Iipayipi ze-ASTM A53 zeBanga B: Imigangatho elinganayo kwi-EN, DIN, kunye ne-JIS

I-ASTM A53 Grade B (ekwabizwa ngokuba yiI-ASTM A 53 Ibanga BokanyeI-A53 GrB) iseyenye yezona nkcukacha zepayipi zentsimbi yekhabhoni ezaziwayo kwihlabathi liphela. Isetyenziswa kakhulu kwi ukuhanjiswa kwamanzi, ioyile negesi, imibhobho yolwakhiwo, iinkqubo zoomatshini, kunye nemibhobho yebhoyila.

Kodwa xa iiprojekthi zamazwe ngamazwe zixuba imigangatho, abathengi ngokungathandabuzekiyo bayabuza:

"Yintoni iI-ASTM A53izinto ezifanayo kwi-EN, DIN okanye JIS?

Esi sikhokelo sandisa uthelekiso, sazisa amanqanaba esinyithi alinganayo, sichaza umahluko wokuvavanya, kwaye sikuncede uvavanye ukutshintshwa xa ukhangelaUmbhobho wentsimbi we-ASTM A53, umbhobho ongenamthungo, okanye izinto ezitshintshayo.

Ukuqonda i-ASTM A53 Grade B: Iimpawu eziphambili

Izigqubuthelo ze-ASTM A53/A53Mumbhobho wentsimbi ongenamthungo (Uhlobo S)kwayeUmbhobho odibeneyo we-ERW(Uhlobo E)ngenjongo ngokubanzi.

✔ Amandla e-ASTM A53 Grade B aphakathi ukuya phezulu, asetyenziswa rhoqo kwimisebenzi yokuthutha ulwelo kunye nokuthwala uxinzelelo.

Uluhlu lweeKhemikhali (ASTM A53 Gr B):

Ikhabhoni ≤ 0.30%

IManganese ≤ 1.20%

I-phosphorus ≤ 0.05%

Isalfure ≤ 0.045%

Iipropati zoomatshini:

Amandla okuThamba ≥I-415 MPa

Amandla Okuvelisa ≥240 MPa

Ukwandiswa ≥20%

Izinto ezilinganayo ze-ASTM A53 GrB kwi-EN, DIN kunye ne-JIS

Ezi nqanaba zihambelana ngokusondeleyo nezinto ezilinganayo ze-ASTM A53 ngokubhekiselele kumandla, ukwakheka kwekhabhoni kunye neempawu zokwandiswa.

Kutheni Banjalo?Ziyathelekiswa?

I-EN P235GH→ Imveliso: ~235 MPa, Ukutsalwa: 360–500 MPa — phantse kufana ne-ASTM A53 Grade B.

I-JIS STPG410→ Inqanaba lekhabhoni elifanayo kunye nobude — ifanelekile kwizicelo ezifuna ukumelana noxinzelelo kunye nokudityaniswa.

Ke ngoko, ezi zinto zinokuthathwa njenge-ASTM A53 GrB ngokubanzi, ingakumbi kwiibhoyila, iipayipi zolwakhiwo kunye nezoxinzelelo.

I-ASTM A53 vs ASTM A106 vs API 5L — Ukudideka Okuqhelekileyo Kwabathengi

Iinjineli ezininzi zamazwe ngamazwe azikhangeli nje kuphela"Ixabiso elilinganayo le-A53 GrB"kodwa buza kwakhona:

✔ “Ingaba i-ASTM A106 ilingana ne-ASTM A53?”
✔ “Ingaba i-API 5L ilingana ne-A53 GrB?”

Impendulo: akunjalo kanye.

Ngoko ke yintonile I-ASTM A106 Grade B kwayeI-API 5L Gr B zihlala zicatshulwa, baziiindlela ezahlukeneyo, kungekhona ukulingana okungqongqo.

Umahluko kwiMveliso ubalulekile

Nokuba izinto ezilinganayo ze-ASTM A53 ziyafana ngokweekhemikhali, imithetho yokuhlola yahlukile:

I-ASTM A53 Ibanga B

Uvavanyo lwe-hydrostatic

I-NDT yee-weld seams

Uvavanyo lokugoba/lokuthamba

Igubungela zombiniI-ERW kwaye ayinamthungo

Yingakho uza kubona rhoqo amagama okufumana izinto ezifana nombhobho wentsimbi we-ASTM A53 ERW xa ucacisa iinguqulelo ezidibeneyo.

I-EN P235GH / P235TR

Iimfuneko ezongezelelweyo zovavanyo lwempembelelo

Amaxwebhu angakumbi omthungo wokuwelda

I-DIN 1629

Ukunyamezelana okungqongqo kwiipayipi ezingenamthungo

I-JIS G3454

Ukusebenza okufanelekileyo kwizicelo zebhoyila kunye nemibhobho yoxinzelelo

Ungaqinisekisa njani ukulingana kwimigangatho yonke?

✔ Thelekisa amaxabiso oomatshini kunye neekhemikhali (±5% yokunyamezelana kwamkelekile)

✔ Cela izatifikethi ezifomathiweyo ze-MTC okanye ze-EN/DIN/JIS

✔ Ukuhlolwa komntu wesithathu (njenge-SGS / BV / TÜV) ukuze kufunyanwe ukuqinisekiswa okusemgangathweni oqhelekileyo

Le nkqubo inciphisa umngcipheko xa kukhethwaIzinto ezilinganayo ze-ASTM A53kwiiprojekthi zehlabathi.
