Mandrel bar

Seamless pipe manufacturing

 

Mandrel bar is the important parts in producing large diameter seamless pipe. In production the mandrel bar is under strong and complicate strength, compressing touching stress and high temperature cold-hot yield stress, so it strictly requires all the factors of steel, including chemical components, mechanical properties, no-metallic inclusion, grain size, microstructure, ultrasonic test, size precision, surface finish. The main material for the mandrel bar is H13(4Cr5MoSiV1)
