Oilfield drilling mud pump system is the "heart", mud pump liner is important wear parts. Our introduction of foreign advanced technology, the introduction of the first national study of nickel-based alloys cylinder, improve the life of the liner, the process is: alloy extrusion process will be covered with the inner wall of the cylinder liner, a vacuum sintering technology to form sintered alloy layer of 1.5mm, material selection, high performance rare earth sintered layer nickel-base alloy powder material to add a micron carbide materials, the sintered layer evenly distributed high wear hard micron particles effectively sintered layer improves overall wear resistance, and because its tiny alloy, not organizational spalling phenomenon. Due to the formation of fine powder sintered alloy layer, combined with good strength, Rockwell hardness of the sintered layer HRC: 60-64. Wear and corrosion resistance performance rare earth alloy powder with bimetallic materials compared to the first is a nickel substrate, on this basis, due to the addition of C, Cr, B, Yb, Mn, Cu and other trace elements and rare earth, nickel matrix formation NiB, Cr7C3, Cr23C6 and other small, hard particles dispersed, effectively improving the high-temperature red hardness and wear resistance of the alloy, with excellent overall performance, the role of Yb, Mn, Cu and other elements grain refinement, grain boundaries purification, wear resistance alloys has been greatly improved, and thermal shock resistance, crack resistance is improved at the same time, high wear resistance of the alloy coating materials used life of more than 2000 hours, up to 4000 hours or so, is 5-10 times more common metal liner, and ceramic liner comparable. Wear resistance, high temperature, high strength, high hardness, not damaged, the price is far lower than the ceramic liner, the key is to improve exploration drilling progress and reduce the cost of drilling the transportation, maintenance, labor and storage. Our products have been certified by the American Petroleum Institute API7K, and in December 2014 by the German Rhine third party entity's certification, product quality have reached the international and domestic leading level, won praise at home and abroad.
