Description

Technical Field

[0001] The invention relates to the field of pipeline processing, in particular to a composite internal and external tapping tap for pipelines. Background Art

[0002] In modern pipeline installation and maintenance, tapping technology is widely used to process threads on the inner and outer surfaces of pipelines to achieve the connection of pipeline accessories, valves, flanges and other components. As a key tool for achieving this processing, tapping taps are usually divided into two types: internal tapping taps and external tapping taps according to the different processing objects. Internal tapping taps are used to process threads inside the pipeline, while external tapping taps are used to process threads on the outer surface of the pipeline. In the prior art, internal tapping taps and external tapping taps are usually two separate sets of tools, that is, independent tools need to be prepared for the internal and external thread processing of the pipeline respectively. Although this configuration can meet different processing requirements, each time the pipeline is processed, the operator must prepare internal tapping taps and external tapping taps separately according to the processing requirements of the pipeline. This not only increases the preparation time of the tool, but also requires frequent tool switching during the operation, which increases the work intensity and affects the processing efficiency, and the storage and management of the tool also become complicated. Especially when a large number of pipelines need to be processed, the loss, maintenance and replacement of the tool also become more cumbersome. Summary of the invention

[0003] The object of the present invention is to provide a composite internal and external tapping tap for a pipe to solve the problems raised in the above background technology.

[0005] In a further embodiment, a reinforcement ring is provided on the bottom fixing sleeve of the L-shaped connecting portion, and the reinforcement ring is coaxial with the cone head.

[0007] Preferably, the radius of the reinforcement ring is 55 mm-85 mm.
