HPT-55’s equipment and pipes manufacturing process.
Justification of rational technology and facilities in process of product manufacturing.
Calculating the calibration of HPT-55’s working tool.
Calculation of strength and elastic deformation of stand’s parts.

☓ 2 mm sized pipe from the core range was chosen for the research.
It is manufactured out of steel 12X18H10T in accordance with GOST 5632-72.

Calculation of rolling route

Output data:
dimensions of workpiece:
DЗ ☓ SЗ = 57 ☓ 4 mm
dimensions of finished pipe:
DT ☓ ST = 25 ☓ 2 mm
steel grade: 12Х18Н10Т
