We specialize in heavy wall seamless steel pipes. The pipes are produced by punching and hot rolling process with the quality steel billet. Blast furnace tap hole drill rod is suitable for various blast furnace tap hole machines. In the production of iron making blast furnace, Blast furnace tap hole drill rod is suitable for various refractory openings, gun mud openings, etc. The scope of application is wider, and it can also complete the chiseling of various non-metallic materials (rocks, refractory materials,gun mud, etc.). The blast furnace tap hole drill rod is made of alloy steel pipe, which greatly improves the fatigue resistance and shear strength. Its main function is to transmit torque and transport drilling fluid, and the borehole is continuously deepened by the gradual lengthening of the blast furnace drill pipe.
The seamless steel pipe has a hollow cross-section and is widely used as a pipeline for conveying fluids, such as pipelines for conveying oil, natural gas, gas, water and some solid materials. Compared with solid steel such as round steel, steel pipe has the same bending and torsion strength and lighter weight. It is a kind of economic cross-section steel, widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipe, automobile transmission shaft, bicycle frame and steel scaffolding used in construction and other steel pipe manufacturing ring parts, which can improve the utilization rate of materials, simplify the manufacturing process, save materials and processing hours. It has been widely manufactured with steel pipes.
