Washover pipe accessories:
Drive Sub
Drive Sub provides the crossover connection between fishing string and the washoverpipe. Each sub is machined from high-grade alloy steel and heat treated to provide maximum strength and durability.
Lift Plug
Lift Plug is designed to provide an economical method of handling washover strings. It is available in all thread types and sizes to support all connections. In addition, it has sufficient shoulder diameter to support and ensure proper handling of the washover string.
Washover Safety Joint
Washover safety joint is manufactured to provide safe and easy make-up and release of washover tools whenever disengagement of washover string is necessary. This dependable, rugged tool is designed for tough field applications to transmit torque in either direction when placed in the washover string.
Rotary Shoes
Rotary Shoes are manufactured from specially heat treated alloy to provide ultimate toughness and durability. They are used to cut and create a clearance between the fish and the wall of the well bore.
