Paipu Wai Wela a me Anu PPR
Ka Hoʻokaʻawale ʻana o nā Paipu Wai Wela a me Anu PPR
Aia he 54 mau huahana o PPRwela a menā paipu wai anuanu, i māhele ʻia i 11 mau kikoʻī mai dn16-dn160. Ua māhele ʻia nā huahana i 5 mau pae kaomi e like me ke kaomi: PN1.25 MPa, PN1.6 Mpa, PN2.0 Mpa, PN2.5 MPa a me PN3.2 MPa. Aia he 220 mau mea hoʻopili paipu kākoʻo, a hoʻohana ʻia nā huahana i ka lawe ʻana i ka wai piula wai home a me ka lawe ʻana i ka wai wela.
Nā hiʻohiʻona o ka paipu wai wela a me ke anu PPR:
1. Hana maʻemaʻe maikaʻi loa: ʻO ka hoʻohuihui molekala o ka mea maka PP-R he ʻelua wale nō mea: kalapona a me ka hydrogen. ʻAʻohe mea ʻino a ʻawahia. Palekana a maʻemaʻe ka huahana.
2. Kūlana maikaʻi loa: Loaʻa i ka huahana ka hana palekana hilinaʻi a hiki i ke kaomi pahū ke hiki i ka 6.0MPa. Ua hōʻoia ʻia ka maikaʻi e ka ʻoihana ʻinikua ʻo Ping An.
3. Hana hoʻokaʻawale wela maikaʻi loa: ʻO ke alakaʻi wela o ka paipu PP-R he 0.21 W/mK, ʻo ia wale nō 1/200 o kēlā o ka paipu kila. Hoʻokani pono ia i ke kuleana o ka hoʻokaʻawale ʻana o ka paipu a hōʻemi i ka nalowale o ka wela.
4. Ola lawelawe lōʻihi: Hiki i nā paipu PP-R ke loaʻa ke ola lawelawe ma mua o 50 mau makahiki ma kahi mahana hana o 70°C a me kahi kaomi hana o 1.0MPa.
5. Kākoʻo i nā paipu kūpono: Aia ma mua o 200 mau ʻano o nā paipu kūpono PP-R, nā kikoʻī: dn20-dn160, hiki ke hoʻokō i nā koi o nā ʻōnaehana lako wai hale like ʻole.
6. Palekana a maʻemaʻe hoʻi nā ʻāpana keleawe: hana ʻia lākou me ka mea keleawe 58-3, me ka nui o ke kēpau ma lalo o 3%; ua uhi ʻia ka ʻili me ka nickel, ʻaʻole ia e hoʻoulu i ka bacteria; ua knurled nā mea paʻa kaula keleawe, no laila ʻaʻole lākou e hōʻino maʻalahi i ka wā o ke kau ʻana a ʻaʻole hoʻi e hoʻohaumia.
No ke aha e koho ai i ka paipu wai wela a me ke anu GKBM PPR
Hana ʻia nā paipu wai wela a me ke anu ʻo GKBM PPR me nā lako i lawe ʻia mai Krauss Maffei lāua ʻo Battenfeld o Kelemania. Cincinnati, a me nā mea maka i lawe ʻia mai Hyosung o Kōlea Hema a me nā hale hana ʻo Basel Swiss o Kelemania. I ka wā o ke kaʻina hana nānā ʻana, nānā pono ʻia kēlā me kēia pūʻulu huahana. ʻO ka hoʻāʻo no ka maikaʻi a me ka palekana o nā huahana.
