Extension Rod

The Extension Rod For Mud Pump is one of the important parts of the power end. Its function is to transfer the power to the hydraulic end. The extension rod material is 35CrMo. The surface is chrome plated, and smooth after finishing grinding, which greatly improves the wear resistance and corrosion resistance. Our company can produce F series, 3NB series mud pump supporting various specifications of the extension rod. The middle pull rod, also called the intermediate rod, is an important part of connecting the crosshead and the piston rod, is the key part of connecting the mud pump power end and the hydraulic end.One end is connected to the crosshead, and the other end is connected to the piston rod through a clamp.It has a stuffing box assembly on its outer surface.In the reciprocating movement, the outer circle of the middle pull rod and the seal in the packing box rub with each other, in order to ensure the wear resistance, the outer surface of the middle pull rod is plated with hard chromium. Other names are Extension drill steel, Extension drill rod, and Extension steel, M/F rod(Speed rod), produce Hexagonal and round cross-sections, Hexagonal rods are more rigid, heavier and transfer energy more efficiently, while increasing flushing. Round rods are generally lighter than hexagonal rods and are normally used in extension drilling applications. With the longer steel tending to be larger in diameter conventional extension steel is characterized by duplicate thread on each end of the steel. We have complete range of tools Extension rods including male male and male-female configurations, round and hex shapes, different lengths and different heat treatment options.Those products used for drifting and tunneling project ranging from mining to dams and other civil engineering projects.

Male/female (m/f) rod, speed rod M/f drill steel is an alternative to couplings sleeves to include the female part of the threaded connection as an integral part of the drill steel. M/f drill steel provides more rigid connections and is easier to uncouple and handle. The service life also tends to be better than with separate couplings. The advantages of drilling with m/f steel include: easy handling, quicker uncoupling, tighter connections, the potential to drill straighter holes, and longer service life.

Taper drill rod is used for rock drilling, blasting holes and other drilling works in the quarries, coal mines, traffic and other contractions. It works with taper drill bits and has different length for various applications, our taper drill rods come in a variety of taper angles, generally, the light duty rock drill usually use 7 taper or smaller taper angle, the heavy duty rock drill mainly use 11f=12 taper angle. And the basic theory is that taper drill rods and taper drill bits must be in the same tapered degree. We provide tapered rods in a full range of shank configurations and steel hex diameters for hand-held pneumatic drilling needs. 1,1+Steel grade: 55SiMnMo++40SiMnCrNiMo, 95CrMo equivalent to SANDBAR 20 or C253, 2,Shank size: hex.22mmf-108mm , hex.22mmf-159mm, hex.22mmf-80mmhex.25mmf-108mm. hex. 3,Taper:6fp++7fp++11fp++12fp++etc 4,Length:0.5m-9m 5,Package: in wooden case or in bundles. 6,Supply ability:3000MT/month 7,Delivery time :30days 8,Payment terms:T/T or L/C.
