Pipeline surface pit repair tool

Abstract

The invention discloses a pipeline surface pit repair tool. The pipeline surface pit repair tool comprises a tapered lead screw and an annular tapping head; the annular tapping head is a section of cylinder with a cylindrical outer surface; a tapered threaded hole is formed in the center of the inner cavity of the cylinder in the axis of the cylinder; the cylinder is formed by a plurality of pieces opposite hooped together; the cylinder is divided into a plurality of pieces in the direction of the axis; the plurality of pieces of the cylinder are peripherally bundled up by use of an elastomer; the tapered lead screw is matched with the threaded hole of the inner cavity of the annular tapping head. The pipeline surface pit repair tool is portable, environment-friendly, easy to carry and convenient to operate. The tool is capable of repairing the pit parts of a stainless steel pipe, an aluminum pipe and a copper pipe in short time; the problems of need on oxy-acetylene flame for heating the metal pipelines, time and labor waste, difficult repair and the like are solved; in short, the pipeline surface pit repair tool has wide popularization and prospect and practical use significance.

Description

technical field [0001] The invention relates to a repair tool, in particular to a repair tool for pits on the surface of pipes. Background technique [0002] Due to improper transportation or storage, it is easy to cause pipe stacking deformation, dents, and economic losses; the full circle repair of aluminum pipes is the most common repair content in the industry, and the repair of pits is generally done by manual knocking. Use an oxyacetylene flame to heat and anneal the pit. After cooling, use a flat round hammer to extend into the tube and try to knock on the recessed part. Observe the knocking point from the outside. After adjusting and confirming the knocking point, the Hit harder until the pit is eliminated. If it is difficult to strike in the middle, it seems that the metal is hardened by hammering, and it must be heated and annealed again, and then continue after cooling. This method is generally suitable for the repair of large diameter metal pipes...

AI Technical Summary

Problems solved by technology

This method is generally suitable for the repair of large diameter metal pipes and the pits can be touched by hand. Smaller metal pipes cannot be repaired, and it has the disadvantages of burning fire, which is not conducive to pit repair.
