We consider the principal methods of nondestructive testing of drilling and blowout preventer equipment: the capillary (penetrant) method, ultrasonic flaw detection, magnetic particle flaw detection, eddy-current flaw detection, the acoustic emission method, and hardness and strength testing.We...
The various aspects of reconstruction of a pipeline in order to ensure safe transport of both liquid and gas hydrocarbons are considered. We give indicators of the consequences of explosive events and the zones of toxic damage in a possible failure of the pipeline when transporting condensate or...
Research data for five types of gland packings are reported. Relationships are shown with due regard for the number of loadings and the number of packing layers: relative deformation of the packing due to unit load, unit load on the packing due to its relative deformation, and compression and...
Theoretical principles are presented for the ultrasonic effects on the electrocoagulation treatment of effluents to remove surfactants (SA). Results are presented on the effects of ultrasound on the SA concentration (nonionic and anion-active compounds) during the electrocoagulation treatment of...
A new formula is proposed for calculation of the average limiting stress of a welded joint in a thin-wall cylindrical pipe or plate; this formula takes into account the magnitude of mechanical nonuniformity, the dimensions of the softened interlayer, and the depth and width of a surface defect...
Processes occurring in the sealing slit of a typical unloaded internal face seal of pump shaft are examined. Data required for designing face seals are recommended.
Technical data are presented for the following pumps: two-piston (double-acting), three-piston (single- and double-acting), and universal slush. New designs of the pumps are described.
