Paipu kila ASTM A53 humuhumuua hoʻokaʻawale ʻia ʻo ia ʻo A53 Type S a he paipu kila humuhumu ʻole ia.
Ua māhele ʻia i ʻelua mau papa, Papa A a me Papa B, a kūpono ia no nā noi mīkini a me ke kaomi, a me ka hoʻohana maʻamau no ka mahu, ka wai, ke kinoea, a me ka ea. He paipu kila kalapona kēia paipu kila i kūpono no ka hoʻoheheʻe ʻana a me nā hana hana e pili ana i ka wili ʻana, ke kulou ʻana, a me nā pilina flange.

I ka hana maoli, ʻo ka Papa Kuhikuhi 40 a me ka Papa Kuhikuhi 80 nā ʻano mānoanoa o ka paia paipu i hoʻohana nui ʻia. No ka ʻike hou aku, e ʻoluʻolu e nānā i kaPapa kuhikuhi PDFfaila a mākou e hāʻawi nei.
Mai kona hoʻokumu ʻia ʻana i ka makahiki 2014,Botop Steelua lilo i mea hoʻolako alakaʻi o ka paipu kila kalapona ma Northern Kina, i ʻike ʻia no ka lawelawe maikaʻi loa, nā huahana kiʻekiʻe, a me nā hoʻonā piha.
Hāʻawi ka ʻoihana i nā ʻano paipu kila kalapona like ʻole a me nā huahana pili, me ka paipu kila seamless, ERW, LSAW, a me SSAW, a me kahi papa inoa piha o nā mea hoʻopili paipu a me nā flanges. Hoʻokomo pū kāna mau huahana kūikawā i nā metala kiʻekiʻe a me nā kila kila austenitic, i hana ʻia e hoʻokō i nā koi o nā papahana paipu like ʻole.
Hiki ke hoʻohuihui ʻia a wili ʻia paha nā paipu kila ASTM A53.
ʻO ke ʻano hana hana seamless (ʻAno S) he hana wela ia o ke kila, a inā pono, hoʻopau anu i ka huahana tubular i hana wela ʻia e hoʻokō ai i ke ʻano, nā ana, a me nā waiwai i makemake ʻia.
Ma ke kūlana ASTM A53, nā koi hoʻohuihui kemika no ke ʻAno S a meʻAno EUa like nā paipu kila, ʻoiai he ʻokoʻa nā koi hoʻohui kemika no ke ʻAno F.
ANā mea ʻelimaCu,Ni,Cr,Mo, a meVʻaʻole pono e ʻoi aku ma mua o 1.00% i ka hui pū ʻana.
BNo kēlā me kēia hōʻemi ʻana o 0.01% ma lalo o ka palena kiʻekiʻe o ke kalapona i kuhikuhi ʻia, e ʻae ʻia ka hoʻonui ʻana o 0.06% o ka manganese ma luna o ka palena kiʻekiʻe i kuhikuhi ʻia a hiki i ka palena kiʻekiʻe o 1.35%.
CNo kēlā me kēia hōʻemi ʻana o 0.01% ma lalo o ka palena kiʻekiʻe o ke kalapona i kuhikuhi ʻia, e ʻae ʻia ka hoʻonui ʻana o 0.06% o ka manganese ma luna o ka palena kiʻekiʻe i kuhikuhi ʻia a hiki i ka palena kiʻekiʻe o 1.65%.

Hoʻāʻo Kūlou
No DN ≤ 50 [NPS ≤ 2], pono e hiki ke pelu anu ʻia kahi paipu lawa ma o 90° a puni kahi mandrel cylindrical, ʻo ke anawaena he ʻumikūmālua manawa o ke anawaena waho i kuhikuhi ʻia o ka paipu, me ka ʻole o ka ulu ʻana o nā māwae ma kekahi ʻāpana.
Pālua-ikaika loa(XXS) ʻaʻole pono e hoʻāʻo ʻia ke kūlou ʻana o ka paipu ma luna o DN 32 [NPS 1 1/4].
Hoʻāʻo Hoʻopālahalaha
ʻAʻole pono e hoʻāʻo ʻia ka hoʻopālahalaha ʻana o nā paipu kila humuhumu ʻole.
Inā koi ʻia e ka ʻaelike, hiki ke hoʻokō ʻia ka hoʻokolohua e like me ke kaʻina hana ma S1.
Pono nā paipu kila humuhumu a pau e mālama i kahi waiwai kaomi wai me ka ʻole o ka liki ʻana no ka liʻiliʻi he 5 kekona.
Hiki ke loaʻa ke kaomi hoʻāʻo no nā paipu kila ʻaoʻao maʻamau ma ka Papa X2.2.
Hiki ke loaʻa nā kaomi hoʻāʻo no nā paipu kila i wili ʻia a me nā paipu kila i hoʻopili ʻia ma ka Papa X2.3.
Hiki ke hoʻohana ʻia ma ke ʻano he koho ʻē aʻe i ka hoʻāʻo hydrostatic.
E hoʻāʻo ʻia ka lōʻihi holoʻokoʻa o kēlā me kēia paipu humuhumu ʻole e like me kaE213, E309, a i ʻoleE570.
I ke kūʻai ʻana iā ASTM A53, pono e hoʻokō ka hoʻomanawanui ʻana i ka nui o ka paipu kila i nā koi aʻe.

| ʻoi aku ka māmā ma mua o ke kaumaha ikaika loa (XS) （nā lōʻihi pālua-kaulike） | ≥6.71m (ʻO ka lōʻihi awelika haʻahaʻa loa he 10.67m) |
Hoʻākāka ke kūlana ASTM A53 i nā koi no ke kūlana paipu ʻeleʻele a me ka uhi galvanized wela o nā paipu kila.
Paipu ʻEleʻele
ʻO ka paipu ʻeleʻele e pili ana i ke kūlana o ka paipu kila me ka ʻole o ka mālama ʻana i ka ʻili.
Hoʻohana pinepine ʻia nā paipu ʻeleʻele ma nā wahi i pōkole ai ka manawa mālama, maloʻo ke kaiapuni a ʻaʻole e palaho, a ʻoi aku ka haʻahaʻa o ke kumukūʻai no ka mea ʻaʻohe uhi.
Uhi Galvanized Wela-dip
ʻO nā paipu galvanized, i ʻike ʻia hoʻi he mau paipu keʻokeʻo, hoʻohana pinepine ʻia i nā wahi humid a corrosive paha.
Hiki i ka zinc i loko o ka uhi zinc ke lilo i kekahi papa o ka zinc ma ASTM B6.
ʻAʻole pono ka paipu galvanized mai nā wahi i uhi ʻole ʻia, nā pehu, nā waihona flux, a me nā mea i hoʻokomo ʻia i loko o ka lepo. ʻAʻole ʻae ʻia nā puʻupuʻu, nā mea i hoʻolei ʻia, nā globules, a i ʻole nā waihona nui o ka zinc e hoʻopilikia i ka hoʻohana ʻia ʻana o ka mea i manaʻo ʻia.
ʻAʻole emi ka nui o ka zinc ma lalo o 0.55 kg/m² [1.8 oz/ft²].
Nā Uhi ʻē aʻe
Ma waho aʻe o ka paipu ʻeleʻele a me ka uhi galvanized, nā ʻano uhi maʻamau e komo pū mepena, 3LPE, FBE, a pēlā aku. Hiki ke koho ʻia ke ʻano uhi kūpono e like me nā koi kikoʻī o ke kaiapuni hana.
ʻO ka hāʻawi ʻana i ka ʻike ma lalo nei e ʻoi aku ka maikaʻi a me ka pololei o kāu kaʻina kūʻai.
