Merchandise Introduction
EPT extension rods are employed during the globe for best-hammer creation drilling in mining, tunnelling, construction and quarry work. Extension rod, EPT names are Extension drill steel, Extension drill rod, and Extension steel, M/F rod ( Speed rod ) , Make Hexagonal and round cross sections, Hexagon rods are more rigid, heavier and transfer power more effectively, whilst increasing flushing. Round rods are typically lighter than hexagonal rods and are generally utilized in extension drilling purposes.
Male / Female (M/F) rod, velocity rod M/F drill steel is an alternative to couplings sleeves to include the feminine component of the threaded relationship as an integral portion of the drill metal. M/F drill steel provides much more rigid connections and is less complicated to uncouple and deal with. The support existence also tends to be greater than with independent couplings.
Prime hammer drilling principle
one. When the piston hits the shank, kinetic power in the piston generates a compressive wave in the string of drilling tools, that will trigger the bit to penetrate the rock
2. Piston velocity at impact 10m/s but the compressive wave in the drill steel trave EPT at a velocity of 5180 m/s (velocity of seem in metal)
3. The little bit is compelled ahead and penetrates the rock around 1. mm
4. Portion of the vitality not utilised to penetrate the rock goes back again as a tensile wave and element of it as a compressive wave

Product benefit
one.Content are developed by cooperated with Nationwide & Regional Joint EPT Laboratory for Large-functionality Metal Composition Materia EPT and Sophisticated EPT Technology to improve the tiredness resistance of drilling steel.
2.Content is from Baosteel with stringent method of metal smelting and rolling: Refining – Vacuum – Steady casting – drilling gap method – surface area peeling to management the content of non metallic inclusion and harmful element.
three.Strictly manage precision thread method to steer clear of thread too sizzling and damaged effected by the large vibration and shaking of thread component when it functions.
4.Warmth remedy: Fully Carburization – Air great quenching – tempering. It make the rod hold large toughness and enhance floor harness and complete energy as nicely.
5.Thread improve: enhance the thread components to enhance the dress in-resistance and longevity of the rod.
