Tungsten-Plated Sucker Rod

RockySea Petro Tungsten-Plated Sucker Rod



With 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 plating solution on the basis of electroplating and electroless plating, so that the particles are deposited together with the coating, and the coating has the characteristics of both metal coating and particles.

After two years of dedicated research and development, RockySea Petro has successfully developed a new type of nickel tungsten composite plating technology, which is widely used for surface treatment of tungsten-plated sucker rod.



The following is the metallographic comparison of composite plating(left) and traditional tungsten plating(right).



Based on the advanced nickel-based technology, RockySea Petro composite plated products take the lead in China.

We adopted advanced fourth-generation nickel-based tungsten plating technology.Compared with conventional anti-corrosion methods such as liner and internal spraying, tungsten plating has the characteristics of high hardness, high anti-corrosion, strong coating adhesion, and high working temperature.

Features



Application 
The tungsten-plated sucker rod of RockySea Petro is especially suitable for high water cut oil wells with high corrosion and prone to eccentric wear.

  • The max working temperature can reach 300℃.
  • Strong coating and plating adhesion
  • High anti-corrosion.Ni-W alloy has excellent corrosion resistance which leads the coating has no pinholes and microcracks to increase the protection ability.
  • High wear resistance. The hardness of the coating is 940-1100hv, and the wear resistance of the coating is greatly increased, which is far better than the chromium coating.
