What are the connection methods of plastic coated steel pipes

Date: 2020-04-17

What are the connection methods of plastic coated steel pipes? What are the connection methods of plastic coated steel pipes? 1. Threaded connection The automatic threading machine shall be adopted for the threading, and the current national standards shall be implemented. 2. Flange connection One-time installation method: it can measure and draw the single-line processing drawing of the pipeline on the spot, process the coating and plastic lining, and then arrive at the site for installation. Secondary installation method: Non-coated, plastic-lined steel pipes and fittings can be used on site, flanges are welded, pipes are assembled, then disassembled for coating and plastic-lined processing, and then shipped to the site for installation. 3. Groove connection Finished grooved plastic-coated fittings should be used first; grooves should be grooved with special roll groovers, and the groove depth should comply with relevant standards.
