Imininingwane yokukhiqiza:
Ipayipi elihlanganisiwe eliqiniswe ngocingo lwensimbi liyipayipi elisha elihlanganisiwe lepulasitiki elihlanganisiwe lensimbi elithuthukisiwe. Lolu hlobo lwepayipi lubizwa nangokuthi ipayipi le-SRTP. Lolu hlobo olusha lwepayipi lwenziwe ngamandla aphezulu ngokusebenzisa ucingo lwensimbi oluyimodeli kanye ne-thermoplastic polyethylene njengezinto zokusetshenziswa, inetha lensimbi eliqiniswe ngocingo lwepulasitiki lwe-polyethylene, i-polyethylene ephezulu (HDPE) asmatrix, esebenza kahle kakhulu ngohlaka lwe-resin oluhlanganisiwe lwe-HDPE olunesendlalelo sangaphakathi nesangaphandle se-polyethylene ephezulu eduze, Ukuze ibe nomphumela omuhle kakhulu we-compound. Ipayipi elihlanganisiwe linqoba ubuthakathaka bensimbi kanye nepulasitiki, ngenkathi ligcina izinzuzo zakho kokubili, ngoba ukuqina kwensimbi enamandla aphezulu kufakwe ku-thermoplastic eqhubekayo.
Ipayipi elihlanganisiwe eliqiniswe ngocingo lwensimbi, ukusetshenziswa kwezinto ezisezingeni eliphezulu kanye nobuchwepheshe bokukhiqiza obuthuthukisiwe, ukuze libe nokusebenza okuphezulu kokucindezela. Ngesikhathi esifanayo, ipayipi elihlanganisiwe linokuguquguquka okuhle kakhulu, elifanelekela uhlelo lwamanzi olufihliwe ibanga elide kanye nohlelo lwamapayipi egesi. Ipayipi le-polyethylene electrofuse lisetshenziselwa ipayipi elihlanganisiwe le-polyethylene eliqiniswe ngocingo lwensimbi. Uma kuxhuma, umzimba wokushisa wangaphakathi wokufakwa kwamapayipi usetshenziselwa ukuncibilikisa ipulasitiki yangaphandle yepayipi kanye nepulasitiki yangaphakathi yokufakwa kwamapayipi, ukuze ukufakwa kwamapayipi kanye nokufakwa kwamapayipi kuxhunywe ndawonye ngokuthembekile.
