ʻO ka pahu kinipōpō mahu

He aha nā mea maikaʻi o nā pahu pōpō puaʻa flange?

He kino i hana ʻia me ke keleawe i koho maikaʻi ʻia, SUS304, a i ʻole SUS316L, me ke kumu valve i hana ʻia me ke keleawe a i ʻole ke kila kila. Hoʻolako ʻia me kahi sila PPL kiʻekiʻe wela, loaʻa lākou i ka leakage ʻole i nā kaiapuni mahu a hiki i 250 ℃. ʻO ka pilina flange he paʻa a hilinaʻi, kū i ka hopena hammer wai, me ka haʻahaʻa haʻahaʻa a me ka pani pani ʻana a me ka hana maʻalahi. ʻO nā valves Shenchi he corrosion-resistant a me ke kaomi kiʻekiʻe, kūpono no nā pūnaewele paipu mahu, nā keʻena hoʻololi wela, a me nā kūlana hana ʻē aʻe, e hōʻemi nui ana i ka pinepine o ka mālama ʻana a me ka hoʻolilo ʻana iā lākou i nā mea hoʻomalu pani pani kūpono no nā ʻōnaehana mahu.

PPL hoʻopaʻa ʻana wela wela

Hoʻohana maʻamau ʻo Shenchi steam flange ball valves i nā sila PPL kiʻekiʻe. ʻO ka PPL (para-polystyrene) he plastik ʻenekinia kūpaʻa kiʻekiʻe me ka palena haʻahaʻa haʻahaʻa ma kahi o -20 ℃. Ma luna o kēia mahana, mālama nā sila i ka ikaika mechanical a me ke kūpaʻa dimensional. Ke hāʻule ka mahana ma lalo o -20 ℃, nalowale nā ​​​​mea PPL i kona paʻakikī, lilo i palupalu a paʻakikī, hiki ke alakaʻi i ka pau ʻole.

E pili ana i ka pale ʻana i ka wela kiʻekiʻe, hiki i ka PPL ke kūpaʻa i nā kaiapuni wela kiʻekiʻe o 260 ℃-300 ℃ no nā manawa lōʻihi, e hana maikaʻi ana ma lalo o nā kūlana mahu, me ka ʻole o ka palupalu a i ʻole ka deformation e like me PTFE maʻamau. No nā hiʻohiʻona e koi ana i nā mahana hana haʻahaʻa haʻahaʻa, hāʻawi ʻo Shenchi i kahi mana hoʻopaʻa EPDM ma ke ʻano he ʻokoʻa; Hiki i ka EPDM ke pale i nā mahana haʻahaʻa e like me -40 ℃. ʻO ka hoʻokūkū koʻikoʻi o ka valve ball flange ball valve kiʻekiʻe e pili ana i ka hoʻohālikelike pono ʻana o ka mea sila i nā kūlana hana ma ka pūnaewele.

Pili ka Media a me ka Mahana

He kūpono nā puʻupuʻu puʻupuʻu ʻo Shenchi no kahi ākea ākea, me ka wai, ka ea, ke kinoea, ka aila, nā wai like ʻole, a ʻo ka mea nui loa, ka mahu saturated. Hoʻopili ka pae wela o ka media i nā wela kiʻekiʻe, waena, maʻamau, a me ka haʻahaʻa, e loaʻa maoli ana ka uhi wela piha. E pili ana i ke koho ʻana i nā mea hoʻopaʻa paʻa: i ka wā i hoʻolako ʻia me nā sila PPL, ʻo ka pae wela e pili ana i -20 ℃ a 260 ℃, me ka mahana pōkole loa o 300 ℃, e lilo ia i mea hoʻonā maikaʻi no nā pipelines; i ka wā i hoʻolako ʻia me nā sila EPDM, ʻo ka pae wela e pili ana i -40 ℃ a 120 ℃, e ʻoi aku ka maikaʻi no nā wahi haʻahaʻa haʻahaʻa, nā ʻōnaehana wai wela, a i ʻole nā ​​kūlana mahu.

Manaʻo ʻo Shenchi i nā mea kūʻai aku e koho i nā mea hoʻopaʻa paʻa ma muli o nā mahana hana maoli. Inā ʻaʻole maopopo iā ʻoe pehea e koho ai, hiki iā ʻoe ke hāʻawi i nā ʻāpana kikoʻī, a na ka hui loea o Shenchi e ʻōlelo i ka hoʻonohonoho kūpono no ʻoe. ʻAʻole pono e hoʻoheheʻe wale ʻia ka pahu pōpō puaʻa flange kiʻekiʻe i nā wela kiʻekiʻe akā hiki ke hilinaʻi ʻia i ka wā hoʻomaka haʻahaʻa haʻahaʻa; Hoʻolālā pololei ʻia ke koho lua-sila a Shenchi no kēia kumu.
