The sucker rod is a type of long and thin steel rod used to connect the pump made a low tempering carbon alloy steel made, which is an important part of the production device with a rod pump. The sucker rod string is made up of several sucker rods connected by a collar, which is connected in the oil pipe with an internal thread hoop and extends to the piston in the underground oil layer to pump oil through reciprocating motion.
Conventional sucker rod production technology is simple, low cost, small diameter, a wide range of applications, accounting for more than 90% of rod pumping Wells. Conventional steel sucker rods are divided into four grades: class C, class D, class K, and class H. Class D is the most commonly used grade sucker rod, steel sucker rod for medium and heavy-duty oil Wells. Class D sucker is made of high-Cr-Mo alloy structural steel AISI 4130, which is characterized by high strength and plasticity, is applicable to non-corrosive or slightly corrosive environment of deep wells. The most commonly used single length is 7.62 or 8 and 9.14 meters.
