Description

Technical Field

[0001] The utility model relates to the field of plastic pipes, in particular to a plastic-lined pipe capable of preventing plastic-steel separation. Background Art

[0002] Plastic lined pipe is a pipe with an external plastic coating or covering, usually used to transport corrosive liquids or gases. This pipe structure makes it more corrosion resistant and can provide a longer service life. Plastic lined pipe is usually supported by metal or other strong materials to ensure that it maintains its shape and structure when in use.

[0003] In the existing technology, although a certain pipeline connection can be achieved during use, there is a defect: the existing plastic-lined pipe lacks a stable connection state, which leads to the problem of easy separation when connecting the steel plate, affecting the overall connection effect. In view of this, we propose a plastic-lined pipe that prevents plastic-steel separation to solve the above problem. Utility Model Content
