Paipu kila humuhumu EN 10210 S275J2H: Alakaʻi ʻenehana piha

Hoʻolauna

ʻO ka paipu wili kila kūkulu EN 10210 S275J2H kahi papa kila kūkulu ʻole-alloy maʻamau ma lalo o ke kūlana ʻEulopa EN 10210-1, hoʻohana nui ʻia i nā hale kūkulu, ka ʻenekinia alahaka, ka hana mīkini, a me nā papahana ʻoihana ma ka honua holoʻokoʻa.

Nīnau pinepine nā ʻenekinia a me nā loea kūʻai: "He aha ka mea S275J2H?", "He aha ka mea like me ka S275J2H ma Kina?", a "He aha ke kumukūʻai o ka paipu humuhumu EN 10210 S275J2H no kēlā me kēia tona?" Hāʻawi kēia ʻatikala i kahi alakaʻi loea piha e pili ana i ka hoʻolālā ʻana o ka papa, ka haku mele kemika, nā waiwai mechanical, nā noi, a me nā noʻonoʻo kūʻai.

01 He aha ka mea S275J2H?

Ka Wehewehe ʻana i ka Hoʻonohonoho Papa

He papa kila kūkulu ʻole ʻo S275J2H ma lalo o ke kūlana EN 10210-1, i hana kūikawā ʻia no nā ʻāpana hakahaka kūkulu i hoʻopau wela ʻia. Loaʻa i kēlā me kēia huapalapala i ka hoʻolālā papa ke ʻano loea kikoʻī:

ʻAno Manaʻo
S Ke kila kūkulu
275 ʻO ka ikaika haʻahaʻa loa o 275 MPa no ka mānoanoa o ka paia ≤ 16mm
J2 Ka ikehu hopena ≥ 27J ma -20°C (paʻakikī wela haʻahaʻa)
H Kūpono no nā ʻāpana Hollow (hoʻopau wela ʻia)

ʻO ka helu mea i koho ʻia no S275J2H ʻo ia1.0138, a ua hana ʻia ia ma ke ʻano he kila i pepehi piha ʻia (FF) e hōʻoia i nā waiwai like a me ka hiki ke hoʻopili maikaʻi ʻia.

Kūlana Pili

Hana ʻia ka paipu wili ʻole S275J2H e like meEN 10210-1:2006– "Nā ʻāpana hakahaka hoʻolālā wela i hoʻopau ʻia o nā kila ʻaʻole-alloy a me nā kila palaoa maikaʻi - Nā kūlana hoʻouna loea".

Nā koi koʻikoʻi i uhi ʻia e kēia kūlana:

  • Nā palena o ka haku mele kemika (ka nānā ʻana i ka ladle)
  • Nā waiwai mechanical e ka mānoanoa o ka paia
  • Nā hoʻomanawanui ana
