Mapaipi a ASTM A53 Giredi B: Miyezo Yofanana mu EN, DIN, ndi JIS

ASTM A53 Giredi B (yomwe imatchedwanso kutiASTM A 53 Giredi BkapenaA53 GrB) ikadali imodzi mwa njira zodziwika bwino kwambiri zoyezera mapaipi a chitsulo cha kaboni padziko lonse lapansi. Imagwiritsidwa ntchito kwambiri mu kutumiza madzi, mafuta ndi gasi, mapaipi omangira, makina, ndi mapaipi a boiler.

Koma pamene mapulojekiti apadziko lonse akuphatikiza miyezo, ogula amafunsa kuti:

"Kodi ndi chiyaniASTM A53zinthu zofanana mu EN, DIN kapena JIS?

Bukuli likukulitsa kufananiza, likuwonetsa magiredi ofanana achitsulo, limafotokoza kusiyana kwa kuyesa, ndipo limakuthandizani kuwona kusinthana mukapeza zinthu.Chitoliro chachitsulo cha ASTM A53, chitoliro chopanda msoko, kapena zinthu zina zolowa m'malo.

Kumvetsetsa ASTM A53 Giredi B: Makhalidwe Ofunika

Zikuto za ASTM A53/A53Mchitoliro chachitsulo chopanda msoko (Mtundu S)ndiChitoliro cholumikizidwa cha ERW(Mtundu E)pa cholinga chachikulu.

✔ Mphamvu ya ASTM A53 Giredi B ndi yapakatikati mpaka yapamwamba, nthawi zambiri imagwiritsidwa ntchito poyendetsa madzi ndi ntchito zonyamula kupanikizika.

Mtundu wa Mankhwala (ASTM A53 Gr B):

Mpweya ≤ 0.30%

Manganese ≤ 1.20%

Phosphorus ≤ 0.05%

Sulfure ≤ 0.045%

Katundu wa Makina:

Mphamvu Yokoka ≥415 MPa

Mphamvu Yopereka ≥240 MPa

Kutalika ≥20%

Zipangizo Zofanana za ASTM A53 GrB mu EN, DIN & JIS

Magulu awa amagwirizana kwambiri ndi zinthu zofanana ndi ASTM A53 pankhani ya mphamvu, kapangidwe ka kaboni ndi mawonekedwe ake otalikirapo.

Chifukwa Chake IwoZili Zofanana?

EN P235GH→ Kuchuluka: ~235 MPa, Kumangirira: 360–500 MPa — pafupifupi kufanana ndi ASTM A53 Giredi B.

JIS STPG410→ Mlingo wofanana wa kaboni ndi kutalika kwake — ndibwino kugwiritsa ntchito pofuna kukana kupanikizika ndi kusinthasintha.

Chifukwa chake, zipangizozi nthawi zambiri zimatha kuonedwa ngati ASTM A53 GrB, makamaka m'mapaipi a boiler, structural ndi pressure.

ASTM A53 vs ASTM A106 vs API 5L — Kusokonezeka Kofala kwa Ogula

Mainjiniya ambiri apadziko lonse lapansi samangofuna"Zofanana ndi A53 GrB"komanso funsani kuti:

✔ “Kodi ASTM A106 ndi yofanana ndi ASTM A53?”
✔ “Kodi API 5L ndi yofanana ndi A53 GrB?”

Yankho: sichoncho kwenikweni.

Kotero chiyanile ASTM A106 Grandi B ndiAPI 5L Gr B nthawi zambiri amatchulidwa, alinjira zina, osati zofanana kwambiri.

Kusiyana kwa Kupanga Zinthu N'kofunika

Kodi Mungatsimikizire Bwanji Kufanana Pakati pa Miyezo?

✔ Yerekezerani kuchuluka kwa makina ndi mankhwala (± 5% yovomerezeka)

✔ Pemphani satifiketi ya MTC kapena EN/DIN/JIS yokonzedwa

✔ Kuyang'aniridwa ndi anthu ena (monga SGS / BV / TÜV) kuti atsimikizire kuti zinthuzo ndi zolondola

Ndi zaka zoposa 20 zaukadaulo wopanga, YUNTAI DERUN imapereka:

✔ Chitoliro chachitsulo cha ASTM A53 ERW
✔ Chitoliro chopanda msoko cha ASTM A53 GrB
✔ mapaipi a chitsulo cha kaboni ofanana ndi EN / DIN / JIS

Timatsimikiza kuti:

Satifiketi Yokhazikika

Kaya makasitomala atchula zinthu zofanana ndi ASTM A53, ASTM A106, API 5L, kapena A53 GrB, YUANTAI DERUN imapereka mayankho ofanana ndi ntchito yabwino kwambiri.

Maganizo Omaliza

Kumvetsetsa miyezo yofanana ya ASTM A53 Giredi B ndikofunikira kwambiri pakugula padziko lonse lapansi.

Kumvetsetsa momwe chitoliro chachitsulo cha ASTM A53 ERW chikufananira ndi chitoliro cha ku Europe cha P235GH kapena cha ku Japan cha STPG410 kumathandiza ogula:

✔ kupewa zolakwika za specifications
✔ kuchepetsa kuchedwa kwa satifiketi
