ASTM A519 Introduction

ASTM A519e hana ʻia ka paipu ma ke kaʻina hana ʻole a hoʻopau wela a hoʻopau anu paha e like me ka mea i ʻōlelo ʻia.

No nā paipu poepoe me ke anawaena o waho ʻaʻole ʻoi aku ma mua o 12 3/4 in (325 mm).

Hiki ke hana 'ia ka paipu kila ma ka huinaha, rectangular, a me na ano e like me ka makemake.

ASTM A519 -2023: Hōʻike maʻamau no ka Seamless Carbon a me Alloy Steel Mechanical Tubing

ʻAno Paipu

Hiki ke hoʻokaʻawale ʻia ʻo ASTM A519 e like me ka mea kila:ʻO ka hao haoa me Alloy Steel.

Ke kila kalaponaua maheleia iCarbon Haʻahaʻa MT(Tubing Mechanical),Kiekie Carbon SteelaDesulfurized a i ʻole Rephosphorized, a i ʻole nā mea ʻeluaʻO ka hao hao, e kūpono i nā pono ʻoihana like ʻole a me nā hiʻohiʻona noi.

Inā ʻaʻohe māka i kuhikuhi ʻia, loaʻa i nā mea hana ke koho e hāʻawiMT1015 a i ʻole MTX1020nā māka.

Lahi Nui

Ke anawaena o waho: 13.7 - 325 mm;

Mānoanoa pā: 2-100mm.

Mea Maka

Hiki ke hana i ke kila ma kekahi kaʻina hana.

Hiki ke hoʻolei ʻia ke kila i loko o nā ingots a i ʻole ke kaulahao.

Kaʻina Hana Hana

E hana ʻia nā paipu e akaʻina hana ʻolea e hoʻopau wela a hoʻopau anu paha, e like me ka mea i ʻōlelo ʻia.

ʻO nā paipu kila ʻole he paipu me ka wili ʻole ʻia a puni.

ʻO nā paipu anuanuʻōlelo ʻia no nā koi kiʻekiʻe e pili ana i ka pololei o ka dimensional a me ka maikaʻi o ka ʻili.

ʻO ka manaʻo nui o ke kumukūʻai a me ka paʻakikī o nā mea,paipu kila hoʻopau welaʻoi aku paha kahi koho kūpono.

ʻO ka mea aʻe ke kaʻina hana o ka paipu kila seamless wela.

Huina Kemika o ASTM A519

E nānā ka mea hana kila i ka wela o kēlā me kēia kila e hoʻoholo ai i ka pakeneka o nā mea i kuhikuhi ʻia.

Papa 1 Na Koina Kemika o na hao hao haahaa

ʻO ASTM A519 Papa 1 Nā Koina Kemika o nā kila Haʻahaʻa-Carbon

ʻO ke kila maʻemaʻe he kila me kahi mea kalapona maʻamau ʻaʻole ma mua o 0.25%.Ma muli o ka haʻahaʻa haʻahaʻa o ke kalapona, ʻoi aku ka maikaʻi o ka ductility a me ka malleability o kēia kila a ʻoi aku ka paʻakikī a me ka ikaika e hoʻohālikelike ʻia me ke kila kalapona kiʻekiʻe.

Papa 2 Na Koina Kemika o na hao kalapona e ae

ʻO ASTM A519 Papa 2 Nā Koina Kemika o nā kila kalapona ʻē aʻe

Nā kila kalapona waena: Loaʻa ma waena o 0.25% a me 0.60% carbon, hāʻawi lākou i ka ʻoi aku ka paʻakikī a me ka ikaika a koi aku i ka mālama wela e hoʻomaikaʻi i nā waiwai.

Ke kila kalapona kiʻekiʻe: Loaʻa ma waena o 0.60% a me 1.0% a ʻoi aʻe ke kalapona, a hāʻawi i ka paʻakikī kiʻekiʻe a me ka ikaika, akā haʻahaʻa haʻahaʻa.

Papa 3 Na Koina Kemika no na kila Alloy

ASTM A519 Papa 3 Koi Kemika no na Alloy Steels

Papa 4 Nā Koina Kemika o Resulfurized a Rephosphorized, a i ʻole ʻelua, Carbon Steels

PALAPALA 5 Hoʻomanawanui Huahana Ma luna a Ma lalo paha o ka palena a i ʻole ka palena i ʻōlelo ʻia

Pono e noi ʻia ka mea hana e nānā i ka huahana inā koi ʻia e ke kauoha.
