ASTM A500 Grade B Introduction

ASTM A500 ʻo ia ka paipu kalapona kila i hoʻoheheʻe ʻia a hoʻoheheʻe ʻia no nā alahaka i hoʻopaʻa ʻia, hoʻopaʻa ʻia, a i ʻole i hoʻopaʻa ʻia a me nā hale kūkulu hale a me nā kumu hana maʻamau.

Papa BHe paipu kalapona kila i hana ʻia me ka ikaika ʻaʻole emi ma lalo o 315 MPa [46,000 psi] a me ka ikaika tensile ʻaʻole i emi iho ma mua o 400 MPa [58,000], i hoʻohana ʻia i nā ʻano hana hale like ʻole. a me nā papahana hoʻolālā mechanical ma muli o kona kūpaʻa a me ka lōʻihi.

ʻO ka helu helu ASTM A500

Hoʻokaʻawale ʻo ASTM A500 i ka paipu kila i ʻekolu mau papa,papa B,papa C, a me ka papa D.

ASTM A500 Nui Lahi

 

No na paipu meanawaena waho ≤ 2235mm [88in]amānoanoa o ka pā ≤ 25.4mm [1in].

Eia nō naʻe, inā hoʻohana ʻia ke kaʻina hana hoʻoheheʻe ERW, hiki ke hana ʻia nā paipu me ke anawaena kiʻekiʻe o 660 mm a me ka mānoanoa pā o 20 mm.

Inā makemake ʻoe e kūʻai i ka paipu me ka mānoanoa o ka paia o ke anawaena, hiki iā ʻoe ke koho e hoʻohana i ke kaʻina hana kuʻihao SAW.

ʻO ASTM A500 Grade B Hollow Section Form

CHS: Nā ʻāpana hollow pōʻai.

RHS: ʻAha a i ʻole ʻāpana ʻāpana ʻehā.

EHS: Nā ʻāpana hollow Elliptical.

Mea Maka

 

E hana ʻia ke kila e kekahi a ʻoi aku paha o kēia mau hana.oxygen kumu a i ʻole ka umu uila.

Ke Kaʻina Hana Oxygen Basic: He ala wikiwiki kēia o ka hana kila, e hōʻemi ana i ka ʻike kalapona ma ka puhi ʻana i ka oxygen i loko o ka hao puaʻa i hoʻoheheʻe ʻia ʻoiai e wehe ana i nā mea makemake ʻole e like me ka sulfur a me ka phosphorus.He kūpono ia no ka hana wikiwikiʻana i nā mea kila nui.

Ke Kaʻina Hana Uhi Uila: Ke hoʻohana nei ke Kaʻina Hana Uila Uila i ke arc wela wela e hoʻoheheʻe ai i ka ʻōpala a hoʻemi pololei i ka hao, a he mea pono loa ia no ka hana ʻana i nā māka kūikawā a me ka hoʻomalu ʻana i nā haku mele, a me ka hana liʻiliʻi.

Ka Hana Hana o ASTM A500

E hana ʻia nā paipu e kauila-kūʻai-welded (RW)kaʻina hana.

ʻO ka paipu ERW ke kaʻina hana o ka weld ma ka wili ʻana i kahi mea metala i loko o ka cylinder a hoʻohana i ke kūpaʻa a me ke kaomi ma kona lōʻihi.

ERW Ke Kaʻina Hana Hana Hana Kiʻi

Hana wela o ka ASTM A500 Papa B

 

Hiki ke hoʻopaʻa ʻia a hoʻomaha ʻia paha nā paipu pae B.

Hoʻohui kemika o ASTM A500 Grade B

ʻO ASTM A500 Grade B_Koi Kemika

ʻO ka hui kemika o ke kila ASTM A500 Grade B ka nui o ke kalapona a me ka manganese e hōʻoia i nā waiwai mechanical maikaʻi a me ka weldability.I ka manawa like, hoʻopaʻa paʻa ʻia nā pae phosphorus a me ka sulfur e pale i ka embrittlement, a ʻo ka hoʻohui haʻahaʻa o ke keleawe e hoʻomaikaʻi i ka pale ʻana i ka corrosion.

Ua kūpono kēia mau waiwai no nā noi hoʻolālā, ʻoi aku hoʻi i nā wahi kahi e pono ai ka weldability maikaʻi a me ka lōʻihi.

Nā Waiwai Ui o ASTM A500 Papa B

 

E hoʻokō nā mea hoʻohālike i nā koi pili o ASTM A370, Pākuʻi A2.

[50 mm] = 61t+ 12, hoʻopuni ʻia i ka pākēneka kokoke loa.No ka A500M e hoʻohana i kēia ʻano kumu: 2.4t+ 12, hoʻopuni ʻia i ka pākēneka kokoke loa.
CHoʻopili wale ʻia nā helu elongation liʻiliʻi i nā hoʻāʻo i hana ʻia ma mua o ka hoʻouna ʻia ʻana o ka paipu.

Ho'āʻo palahalaha oNā Paipu Kūleʻa Poʻe i Weled

 

Welddutilitytest: Me ka hoohana ana i kekahi mea hoike ma kahi o 4 iniha (100 mm) ka loa, e palahalaha me ka weld ma 90° a hiki i ke kuhikuhi o ka hoouka ana a hiki i ka emi ana o ka mamao mawaena o na papa malalo o 2/3 o ke anawaena o waho o ka paipu.ʻaʻole nahā a nahā paha ka mea hoʻohālike ma loko a ma waho paha i kēia kaʻina hana.

ʻO ka hoʻāʻo ductility paipu: e hoomau i ka hoopalahalaha ana i ke kikoo a hiki i ka emi ana o ka mamao mawaena o na papa malalo o 1/2 o ke anawaena o waho o ka paipu.i kēia manawa, ʻaʻole pono e loaʻa i ka paipu nā māwae a i ʻole nāha ma ka ʻaoʻao o loko a me waho.

Pono ponotest: E hoʻomau i ka hoʻopalapala i ke ʻano a hiki i ka wā e haki ai a i ʻole e hoʻokō ʻia nā koi o ka mānoanoa pā pili.Inā ʻike ʻia nā hōʻike o ka ʻili ʻana o ka ply, nā mea paʻa ʻole, a i ʻole nā ​​​​welds piha ʻole i ka wā o ka hoʻāʻo ʻana, e noʻonoʻo ʻia ka mea hōʻike ʻaʻole ʻoluʻolu.

Hoʻāʻo ʻana i ke ahi

 

Loaʻa ka hoʻāʻo ʻana no nā paipu poepoe ≤ 254 mm (10 in) ke anawaena, akā ʻaʻole pono.

ʻAʻole hemahema nā paipu a pau a e like me ka mea hana.

E helu ʻia nā hemahema o ka ʻili i nā hemahema ke hoʻemi ko lākou hohonu i ke koena o ka mānoanoa o ka pā i lalo o 90% o ka mānoanoa pā i kuhikuhi ʻia.

Hiki ke hoʻopau loa ʻia nā hemahema a hiki i ka 33% o ka mānoanoa o ka pā i ʻōlelo ʻia ma ka ʻoki ʻana a i ʻole ka wili ʻana e hoʻopau i ka metala.
Inā hoʻohana ʻia ka hoʻopihapiha hoʻopihapiha, e hoʻohana ʻia ke kaʻina hana kuʻihao pulu a e hoʻoneʻe ʻia ka mea hoʻoheheʻe ʻia e hoʻopaʻa i kahi ʻili maʻemaʻe.

ʻAʻole i manaʻo ʻia nā hemahema o ka ʻili, e like me ka hoʻohana ʻana i nā māka, nā ʻōpala liʻiliʻi a i ʻole nā ​​​​hōʻailona ʻōwili, a i ʻole nā ​​lua pāpaʻu, inā hiki ke wehe ʻia i loko o ka mānoanoa o ka pā i kuhikuhi ʻia.

Hoailona Paipu

 

Pono e hoʻokomo i kēia mau ʻike:

Ka inoa o ka mea hana: Hiki i kēia ke inoa piha o ka mea hana a i ʻole ka pōkole.

Brand a i ʻole ka Palapala Kūʻai: Ka inoa inoa a i ʻole ka hōʻailona i hoʻohana ʻia e ka mea hana e hoʻokaʻawale i kāna huahana.

Mea hoʻolālā kikoʻī: ASTM A500, ʻaʻole pono e hoʻokomo i ka makahiki o ka paʻi ʻana.

Palapala Papa: Papa B, C a i ole D.

No nā paipu hana ≤ 100mm (4in) ke anawaena, hiki ke hoʻohana ʻia nā lepili e hōʻailona i ka ʻike ʻike maopopo.

Hoʻohana i ka ASTM A500 Grade B

 

Hoʻohana mua ʻia no nā kumu hoʻolālā, hāʻawi ia i ka ikaika mechanical pono a me ka weldability e kākoʻo i ka hoʻolālā ʻana a me ke kūkulu ʻana i nā hale hoʻolālā a me nā ʻenehana.

Hoʻohana nui ʻia kēia paipu kila i ke kūkulu ʻana i nā papa, nā alahaka, nā ʻoihana ʻoihana, a me nā ʻano mea like ʻole e pono ai ka ikaika a me ka lōʻihi.

Nā Kūlana Pili

 

ASTM A370: Nā ʻano hoʻāʻo a me nā wehewehe no ka hoʻāʻo ʻana i ka mīkini o nā huahana kila.
ASTM A700: Alakaʻi no ka Packaging, Marking, and Loading Methods for Steel Products for Shipment.
ASTM A751: Nā ʻano hoʻāʻo a me nā hoʻomaʻamaʻa no ka hoʻāʻo ʻana i kemika o nā huahana kila.
ʻO ka huaʻōlelo ASTM A941 e pili ana i ke kila, ke kila kila, nā huila pili, a me nā Ferroalloys.

Loaʻa nā ʻano o ka uhi ʻili

 

E like me nā koi o nā mea kūʻai aku, hiki ke hana i ka anti-corrosion treatment o nā paipu kila ma nā ʻano like ʻole e hoʻonui ai i kona kūpaʻa corrosion a hoʻolōʻihi i kona ola lawelawe.
Me ka varnish, pena, galvanization, 3PE, FBE, a me nā ʻano hana ʻē aʻe.

ʻO kā mākou pono

 

ʻO mākou kahi mea hana kiʻekiʻe kiʻekiʻe welded carbon steel paipu a me ka mea hoʻolako mai Kina, a me kahi mea hoʻoheheʻe paipu kila maʻemaʻe, hāʻawi iā ʻoe i kahi ākea o nā paipu kila!

Inā makemake ʻoe e ʻike hou aku e pili ana i nā huahana paipu kila, hiki iā ʻoe ke hoʻokaʻaʻike mai iā mākou!
