Seamless Steel Pipes
Seamless Steel Pipe, Carbon Seamless Steel Pipe - Used for oil and gas transportation, the general structure, mechanical structure.
Seamless steel pipe is a hollow cross-section, no seams around the long bar of steel. Seamless steel ingot made of perforated or solid through the capillary tube, and then hot rolled, cold-rolled or cold process. a large number of used pipes is conveying fluids, such as transport oil, natural gas, gas, water pipes and some solid materials, and so on.
Compared to other steel and solid steel bar, the same torsional strength in bending, lighter, is an economic cross-section steel, widely used in the manufacture of structural parts and mechanical parts, such as drill pipe, automotive drive shafts, bicycle rack and construction using steel scaffolding.
Ring with steel pipe manufacturing parts, can improve material utilization, simplify the manufacturing process, saving material and machining time, such as bearing rings, jack sets, has been widely used to manufacture steel. Steel or a variety of conventional weapons indispensable material, gun barrels to make steel. Steel shapes in different cross-sectional area can be divided into tube and shaped tubes. As in the perimeter of equal conditions, the largest area of a circle with a circular tube can carry more fluid. In addition, the circular cross section to withstand internal or external radial pressure, the force is uniform, so the vast majority of the pipe is pipe. However, the tube also has some limitations, such as under the conditions by plane bending, tube as good as square, rectangular tube large flexural strength, the skeleton of some farm machinery, steel and wood furniture on the popular square, rectangular tube.
