ʻO ASTM A501 Papa B LSAW ʻO ke kila kabone Structural paipu

ʻO ka wehewehe pōkole:

Kūlana hoʻokō: ASTM A501
Papa: B
Nui o ka paipu poepoe: 25-1220 mm [1-48 in ]
Mānoanoa pā: 2.5-100 mm [0.095-4 in]
Length: ʻO ka lōʻihi ka hapa nui o 5-7m [16-22 ft] a i ʻole 10-14m [32-44 ft], akā hiki ke kuhikuhi ʻia.
ʻO ka hopena o ka paipu: ka welau palahalaha.
Ka uhi ʻana o ka ʻili: galvanized a ʻeleʻele paipu (paipu ʻaʻole hāʻawi ʻia i ka zinc-coating)
Nā lawelawe hou aku: nā lawelawe maʻamau e like me ka ʻoki ʻana i ka paipu, ka hoʻoheheʻe ʻana i ka hopena o ka tube, ka hoʻopili ʻana, etc.

ʻO ASTM A501 Papa B Hoʻomaka

ASTM A501 Papa Bhe paipu kila kalapona i hoʻopili ʻia me ka liʻiliʻi loa o 448 MPa (65,000 psi) no nā ʻano hana like ʻole.

ASTM A501no ka hana ʻana a me ka hana ʻana i nā paipu kila kalapona i hoʻohui ʻia me ka wela no ka hoʻolālā ʻana.
Hiki i kēia mau paipu kila ke ʻeleʻele (ʻaʻole i uhi ʻia) a i ʻole ka wela wela, ʻo ia ka mea i hoʻonui i ka pale ʻana i ka corrosion ma o ke kaʻina hana galvanizing, e kūpono ana i kahi ākea ākea.
Hoʻohana nui ʻia kēia mau paipu kila i nā alahaka, nā hale, a me nā mea hana maʻamau.

ʻO ka papa helu helu ASTM A501

Hoʻokaʻawale ʻo ASTM A501 i ka paipu kila i ʻekolu mau papa,papa A, papa B, a me ka papa C.

ʻO ka papa B ka mea i hoʻohana nui ʻia ma waena o nā papa ʻekolu no ka mea hāʻawi ia i nā waiwai kaulike maikaʻi no nā noi hoʻolālā he nui.

Mea Maka

 

E hana ʻia ke kila ekumu-oxygen a i ʻole uila-arc-furnace kaʻina hana kila.

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

Ke hoʻoheheʻe ʻia nā kila o nā māka like ʻole, e ʻike ka mea hana kila i ka mea hoʻololi i hopena a hoʻoneʻe iā ia me kahi kaʻina hana i hoʻokaʻawale maikaʻi i nā māka.

Ke Kaʻina Hana Hana o ASTM A501

E hana ʻia ka paipu e kekahi o kēia mau hana:holoʻokoʻa;kapuahi-weli-weli (continuous welding);wiliwili pale uila (ERW) a i ʻole wiliwili arc submerged (SAW)a ukali ʻia e ka hoʻomaʻamaʻa ʻana a puni ka ʻāpana keʻa a me ka hana wela ma ke kaʻina hana hoʻohaʻahaʻa a hoʻohua paha, a i ʻole nā ​​mea ʻelua.

Hoʻokaʻawale ʻia ke kaʻina hana welding SAW iLSAW(SAWL) a me SSAW (HSAW).

E hana ʻia ka hana ʻano hope ma ke kaʻina hana wela.

Hana wela o ASTM A501 Papa B

E ʻae ʻia ka hoʻohui ʻana i kahi lapaʻau wela maʻamau no nā paipu me ka mānoanoa pā i ʻoi aku ma mua o 13mm [1/2 in].
