I ka wā e pili ana i nā ʻōnaehana paipu ʻoihana, ʻo nā paipu A53 Grade B kahi koho kaulana ma muli o ko lākou versatility a me ka hilinaʻi. ʻO kēia mau paipu, i kapa pinepine ʻia a53 gr.b paipu, hoʻohana nui ʻia i nā noi like ʻole, me ka hoʻouna ʻana i ka wai a me ke kinoea, ke kūkulu ʻana, a me nā kumu ʻenekinia maʻamau. He mea koʻikoʻi ka hoʻomaopopo ʻana i nā ana, ka nui maʻamau, a me ka hoʻomanawanui ʻana o kēia mau paipu no nā ʻenekinia, nā mea hana aelike, a me nā luna o ka papahana e hōʻoia i ke koho kūpono a me ka hoʻonohonoho ʻana. Ma kēia alakaʻi holoʻokoʻa, e ʻimi mākou i nā kikoʻī o nā ana paipu A53 Grade B, e ʻimi ana i nā ana maʻamau, nā ʻae ʻana, a me nā pae nui maʻamau no nā ʻano like ʻole a welded.

Nā Ana maʻamau a me ka mānoanoa o ka pā o nā paipu A53 Grade B
Hana ʻia nā paipu A53 Grade B e like me ka maʻamau ASTM A53, e hōʻike ana i nā koi no ka seamless a welded carbon steel pipe. Loaʻa kēia mau paipu ma nā ʻano nui like ʻole e hoʻokō i nā pono papahana like ʻole. ʻO nā ana maʻamau o a53 gr.b paipu hōʻike maʻamau ʻia ma ke ʻano o ka nui o ka paipu nominal (NPS), ke anawaena o waho (OD), a me ka mānoanoa o ka pā.
ʻO ka nui o ka paipu nominal he mea hoʻohālike ʻole e like me ke anawaena o loko o ka paipu. Eia naʻe, he mea nui e hoʻomaopopo he ʻokoʻa paha ke anawaena maoli i ka nui nominal. ʻO ke anawaena o waho o nā paipu A53 Grade B mau no ka nui i hāʻawi ʻia, ʻoiai hiki ke ʻokoʻa ka mānoanoa o ka pā ma muli o ka papa kuhikuhi a i ʻole ka papa kaumaha o ka paipu.
He mea koʻikoʻi ka mānoanoa o ka pā i ka hoʻoholo ʻana i ka mana o ka paipu a me ka ikaika holoʻokoʻa. Loaʻa nā paipu A53 Grade B i nā papa manawa like ʻole, me ka Hōʻike 40 a me ka Hōʻike 80 ka mea maʻamau. ʻO ka helu hoʻonohonoho e pili ana i kahi ʻōnaehana maʻamau e wehewehe i ka pilina ma waena o ka nui o ka paipu, ke anawaena o waho, a me ka mānoanoa o ka pā.
No ka laʻana, he paipu 4-inihi NPS A53 Grade B me ka Hōʻike 40 he 4.5 ʻīniha ke anawaena o waho a he 0.237 iniha ka mānoanoa o ka pā. ʻO ka paipu NPS 4-inihi like ma ka Hōʻike 80 e mālama i ka 4.5-inihi waho anawaena akā he pā mānoanoa ma 0.337 iniha.
Pono e hoʻomaopopo ʻia aia nā paipu a53 gr.b i nā papa hana ʻē aʻe a me nā papa kaumaha, e like me Standard (STD), Extra Strong (XS), a me Double Extra Strong (XXS), kēlā me kēia hāʻawi ʻana i nā mānoanoa pā like ʻole e kūpono i nā koi noi kikoʻī.
ʻO ka hoʻomanawanui a me nā koi nui ma lalo o ASTM A53
Hoʻonohonoho ka maʻamau ASTM A53 i nā ʻae a me nā koi dimensional no nā paipu A53 Grade B e hōʻoia i ka kūlike a me ka hilinaʻi i ka hana. Hoʻopili kēia mau ʻae ʻana i nā ʻano like ʻole o ka nui o ka paipu, me ke anawaena o waho, ka mānoanoa o ka paia, a me ka lōʻihi.
1.Outside anawaena tolerances:
no ka mea, a53 gr.b paipu me ka NPS 1-1/2 a me ka liʻiliʻi, ʻo ka hoʻomanawanui ma ke anawaena o waho he ± 0.015 iniha. No nā paipu NPS 2 a ʻoi aku ka nui, ʻo ka hoʻomanawanui ʻo ± 1% o ke anawaena waho i ʻōlelo ʻia. ʻO kēia haʻawina e hōʻoia e hiki ke hoʻokomo pono i nā paipu me nā mea hoʻohui maʻamau a me nā mea pono.
2. Wall Thickness Tolerances:
ʻO ka mānoanoa o ka pā o nā paipu A53 Grade B e pili ana i nā ʻae a ma lalo o ka hoʻomanawanui. No nā paipu lauwili ʻole, ʻaʻole ʻoi aku ka mānoanoa o ka pā ma kēlā me kēia wahi ma mua o 12.5% ma lalo o ka mānoanoa o ka paia i kuhikuhi ʻia. No nā paipu welded, ua hoʻonohonoho ʻia kēia ma lalo o ka hoʻomanawanui ma 8% o ka mānoanoa o ka pā. ʻAʻole kaupalena ʻia nā ʻae ʻana ke ʻole ka palena kiʻekiʻe ma ke kauoha kūʻai.
3. Length tolerances:
Hoʻolako pinepine ʻia nā paipu A53 Grade B i nā lōʻihi like ʻole, ma waena o 16 a me 22 kapuaʻi. Ke koi ʻia nā lōʻihi kikoʻī, ʻae ka maʻamau i ka hoʻomanawanui o ± 1/2 iniha no ka lōʻihi a hiki i 30 kapuaʻi, a me ± 3/4 iniha no ka lōʻihi ma luna o 30 kapuaʻi.
4. Pololei:
Hōʻike pū ka maʻamau ASTM A53 i nā koi no ka pololei o ka paipu. No nā paipu 1-1/4 iniha NPS a ʻoi aku ka nui, ʻaʻole ʻoi aku ka nui o ka haʻalele ʻana mai kahi laina pololei ma mua o 0.030 mau ʻīniha ka nui o nā kapuaʻi o ka lōʻihi i puʻunaue ʻia e 22.
He mea koʻikoʻi kēia mau ʻae ʻana no ka hōʻoia ʻana e hoʻokō nā paipu a53 gr.b i nā kūlana kūpono kūpono a hiki ke hilinaʻi ʻia i nā noi like ʻole. ʻO ka mālama ʻana i kēia mau koi dimensional e kōkua i ka mālama ʻana i ka pono o nā ʻōnaehana paipu a hōʻoia i ke kūpono kūpono a me ka hana i nā hui.
Kaulana maʻamau no nā paipu A53 Grade B i hoʻopaʻa ʻole ʻia a welded
Loaʻa nā paipu A53 Grade B i nā ʻano nui e hoʻokō i nā koi o ka papahana. ʻOkoʻa iki nā pae nui ma waena o nā paipu wili ʻole a me nā paipu welded, me kēlā me kēia ʻano e hāʻawi i nā pono kūʻokoʻa no nā noi kikoʻī.
1. ʻAʻohe A53 Papa B Paipu:
Hana ʻia nā paipu seamless me ka ʻole o kahi wili wili, e hāʻawi ana i ka ikaika a me ka hilinaʻi no nā noi kiʻekiʻe. Nā laula nui maʻamau no ka maʻemaʻe a53 gr.b paipu puke:
- NPS 1/8 a i NPS 26
- Ka Anawaena waho: 0.405 iniha a 30 iniha
- Mānoanoa Pā: Hōʻike 10 a i ka Hōʻike 160
2.Welded A53 Grade B paipu:
Hoʻokumu ʻia nā paipu welded e ka ʻōwili ʻana i ke kila pālahalaha a me ka wili ʻana i ka hili ʻana, e hāʻawi ana i nā hopena kūpono no nā noi he nui. ʻO nā pae nui maʻamau no nā paipu a53 gr.b i wiliwili ʻia:
- NPS 1/2 a i NPS 24
- Ka Anawaena waho: 0.840 iniha a 24 iniha
- Mānoanoa Pā: Hōʻike 10 a i ka Hōʻike 80
He mea nui e hoʻomaopopo ʻaʻole i loaʻa nā hui like ʻole a me ka nui no nā paipu ʻole a welded. Hiki ke ʻokoʻa ka loaʻa ʻana o nā nui kikoʻī a me ka mānoanoa o ka pā ma muli o ka mea hana a me ka hiki ke hana.
3. Ke koho ʻana i nā paipu a53 gr.b no kahi papahana, e noʻonoʻo i nā mea e like me:
- ʻO ke kaomi hana a me ka mahana
- Lawe ʻia ka wai a i ʻole ke kinoea
- Nā kūlana o ke kaiapuni
- ʻO keʻano hoʻonohonoho
- Noʻonoʻo kumukūʻai
Ma ka hoʻomaopopo ʻana i nā ana maʻamau, ka ʻae ʻana, a me nā pae nui maʻamau o nā paipu A53 Grade B, hiki i nā ʻenekinia a me nā luna papahana ke hoʻoholo i ka ʻike e hōʻoia i ka holomua a me ka lōʻihi o kā lākou ʻōnaehana paipu.
Hoʻokaʻaʻike iā Longma
He kuleana koʻikoʻi nā paipu A53 Grade B i nā ʻoihana like ʻole, e hāʻawi ana i nā hopena hilinaʻi a maʻalahi no ka lawe ʻana i ka wai a me ke kinoea. ʻO ka hoʻomaopopo ʻana i nā ana, ka hoʻomanawanui, a me nā pae nui o kēia mau paipu he mea nui ia no ke koho kūpono a me ka hoʻonohonoho ʻana. Ke koho nei no ka seamless a welded paha a53 gr.b paipu, he mea nui e noʻonoʻo i nā koi kikoʻī o kāu papahana a kūkākūkā me nā mea hana akamai e hōʻoia i ka mea kūpono loa no kāu mau pono.
No nā paipu A53 Grade B kiʻekiʻe a me ke alakaʻi akamai i ke koho paipu, mai nānā ʻoe ma mua o Longma Group. E like me kekahi o Kina e alakai ERW / LSAW kila paipu Manufacturers mai 2003, Longma Group specializes i ka hana ana i ka nui-anawaena, manoanoa-pā, elua-aoao, sub-arc-seam wili kila paipu, me LSAW (Longitudinal Submerged Arc Welded) a me ERW paipu kila. Me ka puka makahiki ma mua o 1,000,000 tons ma ka hopena o 2023, loaʻa iā Longma Group ka ʻike a me ka hiki ke hoʻokō i kāu mau pono paipu. No ka ʻike hou aku a i ʻole e kūkākūkā i kāu mau koi papahana, e ʻoluʻolu e kelepona mai iā mākou ma info@longma-group.com.
