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.
