Kormeeraha guud ee ASTM A106/ASME SA106 Pipe

ASTM A106/ASME SA106 waa qeexitaanka caadiga ah ee tuubada birta kaarboonka ee bilaa-la'aanta ah ee lagu dabaqo adeegyada heerkulka sare. Waxaa ka mid ah saddex darajo A, B iyo C, iyo heerka isticmaalka caadiga ah waa A106 Grade B. Waxa loo isticmaalaa in warshadaha kala duwan ma aha oo kaliya hababka dhuumaha sida saliidda iyo gaaska, biyaha, gudbinta slurry macdanta, laakiin sidoo kale loogu talagalay kuleyliyaha, dhismaha, ujeedooyinka dhismaha.

Halabuurka kiimikada ee%

● Kaarboon (C) Ugu badnaan ee darajada A 0.25, ee darajada B 0.30, darajada C 0.35
● Manganese (Mn): 0.27-0.93, 0.29-1.06
● Sulfur (S) Ugu badnaan: ≤ 0.035
● Fosfooraska (P): ≤ 0.035
● Silikoon (Si) Min: ≥0.10
● Chrome (Cr): ≤ 0.40
● Copper (Cu): ≤ 0.40
● Molybdenum (Mo): ≤ 0.15
● Nickel (Ni): ≤ 0.40
● Vanadium (V): ≤ 0.08

Fadlan ogow:
Dhimis kasta oo ah 0.01% ee curiyaha kaarboonka ugu sarreeya, korodhka 0.06% manganese ee ka sarreeya qiimaha la cayimay waa in la oggolaadaa, iyo ilaa ugu badnaan 1.35%.
Qaybaha Cr, Cu, Mo, Ni, V oo la isku daray waa in aanay ka badnayn 1%.

ASTM A106 Fasalka B Xoojinta Xoojinta iyo Xoogga Wax-soosaarka

Qaaciddada dheeraynta:
2 inji. [50mm], waa in lagu xisaabiyaa: e = 625 000 A^0.2 / U^0.9
Cutubyada inch-pound, e = 1940 A^0.2 / U^0.9
Sharaxaada e, A, iyo U, fadlan halkan ka hel. ( isla'egta ASTM A53, tuubada API 5L.)

Dhammaan cabbirrada yaryar ee lagu tijaabiyey qayb buuxda, imtixaannada safarka ee ugu yar ee elongation-ka aasaasiga ah: Fasalka A Longitudinal 35, Transverse 25; B 30, 16.5; C 30, 16.5;
Hadii la isticmaalo muunada tijaabada wareega 2 inji ee caadiga ah, qiimayaasha sare waa: Fasalka A 28, 20; B 22, 12; C 20, 12.

ASTM A106 Jadwalka Cabbirrada Dhuumaha Fasalka B

Heerku wuxuu daboolayaa cabbirka tuubooyinka ee NPS (Qaranka Heerka Toosan) min 1/8 inch ilaa 48 inch (10.3mm DN6 – 1219mm DN1200), dhanka kale wuxuu raacay dhumucda derbiga magaca ah ee caadiga ah ASME B 36.10M. Cabbirrada kale ee ka baxsan ASME B 36.10M sidoo kale waa loo oggol yahay inay isticmaalaan qeexitaankan caadiga ah.

Qalabka ceeriin

Alaabta loo isticmaalo qeexitaanka heerka ASTM A106 waa in lagu dabaqo foorarsiga, qallafsanaanta, ama hababka samaynta la midka ah. Haddii alaabta birta ah la alxanayo, habka alxanka ayaa loo malaynayaa inuu ku habboon yahay darajadan ASTM A106, oo lagu dabaqi karo jawiga heerkulka sare ee shaqada.

Meesha ay jirto heer sare ama darajo sare oo ASTM A106 tuubada birta ah ayaa loo baahan yahay, halbeeggu wuxuu leeyahay qeexid ikhtiyaari ah shuruudaha dheeriga ah, tuubooyinka isticmaalay heerkan. In ka badan, qeexitaankan dheeriga ah ayaa codsaday imtixaanka dheeriga ah, marka la rabo in la dalbado.
