Pulea o le Paipa ASTM A106/ASME SA106

O le ASTM A106/ASME SA106 o le fa'amatalaga masani lea mo paipa u'amea kaponi e leai ni so'oga e fa'aaogaina mo auaunaga i le vevela maualuga. E aofia ai vasega e tolu A, B ma le C, ma o le vasega e masani ona fa'aaogaina o le A106 Vasega B. E fa'aaogaina i pisinisi eseese e le gata mo faiga o paipa e pei o le suau'u ma le kesi, vai, felauaiga o minerale, ae fa'apea fo'i mo paila, fausiaina, ma fa'amoemoega fa'avae.

Fa'asologa o vaila'au i le %

● Kaponi (C) Maualuga Mo le Vasega A 0.25, Mo le Vasega B 0.30, Vasega C 0.35
● Manganese (Mn): 0.27-0.93, 0.29-1.06
● Sulfur (S) Maualuga: ≤ 0.035
● Fosforus (P) : ≤ 0.035
● Silicon (Si) Min : ≥0.10
● Chrome (Cr): ≤ 0.40
● Kopa (Cu): ≤ 0.40
● Molybdenum (Mo): ≤ 0.15
● Nikel (Ni): ≤ 0.40
● Vanadium (V): ≤ 0.08

Fa'amolemole ia matau:
Mo fa'aitiitiga ta'itasi e 0.01% mo le maualuga o le elemene kaponi, e fa'atagaina se fa'aopoopoga e 0.06% manganese i luga atu o le tau fa'atulagaina, ma e o'o atu i le maualuga e 1.35%.
E lē tatau ona sili atu le aofa'i o elemene Cr, Cu, Mo, Ni, V pe a tu'ufa'atasi i le 1%.

ASTM A106 Vasega B Malosiaga o le Fa'ase'e ma le Malosiaga o le Fa'ase'e

Fua fa'atatau o le fa'aloaloa:
I le 2 inisi [50mm], e tatau ona fuafuaina e ala i le: e = 625 000 A^0.2 / U^0.9
Mo Iunite inisi-pauna, e = 1940 A^0.2 / U^0.9
Fa'amatalaga o le e, A, ma le U, fa'amolemole maua iinei. (E tutusa le fua fa'atatau ma le ASTM A53, paipa API 5L.)
Malosiaga o le Tete'e, min, psi [MPa] Vasega A 48,000 [330], Vasega B 60,000 [415], Vasega C 70,000 [485]
Malosiaga Maualalo i le psi [MPa] Vasega A 30,000 [205], B 35,000 [240], C 40,000 [275]

Mo lapopo'a laiti uma na fa'ata'ita'iina i le vaega atoa, o su'ega fa'avae o le fa'aloaloa la'ititi i le fa'alava: Vasega A Longitudinal 35, Transverse 25; B 30, 16.5; C 30, 16.5;
Afai e fa'aaogaina le fa'ata'ita'iga masani o le fua fa'ata'ita'i e 2 inisi le umi, o tau o lo'o i luga e: Vasega A 28, 20; B 22, 12; C 20, 12.

Fa'asologa o Fua o Paipa ASTM A106 Vasega B

O le tulaga faatonuina e aofia ai le tele o paipa i le NPS (National Standard Straight) mai le 1/8 inisi i le 48 inisi (10.3mm DN6 – 1219mm DN1200), ae o loʻo tausisia le mafiafia masani o le puipui o le tulaga faatonuina ASME B 36.10M. Mo isi lapopoa i fafo atu o le ASME B 36.10M e faʻatagaina foʻi ona faʻaogaina lenei faʻamatalaga faʻatonuina.

Mea mata

O meafaitino e faʻaaogaina mo le faʻamatalaga masani a le ASTM A106 e tatau ona faʻaaogaina mo le punou, flanging, poʻo ni faiga faʻapena. Afai o le a faʻapipiʻiina le uʻamea, e tatau ona talafeagai le faiga faʻapipiʻi mo lenei vasega o le ASTM A106, ma e talafeagai mo le siosiomaga faigaluega e maualuga le vevela.

Afai e manaʻomia se paipa uʻamea sili atu pe maualuga atu, o le tulaga faʻatonuina e iai se faʻamatalaga e filifili pe faʻapefea mo manaʻoga faaopoopo, mo paipa na faʻaaogaina lenei tulaga faʻatonuina. E le gata i lea, o nei faʻamatalaga faaopoopo e manaʻomia ai se suega faaopoopo, pe a tuʻuina le poloaiga.
