hoe mokowā kau A515 gr 60 ahua 8 matapo mōhiti
Ko te Paddle Blank Spacer i roto i te ASTM A515 Grade 60, i whirihorahia hei Figure-8 Spectacle Blind Flange, he taputapu haumaru me te wehe nui i roto i ngā pūnaha paipa ahumahi. He mea auaha te whakakotahi i ngā mahi e toru ki roto i te kotahi waeine pakari: he pereti matapo totoka mō te wehe pai, he mowhiti wehe mō te rere-mā roto, me te tukutuku hono me te kakau "hoe" roa hei tautuhi tirohanga mārama.
He mea hanga, he mea hanga rānei mai i te maitai waro kounga ASTM A515 Grade 60 o te oko pēhanga, he tino kaha, he roa hoki te mau o tēnei wāhanga mō te mahi pāmahana waenga ki te pāmahana teitei. Mā te hoahoa "ahua-8" ka taea e ngā kaiwhakahaere te whakatau tere i te tūnga o te raina (tuwhera, wehe rānei) mai i tawhiti, he āhuatanga nui mō ngā tikanga raka/tāko (LOTO) me te haumaru o te tipu. I hangaia kia rite ki ngā paerewa ASME B16.48, ka whakarite i te mahi pono hei raina kore, ka whakarato i te hiri tino, ā-piri ina herea te pito totoka ki waenga i ngā flanges. Nā tōna hanganga pakari ka waiho hei taputapu tino nui mō te tiaki haumaru, te whakamātautau pūnaha, me ngā huringa whirihoranga tukanga i roto i ngā taiao uaua.

NGĀ PAEREWA WHĀNUI
Whakaaturanga Taipitopito o ngā Hua
Rauemi me te Hanganga:
He mea tapahi tika te arai mōhiti mai i te maitai pereti ASTM A515 Grade 60, he rauemi kua tohua mō ngā tono ipu pēhanga pāmahana waenga me te teitei. He iti rawa te kaha kume o te 415 MPa (60 ksi) me te pai o te whakarewa. Mō te mahi nui, ka taea te whakarato i te A516 Grade 60, 70 rānei.
Mīhini Tika:
Ka mīhinihia ngā mata katoa, inā koa ngā mata hiri e pā ana ki te gasket, kia maeneene te āhua (ko te tikanga he 125-250 AARH te āhua mō te RF). Ka pokaia ngā kōhao pūtu, ā, ka hurihia kia rite ki ngā whakaritenga ASME B16.5, kia tino tika ai te tūnga ki ngā flanges e hono ana, kia ārai hoki i te ahotea pūtu i te wā tāutanga.
Ngā Āhuatanga Hoahoa:
Ko te "hoe" o waenganui he wāhanga nui o te whakaaturanga, e whakarato ana i te kakau pakari mō te hurihuri me te tohu tirohanga mārama. He maha ngā wā ka peitahia ki ngā tae kitea nuitia (hei tauira, he kōwhai mō te taha whakawātea, he whero mō te taha matapo) e ai ki ngā paerewa tipu. Ka tatauhia te matotoru o ngā wāhanga matapo me te whakawātea kia tu atu ki te pēhanga paipa katoa, kia pai ai te pēhi i te gasket me te kore e piko.
Mahi:
Ka huri te waeine i runga i ngā pūtu i waenganui i ngā parirau paipa e rua. I te tūranga "tuwhera", ka hāngai te mowhiti whakawātea ki te pū o te paipa, kia rere ai te wai. I te tūranga "kati" me te "matapo" rānei, ka ārai katoa te pereti totoka i te aho, ka whakarato i tētahi pūwāhi wehe pai ake i te takirere kati.
Te Tohu:
He mea tā mooni tonu e ai ki ngā whakaritenga a te ASME B16.48, tae atu ki te karaehe rauemi (A515 Gr.60), te rahi, te akomanga pēhanga, me te tohu a te kaihanga.
TE TOHU ME TE TAKAI
Takai: Ka tiakina takitahi ia arai mōhiti. Ka pania ngā mata hiri kua oti te hanga ki te ārai waikura, ā, ka hipokina ki te kirihou, ki te kātene rānei. Kātahi ka takaihia te wae ki te pepa VCI (Aukati Waikura Kohu) hei ārai i te waikura i te wā e kawe ana. Mō ngā rahi nui ake, ka whakamahia ngā pouaka rakau ritenga me ngā tautoko ā-roto. Ka taea te whakatakoto i ngā rahi iti ki runga i te papa me te tiaki taha.
Tohu: Kua tāpirihia he tohu ātete-huarere, e whakaatu ana i te tau wāhanga, te rahi, te akomanga pēhanga, te rauemi, me te ūnga. Kua tohua mārama te pouaka, te paihere rānei ki ngā tohu whakahaere (hei tauira, "Tēnei taha ki runga," "Kia maroke").
Tukunga: Ka whakamahia e mātou ngā tikanga tuku tino pai i runga i te rahi me te tere o te ota—mai i ngā ipu moana paerewa mō ngā ota nui ki ngā uta rererangi mō ngā kaupapa tere. Ka whakaritea marietia ngā tuhinga tuku katoa e tika ana (rārangi tākai, nama arumoni, tiwhikete takenga mai) kia pai ai te tuku i ngā taonga puta noa i te ao.
TE TIROTIRO
Ka whiwhi ia pereti maitai ASTM A515 Grade 60 i te tiwhikete rauemi whānui. Ka whakahaerehia e mātou he tātaritanga matū hei manatoko kei te tutuki te hanganga matū i ngā whakaritenga taumata, tae atu ki te waro, te konupūmā, te whākōkī, te whanariki, me te ihirangi silicon. Kei roto i ngā whakamātautau āhuatanga miihini ko te kaha kume (iti rawa 415 MPa), te kaha hua (iti rawa 205 MPa), me ngā inenga roa e ai ki ngā paerewa ASTM A370. Mō ngā tono pāmahana iti, ka taea te mahi i te whakamātautau pānga Charpy V-Notch kōwhiringa i ngā pāmahana kua tohua (paerewa iti rawa -29°C) hei manatoko i te pakari o te rauemi.
Ka whakamanahia ia parepare matapo mōhiti 100% te āhua mā te whakamahi i ngā taputapu ine kua whakatikatikaina. Ko ngā āhua matua e tirohia ana ko: te whānui o waho (±1.5mm te manawanui), te whānui o te porowhita pūtu (±0.8mm), te whānui me te tūranga o te kōhao pūtu (±0.5mm), te matotoru (±0.5mm e ai ki ngā whakaritenga ASME B16.48), me te papatahi kanohi ki te kanohi (i roto i te 0.2mm puta noa i ngā mata hiri). Ka aro nui ki te whakaritenga o te kakau hoe me te whakamana i te ātea mō te huri tika i waenga i ngā parepare paerewa ASME B16.5.
