文档介绍：Manual of BAODA Oil Well Pipe Chapter 1 Introduction Wuxi Baoda Tubular Goods Producing Co., Ltd. founded in March 2001, presently has three lines of producing Oil well pipes and casing .It mainly processes oil well pipes, coupling and pup-joint in all size and several grades with outside diameter from Φ ~ Φ . Annual capacity is up to 80,000 tons. pany carries out management according to ISO9001: 2000 and API Q1 standards. The strength of several experienced specific technologists provides our products with powerful technology support. Oil well pipes of BAODA are widely used in the exploration of land oil field and pipe convey, being the safe and durable products. To acknowledge the support to WUXI BAODA from petroleum industry and mass users for years, make the products have best performance in uses and help oil field technicians know the products deeply; pile the BAODA Manual in particular. Users are advised to read the manual carefully when choose, transport, load and unload, store, inspect and repair our oil well pipes. Oil well pipes made by BAODA are mostly used in the process of oil field development for the task purposes of oil extraction, fracturing, acidification, affuse, gas injection and well workover. The body stocks of oil well pipe of BAODA adopt the technologies of electric steel making, vacuum degassing, secondary steel making processes, which make products with ponent and good metallurgy quality. Roller trio skew rolling and 12- frame tension reducing technology can guarantee the good shape, high precision dimension and nice mechanical properties; finishing and nondestructive technology (ultrasonic and eddy current testing) can assure the excellent exterior and interior quality; moreover, the parameter of screw thread made by high precision numerical control lathe is 30% stricter than API standard, which leaves the properties of anti-thread gluing, anti-slipping and sealability up to set values of API standard. The oil well pip
