Ua kapa ʻia ʻo PE insulation pipe he PE outer protection pipe, jacket pipe, sleeve pipe. Hana ʻia ka paipu insulation polyurethane i kanu ʻia me ka paipu insulation HDPE ma ke ʻano he pale pale o waho, hoʻohana ʻia ka polyurethane rigid foam i hoʻopiha ʻia ma ke ʻano he mea hoʻoheheʻe, a ʻo ka ʻaoʻao o loko he paipu kila. Polyure-thane pololei kanu insulation paipu i maikai mechanical waiwai a me ka thermal insulation hana. Ma lalo o nā kūlana maʻamau, hiki iā ia ke kū i ke kiʻekiʻe kiʻekiʻe o 120-180 ° C, a he kūpono ia no nā ʻano wai anuanu a me ka wai wela kiʻekiʻe a me ka haʻahaʻa haʻahaʻa o ka pipeline insulation projects.
