METHOD OF STRAIGHTENING OF PIPES WITH OUTER RIBS

摘要

FIELD: process engineering.SUBSTANCE: invention relates to metal forming and can be used for making whatever pipes with outer ribs from noncorrosive steels, titanium and other alloys, to be used as structural elements for nuclear reactor active zones, etc. Rubbed pipe to be straightened is placed in jacket made of, for example, metal or PVC reinforced with synthetic thread. ID of PVC hose is 2-3 mm larger than diameter of circle circumscribed around ribbed pipe. Then, said pipe is fed to rolls of oblique roll straightener for straightening by elastic-plastic bending.EFFECT: higher-quality pipes.
