It be used to join internal upset drill pipe.It has maximum circulating opening of internal upset section .

n: in multiple packer completion, a device, made up just below the uppermost packer, that switches tubular fluids to the annulus and annular fluids to the tubing above that packer. Also Y-SUB called a Y - block.

n: on a mobile offshore drilling rig or ship, the angular motion as the bow or stern moves from side to side. v: to move from side to side (as a ship).

The slang of centrifugal pump at oilfield.

n: see hydraulic control pod. yield n: the number of barrels of a liquid slurry of a given viscosity that can be made from a ton of clay. Clays are often classified as either high- or low-yield. A ton of highyield clay yields more slurry of a given viscosity than a low-yield clay.

The volume occupied by one sack of dry cement after mixing with water and additives to form a slurry of a desired density. Yield is commonly expressed in US units as cubic feet per sack (cu. ft./sk).

a measurement applied to clay dealing with the number of barrels of a set viscosity fluid than can be made from a given quantity of clay.

n: the maximum stress that a solid can withstand without undergoing permanent deformation either by plastic flow or by rupture. See tensile strength.

the resistance to initial flow of a fluid or stress required to start fluid moving.

The stress on a material at which the first significant permanent or plastic deformation occurs without an increase in stress (NACE).
