Pig Signaller With Flange

Description

Description
A Pig Signaller is a necessary piece of equipment in the technological process of ball passing and descaling of long-distance pipeline. It can accurately show whether the pig has passed a predetermined place. This can assist in the successful completion of pigging and sweeping. At present, the ball indicators used at home and abroad basically meet the requirements of pigging and sweeping. But it is troublesome to maintain and repair it. Most pigs need pipeline pressure relief and shutdown, and the economic loss is immeasurable. And we provide a ball indicator with pressure disassembly that is easy to disassemble and maintain. To solve the problems raised in the above background technology.

Before pigging, a signal transmitter needs to be installed on the pig. This is to detect the time when the pig passes through the pipeline. When the transmitter approaches the signal receiver, the receiver will alarm. Through this principle, the receiver can be arranged on the ground above the pipeline to determine whether the pig passes. The operator then opens the blind plate of the launcher. After opening the blind plate of the launcher, grease the launcher and replace the sealing rubber ring. This is to ensure that the launcher does not leak after charging.
