Magnetic particle inspection, also called MPI , or MT is a non-destructive test(NDT) process for detecting surface and shallow subsurface discontinuities in our heat treatment steel round bar materials. In order to improve our produce quantity, our wind turbine foundation system anchor bolt, roof support system anchor bolt, round bar, high duty stud bolts and many other materials need this test as per clients demands.
