Purposes for Pig Detectors

Knowing when a pig arrives at a station or plant, can provide vital information to operations and can indicate potential problems if not received on time. With so many things happening and so much to pay attention to an operator needs to have a reliable method by which he or she can know whether or not a pig has been received at a trap. That is why we recommend the use of pig detectors, which serve a critical role in tracking movement of the pig.

There are two types of detectors. The intrusive style is compatible with any type of pig, and is permanently attached to the pipe in use. Some sort of trigger device is hanging down in the pipe and is tripped by the passage of a pig, relaying either an electrical signal or a visual signal to operations. The non-intrusive kind is strapped onto the pipe, but only functions when used in conjunction with a pig equipped with a magnet. When the pig, equipped with the magnet, passes the magnetic field of the detector is activated and an electrical or visual signal is sent to the operator. SUN’s Magna Sygg is a good non-intrusive pig detector and has proven reliability. Drinkwater Products can help your company and operators determine which type of detector is the best for your particular pipeline, as well as its purpose.

A Reliable TDW Pig Sig

The TDW pig sig V is made of stainless steel and is completely weatherproofed, corrosive-resistant, and sturdy enough the handle the pigging process. Take a look at all of its features, and decide if this is a good fit for your structure.

Traditionally, a launcher and receiver are utilized during the pigging process for the release and recovery of the pig. Pig detectors are typically placed at the location of both the launcher and the receiver. Thus, an operator receives input regarding the successful start of pigging, as well as the completion.

Other detectors are generally used for pig tracking jobs and are generally used in conjunction with pingers or transmitters inserted into the pig. These transmitters emit an electro-magnetic pulse, which can be detected by a handheld receiver, and give off a beeping noise to indicate the pig is nearby. Drinkwater Products offers a full range of SPY and CDI pig tracking equipment.
