Many sizes of hollow rods for different usages. Its steel degree is high, and it can withstand strong torque and tension. Mechanical properties are H-grade level. When it is used in deep well, the performance is more reliable with the use of three step assemblage. It can come to the depth of 3,000 meters.
Self-controlled electrical heating sucker rod is a new generation of electric heating rod of the latest products. The product has high heat productivity, and its temperature is self-controlled. Polymer PTC (positive temperature coefficient of resistance) will be installed within the hollow rod as the semiconductor material thermal heating elements. Both ends (male and female) are sealed by fire resistant PTFE material. The temperature of this kind sucker rod can be adjusted according to the complexity of current automatically. Within the entire pitshaft oils temperature is uniform, which saves energy without destroying oil properties. The rod is designed sectional. There is a fuse in every installation of rods, which can protect it in the case of partial flow. Without prejudice to the overall work.
