Detailed Introduction
      Alloy white cast iron oil pump cylinder sheath is a new high and new technology product (patent no.: ZL-00258662.2) developed and manufactured by our company.
      
      The new material-alloy white cast iron adopted in the product is the matrix material made by adding certain proportion of chrome, silicon, manganese and other elements through centrifugal casting based on repeated research and development, and its hardness could reach HRC62-64 after repeated special treatment. Because the new material is adopted in the product with unique fabrication method, hence it could perfectly solve the problem of synchronous and dual increase of corrosion proof and abrasion proof and could reduce the phenomena of dregs, hole shrinking, and so on, and it’s an ideal replacement product for the existing oil pump cylinder sheath. The abrasion prevention effect is particularly obvious while using the oil pump cylinder sheath manufactured by our company in areas with large sand content and high content of sulfur and chlorine ions in the wells and large temperature variations of wells. The 744 deep well oil pump cylinder sheath manufactured by our company with new material has been test used by Jilin Oilfield and Daqing Oilfield with wonderful effect. No.108-1 Well of Jilin Oilfield used the oil pump cylinder sheath manufactured by our company on October 2, 2001, and the sheath is still in service for the well, with the service term more than 2 years, which has greatly extended the pump inspection period. It could also reduce the pump inspection cost, save oil extraction cost with considerable economic benefit and social benefit besides the increase of unit well output.
     The technical dimensions, processing precision and various indexes of the product have reached the standard of SY/T5059-2000.
