Type 30 |
Designed for light-to-medium loads in shallow-to-medium depth wells and non-corrosive or effectively inhibited corrosive well fluids. |
Type 40 |
For light-to-medium loads in shallow-to-medium depth wells where corrosion is a problem and must be effectively inhibited. |
Type 54 |
For medium-to-heavy loads in medium-to-deep wells and non-corrosive or effectively inhibited corrosive well fluids. |
Type 78 |
For heavy rod loads or deep wells in mild-to-medium corrosive well fluids that are effectively inhibited against corrosion. |
Type 90 |
Designed for medium-to-heavy loads at any depth in corrosive fluids that are effectively inhibitied against corrosion attack. |
Type 97 |
For extra heavy loads at any depth and fluids that are effectively inhibited against corrosion attack. |
