Specification: 1. Drill Pipe Wiper 2. Drill Pipe Wipers are made of specially designed rubber compound having tremendous resistance to cutting, tearing and abrasion. They are available for water based and oil based drilling mud. Designed for application.They are available for 5", 3.1/2", 2.3/8" and 2.5/8" drill pipes / tubings. 3.Size for 27/8",31/2" 5" 51/2"drill pipe 4.wiper is designed to clean casing,tubing in oilwell . Advantages: 1. high strength- Resistance, wear- Resistance 2. Resistance to high temperature 3. Absorption oscillation resistance to high speed 4. Resistance to heavy load 5. Internationally advanced quality level, can be designed to meet the specific needs. Description: Material: Butyronitrile rubber is the basic material. The inner steel skeleton is to prevent deformation. Main application: prevent drilling fluid returning from the drilling. Clear drilling fluid on the drill pipe wall to prevent the corrosion of metal. Hardness: 8 to 95 ±5 shore A ,±3 shore A tolerance specially Color: for rubber, usually black, for silicone, can be in any color as you want Machine type: 50 to 400 tons Mold/samples lead-time: For prototype mold, usually in 7days For mass production mold, usually in 2 weeks For some special molds, can be in 30 days, especially for some automotive rubber molds
