RockySea Petro Tungsten-Plated Sucker RodWith the increase of working time, conventional sucker rods are prone to corrosion and eccentric wear during operation, and are not suitable for high-strength or harsh working conditions. To solve the eccentric wear and corrosive problems in oilfields, RockySea Petro developed various anti-corrosion and anti-abrasion products, including tungsten-plated sucker rod.Description Composite plating is to add insoluble particles (such as ceramic particles) to the plat

Flexing: An optional outside profile can be machined to reduce the collar rigidity if required.
Internal bore treatment: This option generates a compression level of at least 60,000 PSI at a given depth. This provides the collar with an excellent resistance to stress corrosion cracking.
Pin stress relief groove and box boreback: An pin stress relief can be used on all drill collars and downhole tools. It is a recommended option in situations where fatigue can occur as a result of bending. By removing unengaged threads in the high stress areas of the drill collar connection, it is less likely to crack due to fatigue because the bending will take place in the area of the connection with smooth surfaces that are free of stress concentrations.
Optional slip and elevator recesses are available to improve handling and safety. These two features can be used together or separately.
