Grouting packers

I. PRODUCTION INTRODUCTOIN

Inflatable or water filled grouting packer adapted to a wide range of B, N, H, P drilling hole diameters and other hole dia. can be customized. The packers are highly flexible and can be inflated with different fluids, durable and versatile. The deflated packer is put into the drilled borehol, then inflated with neutral gas or liquid through an inflation hose. The range of inflatable packers can be customized and rubber length depends on the work.
These single packers can be easily transformed into double packer.
II. APPLICATIONS:
1.      Pressure Grouting in Fractured or Unconsolidated Borehole or Rock Formations
2.      Water Infusion for Dust Control in Coal Mines
3.      Methane Gas Control and Collection in Mines
4.      Sealing Elements in Soil or Boreholes
5.      Water Sampling Testing
6.      Hydraulic Fracturing Testing
7.      Permeability Testing
8.      Quality Control Testing of Tubes
9.      Bore-Hole Fluid Sampling,
10.   Bore-Hole Wall Impression Testing
11.   Industrial Piping Hydro-Testing,
12.   Water Wells Repair
13.   Aquifers Monitoring

III. STRUCTURE:
It is a versatile tool for a wide range of hole sizes and depths.
Standard construction includes steel metal parts and a reinforced rubber sleeve element, rubber grouting hose, water/air inflation hose, manual water pump for supplying inflation water, straddle steel pipes, etc.
Rubber membrane reinforced
Abrasive resistant rubber
Extensible Steel fabric
All above elements, size and length can be customized
