  • PIPELINE ISOLATION TOOL WITH LARGE-GAP SEALING ELEMENT HAVING MINI PRESSURE HEADS AND IRIS-LIKE STRUCTURAL SEALING ELEMENTS
    Publication number: 20250369551
    Abstract: A pipeline isolation tool (10) with a circumferential seal (30) having a T-shaped cross section. The seal has a radially oriented lower seal profile (36) and an axially oriented upper seal profile (38). Pressure heads (40, 50) are located on either side (32, 34) of the lower profile. Overlapping structural elements (60, 80) are located on either side (32, 34) of the upper profile and include a concave area (70, 90) for receiving a portion of the upper seal profile. The inner face (64, 84) of the structural elements contact the outer surfaces (42, 52) of the pressure heads. Angle plates (100, 110) define an inner face (102, 112) that contacts an outer face (66, 86) of each of the structural elements. The tool may be configured as an intrusive tool or as a non-intrusive tool.
