Dura-Bar continuous cast iron is an ideal material for many oil industry applications, including those used in drilling and fracing. For example, Dura-Bar G2 gray iron is used for bridge plug parts because it has the required strength to seal a well, but can be drilled out easily when the time comes.
Most parts will be specified as ductile or gray iron already, often currently being made as castings. Following are some common categories and parts within them:
Drilling:
Bridge plug/cement retainers, including upper and lower slips that anchor the plug, a tapered plug mandrel, and a sealing element set in a casing
Wickers (breaks apart) from 1018 (carburized and hardened) or gray iron
Cones (drillable with a rock bit) from gray iron
Retainers: ball, key (upper and lower)
Slip rings (interpiston lock housing, as it compresses it ratchets) from 80-55-06 ductile or gray iron
- Slips, cones and lock rings can make up a plug valve insert
Charge case perforating guns
Oil pump and compressor:
Actuators
Casing centralizers
Compressor sleeves
Gas line couplings
Heads
Manifolds
Pistons
Valve bodies
Valve seats, ball seats, spring seats (fit into the ID of a ball seat)
