Ngomhla ziyisi-8 kuJulayi 2023, sathumela amapayipi ensimbi angenamthungo e-ASTM A335 P92 e-Italy, futhi sawaletha ngesikhathi. Kulokhu, senze ukupakishwa okuqiniswe okungu-100%, okuhlanganisa ukupakishwa kwe-PVC, ukupakishwa kwezikhwama ezilukiweyo, kanye nokupakishwa kwephepha eligcwele isipontshi, elingasetshenziswa kabusha njengoba lonke izintambo Zensimbi zisetshenziselwa ukuhlanganisa amapayipi, futhi amashubhu aseduze nawo agcwaliswa I-anti-collision bubble paper kanye nephepha lokugcwalisa isipontshi, futhi ekugcineni lipakishwe emabhokisini okhuni. Ngaphandle kwebhokisi lezinkuni, sisebenzisa futhi ibhande lensimbi eliqinile kakhulu ukulungisa ibhokisi, ukuze sivikele ngaphakathi nangaphandle kwepayipi lilonke.
Ukulethwa kwemikhiqizo evela kumakhasimende ase-Italy kuye kwabeka isisekelo esingcono semakethe yethu yaseYurophu, futhi sibheke phambili ukubambisana kwethu okulandelayo!
I-ASTM A335 P92 iyipayipi lensimbi elingenamthungo, elisetshenziswa kakhulu ezitshalweni zamandla ashisayo eminyakeni yamuva, ikakhulukazi kumapayipi amakhulu esitimu kanye nokushisisa kabusha amapayipi esitimu.
I-A335 P92 ukwakheka kwamakhemikhali: 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≤0.50 V~0.50 V~0.50 V. 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
I-ASTM A335 P92 ipayipi lensimbi engenamthungo izakhiwo: amandla aqinile ≥ 620Map, amandla esivuno ≥ 440Mpa, ubude ngemva kokuphuka ≥ 20%
I-ASEM SA335 P92 Ipayipi Lensimbi Engenamthungo Isimo Sokulethwa: Okujwayelekile + I-Tempering
ASEM A335 P92 engenamthungo ingxubevange steel ipayipi usayizi: 60.3-765 * 2-120, ububanzi evame ukusetshenziswa 60.3, 73, 88.9, 114.3, 168.3, 219.1, 273.1, 323.9, 345, 2, 2, 2, 45, 45, 45.6. I-559, 610, 660, 711, 762, namanye amasayizi nawo angenziwa ngokwezifiso ngokuya ngezidingo zamakhasimende.
Ukusetshenziswa okuyinhloko kwe-ASME SA335 P92 ingxubevange yepayipi yensimbi: isetshenziswa ikakhulukazi ekwenzeni ama-superheaters kanye nezifudumezi ezishisayo zamasethi amakhulu ejeneretha.
Ipayipi le-alloy laseMelika elijwayelekile le-ASTMA335 lihambisana nensimbi ye-P11, P12, P5, P9, P91.
I-A335 P11 iyikhodi yezinto ezibonakalayo ekhishwe yi-ASTM (American Society for Testing and Materials), futhi izinga elihambisanayo likazwelonke yi-15CrMo, i-alloy steel material.
I-ASTM A335 P5 ihambisana nensimbi ye-alloy yasekhaya: 1Cr5Mo. Isakhiwo sensimbi se-1Cr5Mo yi-martensite, enokumelana okuhle kwe-oxidation cishe ku-650 degrees Celsius, amandla amahle okushisa angaphansi kwama-degrees Celsius angu-600, ukumuncwa okuhle kokushaqeka kanye ne-thermal conductivity, futhi isetshenziswa kabanzi kuma-steam turbines.
Izinga le-American astm a335p91 lilingana nezinga likazwelonke elithi 10Cr9Mo1VNb. I-T91/P91 (10Cr9Mo1VNb)
Ukwakheka kwe-P91 (isithako wt%):
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; I-V 0,18~0,25; Nb 0.06~0.1; N 0.03~0.07; Al ≤0.04; Ni ≤0.4
Ipayipi lensimbi elijwayelekile laseMelika i-a106 ipayipi lensimbi elingenamthungo nalo lingumkhiqizo onenani elikhulu kakhulu.
Ipayipi lensimbi elingenamthungo le-ASTM A106 lingelepayipi lensimbi elijwayelekile laseMelika, i-A106 ihlanganisa i-A106-A, A106-B. Eyokuqala ilingana nempahla yasekhaya engu-10#, kanti lena yakamuva ilingana nempahla yasekhaya engu-20#.
