I te 8 o Hūrae, 2023, i tukuna e mātou ngā paipa maitai koranu kore hononga ASTM A335 P92 ki Itari, ā, i tukuna atu i te wā tika. I tēnei wā, i hangaia e mātou he takai whakapakari 100%, tae atu ki te takai PVC, te takai putea whatu, me te takai pepa kī tonu i te hautai, ka taea te whakamahi anō. Ka whakamahia ngā whitiki maitai hei here i ngā paipa, ā, ka whakakīia ngā ngongo i te taha ki te pepa mirumiru ārai-tukituki me te pepa whakakī hautai, ā, ka tākaihia ki roto i ngā pouaka rakau. I waho o te pouaka rakau, ka whakamahia hoki e mātou he whitiki maitai tino kaha hei whakau i te pouaka, kia tiakina ai te roto me waho o te paipa katoa.
Nā te tukunga mai o ngā hua mai i ngā kiritaki Itari kua whakatakoto i tētahi turanga pai ake mō tō mātou mākete Pākehā, ā, e tino tumanako ana mātou ki tā mātou mahi tahi e whai ake nei!
He paipa maitai kore-tuukore te ASTM A335 P92, e whakamahia nuitia ana i ngā tipu hiko wera i ngā tau tata nei, ko te nuinga mō ngā paipa mamaoa matua me te whakamahana anō i ngā paipa mamaoa.
Hanganga matū A335 P92: C: 0.07~0.13 Si: ≤0.50 Mn: 0.30~0.60 P≤0.020 S≤0.010 Cr: 8.50~9.50 Mo: 0.30~0.60Ni≤0.40 V:0.15~0.25 N:0.03~0.07 Al: ≤0.02 Ti: ≤0.01 Zr≤0.01Nb: 0.04~0.09 W: 1.5~2.0 B: 0.001~0.006
Ngā āhuatanga hangarau o te paipa maitai koranu korekore ASTM A335 P92: kaha kume ≥ 620Map, kaha hua ≥ 440Mpa, elongation i muri i te whati ≥ 20%
Tūnga Tukunga Paipa Rino Koranu Korekore ASEM SA335 P92: Te Whakaōrite + Te Whakamātao
Ko te rahi o te paipa maitai ASEM A335 P92 he mea hanga ki te koranu kore hononga: 60.3-765*2-120, ko ngā diameter e whakamahia whānuitia ana ko te 60.3, 73, 88.9, 114.3, 168.3, 219.1, 273.1, 323.9, 355.6, 406.4, 457.2, 508, 559, 610, 660, 711, 762, me ētahi atu rahi ka taea te whakarite kia rite ki ngā hiahia o te kiritaki.
Te tono matua o te paipa maitai koranu ASME SA335 P92: te nuinga e whakamahia ana i roto i te hanga o ngā whakamahana nui me ngā whakamahana anō mō ngā huinga whakaputa nui.
Ko te paipa koranu paerewa ASTMA335 o Amerika e rite ana ki te rauemi maitai P11, P12, P5, P9, P91.
Ko te A335 P11 he waehere rauemi i whakaputaina e ASTM (American Society for Testing and Materials), ā, ko te paerewa ā-motu e rite ana ko te 15CrMo, he rauemi maitai koranu.
Ko te ASTM A335 P5 e rite ana ki te maitai koranu o te whare: 1Cr5Mo. Ko te hanganga whakarewa o te 1Cr5Mo he martensite, he ātete pai ki te waikura i te 650 nekehanga Celsius, he kaha wera pai i raro i te 600 nekehanga Celsius, he pai te mimiti ru me te kawe wera, ā, he whānuitia te whakamahinga i roto i ngā tāhūhū mamaoa.
Ko te paerewa Amerikana astm a335p91 he rite ki te paerewa ā-motu 10Cr9Mo1VNb. T91/P91 (10Cr9Mo1VNb)
Te hanganga rauemi o te P91 (te taumaha o te kai%):
C 0.08~0.12; Mn 0.30~0.60; Si 0.20~0.50; P ≤0.02; S ≤0.01; Cr 8.0~9.5;
Mo 0.85~1.05; V 0.18~0.25; Nb 0.06~0.1; N 0.03~0.07; Al ≤0.04; Ni ≤0.4
He nui rawa te hua o te paipa maitai tui kore o te paerewa Amerikana, arā, ko te paipa maitai tui kore o te A106.
No te paerewa o Amerika te paipa maitai korekore ASTM A106, kei roto i te A106 te A106-A me te A106-B. Ko te mea tuatahi he rite ki te rauemi 10# o te kāinga, ā, ko te mea tuarua he rite ki te rauemi 20# o te kāinga.
