1. Womic Steel: Mphamvu Zopangira ndi Mphamvu za Kampani

Womic Steel Group ndi kampani yopanga zinthu zapamwamba komanso yotumiza kunja padziko lonse lapansi yokhala ndi zaka zoposa 20 zaukadaulo popanga zinthu zopangidwa ndi kaboni, aloyi, ndi zitsulo zosapanga dzimbiri. Malo athu opangira mapaipi a LSAW apamwamba kwambiri (njira ya JCOE) ali ndi mphamvu yoposa matani 250,000 pachaka pa mapaipi olumikizidwa ndi arc, omwe amatumikira madzi, mafuta, gasi ndi mapulojekiti omanga m'makontinenti asanu.

Kukula kwa Kupanga kwa Chitoliro cha Chitsulo cha LSAW:M'mimba mwake wakunja kuyambira 219mm mpaka 1,422mm (mainchesi 8 mpaka 56 mainchesi) kudzera mu kupanga kwa JCOE. Kukhuthala kwa khoma kuyambira 5.0mm mpaka 50.8mm. Kutalika kwa munthu m'modzi kuyambira 6m mpaka 12m, ndi kutalika kwapadera mpaka 24m komwe kulipo pa ntchito za mapaipi ndi zomangira zomwe zimafuna malo olumikizirana atali.

Zitsimikizo Zaubwino & Kutsatira Malamulo:

● ISO 9001:2015 Yovomerezekapa kayendetsedwe kabwino ka kupanga kwa LSAW.

Mafunso Ofunsidwa Kawirikawiri:

Q: Kodi pali kusiyana kotani pakati pa LSAW ndi SSAW pa chitoliro cha GR.B?
Yankho: LSAW ili ndi msoko wowongoka (kutalika kwa weld yofupikitsa) ndipo nthawi zambiri imakondedwa pakakhala kupanikizika kwakukulu, makoma okhuthala, komanso malo owawa. SSAW ndi yotsika mtengo pa mainchesi akuluakulu kwambiri (>56″) koma ili ndi weld yozungulira yayitali.

Q: Kodi mungapereke mayeso a GR.B PSL2 ndi impact test?
A: Inde. PSL2 ili ndi 27J @ 0°C Charpy impact, chemistry yolimba, ndi malire a kuuma. Yoyenera malo otentha kwambiri mpaka -20°C.

Q: Ndi chophimba chiti chomwe chikulimbikitsidwa pa mapaipi amadzi?
Yankho: Pa mitsinje yamadzi yobisika, 3LPE kapena epoxy yamadzimadzi ndi yofala. Pa epoxy yomwe ili pamwamba pa nthaka, FBE kapena epoxy yokhala ndi zigawo ziwiri. Timapereka zosankha zonse.

Q: Kodi mumapereka satifiketi ya EN 10204 3.2?
A: Inde, tikapempha timakonza zoti mabungwe odziwitsidwa ndi EU monga TÜV kapena BV aziyang'ane ndikupereka satifiketi 3.2.

Chitsimikizo cha Pulojekiti - Pulojekiti Yopereka Madzi ku Municipal Bangladesh

Dziko:Bangladesh
Muyezo ndi Giredi:API 5L GR.B PSL1
Miyeso ndi Kuchuluka:OD 914mm (36″) × Kulemera 9.5mm, kutalika kwa 12m, matani onse 1,250 (pafupifupi 2.8 km)
Mafotokozedwe:Malekezero opanda kanthu, chophimba chakunja cha 3LPE (kukhuthala kwa 2.5mm), hydrotest pa 1.8 MPa, 100% UT pa msoko wothira ndi thupi la chitoliro.
Ntchito:Kutumiza madzi akumwa a boma kuchokera ku Mtsinje wa Meghna kupita ku chigawo cha Narayanganj, komwe kumatumikira anthu 500,000.

Mavuto aukadaulo:

● Njira ya payipi inadutsa ngalande zitatu zamadzi zomwe zinali ndi dothi lofewa la alluvial. Chiwopsezo chosiyana cha kukhazikika chinali chachikulu. Womic Steel inapereka mapaipi okhala ndi kulekerera kwa OD (± 0.3%) kuti atsimikizire kuti pakhale mgwirizano wodalirika wa gasket wa rabara (zolumikizira zogwiritsidwa ntchito m'munda).

● Madzi apansi panthaka ambiri adayambitsa mavuto okhudzana ndi kusweka kwa chivundikiro panthawi yoyika. Tinayikapo gawo lina la epoxy primer yolumikizidwa ndi fusion tisanayambe kugwiritsa ntchito 3LPE, zomwe zinapangitsa kuti chivundikirocho chikhale cholimba > 150 N/cm pa 70°C (yoyesedwa ndi SGS).

● Zoletsa kutumiza: mapaipi anayenera kutumizidwa ku doko la Chittagong mkati mwa masiku 40. Womic adagwirizana ndi COSCO kuti apeze malo osungira sitima ndipo adatumizidwa mkati mwa masiku 38.

Zotsatira:Mapaipi onse adayesedwa ndi SGS ndi anthu ena. Palibe masiku opukutira omwe adapezeka atapezeka ndi tchuthi 100%. Paipiyo idayamba kugwira ntchito mu 2022 ndipo ikugwirabe ntchito popanda kutayikira konse.
