n: a device that secures the end of a bend in the wire rope to the body of the wire rope. A typical safety clamp consists of a U-shaped bolt that is fastened to the wire rope with a saddle-shaped base. Two nuts on the base thread onto the U-bolt to secure the clamp to the rope.

n: hardness developed in metals as a result of cold-working.

n: a three- or four-wire connection, resembling the letter Y, used in three-phase circuits alone or in various combinations with delta connections.

n: a biopolymer produced from a particular strain of bacteria on carbohydrates that produces large increases in apparent viscosity while maintaining fairly good control of filtration.

ultra high pressure high temperature.

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.

The filtration value of the crossing point of the direct ration relatio line and the filtration value line is called zero error.

a brine made of salts of zinc, usually very dense.
