Q:How seamless steel tube is formed?
Seamless steel tubes are formed by cold drawing and hot rolling.
Q:What's the use of steel pipe?
(processing workshop of Tianjin steel pipe company as a result of the steel pipe truss structure, the actual steel saving up to 42.9%), with a steel pipe manufacturing highway bridge can not only save steel, simplify the construction, but also can greatly reduce the coated area, saving investment and maintenance costs.
Q:Can stainless steel pipes spray black paint?
Stainless steel pipes can spray black paint.The stainless steel surface with a layer of smooth surface, so the painting before the need to use corner grinder or iron brush to paint out into hair and then paint. Otherwise, spray paint can not be adhered to the surface of the stainless steel pipe.
Q:What does "buried steel pipe" 6*2SC100 mean?
The embedded steel pipe 6*2SC100 refers to a welded steel pipe with 2 pipe thicknesses of 6mm and a diameter of 100mm. SC pipe means welded steel pipe. Embedment means pre installation (burial).
Q:Galvanized steel pipe in addition to good rust resistance, what are the advantages?
First, the surface of the steel pipe is treated by embroidery, which is more durable, not faster than the rapid oxidation, and will not form white rust on the steel tube;Two. The steel pipe is fully protected. After heating, each part of the steel pipe is plated with zinc, and the concave convex part is protected;
Q:Which is cheaper, angle iron or steel pipe?
The model does not mean the size of the different edges and sizes of the same model. Therefore, the width, the edge and the thickness of the angle iron should be filled out in the contract and other documents, so as not to be indicated by the model alone. Standard Specification for hot-rolled equal angle iron is 2#-20#. The angle iron can be made up of different force components according to the different structure, and can also be used as the connecting piece between the components. Widely used in a variety of architectural and engineering structures, such as beams, bridges, towers, hoisting and conveying machinery, ships, industrial furnace, reaction tower, container frame and warehouse.
Q:What does "SC50" steel pipe mean in civil engineering?
The corrosion resistance of Ni is very strong in acidic environment. In the environment containing sulfuric acid or hydrochloric acid, the higher the content of Ni in the welded pipe is, the stronger corrosion resistance is. In general circumstances, the addition of Cr in a T-junction steel pipe prevents erosion. The marginal condition of the steel strip is another important cause of the wrong edges. The influence of mass flow rate, heat flux density and structural parameters (ratio of spiral curvature diameter and diameter of T-shape welded tube Dc/D) on heat transfer coefficient of saturated bubble boiling in vertical helical tubes.
Q:The outer circle of a seamless steel pipe 50 head into the outer circle of the 40 to close
That is, according to the production process of different classification, different from hot rolling (expansion) pipe. In the process of expanding the tube or raw material tube, it is processed by multiple cold drawing, usually on single chain or double chain cold drawn machine of 0.5 ~ 100T. Cold rolled steel pipe (DIAL) in general, steel pipe for low and medium pressure boiler tube, high-pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, oil cracking tube, machining pipe, thick wall pipe, small diameter and cold drawn steel tube also includes other tubes, carbon thin-walled steel, alloy thin-walled steel pipe, stainless steel pipe, special-shaped wall steel pipe. The outside diameter of cold drawn steel tube wall thickness to 6mm, to 0.25mm, to 5mm diameter thin-walled tube wall thickness is less than 0.25mm in size, accuracy and surface quality were significantly better than the hot (expanding) tube, but by the process control, its diameter and length are limited.
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:What is the outer diameter and wall thickness of the welded steel pipe of national standard DN250?
DN (nominal diameter) 250 is generally the industry said 273, welded steel pipe (spiral steel pipe) thickness is generally between 6-8mm, more common.
