Product Details

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.D is the most commonly used grade sucker rod, steel sucker rod for medium and heavy-duty oil Wells. The most commonly used single length is 7.62 or 8 and 9.14 meters. The other grades are:


Grade C sucker rod: Used for shallow Wells and light loads. (not often used)

Class K sucker rod: Steel sucker rod for corrosive light to medium duty oil Wells.

Grade K and D sucker rod: Steel sucker rod with the corrosion resistance of grade K sucker rod and mechanical properties of grade D sucker rod.

Class H sucker rod: Steel sucker rod for heavy-duty oil Wells.
