Automatic Operation Electric Large size and High pressure carbon steel quick opening closure for pressure vessel

Pig launcher and receiver traps are custom manufacturerd for sub-sea,off-shore and onshore applications.

    Pig launcher is used to launch the pig into the pipeline, and pig receiver is used to receive the pig  after

they have made a successful launch. A launcher is located at the upstream end of the pipeline to launch the

pig into the pipeline, A receiver is located at the downstream end of the pipeline  to remove the pig from the

pipeline.

    The choice of these traps will depend on the type pf pig to be run and pipeline design conditions.

 When welding the blind flange and the cylinder body, the current is not too much, if you overheat the blind plate, it will out of shape.

 The  person who  using  the blind flange, must know the structure and the operation procedures of blind plate. Before  open  the blind  flange cover, you must first open the air valve to make sure the pressure in the pressure vessel drop to zero, then open the blind flange.

 When  pressurized to the pressure  vessel, you must first installed the releasing plate, then  press-urized and put into use. After the  pressure vessels  are  put into use, knock  the main pressure components  and collision is  forbidden. The transmission system of the blind plate and screw locking  device must  always apply oil to prevent rust. Appearance must be intact and clean.

On a regular basis to check the blind flange of main pressure parts (such as blind plate,tube surface) if found it heavy corrosion or crack, must find out the reason in time,and handle the question  properly.After use, to inspection and clean the gasket and the seal groove, and paint yellow glycerin, in order to prevent bad sealing.
