DEVICE FOR PROTECTION ENDS pipes with internal coating and welded joints of pipelines against corrosion

摘要

Application: manufacture of pipes with an inner coating and the construction of pipelines by means of electric welding. Technical result: increase the quality of protection against corrosion the tube ends with the inner coating and the welded joint pipeline, and also exclusion of welding in the manufacture of pipes with an internal coating. Summary of the utility model: protection apparatus of the pipe ends with an inner coating and weld the pipeline from corrosion, consisting of a shell made of high-alloy, corrosion-resistant steel, where new is that the shell is made from high inside steel corrosion is provided with a plastic sheath through which it distribute inside the tube end. 2 ZP f ly-2 Fig.
