Title: Pipe production
Inventor: GERORUTO HOORU
IPC: C21D7/12
Filed: 1996-05-14
Abstract: PROBLEM TO BE SOLVED: To correctly adjust the prescribed properties by adjusting the properties by combining the cold flaring and the cold necking and determining the order and degree of the flaring and necking according to the required sectional shape to greatly unify the strength and deformation properties in the circumferential direction of a tube. SOLUTION: In manufacture an offshore tube, a tube is first unified by the flaring, and the diameter and the compressive yield stress are adjusted by the necking. The increase of the stress is shown by the solid curve 15 starting from the origin 0. The decrease of the stress when the necking is stopped is shown by the curve 16 reaching the point A. After the load is released, the stress is dropped to the value at the point B. When the tensile test is again carried out, the stress is increased at the Y-axis value 18 below the point along the broken line 17. The Y-axis value 19 is obtained at the point F' through the reversal, i.e., by the compression test, and the Y-axis value 19 is much larger than the value obtained in the tensile test.
