Description

Mandrel bar plays a crucial role in producing large diameter seamless pipes in modern industries.

In producing line, it have to bear strong and complicate stretch, compressing touching stress and high

temperature, cold-hot yield stress under high speed cycling. Under these circumstance,

chemical components, mechanical properties, no-metallic inclusion, grain size, microstructure,

ultrasonic test, size precision, surface finish, all these factories of steel are required very strictly.

The Retained MPM Mandrel is the main component of rolling processing of the seamless steel pipe;

the raw material of Retained MPM Mandrel is by using AISI H13 alloy steel with very stringent

requirement on the steel rod’s purity , micro structure uniformity, impact ductility, high-temperature

performance and so on.

There are also stringent requirements on retained MPM mandrel’s roughcast with size, length, weight,

straightness, etc.
