Chitoliro cha ASTM A106/ASME SA106 chowonjezera

ASTM A106/ASME SA106 ndiye muyezo wokhazikika wa chitoliro chachitsulo cha kaboni chopanda msoko chomwe chimagwiritsidwa ntchito pa ntchito zotentha kwambiri. Chili ndi magiredi atatu A, B ndi C, ndipo giredi yogwiritsidwa ntchito kwambiri ndi A106 Giredi B. Imagwiritsidwa ntchito m'mafakitale osiyanasiyana osati kokha pamakina a mapaipi monga mafuta ndi gasi, madzi, kutumiza kwa slurry ya mchere, komanso pa boiler, zomangamanga, ndi zomangamanga.

Kapangidwe ka mankhwala mu %

● Mpweya Wopanda Kaboni (C) Wapamwamba pa Giredi A 0.25, wa Giredi B 0.30, wa Giredi C 0.35
● Manganese (Mn): 0.27-0.93, 0.29-1.06
● Sulfure (S) Kuchuluka Kwambiri: ≤ 0.035
● Phosphorus (P): ≤ 0.035
● Silicon (Si) Min : ≥0.10
● Chrome (Cr): ≤ 0.40
● Mkuwa (Cu): ≤ 0.40
● Molybdenum (Mo): ≤ 0.15
● Nikeli (Ni): ≤ 0.40
● Vanadium (V): ≤ 0.08

Chonde dziwani:
Pa kuchepetsa kulikonse kwa 0.01% kwa chinthu chachikulu cha kaboni, kuwonjezeka kwa 0.06% ya manganese pamwamba pa mtengo womwe watchulidwa kudzaloledwa, ndipo mpaka 1.35%.
Zinthu Cr, Cu, Mo, Ni, V zophatikizidwa siziyenera kupitirira 1%.

Mphamvu Yokoka ndi Kutulutsa kwa ASTM A106 Giredi B

Fomula yotalikira:
Mu 2 in. [50mm], iyenera kuwerengedwa ndi: e = 625 000 A^0.2 / U^0.9
Pa mayunitsi a inchi-paundi, e = 1940 A^0.2 / U^0.9
Mafotokozedwe a e, A, ndi U, chonde pezani apa. (Chiyerekezo chomwecho ndi ASTM A53, API 5L chitoliro.)
Mphamvu Yokoka, mphindi, psi [MPa] Giredi A 48,000 [330], Giredi B 60,000 [415], Giredi C 70,000 [485]
Mphamvu yocheperako ya zokolola pa psi [MPa] Giredi A 30,000 [205], B 35,000 [240], C 40,000 [275]
Kutalika kwa mainchesi awiri (50mm), peresenti yocheperako %
Pa kukula konse kakang'ono komwe kwayesedwa mu gawo lonse, mayeso oyambira otalikirapo opitilira: Giredi A Longitudinal 35, Transverse 25; B 30, 16.5; C 30, 16.5;
Ngati chitsanzo choyesera chozungulira cha mainchesi awiri chikugwiritsidwa ntchito, mitengo yomwe ili pamwambapa ndi iyi: Giredi A 28, 20; B 22, 12; C 20, 12.

Ndandanda ya Miyeso ya Chitoliro cha ASTM A106 Giredi B

Muyezowu umakhudza kukula kwa mapaipi mu NPS (National Standard Straight) kuyambira 1/8 inchi mpaka 48 inchi (10.3mm DN6 - 1219mm DN1200), pomwe uku kunali makulidwe a khoma la ASME B 36.10M. Pa makulidwe ena a ASME B 36.10M, muyezo uwu umaloledwanso kugwiritsidwa ntchito.

Zida zogwiritsira ntchito

Zipangizo zomwe zimagwiritsidwa ntchito pa muyezo wa ASTM A106 ziyenera kugwiritsidwa ntchito popindika, kupotoza, kapena njira zina zofananira zopangira. Ngati chitsulocho chikuyenera kuwotcherera, njira yowotcherera iyenera kukhala yoyenera mtundu uwu wa ASTM A106, ndipo iyenera kugwiritsidwa ntchito pamalo ogwirira ntchito otentha kwambiri.

Ngati pali chitoliro chachitsulo cha ASTM A106 chapamwamba kapena chapamwamba, muyezowo uli ndi zofunikira zina zowonjezera, za mapaipi omwe adagwiritsa ntchito muyezowu. Kuonjezera apo, zofunikira izi zowonjezera zidapempha mayeso owonjezera, nthawi yomwe oda iyenera kuyikidwa.
