Protective measures for secondary pollution of seamless steel pipe lining:


1. All instrument interfaces and drainage interfaces shall be opened before the pipeline assembly to prevent secondary pollution to the pipeline. Openings below 550 must be mechanically drilled, and gas welding is strictly prohibited.


2. After the installation of seamless steel pipe with plastic lining, both ends shall be blocked in time to prevent sundries from entering the installed pipes.


3. When the valve on the seamless steel pipe lining is disassembled or overhauled, sundries shall be strictly prevented from entering the pipe.
