UNIT FOR CONNECTING PIPE-ENVELOPE MADE OF COMPOSITE MATERIAL WITH METAL BRANCH PIPE |
| 摘要 |
FIELD: reprocessing of reinforced plastic. SUBSTANCE: proposed unit is provided with ring projection. Profile of cross section of ring projection outer surface in zone between base and side of trapezoidal profile is made in form of quadratic curve. The latter is positive relative to axis of symmetry of projection curvature. Side of trapezoidal profile is in contact with flanging, being arranged at angle alpha(65°<alpha<85°) to axis of symmetry of branch pipe. EFFECT: reduced metal usage and cost. 4 cl, 5 dwg |
