ASTM A53 Tau B (e mōhiotia ana hoki koASTM A 53 Tau BrāneiA53 GrB) kei te noho tonu ko tētahi o ngā whakaritenga paipa maitai waro rongonui puta noa i te ao. He whānuitia te whakamahinga i roto i te tuku wai, te hinu me te hau, ngā paipa hanganga, ngā pūnaha mīhini, me ngā paipa pūwero.
Engari ina whakaranua ngā paerewa e ngā kaupapa o te ao, ka pātai tonu ngā kaihoko:
"He aha teASTM A53he rauemi ōrite i roto i te EN, DIN, JIS rānei?”
Ka whakawhānui ake tēnei aratohu i te whakatairite, ka whakauru i ngā tohu maitai ōrite, ka whakamārama i ngā rerekētanga whakamātautau, ā, ka āwhina i a koe ki te aromatawai i te whakawhitiwhiti i te wā e rapu ana i ngā mea hou.Paipa maitai ASTM A53, paipa tui kore, ngā mea whakakapi rānei.
Te Mārama ki te ASTM A53 Taumata B: Ngā Āhuatanga Matua
Ngā uhi ASTM A53/A53Mpaipa maitai kore-tuitui (Momo S)mePaipa whakarewa ERW(Momo E)mō te kaupapa whānui.
✔ He taumata kaha waenga-teitei te ASTM A53 Grade B, e whakamahia ana i roto i te kawe wai me ngā mahi pehanga.
Awhe Matū (ASTM A53 Gr B):
Waro ≤ 0.30%
Konupora ≤ 1.20%
Whēkau ≤ 0.05%
Whānariki ≤ 0.045%
Ngā Āhuatanga Ā-ringa:
Kaha Kume ≥415 MPa
Kaha Hua ≥240 MPa
Te roanga ≥20%
Ngā Rauemi Taurite ASTM A53 GrB i roto i te EN, DIN me te JIS
He tata tonu te ōrite o ēnei tohu ki ngā rauemi ōrite ki te ASTM A53 e pā ana ki te kaha, te hanganga waro me ngā āhuatanga whakaroa.
He aha rātouHe rite tonu?
EN P235GH→ Hua: ~235 MPa, Kukū: 360–500 MPa — tata rite ki te ASTM A53 Tau B.
JIS STPG410→ He rite te taumata waro me te roa — he pai mō ngā tono e hiahia ana ki te ātete ki te pēhanga me te kaha ki te whakarewa.
Nō reira, ko te tikanga, ka taea te whakaaro ko ēnei rauemi e rite ana ki te ASTM A53 GrB, inā koa i roto i ngā paipa kōhua, hanganga me te pēhanga.
ASTM A53 vs ASTM A106 vs API 5L — He Pōhēhētanga Noa i waenganui i ngā Kaihoko
He maha ngā miihini o te ao e kore e rapu noa i"He rite ki te A53 GrB"engari me pātai anō hoki:
✔ “He rite te ASTM A106 ki te ASTM A53?”
✔ "He rite te API 5L ki te A53 GrB?"
Whakautu: kāore i te tino rite.
Nō reirale ASTM A106 Grade B meAPI 5L Karāhe B e whakahuatia pinepinetia ana, ko rātoungā kōwhiringa kē atu, ehara i te ōritetanga tino pakari.
He mea nui ngā rerekētanga hangahanga
Ahakoa he ōrite ngā rauemi ōrite o te ASTM A53 i runga i te matū, he rerekē ngā ture tirotiro:
ASTM A53 Tau B
Whakamātautau waipū
NDT mō ngā hononga whakarewa
Whakamātautau piko/whakapapatahi
E kapi ana i ngā mea e ruaERW me te kore hononga
Koia te take ka kite pinepine koe i ngā kupu mō te pūtake rauemi pēnei i te paipa maitai ASTM A53 ERW ina tohua ana ngā putanga whakarewa.
EN P235GH / P235TR
Ngā whakaritenga whakamātautau pānga tāpiri
He tuhinga anō mō te hononga whakarewa
DIN 1629
Ngā āheinga ā-ahu pakari ake mō ngā paipa tui kore
JIS G3454
He pai te mahi mō ngā tono paipa poiha me te pēhanga
Me pēhea te whakamana i te ōritetanga puta noa i ngā paerewa?
✔ Whakatauritehia ngā uara ā-pūkaha me ngā uara matū (±5% te manawanui e whakaaetia ana)
✔ Tonoa ngā tiwhikete hōputu MTC, EN/DIN/JIS rānei
✔ Arotakenga a te hunga tuatoru (pēnei i te SGS / BV / TÜV) hei whakaū i ngā paerewa whakawhiti
Ka whakaitihia e tēnei tukanga te mōrearea i te wā e whiriwhiri anaRauemi ōrite ASTM A53mō ngā kaupapa ā-ao.
