- Company Name : SD BaiRui Oil Tools Co.,Ltd
- About Us : <br> <br>API Grade Sucker Rods <br />BAIRUI?s sucker rods are manufactured according to API 11B Specifications. Currently, the Company market 3 types of API sucker rods Grade D Alloy and Grade D Special which are formulated from different alloys?AISI 4130 (Grade D), AISI 4142 (Grade D) and AISI 4720 (Grade KD). <br />Manufacturing Process: <br />1. Rod Bar <br />The incoming rod bars are inspected for any damage, fault and discontinuities.Before arranging the rod bars for production process, carry out chemical composition testing, dimensional inspection & surface quality inspection. High quality standard is maintained at various stage inspections. <br /> <br /> <br />Chemical Composition: See below table. <br />2.Manufacturing <br />Rod bars are manufactured from hot rolled alloy steel. Rod bars are machine straightened and cold drawn to the required size. The rod bar ends are hot forged according to API designed sizes. The rods are then heat treated over the full length.As per requirement of mechanical properties, the rods are normalized and tempered to the specified level or quenched and tempered to the required hardness and strength. Care is taken to achieve metallographic structure with no residual stresses in the rod.A sample specimen is cut from the heat treated material and is tested for ultimate tensile strength, yield strength and elongation. The rod is then again checked for straightness. The forged ends are properly aligned with its body. Rods are cleaned by shot-blasting to remove any scale and oxidation. The forged ends are machined on C.N.C. Lathe machines as per API dimensions and checked with API approved gauges. <br />Mechanical Properties: See below table. <br />3. Packaging and Storage <br />The sucker rods are then coated with rust inhibitors and carefully palletized in bundles for safe transport and handling. <br />Table: Chemical Composition / Mechanical Properties / Heat Treatment <br />Chemical Composition <br />AISI Grade AISI4130 AISI4142 AISI4720 <br />API Grade D D KD <br />Carbon 0.26~0.33 0.38~0.45 0.19~0.23 <br />Manganes<br><br>
