ASTM A53 Papa A me B Paipu kila

ʻO ka ASTM A53 kahi kikoʻī maʻamau no ka paipu kila kalapona i nā nui paipu nominal, i manaʻo ʻia no ka lawe ʻana i ka wai, gas, ea, mahu a no ka hoʻohana ʻana i ka mīkini a me ka hoʻohana ʻana. Uhi ia i ka paipu wiliwili ʻole, ka paipu wili ERW a me ka umu -puʻu paipu wili, i ʻelua pae ikaika (Papa A a me ka Papa B).
Hāʻawi ʻo Octal Pipe i ka ASTM A53 Grade A a me ka Papa B me ka galvanizing koho, nā hopena hopena like ʻole, a me ka palapala wili piha no ka hāʻawi ʻana i ka papahana.

• ʻAno S – Seamless

ʻO ka paipu wela -hoʻopau a i ʻole ke anu{1}}holo ʻole. Manaʻo ʻia no nā ʻōnaehana kaomi, nā mea kanu a me ka lawelawe mechanical kahi e koi ʻia ai ke kūlike ma o ka pā.

• ʻAno E – ERW (Uila -Uila Kū'ē)

ʻO ka paipu wiliwili lōʻihi me ka wela weld -manaʻo ʻia e like me ke koi ʻia e ka ʻōlelo kikoʻī. He koho -kuai kūpono no nā laina wai, nā ʻōnaehana ahi a me nā mea hoʻolālā.

• ʻAno F – Uhi -Kuhi Uila

Loaʻa no ka Papa A wale nō. Hoʻohana ʻia no ka lawelawe hana ʻoi aku ka māmā ma kahi e ʻae ai ka ʻōlelo kikoʻī i kēia kaʻina hana.

• Papa helu

Papa A:ikaika maʻamau no ka lawelawe maʻamau

Papa B:ʻoi aku ka ikaika o ka tensile a me ka hoʻoulu ʻana, i ʻōlelo pinepine ʻia no ke kaomi a me ka hoʻohana mechanical

ʻO ka papa B, me nā waiwai tensile kiʻekiʻe a me nā hua, ʻo ia ka koho maʻamau no nā laina kaomi, nā ʻōnaehana ahi a me ka lawelawe mīkini.

ʻAe ʻo ASTM A53 i nā ala ala ʻole a welded. Wela -paipu lauwili ʻia i ka OD pono a me ka mānoanoa o ka paia. Pono nā paipu ERW i kani, hoʻomau mau; ʻO ka wahi weld ka wela -manaʻo ʻia i ʻole e loaʻa ka martensite untempered. ʻO ka umu -paipu wiliwili ʻia i kaupalena ʻia i ka Papa A.

Hoʻopili ʻia kēlā me kēia lōʻihi paipu i:

• nānā ʻike a me ka nui no ka pololei, OD, paia a me ka ʻili
• hoʻāʻo hydrostatica i ʻoleʻae ʻia ka hoʻokolokolo hoʻopōʻino ʻole-.
• nā ho'āʻo hoʻopololei no nā huahana welded e hōʻoia i ka maikaʻi o ka weld

ʻO kēia pae mana ka mea e ʻae ʻia ai ka A53 no ka wai, ke kinoea a me ka lawelawe ʻoihana i nā hale, nā mea kanu a me nā pono hana.

Hiki ke hoʻolako ʻia nā paipu ASTM A53 -wela i hoʻopaʻa ʻia me ka hoʻoinu ʻia. E hui ka Zinc me ASTM B6, a ʻaʻole e emi ka nui o ka uhi ʻana ma lalo o nā koina liʻiliʻi i ʻōlelo ʻia ma ASTM A53. Pono e hoʻomau ʻia ka uhi ʻana, ʻaʻohe wahi kikoʻī, ʻōpala a me ka lepo kaumaha.
Paipai ʻia ʻo Galvanized A53 no nā laina waho, ka wai a me nā lawelawe ea, ka pale ahi i hōʻike ʻia, a me nā ʻenehana ʻoihana e pono ai ka hoʻomaikaʻi ʻana i ke kūpaʻa corrosion. Hiki i ka Octal Pipe ke hoʻolako i nā paipu ʻeleʻele a me nā galvanized mai ka laulā like, me ka hōʻoia ʻana o ka uhi.

• Wai, kinoea a me nā laina ea -pilikia ma nā hale, nā mea kanu a me nā ʻōnaehana kaona
• ʻO ka mahu a me ka lawelawe condensate haʻahaʻa
• Pale -ahi a me ka paipu pipi (kahi i ʻae ʻia e ASTM A53 e ka ʻōnaehana maʻamau)
• ʻO nā lālā hana a me nā mīkini e hoʻohana ana i ka paipu ma ke ʻano he kolamu, bracing a i ʻole nā ​​papa
• ʻO ka lawelawe pipeline maʻamau a me ka pahu no ka uwila/waiwai kahi i koi ʻole ʻia ai ka API 5L

• ASTM A53 ʻAno S / ʻAno E / ʻAno F
• Papa A me B
• ʻEleʻele, ʻoniʻoni a i ʻole ka wela-hoʻopaʻa galvanized
• ʻO nā ʻaoʻao maʻamau, beveled, wili a hui ʻia paha
• ʻO ka hoʻāʻo hydrostatic / NDE no kēlā me kēia lōʻihi
• EN 10204 3.1 Mill Test Certificate me nā hopena kemika a me ka mīkini
• Hoʻokuʻu aku-puʻupuʻu mākaukau me ka pale -hopena a me ka hōʻailona maopopo

FAQ

 

 

Q1: He aha ka ASTM A53 Grade A a me Grade B paipu kila i hoʻohana ʻia no?

A1: ʻO ka hana mechanical a me ke kaomi maʻamau, maʻamau no ka mahu, ka wai, ke kinoea, a me nā laina ea.

Q2: He aha ka ʻokoʻa koʻikoʻi ma waena o ASTM A53 Grade A a me Grade B?

A2: Loaʻa i ka papa B nā koi ikaika haʻahaʻa loa, no laila, makemake ʻia ia no ka hana ʻoi aʻe{1}}

Q3: He aha ka ʻokoʻa ma waena o ASTM A53 Type S a me Type E?

A3: ʻO ke ʻano S he maʻa ʻole; ʻO ke ʻano E ʻo ia ʻo ERW (uila -kuʻi kūʻē).

P4: Hiki anei i ka paipu ASTM A53 ke wela -luu galvanized?

A4: ʻAe, uhi ʻo ASTM A53 i nā paipu galvanized ʻeleʻele a me ka wela -ma muli o ke kauoha.
