It is difficult to the cut repaired, influences the aesthetic appearance of pipeline.In addition, in some special industries, such as boiler tubing, have a lot
Instrument is on pipeline, and anti-corrosion or zinc-plated processing have typically all been made in the surface of pipeline, to improve its anticorrosive and inoxidizability.If
In the device of instrument and pipeline, using conventional methods, dismantled using common pipe wrench, often break and talked about surface quality,
There is surface scratch, over time, will be destroyed herein because of corrosion or oxidation, cause very big potential safety hazard.
In addition, common pipe wrench after completing to clamp, it is necessary to unclamp, if rotation is tighter or firmly excessive, when removing pipe wrench, generally
Need to tap it is several under, can just unload down, in general pipeline meter it is expensive, such percussion, be easily damaged instrument, shorten
The service life of instrument.Cause pipe connection portion position to loosen simultaneously because tapping, be also unfavorable for the sealing of pipeline.For another example in pipe
The outer surface unusual light in road, if not paying attention in installation process, the scratch for pipeline external surface occur also is easy to, both influences to manage
Road it is attractive in appearance, while also destroy the performance of pipeline to a certain extent.
An existing Chinese invention patent, it is a kind of to be exclusively used in clamping clamping without floral tube for pipeline surface, its Publication No.
CN106272200A, in pressure transmission of the no floral tube pincers on pipe wrench handle to the arc contact surface of pipe wrench and pipeline, pass through circle
The frictional force of arc contact surface rotates tubing, so as to protecting the epoxy coated layer of precoating epoxy galvanized pipe and zinc coat,
During using clamping progress Pipe installing without floral tube, the anticorrosive quality of pipeline is ensure that, pipeline anticorrosion coating need not be carried out after Pipe installing
Patch work, improve efficiency of construction, reduce construction cost, decrease maintenance of the gas pipeline run unit to pipeline
Cost.But such a pipe wrench when in use between it is long after, because jaw is smoothed, the phenomenon easily skidded, operation uneasiness
Entirely.
