Ngā Pātai Auau (FAQ) - Paipa Rino ASTM A572 GR.50 SSAW
P: He aha te rerekētanga i waenga i te maitai ASTM A572 GR.50 me te maitai A36?
A: Ko te kaha whakaputa iti rawa o te ASTM A572 GR.50 he 345 MPa (50,000 psi), ko te A36 he 250 MPa (36,000 psi). E 38% te kaha whakaputa teitei ake o te GR.50, e āhei ai te hanga i ngā hanganga māmā ake, me te whakaiti i te rahi o ngā wāhanga. Kua pai ake hoki te ātete o te GR.50 ki te waikura i te āhuarangi nā te hanganga HSLA.
P: Ka taea te whakarewa i te ASTM A572 GR.50 mā te whakamahi i ngā tikanga paerewa?
Āe, he tino pai te ASTM A572 GR.50 ki te whakarewa. Heoi, nā te kaha ake me te nui o te koranu (kolumiuma me te vanadium), e taunakihia ana kia whakamahia ngā tikanga whakarewa iti-hauwai. Tērā pea me whakamahana mua mō ngā wāhanga matotoru ake. Ka taea e Womic Steel te tuku tohutohu mō ngā tikanga whakarewa ina tonoa.
P: He aha te rerekētanga i waenga i te ASTM A572 GR.50 me te ASTM A992?

He rite te kaha tuku o ngā mea e rua (345-450 MPa), engari he kaha ake ngā mana whakahaere a te A992 mō ngā āhuatanga rauemi mō ngā tono rū whenua.
P: He aha te roa mōrahi mō te paipa maitai ASTM A572 GR.50 SSAW?
A: Ko ngā roa paerewa ko te 6m, 12m, me te 18m. Kei te wātea ngā roa ritenga tae atu ki te 60m i runga i te whānui me te matotoru o te pakitara. He pai ngā roa roa rawa mō ngā poupou piriti me ngā tono hanganga whānui-roa.
P: He aha ngā kōwhiringa whakaoti mata e wātea ana mō ngā tono piriti?
A: Mō ngā tono piriti, ka tukuna e mātou he paninga paninga tuatahi, he whakapūmau wera, he pūnaha ārai-waikura motuhake rānei (FBE, 3LPE, paninga epoxy rānei). Kei te wātea hoki te maitai huarere (ASTM A588) mō ngā tono piriti e hiahia ana kia ātete ki te waikura hauātea me te kore e peita.
Q: Ka taea e koe te tuku mai i ngā paipa ASTM A572 GR.50 me te tirotiro a te hunga tuatoru?
Āe. Ka whakahaerehia e mātou ngā tirotiro e SGS, BV, TÜV, DNV, ABS, LR, e tētahi atu māngai kua tohua e te kiritaki i te wā whakaputa me mua i te tuku. 3.2 ka tukuna tonutia ngā tiwhikete tirotiro ina tonoa.
