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.

rotomolded water tank

Analysis of mechanical resistance of water tank  produced by rotomoulding.

Rotomoldeo M & M needed to change the functionality of one of their products: water tank. It was hoped that the same could be buried preserving the dimensional characteristics, mechanical and functional resistance (opening of cover). Finite element analysis of the structural behavior of the cistern when buried in sand.

We analyzed 4 design alternatives, which provide the necessary structural rigidity and do not distort the original design of the same. The deformations that the model showed were validated through a control tank.

Results:

- the use of the numerical tool allowed the analysis of variants of designs without the need to construct matrices and to resort to trial and error, representing a cost savings of 70% of the design process and considerably reducing the time of the same.

- a robust design was obtained that allows to underground the tank avoiding the collapse of the same and conserving the functional characteristics (opening of the cover).

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.
