Abstract: A CEMENT COMPOSITION FOR LINING STEEL PIPE BY CENTRIFUGAL CASTING OF A SLURRY OF THE CEMENT COMPOSITION COMPRISING SAND PARTICLES OF UNIFORM PARTICLE SIZE TO AVOID GRADATION OF THE SAND DURING THE CENTRIFUGAL CASTING OF THE LINING AND PORTLAND CEMENT IN A CONCENTRATION ADEQUATE TO JUST FILL THE VOIDS BETWEEN, AND WET THE SURFACE OF, THE SAND PARTICLES. A SMALL AMOUNT OF FLY ASH POZZOLAN IS INCLUDED IN THE COMPOSITION TO INCREASE THE FLUIDITY OF THE STIFF SLUDGE BY MIXING THE CEMENT COMPOSITION WITH WATER USED IN THE CASTING. AFTER CENTRIFUGAL CASTING OF THE LINING IN THE PIPE, THE PIPE IS STORED IN AN UNDISTURED CONDITION UNTIL INITIAL SET BEGINS AFTER WHICH THE LINING IS STEAM CURED AND WATER FLOODED.

Abstract: An improved calibrator for moisture analyzers is provided. A flow of clean dry carrier gas into two streams, one of which passes through an improved saturator bomb, wherein it is completely saturated with water, and then this saturated stream is mixed with the other dry stream to provide a controlled wet stream for calibration. A capillary restrictor is used to control one of the streams. The invention utilizes a simple mathematical relationship for water concentration, means to vary each of the parameters in the relationship independently of the others, and means to simply determine values for the parameters, whichever are varied during a calibration.
