Steel Sucker Rod
Grade C sucker rod is made from fine carbon steel. It is featured by mid-strength, good plasticity, toughness, corrosion resistance. It is suitable for sour medium environment where it is no susceptible to sulphuric stress cracking.
Grade D sucker rod is made from fine alloy steel, featured by high strength, better plasticity and long service life after heat treatment. This product is suitable for no-corrosion or ligh-corrosion environment oil-well widely.
Grade HL and HY sucker rods are super-high strength sucker rod, having the same size and main parameter as grade D sucker rod, but their strength is capable to reach 966-1195 Mpa. Grade HL and HY sucker rod are suitable for the deep oil-well or big-pump capacity oil-well.
Grade K, KD and KH sucker rods are made from fine Cr-Ni-Mo alloy steel containing different amount of Ni. They possess more powerful anti-corrosion function. The products are suitable for strong corrosion oil-well, with depth of shallow, middle and deep respectively.
Steel Sucker Rod Selection Guide
Grade C: Designed for light-to-medium loads in shallow-to-medium depth wells and non-corrosive or effectively inhibited corrosive well fluids. Grade K: For light-to-medium loads in shallow-to-medium depth wells where corrosion is a problem and must be effectively inhibited.
Grade D: For heavy rod loads or deep wells in mild-to-medium corrosive well fluids that are effectively inhibited against corrosion.
Grade KD: For medium-heavy rod loads or deep wells in corrosive well fluids that are effectively inhibited against corrosion attack.
Grade HL and HY: Designed for heavy-extra heavy loads at any depth in corrosive fluids that are effectively inhibited against corrosion attack. Grade KH: Designed for extra heavy loads at any depth and fluids that are effectively inhibited against corrosion attack.
