· Products are manufactured according to API 11B Standards.
· Farsight delivers API sucker rods ranging from 5/8” to 1-1/4”, with lengths of 25 or 30 feet. Different steel grades are available, depending on the type of load and the corrosion level in the wells.
· GRADE D CARBON: Designed for non-corrosive or effectively inhibited wells with moderate loads.
· GRADE D ALLOY: Designed for moderate to high loads in non-corrosive or effectively inhibited wells.
· GRADE KD: Designed for corrosive wells where inhibiting is recommended, with moderate loads.
· GRADE D SPECIAL: Designed for corrosive wells with high and moderate loads where inhibition is recommended.
