Te Mahi a te Kakau o te Takirere Pūrerehua Hiri Ngāwari GGG40

Ki te whakatauritea ki ngā takirere pūrerehua wafer, he kaha ake te pumau o ngā takirere pūrerehua lug, he iti ake te pānga o te whakarara o te flange pipeline me te koretake o te kume o te pūtu, ā, he nui ake te pono o te hiri; ki te whakatauritea ki ngā takirere pūrerehua flange, ka poto ake te roa tuaka mā te 30% ~ 50%, ka kiato ake te rōrahi, ka whakaitihia te taumaha mā te 20% ~ 40%, ā, ka penapenahia te wāhi tāutanga me ngā utu kawe.

1. He tino whai hua te tāutanga me te tiaki: Mā te hononga taringa e pū ake ana ka taea te wetewete motuhake i ngā takirere me te kore e hiahiatia te wetewete i ngā paipa o runga me raro. I te wā tiaki, kāore e pā ki te mahi o te pūnaha paipa katoa, ka whakaitihia te wā kore mahi; He iti te rahi ki te whakataurite ki ngā takirere pūrerehua flange, he pai mō ngā āhuatanga he paipa kikī me ngā wāhi tāutanga whaiti.

2. Hononga pumau me te hiri pono: Ka herea tika ngā taringa e pupū ake ana ki te flange paipa, kia ōrite ai te tohatoha o te kaha, kia kore ai hoki e rahua te hiri i puta mai i te kaha piri koretake i roto i te takirere pūrerehua; He hoahoa hiri rua-ahu, kāore he here i runga i ngā ahunga kawemai me te kaweake, he pai mō ngā pūnaha paipa me te rere rua-ahu o ngā pāpāho.

3. He kaha teitei, he whānui hoki te urutau: Ko te hanganga taringa e kokiri ana o te tinana takirere e whakarei ake ana i te pakari whānui, ā, ka taea te tu atu ki te pēhanga paipa teitei me te rerekētanga pēhanga waenga. Ko te whakatauranga pēhanga tuku iho e kapi ana i te PN1.0~PN6.4MPa (ka taea e ētahi tauira pēhanga teitei te eke ki te PN10.0MPa), ā, ko te diameter e kapi ana i te DN50~DN2000, e tika ana mō ngā āhuatanga mahi pēhanga waenga iti ki te pēhanga waenga teitei, waenga iti ki te diameter nui.

4. Ngā momo taraiwa ngāwari me te kanorau: ka taea te whakataurite ki ngā kakau (te rahi iti, te pēhanga reo iti), ngā tāpine (te rahi nui, te rerekētanga pēhanga teitei, me te mahi raka-ake), te hau (te whakatuwheratanga me te kati tere, kua urutau ki ngā pūnaha aunoa), te hiko (te mana mamao, te mana tika) me ētahi atu momo taraiwa hei whakatutuki i ngā hiahia o ngā āhuatanga rerekē pēnei i te mahi ā-ringa, te whakahaere aunoa, me te mahi kore tangata.

5. Te whai huatanga taurite o te utu: Ki te whakatauritea ki ngā takirere pūrerehua flange, he iti ake ngā utu hanga me te tāutanga; ki te whakatauritea ki ngā takirere pūrerehua, he teitei ake te pono o te hiri me te kaha o te hanganga, ka waiho hei whakataurite i waenga i te "ōhanga" me te "pono".

Tākai pouaka rakau kaweake paerewa

He pai te takirere pūrerehua mō ngā paipa hinu, matū, kai, rongoā, hanga pepa, hiko wai, kaipuke, tuku wai me te rerenga wai, whakarewa, pūngao me ētahi atu pūnaha. Ka taea te whakamahi hei taputapu whakahaere me te kati i ngā paipa me ngā ipu paura me ngā ipu waikura, kore waikura, wai, wai haurua, me te paura totoka.
