METHOD OF MAKING HIGH-PRESSURE T-BENDS

摘要

FIELD: process engineering.SUBSTANCE: invention relates to machine building and may be used in production of T-bens operated at high pressure. First, forged or rolled ring-shape billet is selected to isolate central zone aggravated by defected processing strain. Said circle is divided into three zones to produce central zone and two zones shaped to "heels" at edges. Then, possibility of placing outlines of high-pressure T-bends along edges of very zone is defined. Said zones are machined to make T-bends outlined therein.EFFECT: defected processing strain zones ruled out from machining zone.2 dwg
