Special ultra-high pressure glass blasting disc for petroleum cementing. After blasting, the glass is in powder form and the particles are uniform. Petrochina Bohai Drilling, Great Wall drilling, Jiangsu Oilfield Overseas Project Department, Xinjiang Karamay, Tarim Oilfield, Shengli Oilfield, CNOOC and so on have been applied in large quantities.
Special note: quartz glass and tempered borosilicate glass cannot meet the demand of high pressure blasting. The basic mystery is that the glass produced by the chemical composition of glass is not enough to produce high enough mechanical strength, so it cannot meet the use of precise blasting.
The bending strength of quartz glass is 35-50mpa, and the bending strength of borosilicate glass after tempering is 90-150mpa.
The bending strength of blasting discs produced by our company can reach: LCG-5016=510Mpa(for use below 40Mpa), LCG-1935=610Mpa(for use between 40-120mpa),we can offer you good products according to your requirement.
