall thickness welded steel pipe theoretical weight is 16.21kg/m, galvanized steel pipe should be multiplied by the weight coefficient after galvanizing, C, DN150, wall thickness of 4mm, C=1.032, DN150, theoretical weight and wall thickness of 4mm galvanized steel is 1.02*16.21=16.7287kg/m = 16.73kg/m.
Q:The outer circle of a seamless steel pipe 50 head into the outer circle of the 40 to close
Cold drawn steel tube and cold rolled steel pipe mill is a complete set of equipment which combines cold rolling, cold drawing, cold rolling and cold drawing to produce pipes. It is a unit for deep processing of hot-rolled pipes or welded pipes.
Q:Which is more load-bearing, the same thickness of steel pipe and steel bar?
The magnitude of the axial force acting on the steel member is only related to three factors, namely, the strength of the material, the sectional area of A and the longitudinal stability factor of F.
Q:What does carbon seamless steel pipe mean? What is the difference between a seamless 20# and an ordinary one? What is it used in detail?
Carbon steel is actually relative to alloy steel, mainly carbon content, and 20# seamless steel is carbon steel! In addition, there are stainless steel, stainless steel is considered a kind of alloy steel, but the processing is not the same, the performance is not the same, good looking outside!The description of the material in alloy steel is actually the content of the metal elements in the steel (usually the percentage number).
Q:Why should the weak electricity be pre buried with galvanized steel pipe?
Galvanized steel is widely used in construction, machinery, coal, chemical industry, railway vehicles, automobile industry, highway, bridge, container, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery and other manufacturing industries.
Q:What does seamless steel tube mean? What are the main uses? What are the classifications?
Seamless steel pipe having a hollow cross section, used as a conduit for conveying fluids, such as pipelines for transporting petroleum, natural gas, gas, water, and certain solid materials. Compared withsteel and roundsteelinsolid, flexural torsional strength in the same time, the weight is light, is a kind of economic section steel, widely used in the manufacture of structural parts and mechanical parts, such as the oil pipe, automobile transmission shaft, the bicycle frame and steel construction with scaffold with steel pipe manufacturing ring parts can be improved the utilization rate of materials, simplify the manufacturing process, material saving and working hours, has been widely used to manufacture steel tube.
Q:Is the seamless steel pipe used in the market hot or cold drawn?
Outside diameter 89, most are cold drawn, more than 89 hot rolling.
