Description

Technical Field

[0001] This utility model relates to the field of assembly devices, and in particular to an openable seamless pipe annular seam assembly device. Background Technology

[0002] Seamless pipe circumferential weld assembly and alignment device is a specialized instrument for precise alignment before circumferential welds on pipes, particularly crucial in high-standard pipeline welding in fields such as petrochemicals, nuclear power, shipbuilding, and pressure vessels. Its core function is to ensure a seamless connection of pipe sections' circumferential welds, providing a high-precision benchmark for subsequent welding and directly impacting weld quality and structural safety. The assembly and alignment device ensures concentricity alignment of two pipe sections, preventing stress concentration or leakage risks after welding. An adjustable clamping mechanism compensates for pipe end ovality or slight deformation. The accuracy of circumferential weld alignment directly determines the non-destructive testing pass rate of the weld. Misalignment or uneven gaps can lead to defects such as porosity and incomplete fusion. The circumferential weld assembly and alignment device, through high-precision and high-efficiency mechanical positioning, fundamentally eliminates the influence of human factors on weld quality.

However, it is inconvenient to adjust the coaxiality of the pipes during assembly. Therefore, an openable seamless pipe annular seam assembly device is provided. Utility Model Content

Several adjusting mechanisms 3 are snapped together at the outer ring sleeve 12. The adjusting mechanism 3 includes at least a connecting block 31. The connecting block 31 has an arc-shaped structure, and the side wall of the connecting block 31 extends through... A limiting groove 311 with an arc-shaped structure is opened, and the connecting block 31 is snapped onto the outer ring sleeve 12 through the limiting groove 311.
