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.

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.
