Oilfield API 11B 2ft 3ft 4ft 5ft 6ft Grade D Sucker Rods Pony Rod
Sucker rod is the common equipment in the oil extraction. It is
manufactured through many process including the testing,
straightening and forging. The sucker rod is placed between the
polished rod and oil well pump. To deliver power. Sucker rod is
manufactured from high quality carbon steel and alloy steel, which
is conform to the API Spec 11B standard. Sucker rod has various
types including the common sucker rod, hollow sucker rod and FRP
sucker rod. Commonly we use the sucker rod coupling to connect the
sucker rod. The sucker rod also has various specs to fit different
environments and applications.
One piece of sucker rod and one pieces of sucker rod with coupling
with explanation on it.
