METHOD FOR MANUFACTURING PIPES OF AUSTENITIC STEELS |
| 摘要 |
A method for manufacturing pipes of austenitic steels includes heating pre-drilled pieces, expansion thereof, heating the obtained hollow pipes, pressing, further cooling in water. Heating the billets prior to expansion is carried out to a temperature, which is determined by the formula. Heating the hollow pipes before pressing is carried to a temperature, which is by 1.017-1.034 times higher than the heating temperature of the billets prior expansion. |
