Disassembly of a chemical syringe under pressure is a part of the chemical injection system. There are three kinds of chemical Syringes: flange connection, welded link, and pressurized disassembly. They can all inject reagents into the pipeline. However, the difference is that the pressure disassembly chemical syringe can be disassembled and installed when the pipeline works normally.

The flange-connected flag-type mechanical ball-through indicator is composed of a mechanical contact body and a flag indicator head. It has the characteristics of intuitive indication, automatic reset of the mechanical part, and manual reset of the display part. The indicator can be displayed normally when the pipeline passes through the pig in the forward and reverse directions. So it can be positioned on the pipeline, and the passage of the pig in the pipeline can be transmitted through the mechanical structure to provide the operator with information and guide the process flow conversion.

Medium-Density Bare Foam Pig is made of medium-density foam. The bottom of the utility model is coated with polyurethane elastomer. So they are used to dry the pipe and clean loose debris in the pipeline.

Vertical Quick Opening Closure of EMT has very good quality and great service. It has first-class sealing and very convenient operation mode. Before the lock plate and safety bolt are installed, the Vertical Quick Opening Closure cannot be boosted and cannot be put into use.

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 lit. Most pigs need pipeline pressure relief and shutdown, and the economic loss is immeasurable. Andwe provide a ball indicator with pressure disassembly that is easy to disassemble and maintain. To solve the problems raised in the above background technology.
