ʻO ka paipu PPR Donsen, nā mea pono ppr，valve, ball valve
inoa inoa:DONSEN
Hoʻohana：Ka wai mahiai/Mariculture/Swimming pool/Engineering construction
kalakala： Nui nā kala i hiki ke koho
Mea waiwai：PPR
Mahana o Media： Kiʻekiʻe wela, haʻahaʻa haʻahaʻa, Medium Temperature, maʻamau maʻamau
Ua hanaʻia nā paipu a me nā mea pono o Donsen PPR i nā mea waiwai kiʻekiʻe i laweʻia mai, aʻo ka hanaʻana o nā huahana i hiki aʻoi aku paha ma mua o ka pahuhopu ma DIN8077 / 8088 ISO15874, Ma hope oʻekolu mau nānāʻana i nā mea maka, ma ka pūnaewele, nā huahana i hoʻopauʻia, hiki ke hōʻoia i ka maikaʻi.
Noi:hoʻohana ʻia no ka ʻōnaehana wai anuanu a wela;
Pono:maikaʻi ka wela wela, ka lōʻihi o ka lawelawe ʻana, ka pilina ikaika, nā pono waiwai

Hiki ke kala:ʻOmaomao, hina, keʻokeʻo a i ʻole noi kala ʻē aʻe
1 ʻAʻohe ʻona a me ka maʻemaʻe.
ʻO nā molekala waiwai o PP-R he mau mea kalapona a me ka hydrogen wale nō, ʻaʻohe mea ʻino a ʻona. He maʻemaʻe a hilinaʻi. ʻAʻole hoʻohana wale ia no nā paipu wai anuanu a me ka wela, akā no nā ʻōnaehana wai inu maʻemaʻe.
2 Mālama i ka wela a me ka mālama ʻana i ka ikehu.
ʻO ka conductivity thermal o ka paipu PP-R he 0.21w/mk, ʻo ia wale nō ka 1/200 o ka paipu kila.
3 ʻOi aku ka maikaʻi o ka pale ʻana i ka wela.
ʻO ka wahi palupalu o Vicat o ka paipu PP-R he 131.5 ℃. Hiki ke piʻi ka mahana hana kiʻekiʻe loa i 95 ℃, hiki ke hoʻokō i nā koi o ka ʻōnaehana wai wela i ka lako wai hale a me ke code wai.
4 Ola lōʻihi.
Ma lalo o nā kūlana o ka mahana hana o 70 ℃ a me ke kaomi hana (PN) o 1.0MPa, hiki i ke ola lawelawe o ka paipu PP-R ke piʻi aku ma mua o 50 mau makahiki (inā pono ka mea paipu he S3.2 a me S2.5 series a i ʻole. hou aku); ma lalo o ka mahana maʻamau (20 ℃) Hiki ke ola i ka lawelawe ma mua o 100 mau makahiki.
5 Hoʻokomo maʻalahi a pili pono.
He maikaʻi ka hana kuʻi ʻana o PP-R. Hiki ke hoʻopili ʻia nā paipu a me nā mea pono e ka hoʻoheheʻe wela a me ka electrofusion. He mea maʻalahi ka hoʻokomoʻana a ua hilinaʻi nā hono. ʻOi aku ka ikaika o ka hui ma mua o ka ikaika o ka paipu ponoʻī.
