The newly developed Integral forging hollow sucker rod is made of non-seam fine alloy steel pipe. Rod ends are formed by continues upset instead of welding. Two pin-ends are manufactured into double-sealing structure. This rod has special advantages of high strength, bearing high load, keeping the pressure of pouring medium and avoiding leakage etc. When hot water or steam is poured into the hollow sucker rods or when cable is putted into the hollow sucker rods, it is capable of heating crude oil in order to lower the viscosity of crude oil, to prevent the condensation of crude oil and to melt the paraffin in crude oil. It is used for the oil well of high viscous oil, high condensation point oil.
