Industrial measurements, Cabot Corp.

The job consisted in the execution of industrial measurements in order to understand the behavior under the thermo-mechanical stresses in the pipeline, during the actual operating conditions of the plant.

The manufacture of Black Smoke, requires circulating combustion gases through a pipe length of 20 meters and diameter 48 “(1200 mm). The walls of the stainless steel duct can reach temperatures close to 600 ° C.

In strategically selected points, thermocouples were placed that recorded the thermal gradients. The duct expansion joint was instrumented with displacement sensors, allowing a measurement of thermal deformations.

During a period of three months, temperature and displacement measurements were continuously measured every 3 seconds. The Acquisition Equipment and the sensors used are the property of TECDESIN.

The work included the analysis, interpretation of the measurements and recommendations and proposals for improvement within the Cabot plant.

Provisión de un sistema de resistores para calentar un fluido sometido a muy alta presión

cliente: Tenaris Confab - Brasil.

Determinados productos tubulares son verificados a una temperatura elevada, mientras se le aplica una presión externa.  La norma API5C5, normaliza este tipo de pruebas para los Tubing y Casings utilizados en los pozos de petróleo.

Se trabajó en la modificación de las instalaciones existentes, para poder cumplir con las últimas modificaciones de la Norma: Calentar muestras tubulares a una temperatura de 180°C y con una presión externa de 20.000 psi.

El trabajo demandó una fase de diseño, una fase experimental y la puesta en servicio.

El diseño contempló el desarrollo de resistencias blindadas para soportar grandes presiones.  El ajuste de conectores con sello metal-metal para el pasaje de la alimentación eléctrica.  La confección de un modelo de elementos finitos térmico-fluidodinámico.  El desarrollo de soldaduras especiales.

Durante la fase experimental se ajustaron tolerancias y se delinearon las prácticas operativas.

La puesta en servicio se está llevando adelante en las instalaciones de Confab.
