Embodiment Construction
[0072] The present invention will be further described below with specific embodiment, see figure 1 —41:
[0073] Plastic pipe fittings with plastic-steel composite reinforced threaded inserts, including internal threaded sleeves 2 or external threaded sleeves 1, plastic outer coating reinforced sleeves 5 are formed outside the internal threaded sleeves 2 to form composite reinforced internal threaded inserts 3; Or a plastic inner coating reinforcing sleeve 6 is molded in the external thread sleeve 1 to form a composite reinforced external thread insert 4, and one side of the internal thread insert 3 or external thread insert 4 is injection-molded with a pipe connection part to form Plastic pipe fittings. External thread cover 1 and internal thread cover 2 are stainless steel thread cover and stainless steel external thread cover. Made of stainless steel, the chromium ions in it can just prevent the degradation and aging of polyolefin polymers, and its weather resistance and...
