ASTM A335 Alloy Steel Seamless Paipu

ASTM A335 Alloy Steel Seamless Pipe Kiʻi ʻia

ʻO ka wehewehe pōkole:

Ua kapa pinepine ʻia ʻo ASTM A335 he paipu chrome moly no ka loaʻa ʻana o ke kemika o Molybdenum (Mo) a me Chromium (Cr).Hoʻonui ka Molybdenum i ka ikaika o ke kila a ʻo Chromium (a i ʻole chrome) ka mea nui o ke kila kila.ʻO ka chrome moly alloy steel pipe ka mea i kūpono no ka hoʻohana ʻana i nā mea kanu mana, nā mea hoʻomaʻemaʻe, nā mea kanu kemika, a me nā lawelawe kahua aila kahi e lawe ʻia ai nā wai a me nā kinoea i nā wela kiʻekiʻe loa a me nā kaomi.

Hoʻomaʻamaʻa ʻia ka paipa Alloy Steel no ka hoʻokō ʻana i nā waiwai mechanical e like me ka mea i makemake ʻia.Aia ma lalo kekahi o nā ʻano o ka mālama wela.

Hana maʻamau i ka Quench a me ka Tempering.

Hoʻopiʻi a hoʻohenehene.

Hana maʻamau a paʻakikī.

ʻO Transverse/longitudinal: ʻāwili a palahalaha, paʻakikī, hoʻāʻo piʻo - no nā mea i hoʻomaʻamaʻa ʻia i loko o nā kapuahi puʻupuʻu, e hana ʻia kēia mau hoʻāʻo ma ka 5% o nā paipu mai kēlā me kēia helu wela.No nā ʻāpana liʻiliʻi, pono e hoʻāʻo ʻia kahi paipu ma ka liʻiliʻi.

ASTM A335 Gr.Loaʻa iā P91 ka paʻakikī o 250 HB / 265 HV (25 HRC).

ʻO ka hoʻāʻo wai: e hoʻopili ʻia i kēlā me kēia lōʻihi o ka paipu.

He koho ka ho'āʻo uila non-destructive.
