ʻO ka paipu PE (pipa HDPE) i hana ʻia me ka polyethylene ma ke ʻano he kumu kumu, hoʻohui i nā antioxidants, kalapona ʻeleʻele a me nā mea kala.Hōʻike ʻia ia e ka haʻahaʻa haʻahaʻa, ka ikaika kikoʻī kiʻekiʻe, ke kūpaʻa haʻahaʻa haʻahaʻa maikaʻi a me ka paʻakikī, a hiki i ka embrittlement wela ke hiki i -80 °C.
Hiki ke hana ʻia a hana ʻia ka plastic pipe PE e nā ʻano hana like ʻole e hana i nā huahana like ʻole e like me nā kiʻiʻoniʻoni, pepa, paipu, profiles, etc.;a he mea maʻalahi no ka ʻokiʻoki, hoʻopaʻa ʻana a me ka hana "weld".He maʻalahi ke kala a hiki ke hana ʻia i nā kala ʻālohilohi;hiki ke hana ʻia ma ka paʻi ʻana, electroplating, paʻi ʻana a me ka embossing, hana i nā plastics waiwai i nā hopena hoʻonaninani.
ʻO ka hapa nui o nā plastics i ʻoi aku ka ikaika o ka corrosion resistance i ka waika, alkali, paʻakai, a me nā mea ʻē aʻe ma mua o nā mea metala a me kekahi mau mea inorganic, a kūpono loa i nā puka a me nā puka makani, nā papahele, nā paia, a me nā mea kanu kemika;Hiki ke hoʻoheheʻe ʻia nā thermoplastics e kekahi mau mea hoʻoheheʻe organik, ʻoiai ʻo nā plastik thermosetting ʻAʻole hiki ke hoʻoheheʻe ʻia, hiki ke hoʻohū wale kekahi.Hiki ke hoʻohana nui ʻia nā plastics i ka wai kūlohelohe i ka wai kaiapuni, ka haʻahaʻa haʻahaʻa o ka wai, a hiki ke hoʻohana nui ʻia i nā papahana wai a me ka moisture-proof.
ʻAʻole kiʻekiʻe ka pale wela o nā paipu paipu PE.Ke hoʻokau ʻia i nā haʻawe i nā wela kiʻekiʻe, ʻano palupalu a hoʻoheheʻe ʻia, a i ʻole decompose a deteriorate.ʻO ka wela wela o nā thermoplastics maʻamau he 60-120 °C, a he mau ʻano liʻiliʻi wale nō ke hoʻohana ʻia no ka manawa lōʻihi ma kahi o 200 °C..He maʻalahi ke puhi ʻana i ke ahi a i ʻole ke ʻā mālie ʻana o kekahi mau palaka, a e hoʻopuka ʻia ka nui o nā uahi ʻawaʻawa i ka wā e ʻā ana, e make ai ke ahi i nā hale.ʻOi aku ka nui o ka coefficient o ka hoʻonui laina o ka plastic, ʻo ia ka 3-10 mau manawa nui ma mua o ka metala.No laila, nui ka deformation o ka mahana, a ua maʻalahi ka mea i hōʻino ʻia ma muli o ka hōʻiliʻili ʻana o ke kaumaha wela.
Ma muli o kāna hana haʻahaʻa haʻahaʻa haʻahaʻa maikaʻi loa a me ka paʻakikī, hiki iā ia ke pale i ka pōʻino o ke kaʻa a me ka haʻalulu mechanical, ka hana freeze-thaw a me ka hoʻololi koke ʻana i ke kaomi hana.No laila, hiki ke hoʻohana ʻia nā paipu wili no ka hoʻokomo ʻana a i ʻole ka palau ʻana i ka hana, kahi kūpono no ke kūkulu ʻana a haʻahaʻa i ke kumukūʻai ʻenehana;ʻO ka pā paipu maʻemaʻe, liʻiliʻi ke kū'ē o ke kahe ʻana, haʻahaʻa ka hoʻohana ʻana i ka ikehu o ka mea lawe, a ʻaʻole i hoʻopili ʻia e nā hydrocarbons wai i ka mea lawe.ʻO nā paipu PE medium a me ke kiʻekiʻe kiʻekiʻe he kūpono no ke kinoea kūloko a me nā pipeline kinoea kūlohelohe.ʻO nā paipu PE haʻahaʻa haʻahaʻa kūpono no ka inu ʻana i nā paipu wai, nā kaula kelepona, nā paipu hoʻoheheʻe ʻana i ka mahiʻai, nā paipu hale hoʻoheheʻe, a me nā mea ʻē aʻe.
