Ngā Kaiwhakarato: Tonoa he tono kore utu mā tō kamupene hei whakahou i tō kōtaha me te tiro i tō papatohu tātaritanga ico-pere-taunoa-matau
He 99.9% te parahi parakore me ngā huānga whakarewa iti o te ngongo parahi, ā, e tutuki ana i ngā paerewa kua whakaputaina o ASTM. E wātea ana ēnei i roto i ngā momo mārō me ngā momo ngohengohe, ko te tikanga o muri ake nei kua whakamahanahia te ngongo hei whakangawari. Ka honoa ngā ngongo mārō e ngā hononga capillary. Ka taea te hono i ngā ngongo i roto i ētahi atu huarahi, tae atu ki ngā hononga kōpeketanga me ngā mura. Ka hangaia ēnei e rua hei hanganga kore hononga. Ka whakamahia ngā paipa parahi ki ngā mahi wai, HVAC, pouaka whakamātao, tuku hau hauora, pūnaha hau kōpeketanga me ngā pūnaha cryogenic. Haunga ngā paipa parahi noa, kei te wātea hoki ngā paipa whakarewa motuhake.
He āhua rerekē te kupu mō ngā paipa parahi. Ina hangaia he hua hei koiri, ka kiia i ētahi wā ko te ngongo parahi nā te mea ka tāpirihia he ngāwari me te kaha ki te piko i te rauemi. Engari ehara tēnei rerekētanga i te rerekētanga e whakamahia whānuitia ana, e whakaaetia ana rānei. Hei tāpiri, ko ētahi paipa parahi tika pakitara mārō ka kiia i ētahi wā ko ngā paipa parahi. Ka rerekē pea te whakamahinga o ēnei kupu i ia kaiwhakarato ki ia kaiwhakarato.
He rite tonu ngā ngongo katoa engari ko te rerekētanga o te matotoru o te pakitara, ko te ngongo-K te pakitara matotoru rawa, nō reira ko te teitei rawa o te pēhanga. Ko te 1/8″ te iti iho o ēnei ngongo i te diameter o waho, ā, e wātea ana i roto i ngā rahi ngongo tika mai i te 1/4″ ki te 12″, he mea kumea (mārō) me te mea whakamahana (ngāwari). Ka taea hoki te takai i ngā ngongo pakitara matotoru e rua ki te diameter 2″. Ko ngā momo e toru kua tohua e te kaihanga, he kakariki mō K, he kikorangi mō L, ā, he whero mō M.
He pai ngā momo K me L mō ngā ratonga pēhanga, pērā i te whakamahinga o ngā pūwero hau me te tuku hau māori me te LPG (K mō raro whenua, L mō roto). He pai ngā momo e toru mō te wai kāinga (Momo M te pai), te whakahaere wahie me te hinu (Momo L, te pai), ngā tono HVAC (Momo L, te pai), ngā wae korehau, me ētahi atu.
He angiangi ngā pakitara o ngā ngongo mō te waikeri, te para me te whakaputa hau, ā, he iti ake te pēhanga. Kei te wātea i roto i ngā rahi iti mai i te 1-1/4 ki te 8 inihi, ā, he kōwhai te tae. Kei te wātea i roto i ngā roa tika 20-putu te roa, engari ko ngā roa poto ake kei te wātea tonu.
Ko ngā ngongo e whakamahia ana hei whakawhiti i ngā hau hauora he momo K, he momo L rānei, me ngā whakaritenga motuhake mō te horoi. Me tango te hinu e whakamahia ana hei hanga i ngā ngongo kia kore ai e mura i te aroaro o te hāora, kia ora ai hoki te tūroro. I te nuinga o te wā ka monohia, ka taupokina hoki ngā ngongo i muri i te horoinga, ā, ka whakawerahia ki te hauota i te wā e tāuta ana.
Ko ngā ngongo e whakamahia ana mō te hauhautanga me te pouaka whakamātao ka tohua e te OD tuturu, he rerekē tēnei i roto i tēnei rōpū. Ko ngā inenga kei waenga i te 3/8 ki te 4-1/8 inihi mō ngā roa tika me te 1/8 ki te 1-5/8 inihi mō ngā koiri. I te nuinga o te wā, he teitei ake te whakatauranga pēhanga o ēnei ngongo mō te diameter kotahi.
He maha ngā momo koranu e wātea ana mō ngā tono motuhake mō ngā ngongo parahi. Ka taea e ngā ngongo parahi beryllium te tata ki te kaha o ngā ngongo koranu maitai, ā, nā tōna ātete ngenge ka tino whai hua i roto i ngā tono motuhake, pērā i ngā ngongo Bourdon. He tino ātete te koranu parahi-nikara ki te waikura o te moana, ā, he maha ngā whakamahinga o te ngongo i roto i ngā tono moana e whai hua ana te ātete ki te tipu o te pārera. Ko te Cupro Nickel 90/10, 80/20 me te 70/30 ngā ingoa noa mō tēnei rauemi. Ko ngā ngongo parahi OFHC, ko te kore-hāora rānei, he maha ngā whakamahinga mō ngā arataki ngaru me ērā atu mea. Ka taea te whakamahi i ngā ngongo parahi kua whakakikoruatia ki te Titanium i roto i ngā tono whakawhiti wera waikura.
E ai ki te kōrero i mua ake nei, he ngāwari te hono i ngā paipa parahi mā te whakamahi i ngā tikanga whakamahana pērā i te whakarewa me te whakapūmau. Ahakoa he rawaka ēnei tikanga, ā, he watea hoki mō ngā mahi pērā i te wai o te whare, ka whakamahana te ngongo kua kumea, ka whakaiti i tōna pēhanga. He maha ngā tikanga miihini e wātea ana kāore e whakarerekē i ngā āhuatanga o te ngongo. Kei roto i ēnei ko ngā hononga mura, ngā hononga awaawa hurihuri, ngā hononga kume me ngā hononga pana. He tino watea ēnei tikanga whakapiri miihini i ngā wā kāore e haumaru te whakamahi i te mura, i te whakamahana rānei. Ko tētahi atu painga ko te ngāwari o te tango i ētahi o ēnei hononga miihini.
Ko tētahi atu tikanga, e whakamahia ana i ngā wā e puta mai ai ngā manga maha i te paipa matua kotahi, ko te whakamahi i tētahi taputapu whakaputa hei waihanga i te putanga tika ki roto i te paipa. Me whakapūmau te hononga whakamutunga mō tēnei tikanga, engari kāore e hiahiatia te whakamahi i ngā hononga maha.
E whakarāpopoto ana tēnei tuhinga i ngā momo paipa parahi. Mō ētahi atu kōrero mō ētahi atu hua, tirohia ā mātou aratohu kē atu, tirohia rānei te Thomas Supplier Discovery Platform ki te kimi i ngā puna tuku pea, ki te tiro rānei i ngā taipitopito hua motuhake.
