Jan 19, 2018

The appearance quality and dimension of the railway fittings.

(1) the steel rails after rolling should be straight, and should not be significantly bent and twisted.

For the local bending and torsion of light weight rail and its correction deformation, the inclination of the rail end face should not exceed the standard.

(2) the surface of the rail shall be clean and smooth, and no cracks, scars or scratches shall be allowed.

The end face must not have the shrinkage mark and the interlayer and so on.

For the defects of the overall surface of the light and light, and the degree of their geometry, they must not exceed the standard.

The length of the rail and other geometrical dimensions and tolerances are provided by the relevant standards in the "8".
