Ukugqithisa kwe-ASTM A106/ASME SA106 Umbhobho

I-ASTM A106/ASME SA106 yinkcazo esemgangathweni yombhobho we-carbon steel engenamthungo osetyenziswa kwiinkonzo zobushushu obuphezulu. Ibandakanya amabakala amathathu A, B kunye no-C, kunye nebakala lokusetyenziswa okuqhelekileyo ngu-A106 iBanga B. Isetyenziswe kumashishini ahlukeneyo kungekuphela nje kwiinkqubo zemibhobho efana ne-oyile negesi, amanzi, ukuhanjiswa kodaka lwezimbiwa, kodwa nakwibhoyila, ulwakhiwo, iinjongo zesakhiwo.

Ukwakheka kweekhemikhali kwi%

● ICarbon (C) Max KwiBanga A 0.25, kwiBanga B 0.30, iBanga C 0.35
● IManganese (Mn): 0.27-0.93, 0.29-1.06
● Isulfure (S) Ubuninzi: ≤ 0.035
● I-Phosphorus (P) : ≤ 0.035
● I-Silicon (Si) Min : ≥0.10
● IChrome (Cr): ≤ 0.40
● Ubhedu (Cu): ≤ 0.40
● I-Molybdenum (Mo): ≤ 0.15
● I-Nickel (Ni): ≤ 0.40
● Vanadium (V): ≤ 0.08

Nceda qaphela:
Kunciphiso ngalunye lwe-0.01% kwi-carbon element ephezulu, ukunyuka kwe-0.06% ye-manganese ngaphezu kwexabiso elichaziweyo kuya kuvunyelwa, kwaye ukuya kuthi ga kwi-1.35 ephezulu.
I-Elements Cr, Cu, Mo, Ni, V edibeneyo ayiyi kudlula i-1%.

I-ASTM A106 yeBanga B Amandla okuZimba kunye nokomelela kweSivuno

Ifomula yokwandisa:
Kwi-2 in. [50mm], iya kubalwa ngokuthi: e = 625 000 A^0.2 / U^0.9
Ngeeyunithi ze-inch-pound, e = 1940 A^0.2 / U^0.9
Iingcaciso ze-e, A, kunye no-U, nceda ufumane apha. (Equation iyafana neASTM A53, API 5L umbhobho.)
Amandla e-Tensile, min, psi [MPa] IBanga A 48,000 [330], iBanga B 60,000 [415], iBanga C 70,000 [485]
Amandla eSivuno ubuncinane kwi-psi [MPa] iBanga A 30,000 [205], B 35,000 [240], C 40,000 [275]
Ukwandiswa kwi-2 kwi (50mm), ubuncinane bepesenti %
Kuzo zonke iisayizi ezincinci ezivavanyiweyo kwicandelo elipheleleyo, iimvavanyo zohambo ezisisiseko ezisezantsi zobude obunqamlezileyo: IBakala A Longitudinal 35, Transverse 25; B 30, 16,5; C 30, 16,5;
Kwimeko eqhelekileyo umjikelo 2 intshi gage ubude isampulu uvavanyo isetyenziswa, amaxabiso ngasentla zezi: Grade A 28, 20; B 22, 12; C 20, 12.

IShedyuli yeMilinganiselo yeMibhobho ye-ASTM A106 yeBakala B

Umgangatho ugubungela ubungakanani bombhobho kwi-NPS (i-Standard Standard Straight) ukusuka kwi-1/8 intshi ukuya kwi-intshi engama-48 (10.3mm DN6 - 1219mm DN1200), ngeli xesha ithotyelwe ubukhulu bodonga oluqhelekileyo lomgangatho we-ASME B 36.10M. Kwezinye iisayizi ngaphandle kwe-ASME B 36.10M nayo ivumelekile ukusebenzisa olu lwazi lusemgangathweni.

Iimpahla ezingekasilwa

Izinto ezisetyenzisiweyo kwi-ASTM A106 ingcaciso esemgangathweni iya kusetyenziswa ukugoba, ukujika, okanye iinkqubo ezifanayo zokubumba. Kwimeko yokuba izinto zensimbi zifakwe kwi-welding, inkqubo ye-welding kufuneka ifaneleke kweli nqanaba le-ASTM A106, kwaye lisebenza kwindawo yokusebenza yokushisa okuphezulu.

Apho kukho umgangatho ophezulu okanye ophezulu kwi-ASTM A106 ipayipi yensimbi iyadingeka, umgangatho unenkcazo yokuzikhethela kwiimfuno ezongezelelweyo, kwimibhobho esetyenziswe lo mgangatho. Ngaphezu koko, ezi nkcukacha zongezelelweyo zacela uvavanyo olongezelelweyo, xa iodolo iza kufakwa.
