MukamagulaChitoliro chachitsulo chopanda msoko cha ASTM A335Pa mafakitale opangira magetsi, mafakitale oyeretsera kapena mapaipi otentha kwambiri, ogula nthawi zambiri amakumana ndi mitundu yosiyanasiyana ya zinthu zomwe zimafotokozedwa m'mafotokozedwe aku America, China, Europe ndi Russia.
Pulojekiti ikhoza kufotokozaASTM A335 P11kapena P22, pomwe wogulitsa wakomweko angatchule mtengo15CrMo, 15ХМ, 10CrMo5-5 kapena 10Х2МPoyamba, mitundu iyi ingawoneke ngati yosinthika chifukwa ndi ya mabanja ofanana a chromium-molybdenum alloy steel.
Komabe,kapangidwe ka mankhwala kofanana sikutanthauza kuti zofunikira zaukadaulo zofanana zokha.
Pa kugula zinthu padziko lonse lapansi, funso lofunika si lakuti “Kodi ndi giredi iti yomwe ili yofanana?” koma ngati zinthu zomwe zaperekedwa zikukwaniritsa zomwe polojekitiyi yapereka.muyezo, kapangidwe ka mankhwala, mawonekedwe a makina, chithandizo cha kutentha, mayeso ndi zofunikira pa kapangidwe.
Kodi ASTM A335 ndi chiyani?
ASTM A335/A335Mndiye tsatanetsatane wachitoliro chachitsulo cha ferritic chopanda msoko chogwiritsidwa ntchito kutentha kwambiriMndandanda wa ASTM womwe ulipo pano ukuwonetsa kuti A335/A335M-26 ndi mtundu womwe ukugwira ntchito. Mafotokozedwewa akukhudza mitundu ingapo ya ferritic alloy-steel, kuphatikizaP11 ndi P22, ndipo ikuphatikizapo zofunikira zokhudzana ndi kapangidwe ka mankhwala, mawonekedwe a makina, kuuma, kuyesa kwa hydrostatic ndi kuyesa kosawononga.
Kusankha pakati pa P11, P22 ndi magiredi ena kumadalira momwe ntchito ikuyendera komanso zofunikira pa polojekitiyi osati dzina la giredi lokha.
Kwa ogula, awiri mwa magulu omwe amakambidwa kwambiri ndi awa:
●ASTM A335 P11 — pafupifupi 1.25Cr-0.5Mo dongosolo la aloyi
●ASTM A335 P22 — pafupifupi 2.25Cr-1Mo alloy system
Kuchuluka kwa chromium ndi molybdenum mu P22 kumaipatsa mawonekedwe osiyana a kutentha kwambiri ndi P11. Zofunikira za mankhwala za ASTM zimalemba pafupifupi 1.00–1.50% Cr ndi 0.44–0.65% Mo ya P11, ndipo pafupifupi 1.90–2.60% Cr ndi 0.87–1.13% Mo ya P22.
ASTM A335 P11 vs 15CrMo / 15ХМ
ASTM A335 P11imagwiritsidwa ntchito kwambiri popangira mapaipi otentha kwambiri ndi zida zina zotenthetsera.
Mu matebulo oyerekeza zinthu padziko lonse lapansi, P11 nthawi zambiri imagwirizanitsidwa ndi1.25Cr-0.5Mobanja, kuphatikizapo10CrMo5-5ndi Chitchaina15CrMozofotokozera. Ogulitsa ena ndi misika amagwiritsanso ntchito zofotokozera za ku Russia monga15ХМ, koma giredi yeniyeni ya ku Russia ndi muyezo wazinthu ziyenera kutsimikiziridwa nthawi zonse motsutsana ndi zomwe zafotokozedwa mu polojekitiyi.
Mfundo yothandiza kwa ogula ndi yakuti dzinalo lingasinthe kuchokera pamsika wina kupita ku wina pomwe banja la alloy lomwe lili pansi pake likhoza kukhala lofanana.
| Kusankhidwa kwa zinthu | Banja lazinthu wamba | Nkhani yogula zinthu yodziwika bwino |

Tebulo liyenera kugwiritsidwa ntchito ngatipoyambira kuyerekeza, osati ngati tebulo losinthira lokhaKusankha komaliza kwa zinthu kuyenera kutsatira muyezo woyenera komanso ndondomeko ya polojekitiyi.
Mwachitsanzo, wogula akuyitanitsaChitoliro chopanda msoko cha ASTM A335 P11sayenera kungosintha ndi 15CrMo chifukwa mankhwala omwe ali m'mafakitale amawoneka pafupi. Woperekayo ayenera kutsimikizira zofunikira zonse, kuphatikizapo mawonekedwe a chinthucho, kutentha, mawonekedwe a makina, mayeso ndi zolemba.
P22 vs 10CrMo5-5 / 10Х2М: Chifukwa Chake Kuyerekeza Kumafunika Kusamalidwa
Kuyerekeza kwachiwiri kumafuna chisamaliro chowonjezereka.
ASTM A335 P22ndi ya pafupifupi2.25Cr-1Mobanja. Mabuku a ku Ulaya omwe nthawi zambiri amagwirizanitsidwa ndi banjali ndi awa:10CrMo9-10 / 10CrMo910, pamene10Х2Мimapezekanso mu zokambirana za Chirasha/CIS.
Mosiyana ndi zimenezi,10CrMo5-5 nthawi zambiri imagwirizanitsidwa ndi banja la 1.25Cr-0.5Mo lower-alloy ndipo nthawi zambiri imagwirizanitsidwa ndi A335 P11., osati P22.
Kusiyana kumeneku n'kofunika kwambiri pamene dipatimenti yogula zinthu imalandira makoteshoni ochokera kumayiko osiyanasiyana.
Lingaliro losavuta la zinthu zakuthupi ndi banja ndi ili:
| Giredi ya ASTM | Banja la aloyi loyerekeza | Maumboni odziwika padziko lonse lapansi |
| A335 P11 | 1.25Cr-0.5Mo | 15CrMo/ Banja la 10CrMo5-5 |
| A335 P22 | 2.25Cr-1Mo | 10CrMo9-10 / 10CrMo910 / ma referensi osankhidwa a 10Х2М |
Chifukwa chake, ngati kufotokozera kwa polojekiti kukufunikaASTM A335 P22, mtengo wa 10CrMo5-5 uyenera kuperekedwaosatikuvomerezedwa ngati chofanana mwachindunji popanda kuwunikanso ukadaulo.
Apa ndi pomwe akatswiri odziwa bwino ntchito zopezera zinthu padziko lonse lapansi amafunikira:nambala ya zinthu, muyezo wa chinthu ndi momwe polojekiti igwiritsidwira ntchito ziyenera kuganiziridwa pamodzi.
N’chifukwa Chiyani Ogula Amayerekeza Magiredi Awa?
Chifukwa chake n'chosavuta: mapulojekiti apadziko lonse nthawi zambiri amakhala ndi miyezo ingapo nthawi imodzi.
Malo opangira magetsi angagwiritse ntchito:
●ASTM A335 P11/P22 ya mapaipi otentha kwambiri
●ASTM A213 T11/T22 ya machubu a boiler ndi heat-exchange
●Mbale yachitsulo ya ASTM A387 Cr-Mo ya ziwiya zopanikizika
●Machubu achitsulo a EN 10216-2
●Magiredi a GB/T a zida zopezeka m'deralo
●Zipangizo zodziwika bwino za GOST kapena Russian za mapulojekiti a CIS
Kwa kontrakitala wa EPC, kusintha chinthu chimodzi ndi china kungakhudze:
Kapangidwe → Kuwotcherera → Kutentha → Kuyang'anira → Zolemba → Kuvomereza
Chifukwa chake, kuyerekeza magiredi kuyenera kuchitika musanagule, osati zinthuzo zitayitanidwa kale.
P11 kapena P22: Ndi Giredi iti yomwe Ogula Ayenera Kutchula?
Yankho lake limadalira momwe zinthu zilili pa ntchito yeniyeni.
P11Kawirikawiri amaganiziridwa pamene polojekitiyi ikufuna chitsulo cha Cr-Mo chotsika chomwe chingagwiritsidwe ntchito kutentha kwambiri.
P22imapereka mulingo wapamwamba wa Cr-Mo alloy ndipo imagwiritsidwa ntchito m'mapulogalamu pomwe kufotokozera kwa polojekitiyi kumafuna zinthu zomwe zikugwirizana ndi momwe kutentha kumagwirira ntchito.
Madera omwe amagwiritsidwa ntchito nthawi zambiri ndi awa:
| Kugwiritsa ntchito | Zitsanzo zakuthupi |
| Makina otenthetsera ndi nthunzi yothandizira | Magiredi a P11 / ofanana ndi a Cr-Mo |
| Mapaipi a nthunzi otentha kwambiri | P11 / P22 kutengera kapangidwe kake |
| Mitu ya fakitale yamagetsi | P11 / P22 / magiredi ena otchulidwa |
| Mapaipi opangira makina oyeretsera | P11 / P22 kutengera ndi ntchito |
| Mapaipi otentha kwambiri a Petrochemical | P22 ndi magiredi ena a Cr-Mo |
| Zipangizo zopanikizira | Zinthu za Cr-Mo zokhudzana ndi polojekitiyi |
Giredi yoyenera iyenera kusankhidwa kuchokera kukutentha kwa kapangidwe, kupanikizika, kupsinjika kovomerezeka, malo ogwirira ntchito ndi code yogwiritsira ntchito kapangidwe, m'malo moyerekeza mitengo ya zinthu zokha.
ASTM A335 P11 ndi P22 Sizofanana ndi ASTM A213 T11 ndi T22
Vuto lina lofala kwambiri pakugula zinthu ndi losokonezamagiredi a mapaipindimagiredi a chubu.
Mwachitsanzo:
●ASTM A335 P11 → chitoliro chopanda msoko cha alloy-chitsulo chogwiritsidwa ntchito kutentha kwambiri
●ASTM A213 T11 → boiler yopanda msoko, superheater ndi chubu chosinthira kutentha
●ASTM A335 P22 → chitoliro chopanda msoko cha alloy-chitsulo
●ASTM A213 T22 → chubu chopangidwa ndi ntchito zomwe zaphimbidwa ndi A213
Maina a P11/T11 ndi P22/T22 ndi ofanana mkati mwa banja la Cr-Mo alloy, koma miyezo ya malonda ndi yosiyana.
Kusiyana kumeneku n'kofunika pokonzekera oda yogulira, chifukwagiredi + muyezo wa chinthu + miyeso + zofunikira pakuyesazonse ziyenera kugwirizana ndi zomwe zafotokozedwa mu polojekitiyi.
Kodi Ogula Ayenera Kuyang'ana Chiyani Asanayitanitse?
MukamagulaChitoliro cha ASTM A335 P11 or Chitoliro cha ASTM A335 P22, funso lalifupi monga lakuti “chitoliro cha P11, chonde tchulani” silingakhale lokwanira.
Kuti mtengo ukhale wolondola, ogula ayenera kupereka:
1. Muyezo wazinthu — ASTM A335/A335M
2. Giredi — P11, P22, ndi zina zotero.
3. Kukula kwa chitoliro — NPS kapena OD × makulidwe a khoma

Kodi SANONPIPE Ingathandize Bwanji Pakugwiritsa Ntchito Zinthu Zosiyanasiyana?
Kwa makasitomala apadziko lonse lapansi, vuto nthawi zambiri limakhala kusapeza chitoliro chachitsulo chokhala ndi mankhwala ofanana. Vuto lenileni ndikuonetsetsa kuti zinthuzo zikuvomerezeka pansi pamuyezo wofunikira ndi tsatanetsatane wa polojekiti.
SANONPIPE ikhoza kuthandiza makasitomala ndi:
●Chitoliro chachitsulo chopanda msoko cha ASTM A335 P11
●Chitoliro chachitsulo chosasunthika cha ASTM A335 P22
●Magiredi ena a ASTM A335 Cr-Mo
●Magiredi achitsulo a European Cr-Mo alloy
●Kuyerekeza zinthu za msika wa China ndi Russia
●Kuwunikanso kwa ukadaulo
●Chitsimikizo cha zinthu ndi kukula kwake
●MTC ndi kutsata
●Kugwirizana kwa hydrostatic ndi NDE
●Kuyang'ana kwa chipani chachitatu
