API Sucker Rod
API Sucker Rod is a steel rod, typically between 25 and 30 feet (7 to 9 meters) in length, and threaded at both ends, used in the oil industry to join together the surface and downhole components of a reciprocating piston pump installed in an oil well. The pumpjack is the visible above-ground drive for the well pump, and is connected to the downhole pump at the bottom of the well by a series of interconnected sucker rods. Sucker rods are also commonly available made of fiberglass in 37 1/2 foot lengths and diameters of 3/4, 7/8, 1, and 1 1/4 inch. These are terminated in metallic threaded ends, female at one end and male at the other.
Hollow sucker rod is a kind of new extraction equipment used to explore the viscosity and high pour crude oilfield. It injects heat carrier(hot oil, hot water, heat),chemical or enter into cable through the central bore of the rod into the wells to achieve the goal of reducing viscosity, thereby improving oil flow, improve the "three high" crude ol mining efficiency, it can also be used for water, wax ,red sand and layered oil, while because of steel degree, the ability to withstand high torque, so it's also widely used to drive the screw. Main features:1,Increase the effective plunger stroke, improving pump efficiency and increase oil production.2,To reduce the number of workover and wash well, avoid high condensate, high wax plugging wells, and other accidents.3,reasonable structure, reliable sealing, and it's mechanical performance can arrive to the level of class D.
We have all kinds of advanced testing and inspecting equipments covering the material testing, chemical detection, mechanics testing, nondestructive testing, fatigue test, and others testing customer required. With these advanced equipments, it is easier for product optimization, performance testing and quality control to ensure the stability and promotion of products.Sucker Rods
