Publishdate:2021-05-24 Views:414


Micro-High Chromium Steel Alloy /Micro steel  Ball description

It is widely used in making Hydraulic fracturing proppants for the oil and gas industries and Graphite Mining industries .

Proppant is used to keep the fractures open preventing the fractures from closing due to overburden pressure after the Hydraulic fracturing work is completed. Proppant provides a high-conductivity pathway for gas ,oil , hydrocarbons to flow from the reservoir to the well.
