A pony rod is a short section of this sucker rod that is usually positioned below a polished rod to make a desire links for rod string. They are actually manufactured using the exact same type of chemical properties, dimensions, diameters and tolerances as a sucker rod. Pony rods are meant to meet many needs of internal pumps. Consider them to be a part of machine and stock, as well as accessories for service pumps. Pump and supply companies can supply you with the parts needed for all major pump manufacturers. A complete list of those parts includes; pony rods, plungers, pump expendables and more.
Pony Rods Are Used in Oil Wells
Typically, a pony rod which is threaded on both sides, is a diameter of three variants of ¾, 7/8, and 1. It has a high tensile strength and has been designed to meet diverse challenges including corrosive environments and high loads while still retaining full control in regards to rod friction. This type of rod can provide you with unparalleled performance for deep oil wells.
The Pony Rod Is the Key to an Artificial Lift System
When it comes to an artificial lift system, a pony rod is one of the key constituents that can undergo optional heat treatments and still increase fatigue resistance. The three grades of rods used in oil wells include grade D, grade C and grade K. What separates each grade, is the precise tensile strength. Grade C is the particular grade with maximum tensile strength at 115,000 psi. Grade K consists of a tensile strength of 140,000 psi. A pony rod is put adjacent to a polished rod within a rod string so it can handle and prevent the string from falling down. They are not meant to be used for the purpose of load carrying.
