We are YANG QUAN RISING COMERCIAL CO., LTD based in Yangquan , China. We are member of Tradekey.com since February, 2010. Our business is related to Minerals & Metallurgy industry and we specifically deal in refractory. Please find our product details below: Oil Ceramic Proppant Ceramic proppant is the key material in low-permeability fracturing of oil and gas wells exploration. This products used in the construction of deep well fracturing, be filled to the low permeability of the rock deposits in the cracks, fracturing close to the high oil recovery operations, so that oil and gas cracked rock, support for propping fractures not close because of releasing force, thereby to maintain the high conductivity of oil and gas, not only can increase the oil and gas production output, also can extend the oil and gas wellss length of service. Our oil Proppant are divided according to the anti-crushing strength into 52Mpa (105KN), 69Mpa (140KN), and 86Mpa, (174KN) three series, according to bulk density are divided into: low-density, medium density, high-density. Product specifications are :12-18 mesh , 12-20 mesh , 16-20 mesh , 16-30 mesh, 20-40 mesh between 30-50 mesh, 40-60 mesh, 40-70 mesh and so on. grinding wheel Cutting wheel for metal, 2net, Diameter:100mm, Thickness:2.5mm, Hole Diameter: 16mm, 300pcs/CTN , Packing:26*21*11cm CBM:0.006, G.W./N.W.:14KGS/13KGS oil fracturing proppant Specification Bulk Density (g/cm3) Apparent Density (g/cm3) Close Pressure (Mpa) Percentage Of Crushing(%) Sphericity Roundness High Density 16Mesh-30Mesh >1.80 >3.35 69 � 18.0 >0.8 High Density 20Mesh-40Mesh >1.80 >3.35 52 � 5.0 >0.8 High Density 30Mesh-50Mesh >1.80 >3.35 69 � 5.0 >0.8 Unit Price/Payment: EXW/LC Origin: China Min.
