On-stream Disassembly Pig signalers, which mainly consist of base, pig valve, mechanical body, vent valve, adaptor ring, gauge outfit, and safety template, are important equipments in ball passing process flow. They are fixed on the pipe and used to inspect whether the pig has passed the test point or not. The advantages are acid and alkali proof, corrosion proof, structural explosion-proof, visual and credible indication, and dismountable with pressure which is convenient for maintenance in operation.
