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:Heating system DN40 and DN32 welded steel pipe how to connect?
As for the flange connection: low pressure pipeline is generally not used in this way, can be divided into threaded flanges and flange welding flange, and the flange connecting pipes of different diameters, only the welded flange to diameter, said in a low pressure pipeline which has low pressure pipe connection make an unnecessary move, this is not much, but there are also people with non the standard flange for connecting different pipe diameter, which is not consistent with the technical specification!
Q:Which is better, galvanized steel pipe or stainless steel?
Most of the use requirements are to maintain the original appearance of the building for a long time. In determining the type of stainless steel to be chosen, the main consideration is the aesthetic standards required, the corrosivity of the atmosphere in the area, and the cleaning system to be adopted. However, other applications increasingly seek only structural integrity or watertightness. For example, the roof and side walls of industrial buildings. In these applications, the construction cost of the owner may be more important than the aesthetic, the surface is not very clean can also. The use of 304 stainless steel in a dry indoor environment is quite effective.
Q:What are the advantages of PVC pipe and galvanized steel pipe?
Galvanized steel pipe is also used, because some areas require the use of strength. Moreover, the iron and steel industry is a pillar industry, there are some unspoken rules in it.
Q:What are the uses of welded steel pipes?
Low pressure fluid conveying galvanized steel tube (GB/T3091-1993) is also called galvanized pipe, commonly known as white tube. It is used for hot water, gas, air, oil, heating, steam, warm water and other generally low pressure fluid or other hot dip galvanizing (furnace welding or welding) steel pipe. The wall thickness of the steel pipe is divided into ordinary galvanized steel pipe and thick galvanized steel pipe. The end of the pipe is divided into non - threaded galvanized steel pipe and threaded galvanized steel pipe. The specification of steel pipe is expressed by nominal caliber (mm). The nominal diameter is the approximate value of the inner diameter. Usually used in inches, such as 11/2.
Q:How can seamless steel tubes be produced?
After extrusion to remove pipe sizing. The sizing machine passes through the cone bit and rotates into the steel embryo at high speed to form a steel tube. The inner diameter of the steel pipe is determined by the outside diameter and length of the sizing machine. When the steel tube is fixed, it enters the cooling tower and is cooled by spraying water. The steel tube is straightened after cooling. After straightening, the steel pipe is sent to the metal flaw detector (or water pressure experiment) by the conveyor belt for internal inspection. If there are cracks in the steel pipe, bubbles and other problems will be detected. Steel pipe quality inspection, but also through strict manual selection. After the quality inspection of the steel pipe, spray with the paint on the number, specifications, production batch number and so on. The crane is hoisted into the warehouse.
Q:What connections are there for concrete filled steel tubular column foundations?
In the connection work, strengthening ring joint stiffness, high bearing capacity and no parts through the tube, it is especially suitable for the small diameter steel tube concrete column structure, complex engineering projects, especially those in the pump sending pouring construction method, which is more important, it has a basic guarantee strictly for the quality of concrete construction. When concrete columns with larger diameter, ring type joint construction steel is large strengthened, so as to make the project construction become more complex, and the connection between the longitudinal rebars becomes cumbersome.
Q:A333gr6 steel pipe and domestic material of the same?
A333Gr.6 steel is no nickel steel is a kind of fine grain aluminum low temperature toughness of steel, therefore, also called Al killed steel. A333Gr.6 belongs to the United States ANSI and ASTM-SA333 cryogenic steel standards and is used at the lowest impact temperature of -46 degrees celsius. Its temperature, range of use and fracture toughness value are similar to those of domestic 16Mn steel (the minimum usage temperature of 16Mn steel is -40 degrees Celsius).
Q:Seamless steel tube DN15 specification phi 18*3 what do you mean?
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 with solid steel such as round steel, steel tube is lighter in strength and equal in resistance to bending and torsion. It is an economical cross section steel and is widely used in the manufacture of structural and mechanical parts.
Q:Where is a steel pipe casing usually used?
A straight tube of carbon steel sheathed on pipes and tubes and threading tubes to protect the joints from damage by electric welding. The purpose is to protect the wires and cables.
