Small caliber thick wall seamless steel pipe, is a hollow section, no joints around the long steel.It is made of steel ingot or solid pipe billet through perforation and then made by hot rolling, cold rolling or cold drawing.Small caliber thick wall seamless steel pipe have hollow section, used for conveying a large number of fluid pipelines, such as pipelines conveying oil, natural gas, gas, water and some solid materials.Seamless steel pipes have hollow sections and are widely used for conveying fluids such as oil, natural gas, gas, water and some solid materials.Compared to the steel pipe and round steel solid steel bending torsional strength phase at the same time, the weight is lighter, is a kind of economic cross section steel, widely used in the manufacture of structural and mechanical parts, such as petroleum drill pipe, auto transmission shaft, bicycle frame and construction of steel scaffolding is used with steel pipe manufacturing annular parts, such as can improve material utilization, simplifying the manufacturing process, material saving and processing time, such as rolling bearing ring, jack sets, etc., has been widely used to make steel pipe.Small mouth, thick wall seamless steel pipe or a variety of conventional weapons indispensable material, gun barrel, barrel, etc. To manufacture steel pipe.According to the shape of cross-sectional area, seamless steel pipe with small mouth and thick wall can be divided into round pipe and special-shaped pipe.Since a circle has the largest area with the same circumference, more fluid can be transported in a circular pipe.In addition, when the annular section bears internal or external radial pressure, the force is more uniform, so most steel pipes are round pipes.
