Chitoliro cha Chitsulo cha API 5L X52 PSL2 Sour Service LSAW: Mphamvu Zopangira & Zofotokozera Zamalonda

Kufotokozera Kwachidule:

Womic Steel imapereka chitoliro chachitsulo cha API 5L X52 PSL2 cha LSAW chapamwamba kwambiri chotumizira mafuta ndi gasi m'malo okhala ndi H₂S (owawa). X52 PSL2 yokhala ndi satifiketi ya ntchito yowawa imapereka mphamvu yocheperako ya 360 MPa (52,200 psi) kuphatikiza ndi malire olimba (≤ 90 HRB, nthawi zambiri ≤ 85 HRB), low carbon equivalent (CEV ≤ 0.40%), komanso kukana kotsimikizika ku hydrogen induced cracking (HIC) ndi sulfide stress cracking (SSC). Njira ya LSAW imaphatikizapo njira zowotcherera za JCOE, UOE, ndi rolled plate, ndi njira yofunikira yochiritsira kutentha pambuyo pa weld (PWHT) pamapaipi onse ogwirira ntchito yowawa mosasamala kanthu za makulidwe a khoma. M'mimba mwake wakunja kuyambira 219mm mpaka 1,600mm (8″ – 63″), makulidwe a khoma kuyambira 6.0mm mpaka 60mm, kutalika mpaka 24m. Chiphaso cha mphero chokhala ndi EN 10204 3.2, mayeso a ultrasonic 100% okhala ndi TOFD, mayeso a hydro, malekezero opindika, ndi phukusi lonse la zikalata zautumiki wowawasa (HIC, SSC, ma hardness traverses). Choyenera mapaipi osonkhanitsa mpweya wowawasa, mizere yamafuta yokhala ndi H₂S, mizere yamadzi owawasa yoyeretsera, ndi ntchito ya acidic yakunja kwa dziko.

Kukula kwa Chitoliro cha Chitsulo cha LSAW:Chipinda chakunja: 219mm – 1,600mm (8″ – 63″), Kukhuthala kwa Khoma: 6.0mm – 60.0mm (JCOE/UOE max 50.8mm, rolled plate max 60mm), Kutalika: 6m – 18m muyezo, kutalika kwapadera mpaka 24m

Chitoliro cha Chitsulo cha LSAW Chokhazikika & Chachikulu:API 5L X52 PSL2 yokhala ndi zofunikira zina zautumiki wowawasa malinga ndi NACE MR0175/ISO 15156; HIC pa NACE TM0284; SSC pa NACE TM0177

Kugwiritsa Ntchito Chitoliro cha Chitsulo cha LSAW:Mapaipi osonkhanitsa gasi wachilengedwe wowawasa (H₂S mpaka 50 ppm), njira zoyendera mafuta osakonzedwa okhala ndi H₂S, njira zoyeretsera madzi owawasa, njira zoyeretsera madzi owawasa m'mphepete mwa nyanja, njira zokwezera gasi m'zitsime zowawasa, njira zoyeretsera mpweya wa amine, njira zobayira mpweya wa asidi, njira zobwezeretsera mpweya wa sulfure

Womic Steel imapereka mitengo yapamwamba komanso yopikisana ya API 5L X52 PSL2 sour service LSAW steel pipe, HIC tested line pipe, SSC resistant payipi, NACE compliant LSAW payipi. Chiphaso cha Mill EN 10204 3.2, hydro test, UT/TOFD, PWHT, beveled end, 3LPE/FBE coating ikupezeka. Kupereka mwachindunji kwa mafakitale kwa mapulojekiti a sour oil ndi gasi padziko lonse lapansi.

1. Womic Steel: Mphamvu Zopangira & Mphamvu za Kampani pa Utumiki wa X52 Sour

Womic Steel Group imagwiritsa ntchito mizere yapadera yopangira mapaipi a LSAW omwe ali ndi sour service. Ntchito ya sour ya X52 PSL2 imafuna:

● Mpweya wochepa wa kaboni (CEV ≤ 0.40%, wamba ≤ 0.38%)

● Sulfure yochepa (S ≤ 0.002%) ndi phosphorous yochepa (P ≤ 0.015%)

● Chithandizo cha calcium chowongolera mawonekedwe ophatikizika (globular sulfides)

● Chithandizo cha kutentha pambuyo pa weld (PWHT) cha mapaipi onse, mosasamala kanthu za makulidwe a khoma

● Kuyesa kuuma kwa 100% (kuwotcherera, HAZ, chitsulo choyambira)

● Kuyesa kwa HIC ndi SSC motsatira miyezo ya NACE

Njira zopangira: JCOE, UOE, mbale yozungulira yokhala ndi ng'anjo yofunikira ya PWHT (yokhala pansi pa galimoto, kutalika kwa 12m, kunyowa kwa 600°C). Kuyang'aniridwa ndi SGS, BV, TÜV, DNV, kapena ABS ndi gulu lachitatu kuti apeze satifiketi yonse ya ntchito yowawa.

Kuchuluka kwa ntchito ya pachaka ya sour X52 LSAW:Matani 30,000.

Kusinthasintha kwa Kupanga kwa Sour Service X52 PSL2:

JCOE: 406–1,422mm OD × 6.0–50.8mm WIT × ≤ 18m

UOE: 508–1,220mm OD × 6.0–40.0mm WIT × ≤ 24m (yomwe imakonda kukhala yowawa chifukwa cha kupsinjika kochepa)

Mbale yozungulira: 600–1,600mm OD × 25–60mm Kulemera × ≤ 12m

Mapaipi onse oyeretsera madzi amalandira PWHT (600°C ± 10°C, amasunga ola limodzi pa makulidwe a 25mm, kuziziritsa pang'onopang'ono)

2. API 5L X52 PSL2 Utumiki Wopanda Mphamvu: Kapangidwe ka Zinthu & Makhalidwe Abwino

Pa ntchito ya sour, chemistry ndi yolimba kuposa PSL2 yokhazikika. Cholinga chake ndikupeza kukana kwakukulu ku HIC ndi SSC m'malo onyowa a H₂S.
