I-ASTM A210 engenamthungo ye-Carbon Steel Boiler Pipe

I-ASTM A210 Engenamthungo Ipayipi Lebhoyila Lensimbi Yensimbi Isithombe Esifakiwe

Incazelo emfushane:

Izinga le-ASTM A210 limboza amashubhu kabhoyela ensimbi angenamthungo amaphakathi namashubhu okushisa aphezulu.Amapayipi ensimbi e-carbon steel angenamthungo amashubhu okubhayela namapayipi okubhoyela.

Thumela i-imeyili kithi

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Isingeniso Somkhiqizo

Isimo Sokulethwa
I-Annealed, Normalized, Normalized and Tempered.

Ukwelashwa Okungaphezulu
Idiphu kawoyela, iVarnish, Passivation, Phosphating, Shot Blasting.

Isicelo
Ngenhloso ye-boiler ephezulu, ephakathi, nephansi yokucindezela.
Ubude: 5800mm;6000mm;6096mm;7315 mm;11800mm;njalo njalo.
Ubude obukhulu: 25000mm, futhi ukugoba kwe-U kunganikezwa.

Isibonisi somkhiqizo

Ububanzi be-ASTM A210

Lokhu kucaciswa 2 kuhlanganisa ukujiya kodonga oluncane, Insimbi Engenamthungo Ephakathi Nekhabhoni, amashubhu abhayela kanye nesibhayela esibhayela, "amakhava", "1".

Inothi 1 - Lolu hlobo alufanele ukuphela okuphephile nge-forge welding.

Osayizi bamashubhu nobukhulu obuvame ukunikezwa kulokhu kucaciswa buyi-1/2 in. ukuya ku-5 in. [12.7 kuya ku-127 mm] ububanzi obungaphandle kanye no-0.035 ukuya ku-0.500 [0.9 kuya ku-12.7 mm], kuhlanganisa, ubuncane bokujiya odongeni.Amashubhu anobunye ubukhulu angase anikezwe, inqobo nje uma lawo mashubhu ethobela zonke ezinye izimfuneko zalokhu kucaciswa.

Izidingo zezakhiwo zikagesi azisebenzi kumashubhu amancane kuno-1/8 in.

Amanani ashiwo kumayunithi ayintshi yephawundi noma amayunithi e-SI kufanele abhekwe ngokwehlukana njengajwayelekile.Ngaphakathi kombhalo, amayunithi e-SI akhonjiswa kubakaki.Amanani ashiwo ohlelweni ngalunye awafani ncamashi, ngakho-ke, uhlelo ngalunye kufanele;zisetshenziswe ngaphandle kokunye.Ukuhlanganisa amanani asuka kumasistimu womabili kungase kubangele ukungahambisani nokucaciswa.Amayunithi ayintshi yephawundi azosebenza ngaphandle uma igama elithi "M" elishiwo lokhu kucacisiwe liku-oda.

Uku-oda Ulwazi

Ama-oda wezinto ezingaphansi kwalokhu kucaciswa kufanele afake lokhu okulandelayo, njengoba kudingekile, ukuchaza into efiswayo ngokwanele:

Ubuningi (izinyawo, amamitha, noma inombolo yobude), Igama lempahla (amashubhu angenamthungo), Ibanga, Ukukhiqizwa (okuphelile okushisayo noma okubandayo), Usayizi (ububanzi obungaphandle nobukhulu obuncane bodonga), Ubude (okuqondile noma okungahleliwe), Izidingo ozikhethela zona (Izigaba 7 no-10), umbiko wokuhlola uyadingeka, (bona Isigaba Sokugunyazwa Se-Specification A 450/A 450M), Ukuqokwa kokucaciswa, Izidingo ezikhethekile.
