Amapayipi e-ASTM A53 Grade B: Amazinga Alinganayo ku-EN, DIN, kanye ne-JIS

I-ASTM A53 Ibanga B (elibizwa nangokuthiI-ASTM A 53 Ibanga BnomaI-A53 GrB) isalokhu ingenye yezimpawu zepayipi lensimbi yekhabhoni ezaziwa kakhulu emhlabeni jikelele. Isetshenziswa kabanzi e- ukudluliswa kwamanzi, uwoyela negesi, amapayipi okwakha, izinhlelo zemishini, kanye namapayipi ebhoyila.

Kodwa uma amaphrojekthi aphesheya ehlanganisa amazinga, abathengi bayabuza:

"KuyiniI-ASTM A53izinto ezifanayo ku-EN, DIN noma JIS?

Lo mhlahlandlela wandisa ukuqhathanisa, wethula amamaki ensimbi alinganayo, uchaza umehluko wokuhlola, futhi ukusize uhlole ukushintshana lapho utholaIpayipi lensimbi le-ASTM A53, ipayipi elingenamthungo, noma ezinye izinto zokufaka esikhundleni salo.

Ukuqonda i-ASTM A53 Ibanga B: Izici Eziyinhloko

Izembozo ze-ASTM A53/A53Mipayipi lensimbi elingenamthungo (Uhlobo S)futhiIpayipi elihlanganisiwe le-ERW(Uhlobo E)ngenhloso evamile.

✔ Izinga lamandla le-ASTM A53 Grade B liphakathi nendawo, ngokuvamile lisetshenziswa emisebenzini yokuthutha uketshezi kanye nokuthwala ingcindezi.

Uhla Lwamakhemikhali (ASTM A53 Gr B):

Ikhabhoni ≤ 0.30%

I-Manganese ≤ 1.20%

I-Phosphorus ≤ 0.05%

Isibabule ≤ 0.045%

Izakhiwo Zemishini:

Amandla Okudonsa ≥415 MPa

Amandla Okukhiqiza ≥240 MPa

Ukwelulwa ≥20%

Izinto Ezilinganayo ze-ASTM A53 GrB ku-EN, DIN kanye ne-JIS

Lawa mabanga ahambisana kakhulu nezinto ezilinganayo ze-ASTM A53 maqondana namandla, ukwakheka kwekhabhoni kanye nezakhiwo zokwelulwa.

Kungani Benjalo?Zingaqhathaniswa?

I-EN P235GH→ Isivuno: ~235 MPa, Ukuthambekela: 360–500 MPa — cishe kufana ne-ASTM A53 Grade B.

I-JIS STPG410→ Izinga lekhabhoni elifanayo kanye nokwelulwa — kulungele izinhlelo zokusebenza ezifuna ukumelana nengcindezi kanye nokushintshwa.

Ngakho-ke, lezi zinto ngokuvamile zingabhekwa njenge-ASTM A53 GrB, ikakhulukazi kumapayipi ebhoyila, esakhiwo kanye nengcindezi.

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

Onjiniyela abaningi bamazwe ngamazwe abagcini nje ngokufuna“Okulingana ne-A53 GrB”kodwa futhi ubuze:

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

Impendulo: akunjalo neze.

Ngakho-ke yinile I-ASTM A106 Grade B futhiI-API 5L Gr B kuvame ukucashunwa, kunjaloizinketho ezihlukile, hhayi ukulingana okuqinile.

Umehluko Wokukhiqiza Ubalulekile

Noma ngabe izinto ezilinganayo ze-ASTM A53 zifana ngamakhemikhali, imithetho yokuhlola iyahluka:

I-ASTM A53 Ibanga B

Ukuhlolwa kwe-hydrostatic

I-NDT yemithungo yokushisela

Ukuhlolwa kokugoba/ukuthamba

Ihlanganisa kokubiliI-ERW futhi ayinazihibe

Yingakho uzobona njalo amagama okuthola izinto njengepayipi lensimbi le-ASTM A53 ERW uma ucacisa izinhlobo ezihlanganisiwe.

I-EN P235GH / P235TR

Izidingo ezengeziwe zokuhlolwa komthelela

Imibhalo eminingi yomthungo wokushisela

I-DIN 1629

Ukubekezelelana okuqinile kobukhulu bamapayipi angenamthungo

I-JIS G3454

Ukusebenza okufanelekela ukusetshenziswa kwamapayipi ebhoyila kanye nengcindezi

Ungaqinisekisa Kanjani Ukulingana Kuzo Zonke Izindinganiso?

✔ Qhathanisa amanani emishini namakhemikhali (ukubekezelelana okungu-±5% kuyamukeleka)

✔ Cela izitifiketi ezifomethiwe ze-MTC noma ze-EN/DIN/JIS

✔ Ukuhlolwa komuntu wesithathu (njenge-SGS / BV / TÜV) ukuze kuqinisekiswe okujwayelekile

Le nqubo inciphisa ubungozi lapho kukhethwaIzinto ezilinganayo ze-ASTM A53kumaphrojekthi omhlaba wonke.

KunganiI-YUANTAI DERUNUngumhlinzeki Othembekile we-ASTM A53

Njengoba ineminyaka engaphezu kwengu-20 yesipiliyoni sokukhiqiza, i-YUANTAI DERUN inikeza:
