FIELD: process engineering.
SUBSTANCE: invention relates to pipe rolling. Bimetal blank comprises end ring of carbon steel and cylindrical insert of "08Х18Н10Т" grade steel. Blank shell is made of "10ГН2МФА" grade steel and shaped to 570±1.0×out 260+1.0/-0×1750±25 mm size cylinder. Said insert is made from "08Х18Н10Т" grade steel and shaped to 260+0/-1.0×80±1.01750±25 mm size cylinder. Said end ring is shaped to cylinder with OD equal to shell OD while axial bore equals or is 10 mm larger than cylindrical insert ID, insert length making 250±25 mm.
EFFECT: lower steel input, decreased amount of pipe rejects.
