Sucker Rod- Used for High Viscosity Oil Exploitatio

Double hollow sucker rod  is a special structure which add an independent hollow channel in the inner of common  hollow sucker rod . The inner pipe of the double hollow sucker rod is made of stainless steel pipe which can ensure the long service life. Double hollow sucker rod is mainly used in the  circular heating device  for high pour point, high viscosity and high wax content oil exploitation. In the device, the double hollow sucker rod can be used combined with four-way hanging connector, circulating pump and other equipment. Brief introduction of circular heating device The double hollow sucker rod make use of the specially-made terminator to form two channel: outer channel and inner channel. Used combined with the four-way hanging connector, high-pressure rubber hose, circulating pump, and heat exchanger, the double hollow sucker rod can heating the crude oil circularly in a closed channel. Benefit from the structure of double hollow sucker rod, the heat...

Products Details Hollow sucker rod has hole in the middle and has the characters: chemicals and hot oil can be injected through the inner hole to decrease the viscosity of the oil and the paraffin deposit in the well thus the pump efficiency is increased; The smaller passage and the faster flow velocity can avoid the sand deposit efficiently while use hollow sucker rod in the sand well; Matched with the rodless pump hollow sucker rod can substitute the tubing; Hollow sucker rod can be used to drive the PC pumps as it can bear larger torque.

Products Details Ensure an efficient hydraulic seal throughout the life cycle with our array of polished rods. Standard piston steel and hard-surface spraymetal polished rods are available in lengths up to 40 ft. Manufactured to stringent API specifications, these polished rods give you the confidence that once you close the well in after running the pump, sucker rods, and polished rods, there will be no issues at the top of the string where loadings are the highest and fluid containment is a necessity.

Introduction Sinker bars provide concentrated weight above the pump to help keep the rod string straight and in tension, which reduces buckling of the sucker rods or the pump plunger.Sinker bars are made from hot rolled carbon manganese steel bar stock. Sinker bars are surface turned and have API double sucker rod pins, shoulders, and wrench flats on both ends. One end has a reduced section for elevator seating and lifting. Products Details Sinker Bar is heavier than the conventional rod. It is used at the bottom of the sucker rod string to keep the rod string under tension and reduce crooks of the sucker rod string during downward travel.

Steel sucker rod is the major equipment for oilfield. We provide grade C, D, K, KD, HL, HS and special alloy sucker rod which are made according to API Spec 11B. Grade C sucker rod is made of fine carbon-steel, featured by moderate strength, good plasticity and better corrosion-resistance. Grade C sucker rod is suitable for sour medium environment where they are not susceptible to sulphuric stress cracking. Grade D sucker rod is made of fine alloy steel with feature of high strength, better plasticity and long service life after heat treatment. Grade D sucker rod is suitable for deeper oil well in the non-corrosion or light- Steel Sucker Rod corrosion medium.
