BAR-SP LINE
CYM Materiales designs and manufactures shot peening machines for sucker rods used in the oil and gas industry. The BAR1 and BAR2 machines process API sucker rods up to 30 ft long in diameters from 5/8" to 1½", inducing compressive residual stresses that significantly increase fatigue resistance in service, reducing rod failures in the well and extending service life. The machines are adaptable to shorter rods depending on project requirements.
The BAR1 machine is equipped with one centrifugal blast wheel and the BAR2 with two blast wheels in line, doubling production capacity. Rods are processed one at a time on a double-cone (devil) roller conveyor. Both models include turbine RPM control from the HMI with electric actuator for automatic positioning of the control box, abrasive flow regulation from the HMI and shot curtain formation system with differential pressure control.
With two BAR1 or BAR2 machines in line it is possible to perform double shot peening: the first machine works at high intensity and the second at low intensity, a process that maximizes compressive residual stresses on the rod surface. CYM Materiales complements the shot peening machines with complete rod handling systems — racks, conveyors and feeders — and integrated dip paint lines.
Applications
CYM Materiales BAR1 and BAR2 machines cover the main surface treatment processes for sucker rods: single shot peening, double shot peening in line, dip painting and integrated rod handling systems. The choice of model and configuration depends on production volume, required intensity level and integration with the customer's manufacturing line.
