Stainless Steel Polished Rod Coupling For Oilfield Sucer Rod Industry Durable
Products Description of Sucker Rod Coupling
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.
