Note 1: This drilling to be omitted for 4-hole bars. The following table is the Recommended Rail Drillings, Bar Punchings and Track Bolts for 115 RE, 119 RE, 132 RE, 133 RE, 136 RE, 140 RE and 141 RE Rails and Joint Bars. Recommended Rail Joints Match RE Rail Joints BarsĪGICO supplies other qualified rail fasteners to match all the rail splice bars offered. Deformation conforming to the tolerance limits is allowed.įor the tensile testing, samples should be selected from any two railway fish plates or joint bars representative of each heat of steel. The finished rail joints shall have no defects detrimental to their end use. The holes for installing fish bolts shall be either drilled or punched, and shall be to the centers and dimensions of the drawing designs offered by customers or made by us after negotiating with customers, subject to the tolerances. ![]() The chemical composition is determined by cast analysis. The test results also indicate that the use of noncontact lap splices may enhance the bond performance of reinforcing bars with small diameters, which was also reported in the study of Hamad. This is totally depends on customer’s requirements. The letters and figures will be rolled or forged on the outside surface of rail joint. Test results indicated that the proposed bar splice sleeve have adequate. ![]() ![]() The steel used for manufacturing rail joint bars comply with all the requirements of each standard in different countries.Įach railway splice bar can be customized and branded with figures denoting the mass per meter of rails and to indicate the manufacturer and the date of manufacture. 29) bars were tested using different sleeve lengths. The following are some useful tips that you may want to know: You can know the manufacturing process of rail joint bars here, together with more drawing designs.
