Industrias

La tecnología de pigging es ahora una parte integral de muchas áreas de aplicación diferentes. Aquí, en la mayoría de las aplicaciones industriales, se bombean medios líquidos y se utilizan tuberías como medio de transporte. Utilizando la tecnología pigging en la siguiente etapa del proceso, el producto se transfiere fuera de la tubería de forma rápida, casi completa y siempre rentable. Aquí, los requisitos de cada sector son diferentes, pero las soluciones de pigging son similares. A continuación encontrará más información sobre las diferentes industrias y sistemas de pigging específicos para completar el proceso industrial.

Industria Química

La manipulación de productos en la industria química requiere una tecnología superior. Debe evitarse la contaminación cruzada y el endurecimiento del producto. Gracias a la tecnología pigging se pueden implementar estos altos estándares de calidad. Unos pigs con buena resistencia química y un rendimiento de raspado optimizado son tan necesarios como las estaciones casi sin recovecos. I.S.T. ha desarrollado sistemas de raspado para satisfacer muchas demandas diferentes de la industria química. Estos sistemas garantizan la fiabilidad del proceso en muchas instalaciones industriales.

I.S.T. atiende a los siguientes subsectores:

Lubricantes y Aditivos

La tecnología de pigging industrial tiene su origen en la industria de los lubricantes. Aquí las ventajas del pigging se descubrieron muy pronto y por ello su gran implantación en muchas plantas industriales. Las condiciones parael pigging en este sector son ideales. En esta industria, las posibilidades varían desde simples sistemas manuales hasta construcciones complejas que conectan numerosas áreas de la fábrica como una red mediante tuberías. Hemos tenido éxito desde nuestros orígenes en este campo, durante más de 40 años.

Productos alimentarios, bebidas y tabacos

Los productos susceptibles de envejecer o deteriorarse requieren una instalación de producción que sea fácil de limpiar. Los componentes y equipos se diseñan teniendo en cuenta los requisitos higiénicos para un procedimiento de limpieza sin residuos.

Un sistema pigging diseñado específicamente para cumplir con estos requisitos puede reducir significativamente los tiempos de limpieza. La secuencia de limpieza a menudo se completa en minutos, lo que facilita la utilización completa del producto en la tubería. Esto conduce a ahorros de costos a través de menores pérdidas de producto y una rápida disponibilidad del equipo después de secuencias cortas de pigging/CIP.

I.S.T. atiende a los siguientes subsectores:

DN150-300 - Big nominal sizes

Piggable connections for ship loading and unloading of all products which can be pumped

Pigging system for ship loading: When designing this pigging system various transport ways were considered in order to guarantee a flexible use of the system. In a line which is 1,2km long 46.000 litres of fuel are saved through pigging.

Pig loading and unloading station in a trasport line in DN 250: With the pig loading and unloading station and easy change of the pig is possible. In combination with the piggable ball valve the pig change can be done without any pressure. The change chamber is openend by a lock with safety device, the pig is located through its integrated magnet and the pig sensor at the station. With pig sensors, proximity switches and pressure sensors these single process steps can be controlled by a process control system.

Pig loading and unloading station in the chemical industry

Commisioning of a pigging system in a port area

Main characteristics of the lip pig are high durability and suitability for multi-purpose applications

The T-port valve is a proven branch principle in larger pipelines

For transfer of the media the valve can be passed and pigged without pockets

Pigging system for ship loading. The products are transported from two tank fields and are pigged to the ship loading point. With this system the pig is removed at the receiving side and inserted at the launching side.

Skid with pig changing station and additional piggable ball valve as safety device

Proven seal principle as in the product range cylindrical valves

The T-port valve is arranged in a T-design. the internal cylinder allows for a pocket-free product transport and pig passage through the valve. In switched condition the product flow is open to two sides, the third connection is closed by a cylinder. In this position the product is pigged to the outlet. The pig is caught by a pig stop device in the cylinder. Thus it is possible to reach a T-branch in a pipeline without using a two pig system.

Functional description: The pig changing station is mounted outside and separated from the pipeline with a ball valve. Thus a safe pig exchange is safeguarded.

In many industries the supply of larger raw material quantities cannot be met directly at site, this means there are often long distances to be covered. Raw materials which have to be stored are often delivered by ship and the tank field for storage is far away. Here the optimum transport means is a pipeline system. With help of a pigging system this process can be optimized so that the pipeline is completely emptied, product mixtures are avoided and there are no costs for disposal of residual products.

  • No product in the pigging system after pigging process
  • No product ageing due to products remaining in the pipeline
  • Minimisation of risks by pipeline emptying
  • Complete product availability
  • Reduction of investment costs thanks to multiplex use of piggable pipelines.
  • Reduction of costs for cleaning and disposal by complete pipeline emptying
  • Reduction of process time for pipeline emptying
  • Reduction of environmental impact by avoiding rinsing media and product disposal
  • Sustainable process method for protection of natural resources
  • Avoidance of cross-contamination between different media in a pipeline
  • Closed one pig system
  • Pressure free pig exchange
  • Locking device at the changing station with safety device
  • Compact design, arranged on a skid
  • Low maintenance
  • Possibility of automatic or manual operation
  • Maximum reliability and protection against leackages and accidents
  • Easy and quick seal replacement
  • Preferrential dimensions for pigging systems are described in our "Recommendations".
