Second, the seamless steel pipe
Is a
hollow section, no seams around the long bar of steel? Steel hollow section, a
large number of pipes used for transporting fluids, such as transportation of
oil, gas, gas, water and some solid materials, pipes 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. The ring with a
steel pipe manufacturing parts, can improve material utilization, simplify the
manufacturing process, saving materials and processing time, such as bearing
rings, jack sets, has been widely used to manufacture steel. Steel or a variety
of conventional weapons indispensable material, barrel, barrel, etc. to make
steel. Steel shapes in different cross-sectional area can be divided into tube
and shaped tubes. Because 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 pipe is pipe. (021-57590228)
However,
the pipe also has some limitations, such as under the conditions by plane
bending, tube as good as square, rectangular tube bending strength of a large
number of farm machinery skeleton, steel and wood furniture on the common
square and rectangular tube. Depending on the application needs to have shaped
pipe other cross-sectional shapes.

Third,
welded steel pipe
Welded
steel pipe, also known as, is a steel plate or strip after curl forming welded
steel. Welded steel pipe production process is simple, high production
efficiency, different specifications, less capital equipment, but the general
strength of less than seamless steel tubes. Since the 1930s, with the progress
of high-quality steel rolling production and the rapid development of welding
and inspection techniques, and continuously improve the quality of welds,
welded steel pipe increasing varieties and specifications, and in more and more
areas instead of nothing pipe joints. Welded steel pipe welds in the form of
divided Longitudinal and spiral welded pipe.
Longitudinal
production process is simple, high efficiency, low cost, rapid development.
Spiral Welded Longitudinal generally higher than high, can narrow the billet production
of large diameter pipe, you can also use the same width of the billet
production of different pipe diameters. However, compared with the same length
of straight pipe seam weld length of 30 to 100%, and lower production rate.
Therefore,
smaller diameter pipe was powered by straight seam welded, large diameter
spiral welded pipe for the most.
