2. It is defined as ordinary product, so it is convenient to transport and store.
3. It is safe to apply for at high temperatures.

Installation of CHEM Gas Bags:
1. Gas Bags come pre-folded for ease of handling. They are held together by tape. Do not remove these because they allow the Gas Bag to inflate properly.
2. Attach a cord to the tag at the top so that the Bag can be lowered to the correct depth in the hole.
3. Squeeze the colored liquid bottle and pop it. This releases the vinegar onto the sodium bicarbonate. Make sure all the vinegar has drained onto the bicarb pouch then lower in the hole. You have about 40 seconds to get the Bag in place before inflation starts. When the Bag is tight in the hole, remove the cord with a sharp tug.
We manufacture the SANWEI CHEM GAS BAGS working for borehole diameter 90mm now.
This chemical reaction to inflate gas bag works well for small borehole diameters.
