Product Description
Our ceramic liners are made by advanced isostatic pressing technology. The alumina content is 95%~99.8%. The product is mainlyused in petroleum drilling and geologic exploration, especially in dreadfuldrilling conditions and developing ocean oil and natural gas, etc. It makeservice life increased by 5~10 times of metal liner, and make drilling costsdecreased more than 50%. The ceramic liner has the high abrasionresistance, corrosion resistance, high pressureresistance,high temperature resistance, and high hardness, etc. This itemtechnology has filled the gap at the absoluteleading position
