Hiki ke mālama pono ʻia nā paipu inā makemake ʻia.

Inā koi ʻia e ka mea kūʻai aku, hiki ke hana ʻia ka paipu mai kahi ʻāpana kila i hoʻopaʻa ʻia a i ʻole ka pahu kila.I kēia hihia, ʻo ke ʻano o ka uhi a me ka maikaʻi o ka uhi ʻana e kūlike me nā koi o JIS G 3444, Pākuʻi A.

ʻO nā ʻano o ka uhi hiki ke hoʻohana ʻia ʻo ia ka uhi zinc wela, ka uhi zinc electrolytic, ka uhi alumini wela wela, ka zinc-5% alumini alloy coating wela, ka wela wela 55% alumini-zinc alloy coating, a i ʻole ka wela- hoʻopaʻa i ka zinc-aluminium-magnesium alloy coating.

ʻAno Hoʻopau Paipu

E palahalaha na welau o ka paipu kila.

Inā makemake ʻia ka paipu e hana ʻia i ka hopena beveled, ʻo ke kihi o ka bevel he 30-35 °, ka laulā bevel o ka ʻaoʻao paipu kila: ʻoi aku ka nui o 2.4mm.

Waiwai Mekanika o JIS G 3444

Pono nā koi maʻamau no nā hoʻokolohua mechanical e like me nā Pauku 7 a me 9 o JIS G 0404.

Eia nō naʻe, ʻo ke ʻano hoʻohālike no nā hoʻāʻo mechanical e hoʻokō i nā koi o ka papa A i ka Pauku 7.6 o JIS G 0404.

ʻO ka ikaika uʻi a me ka helu hua a i ʻole ke koʻikoʻi hōʻoia

ʻO ka ikaika tensile a me ka helu hua a i ʻole ke koʻikoʻi hōʻoia a me ka ikaika tensile ma ka weld e hoʻokō i nā waiwai i kuhikuhi ʻia ma ka Papa 3.

JIS G 3444 Papa 3

Pili ka ikaika tensile o ka weld i nā paipu welded arc.

ʻO ka ikaika o ka weld e like me ka mea e pono ai no ke kino paipu.ʻO ka ʻāpana welded pinepine ka loulou nāwaliwali i loko o ka hale, no laila ka loaʻa ʻana o ka ikaika tensile like e hōʻoia i ka hilinaʻi o ka hale welded.

Aia pū ka papa 3 i nā koi mamao no ka pale ʻana i ka Flattening a me nā koi no ke kihi piko a me ka radius piko ma ka hope hiki.

ʻO ka elongation

Hōʻike ʻia ka elongation e pili ana i ke ʻano hana o ka paipu ma ka Papa 4.

JIS G 3444 Papa 4

Eia naʻe, ke hana ʻia ka hoʻāʻo tensile ma ka ʻāpana hoʻāʻo No. 12 a i ʻole ka ʻāpana hoʻāʻo No.5 i lawe ʻia mai ka paipu ma lalo o 8 mm i ka mānoanoa o ka paia, e like ka elongation me ka Papa 5.

Kūʻē palahalaha

E kau i ka ʻāpana hoʻāʻo ma ka wela maʻamau (5 °C a 35 °C) ma waena o ʻelua mau papa pālahalaha a hoʻopaʻa i ka palahalaha a hiki i ka like a i ʻole ka liʻiliʻi o ka mamao ma waena o nā papa H i ka waiwai i kuhikuhi ʻia ma ka Papa 3, a laila e nānā i nā māwae ma ka ʻāpana hoʻāʻo.

E kau i ka welds o ke kūpale welded steel pipe a me ka butt welded steel pipe i mea e kū pono ai ka laina ma waena o ke kikowaena o ka paipu a me ka weld i ke kuhikuhi o ke kaomi.

Ho'āʻo Bend

E hoʻopōloli i ka ʻāpana hoʻāʻo a puni ka pahu ma ka wela maʻamau (5 °C a 35 °C) ma ke kihi ʻeke ʻaʻole e emi iho ma mua o ka huina liʻiliʻi liʻiliʻi i kuhikuhi ʻia ma ka Papa 3, a me ka radius o loko ʻaʻole i ʻoi aku ma mua o ka radius loko loa i kuhikuhi ʻia ma ka Papa 3, a nānā i ka ʻāpana hoʻāʻo no nā māwae.

No ka hoʻāʻo ʻana i ka paipu kila i hoʻoheheʻe ʻia a me ka paipu kila i hoʻoheheʻe ʻia, e kau i ka ʻāpana hoʻāʻo e like me ka 90 °C mai ke kūlana o waho o ka piko.

Nā ho'āʻo ʻē aʻe

E ʻae ʻia nā hoʻokolohua hydrostatic, nā hoʻokolohua non-destructive o welds, a i ʻole nā ​​​​hoʻokolohua ʻē aʻe ma mua o nā koi kūpono.

Papa Kaumaha Paipu o JIS G 3444

ʻO ke kumu hoʻohālikelike kaumaha o ka paipu kila

W=0.02466 t (Dt)

W: hui nui o ka paipu (kg/m)

t: mānoanoa pā o ka paipu (mm)

D: ke anawaena o waho o ka paipu (mm)

0.02466: huina hoololi no ka loaa ana o W

Hoʻokumu ʻia ke kumu ma ka ʻoiaʻiʻo ʻo ka nui o ke kila he 7.85 g/cm³.

Ka hoʻomanawanui ana o JIS G 3444

ʻO ke anawaena o waho

Hoʻomanawanui lōʻihi

ʻO ka hoʻomanawanui o ka lōʻihi o ka paipu kila, ʻo ka ʻae ʻole ʻole he zero, ʻaʻole koi ʻia ka hoʻomanawanui maikaʻi, ka mea kūʻai aku a me ka mea hana e hoʻoholo ma ka ʻaelike like.

Nā hiʻohiʻona

ʻO ka ʻili o loko a me waho o ka paipu kila e maʻemaʻe a ʻaʻohe kīnā ʻole e hoʻohana.

Hiki ke hoʻopili ʻia nā pale anti-corrosion e like me ka zinc-rich coatings, epoxy coatings, paint coatings, etc.

Hoailona

E hōʻailona ʻia kēlā me kēia paipu kila me ka ʻike ma lalo nei.

a)Hōʻailona o ka papa.

b) Hōʻailona no ke ʻano hana.Penei ka hoailona no ke ano hana.Hiki ke pani ʻia kahi kaha me kahi hakahaka.

1) Puka kila seamless wela wela: -SH

2) Pahu kila maʻemaʻe i hoʻopau ʻia i ke anu: -SC

3) E like me ka uila kū'ē welded kila paipu: -EG

4) Hot-hoʻopau uila kū'ē welded kila paipu: -EH

5) Ke anuu-hoʻopau uila kū'ē welded kila paipu: -EC

6) Puka-welded kila paipu -B

7) Aunoa arc welded kila paipu -A

c) Anana.E kaha ʻia ke anawaena o waho a me ka mānoanoa o ka pā.

d) Ka inoa o ka mea hana a i ʻole ka pōkole.

Ke paʻakikī ke kaha ʻana i ka paipu no ka liʻiliʻi o ke anawaena o waho a i ʻole ke noi ʻia e ka mea kūʻai mai, hiki ke hoʻopaʻa ʻia i kēlā me kēia pūpū o nā paipu ma ke ʻano kūpono.

Nā hana e like me ka hoʻohana ʻana i nā lepili, etc.

JIS G 3444 Noi

Hoʻohana ʻia lākou no ka ʻenekinia kīwila a me ka hoʻolālā e like me nā hale kiaʻi kila, nā scaffoldings, nā puʻu wāwae, nā puʻu kumu, a me nā puʻu no ka hoʻopau ʻana i ka ʻāina.

Nā Kūlana Pili

JIS G 3452: Hōʻike i nā paipu kila kalapona no nā kumu maʻamau (ʻokoʻa mai nā kumu hoʻolālā a ʻoi aku ka nānā ʻana i ka lawe ʻana i nā wai a i ʻole ke kinoea).

JIS G 3454: Hōʻike i nā kūlana no nā paipu kila kalapona no ka paipu kaomi.

ASTM A500: uhi i ke anu-hana welded a me ka seamless kalapona kila structural paipu a ua like me JIS G 3444 i kekahi o kona mau koi.

EN 10219: Uhi i na pauku wiliwili wiliwiliia no na hana hana, e like me ka poepoe, huinaha, a me ka huinahalike.

ʻO kā mākou pono

Mai kona hoʻokumu ʻana i ka makahiki 2014, ua lilo ʻo Botop Steel i mea hoʻolako alakaʻi i ka paipu kila carbon ma Northern China, i ʻike ʻia no ka lawelawe maikaʻi loa, nā huahana kiʻekiʻe, a me nā hoʻonā piha.

Hāʻawi ka hui i nā ʻano paipu kila kalapona a me nā huahana pili, me ka seamless, ERW, LSAW, a me ka paipu kila SSAW, a me ka laina piha o nā paipu paipu a me nā flanges.

ʻO kāna mau huahana kūikawā pū kekahi me nā mea kila kiʻekiʻe a me nā austenitic stainless steel, i hana ʻia e hoʻokō i nā koi o nā papahana pipeline like ʻole.
