SHU

Sludge trap (SHU-1) is designed to prevent obstructions and to provide triggering of mechanical and universal firing heads. Circulating holes provide connection between the production tubing and the casing-formation annulus.

Features and advantages:

  • glass disc unit of TR serves as a barrier for rubbish, but it doesn't make difference of pressure in PT or casing-formation annulus, and it doesn't retain fluid;
  • the total surface of TR circulating holes is much larger than the flow area of TR;
  • ease of assembly/disassembly.
