Aʻo faʻaleleia atili le manaʻoga mo mea faʻapipiʻi i totonu o fale gaosi oloa, o loʻo faʻaauau pea ona tulaʻi le lauiloa o paipa faʻafefe ma paipa uelo. O lenei tusiga o le a auiliili auiliili mai le vaaiga o le tuufaatasiga o meafaitino, tulaga lelei autu, auala eseese ma fanua talafeagai, ma tuufaatasia upu autu suʻesuʻe vevela "filifiliga o mea tau paipa maualuga" ma "mea faufale taugofie" e maua ai faʻamatalaga mo le faʻatauina o inisinia.
1. Fausia meafaitino
Pipa e leai se su'ega
Mea autu: uamea sili ona lelei (e pei o le 20 sila, 35 sila), uamea uamea (e pei o le 16Mn, 40Cr), uamea uamea (304/316L) ma le uamea (20g)
Fa'aaliga: leai ni uelo, tu'iga tutusa, talafeagai mo le maualuga o le vevela ma le maualuga o le mamafa o fa'aaliga.
Paipa uelo
Mea autu: uʻamea maualalo (Q235), uʻamea uʻamea maualalo (L290, L360), uʻamea uʻamea ma uʻamea uʻamea
Fa'aaliga: faia e ala i le ueloina o ipu uamea, tau maualalo ma fa'amatalaga fetu'una'i.
2. Fa'atusatusaga o fa'amanuiaga autu
Vasega Fa'alelei lelei paipa u'elo
Malosi Malosi maualuga atoa, faʻamalosi malosi e sili atu nai lo le 415MPa16 O le malosi o le uelo e laʻititi laʻititi, ae mafai ona ausia manaʻoga maualalo.
Fa'agasologa Leai se uelo, aloese mai le leakage risk15 maualuga gaosiga lelei, 30% -50% tau maualalo
Foliga Fa'alelei luga, leai ni fa'ailoga fa'agaioiga3 O lo'o iai uelo, e mana'omia le fa'aleleia o foliga6
Fa'aoga Suau'u ma kesi maualuga, malosi faaniukilia, masini sa'o 5 Fau fale, inisinia fa'apitonu'u, vai fa'ato'aga.
3. 4 laʻasaga e iloagofie ai paipa le lelei mai paipa uelo
Mataʻituina le uelo: faʻailoga laina laina e mafai ona vaʻaia i totonu ma fafo puipui o le paipa uelo, ma o le paipa e leai ni suʻiga
Malosi o le su'ega: o paipa e leai se mea e mafai ona tatalia su'ega maualuga o le vai (pei o luga ole 30MPa)
Iloilo le vaega fa'alava: o le paipa e leai se fa'aoga o lo'o i ai se vaega fa'alava toniga, ma o le paipa uelo e mafai ona i ai sina eseesega mafiafia ona o le uelo.
Siaki le tusi faamaonia: e manaʻomia e paipa e leai ni mea e maua ai lipoti e iloa ai mea leaga, ma o paipa uelo e taulaʻi ile faʻamaoniaga lelei.
4. Fa'ata'ita'iga fa'atatau o lo'o fautuaina
Paipa e leai ni su'ega:
Suau'u ma kesi fa'alenatura: paipa fa'asalalau maualuga (X60/X70 grade sila)
Malosiaga ma le malosi: paipa fa'avevela, faiga fa'amalo faaniukilia
Fa'ato'aga maualuga: paipa va'alele va'alele, ta'avale ta'avale
Paipa u'elo:
Inisinia faufale: fa'avaa fausaga u'amea, fata
Soifuaga fa'apitonu'u: sapalai vai ma alavai, faiga HVAC
Fa'ato'aga ma alamanuia: paipa fa'asusu, fata teu oloa
V. Jindalai Steel: Fofo paipa e tasi e taofi
I le tali atu i suʻesuʻega vevela talu ai nei o le "spot supply" ma "paipa taugofie", o le Jindalai Steel Company ua avea ma filifiliga muamua a le alamanuia ma tulaga lelei nei:
Fa'ato'a vaega: ufiufi uamea kaponi, uamea u'amea, u'amea u'amea paipa fa'afefeteina ma paipa uelo, lagolagoina fa'apitoa le fa'avasegaina lapopo'a.
Tau fa'amanuiaga: fa'atupu tele-fua fa'aitiitia tau, ma o le tau iunite o paipa uelo e 10% maualalo nai lo le maketi.
Faʻamautinoaga lelei: tuʻuina atu lipoti o asiasiga a isi vaega (e pei o le SGS, BV), faʻatasi ma GB / T 3091, GB / T 9711 ma isi tulaga faʻale-atunuu.
Tali vave: 5,000 tone o fa'amaumauga tumau
Fa'ai'uga
Pe o seamless paipa i lalo-omiga faʻataʻitaʻiga poʻo le tamaoaiga ma lelei paipa uelo, filifilia o mea saʻo e mafai ona faʻateleina le manuia o le poloketi. Jindalai Steel, faʻatasi ai ma tekinolosi e pei o le lagolago ma le auʻaunaga e avea ma autu, e tuʻuina atu ai i tagata faʻatau i le lalolagi atoa ni vaifofo paipa taugofie e fesoasoani ai i galuega faʻatautaia lelei!
