A 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 down-hole components of a reciprocating piston pump installed in an oil well.
A polished rod is the top-most rod in a rod string. These rods come in various lengths and sizes. Polished rods are made of various materials, including carbon steel, stainless steel, and monel.
API 11B Sucker Rod Coupling, The sucker rod coupling have the same box thread size in each end are used for connecting sucker rod and/or pony rod, and/or sinker bars with sucker rod threads.The polished rod coupling have the same box thread size in each end are used for connecting polished rod and/or sinker bars with polished rod threads to the sucker rod string.
The hollow sucker rod is a special sucker rod designed for oil extraction of high pour point, high viscosity and high wax content. It is combined with threaded joints, sealing and rod body. The rod body is made of seamless steel tube and the threaded joint is connected with the rod body through friction welding and heat treatment. The pin thread is formed by roller.
API 11B Sucker Rod Coupling, The sucker rod coupling have the same box thread size in each end are used for connecting sucker rod and/or pony rod, and/or sinker bars with sucker rod threads.The polished rod coupling have the same box thread size in each end are used for connecting polished rod and/or sinker bars with polished rod threads to the sucker rod string.
Continuous Sucker Rod: A grade D performance, this Sucker Rod with special designation of SM, SMR, SU, and SRU. A non-jointed high quality of Alloy Steel with elliptical or round section, this suker Rod is high strength with flexibility and solderability to significantly reduce the failure rate of most Sucker Rods, reduce attrition rate of Tubing, and and to improve the efficiency of well production.
Pony Rod is a long steel rod used for joining downhole components of a piston pump with the surface in an oil well. The rod is threaded from both sides and is commonly available in three variant diameters of 3/4, 7/8 and 1.
Sinker bars. A sinker (or heavy-weight) bar is normally a special steel bar or large-diameter sucker rod placed directly above the downhole pump. ... Sucker-rod buckling will cause excessive rod- and/or coupling-on-tubing wear above the pump.
Hammer union is a connection common in oil industry containing two joints coupled by a threaded nut. Hammer unions are designed to join the mud tanks quickly without having deal with the flange connections at all.
Centralizer are designed from our experts and provides efficient functionality. These are checked on a regular basis and that are used in different industrial applications. The offered zinc spiral vane solid rigid centralizers are simple and convenient, extensively used for rough and fine polishing of metallurgical specimens.
Drill Collars are extra-heavy integral tools used to concentrate weight onto the drill bit so as to produce sufficient force for the drill bit to break rock efficiently while drilling. They are made of AISI 4145H modified steel and are connected between drill pipes and drill bits.
Casing Spacer Spool is the very important equipment used in the drilling process, casing spool can control the wellhead pressure, casing spool is often flange ended on the top of the casing head and connected with the bottom of the tubing head then become a part of the wellhead system of the oil well.
Rotary subs are made from AISI 4145H modified quenched and tempered material. In addition, it is designed and manufactured according to API specifications as well as with API monogram A short sub assembly used to enable two components with different thread types or sizes to be connected.
Sucker Rod Pump: API specifications as well as with API monogram A short sub assembly used to enable two components with different thread types or sizes to be connected.
