1. Womic Steel: Ngā Pūkenga Hanga me te Kaha o te Kamupene
He maha ngā raina whakaputa LSAW a Womic Steel Group mō ngā paipa ASTM A53 Grade B. Ko te A53 Grade B tētahi o ngā paerewa paipa maitai waro e tino tohua ana mō te ratonga whānui. He pai te tukanga LSAW mō ngā diameter nui kei tua atu i te whānuitanga o ngā mira ERW (ko te tikanga he ERW e herea ana ki te 24″, ki te 610mm rānei). He huarahi utu-pai ake ngā paipa LSAW a Womic hei whakakapi i ngā paipa kore hononga i ngā diameter nui.
●Raina JCOE:Mō ngā diameter 406mm – 1,422mm (16″–56″), ko te matotoru o te pakitara tae atu ki te 50.8mm.
● Raina UOE:Mō ngā diameter 508mm – 1,220mm (20″–48″), ko te matotoru o te pakitara tae atu ki te 40mm.
● Pereti Hurihuri (Tuinga Kotahi):Mō ngā diameter 600mm – 1,600mm (24″–63″), ko te matotoru o te pakitara tae atu ki te 60mm.
Neke atu i te 300,000 tāne te kaha katoa o te LSAW i ia tau, ā, neke atu i te 120,000 tāne te hanga A53 Grade B i ia tau. Kei a Womic Steel te ISO 9001, ā, ka taea e ia te tuku tirotiro tuatoru mā SGS, BV, TÜV. He rekoata ā-ao mō ngā kaupapa wai ā-tāone, ahumahi, me ngā kaupapa hanganga.
Ngāwari ki te whakaputa mō te A53 Taumata B:
● JCOE: 406–1,422mm OD × 5.0–50.8mm WT × ≤ 18m
● UOE: 508–1,220mm OD × 5.0–40.0mm WT × ≤ 24m
● Pereti hurihuri: 600–1,600mm OD × 25–60mm WT × ≤ 12m
Ka taea te tuku i ngā paipa me te paninga tuatahi (epoxy whai konutea), te whakawhanaungatanga wera-tuku, te 3LPE/FBE rānei ina tonoa.
2. ASTM A53 Tau B: Te Hanganga Rauemi me ngā Āhuatanga Mahi
Ko te ASTM A53 Grade B he kounga maitai waro mō ngā paipa whakarewa me ngā paipa tuimotu. E toru ngā momo e kapi ana: Momo F (whakarewahia te pū o te oumu), Momo E (whakarewahia te ātete hiko – ERW), me te Momo S (tuimotu). Mō ngā paipa LSAW, ka whakahuatia te Momo E, te Momo S rānei? Ko te LSAW he whakarewa pewa ruku, kāore i te kapi mārama i te A53, engari ka taea e te A53 ētahi atu tukanga whakarewa ina whakaaetia. I roto i te mahi, ka whakaaetia ngā paipa LSAW Grade B A53 mō te ratonga wai hanganga me te wai pēhanga iti i runga i ngā āhuatanga miihini.

●Ngā kōwhiringa paninga ngāwari (3LPE, FBE, galvanized, primer)
●Kei te wātea te tirotiro a te hunga tuatoru
Ngā Pātai Auau:
P: He pai te ASTM A53 Grade B mō ngā raina wai?
Āe, koinei te paerewa tino noa mō te tuku me te tohatoha wai ā-tāone. Mō te wai inu, kia tika te paninga, te arai rānei (e taunakihia ana te arai epoxy). Mō te wai mata, mō te whakamakuku rānei, e whakaaetia ana te paipa noa.
P: Ka taea te whakamahi i te paipa A53 Grade B LSAW mō te hau māori?
Āe, mō te tohatoha pēhanga iti (i raro iho i te 2 MPa te nuinga). Mō ngā pēhanga teitei ake, e taunakihia ana te API 5L GR.B, te X42 rānei. Tirohia tonu ngā waehere ā-rohe.
P: He aha te rerekētanga i waenga i te ASTM A53 Grade B me te API 5L GR.B?
A: He tata rite tonu ngā āhuatanga ā-pūkaha o ēnei (240 MPa vs 245 MPa te hua). He iti ake ngā rohe matū o te API 5L (he iti ake te P, S) ā, he pakari ake ngā whakamātautau mō ngā tono paipa raina. Mō te whakamahinga wai me te hanganga whānui, he rawaka te A53. Mō ngā paipa hinu me te hau, he pai ake te API 5L.

A: E hiahiatia ana he whakamātautau wai ātete mō ngā paipa tuimotu (Momo S) me ngā paipa ERW (Momo E) ina tohua. Mō ngā paipa LSAW i hangaia ki te A53, ka mahia te whakamātautau wai ātete mēnā e tohua ana e te ota. He maha ngā tono wai hanganga me te wai pēhanga iti kāore e whakaaetia he whakamātautau wai ātete.
Q: Ka taea e koe te whakarato i te whakapūmau wera-tuku ki te A53 Grade B?
Āe. Kei a mātou te whakapūmau werawera e ai ki te ASTM A123. Ko te roa mōrahi kotahi ko te 12.5m. Mō ngā paipa roa ake, ka tūtohu mātou kia whakapūmau wāhanga, kia pania rānei ki te paninga tuatahi.
P: He aha te roanga o te wā arahi mō te paipa A53 Grade B LSAW?
A: 20-30 ngā rā mō ngā rahi paerewa. Mō ngā diameter nui, mō ngā pakitara taumaha rānei, 35-45 ngā rā.
