1. Insimbi Yomdabu: Amakhono Okukhiqiza kanye Namandla Enkampani
I-Womic Steel Group isebenzisa imigqa eminingi yokukhiqiza ye-LSAW ekwazi ukukhiqiza amapayipi esakhiwo e-ASTM A500 Grade C. I-A500 Grade C iyipayipi lesakhiwo lensimbi yekhabhoni elihlanganisiwe elibandayo (“elibandayo” libhekisela ekushiseni okwakhayo, hhayi ukwelashwa kokushisa ngemva kokushiswa). Inqubo ye-LSAW ilungele izingxenye zesakhiwo eziyindilinga ezinkulu ezinobubanzi obungaphezu kwamandla e-ERW noma ama-mill angenamthungo.
●Umugqa we-JCOE:Kuma-diameter angu-406mm – 1,422mm (16″–56″), ubukhulu bodonga bufika ku-50.8mm. Kufanelekela ukwakha amakholomu kanye namalungu e-bridge truss.
● Umugqa we-UOE:Kumadayamitha angu-508mm – 1,220mm (20″–48″), ubukhulu bodonga obufika ku-40mm. Ikhiqiza ukujiya okuphezulu kwensimbi yokwakha eveziwe.
● Ipuleti Eligoqiwe (Umthungo Owodwa):Kuma-diameter angu-600mm – 2,500mm (24″–98″), ubukhulu bodonga busukela ku-25mm kuya ku-80mm. Kuhle kakhulu kumakholomu odonga asindayo kanye nemilenze yombhoshongo wokudlulisa.
● Ipuleti Eligoqiwe (Umthungo Ophindwe Kabili):Kumadayamitha angu-1,200mm – 2,500mm (48″–98″), ubukhulu bodonga bufika ku-80mm.
Inani lamandla e-LSAW lidlula amathani angu-300,000 ngonyaka, kanti ukukhiqizwa kwe-A500 Grade C kudlula amathani angu-80,000 ngonyaka. I-Womic Steel ine-ISO 9001, futhi ingahlinzeka ngokuhlolwa okuvela eceleni yi-SGS, BV, TÜV. Izinkulungwane zamathani e-A500 Grade C zihlinzekwa ngamaphrojekthi engqalasizinda yase-US (amabhuloho, izinkundla zemidlalo, izitshalo zezimboni).
Ukuguquguquka Kokukhiqiza kwe-A500 Grade C:
I-JCOE: 406–1,422mm OD × 5.0–50.8mm Isisindo × ≤ 18m
I-UOE: 508–1,220mm OD × 5.0–40.0mm Isisindo × ≤ 24m
Ipuleti eligoqiwe (umthungo owodwa): 600–2,500mm OD × 25–80mm Isisindo × ≤ 18m
Ipuleti eligoqiwe (umthungo ophindwe kabili): 1,200–2,500mm OD × 25–80mm Ubude × ≤ 18m
Amapayipi anganikezwa nge-primer coating (i-epoxy ecebile nge-zinc, ama-micron angu-40-80), engenalutho (efakwe uwoyela), noma efakwe i-hot-dip galvanized.
2. I-ASTM A500 Ibanga C: Ukwakheka Kwezinto Nezimpawu Zokusebenza

Imibuzo ejwayelekile ukubuzwa:
U: Uyini umehluko phakathi kwe-ASTM A500 Grade C kanye ne-ASTM A53 GR.B yepayipi lesakhiwo?
A: Ibanga C linamandla aphezulu kakhulu: isivuno esingu-345 MPa vs 240 MPa se-A53. Ibanga C liphinde libe nokubekezelelana okuqinile futhi lidinga ukuhlolwa kokuthamba. Kumakholomu nama-trusses athwala umthwalo, iBanga C liyathandwa. I-A53 GR.B iyamukeleka kumalungu esibili kanye nezakhiwo ezingabalulekile.
U: Ingabe i-ASTM A500 idinga ukuhlolwa komthelela (i-Charpy)?
A: Cha. I-ASTM A500 ayikugunyazi ukuhlolwa komthelela we-Charpy. Kodwa-ke, ngezicelo zokushisa okuphansi (isb., i-Arctic, amanye amakhodi ebhuloho), onjiniyela bangase bangeze izidingo ezengeziwe. I-Womic inganikeza ukuhlolwa komthelela we-Charpy ngezindleko ezengeziwe (ngokuvamile ku-0°C noma -20°C) uma kuchaziwe.
U: Ungakwazi yini ukunikeza i-A500 Grade C i-hot-dip galvanizing yokusetshenziswa ngaphandle?
A: Yebo. Sinikeza i-hot-dip galvanizing ngokwe-ASTM A123. Ubude obukhulu bebhavu lethu le-galvanizing bungu-12.5m. Kumapayipi amade, singahlela i-sectional galvanizing noma sisebenzise enye indlela yokugqoka (i-epoxy ecebile nge-zinc). Sicela ucacise izidingo zakho zobude.
Q: Bungakanani ubude obukhulu ongabukhiqiza ngepayipi le-A500 Grade C LSAW?
A: Ubude obujwayelekile obuphezulu bungu-18m (JCOE) noma u-24m (UOE) wobubanzi obungu-≤ 1,220mm. Kumadayamitha amakhulu (ipuleti eligoqiwe), ubude obuphezulu buvame ukuba ngu-12-18m ngenxa yemikhawulo yosayizi wepuleti. Kumade angaphezu kuka-18m, singashisela izingxenye eziningi kusukela ekuqaleni kuya ekugcineni (ama-circumferential SAW welds). Xhumana nathi ngezidingo zakho ezithile.
U: Ingabe niyahlola amapayipi e-A500 Grade C ngaphandle komuntu wesithathu?
A: Yebo. Sisebenzisana ne-SGS, i-BV, i-TÜV, kanye nezinye izinhlaka. Ukuhlola kungafaka phakathi ukuhlolwa okubonakalayo nobukhulu, ukuhlolwa kokuthamba, i-UT noma i-RT yama-welds, kanye nokuhlolwa kwamakhemikhali/ukuthamba. Sikhipha izitifiketi ze-EN 10204 Type 3.1 njengezijwayelekile; Uhlobo 3.2 luyatholakala uma luceliwe.
Q: Yisiphi isikhathi esijwayelekile sokuhola ipayipi lesakhiwo le-A500 Grade C LSAW?

Lo msebenzi wawudinga insimbi eveziwe enokuphela okubushelelezi kokushiswa kanye nokubukeka okufanayo.
Izinselele Zobuchwepheshe Nezixazululo:
● Insimbi eveziwe yezakhiwo - ukugaya nokuqeda ukushisela– Imibhoshongo ibonakala enkundleni yezemidlalo nasezindaweni ezizungezile. I-Womic yenze ukugaya ngokuzenzakalelayo kwe-weld kulandelwe ukuqeda ngesandla ukuze kufezwe indawo ebushelelezi (Ra ≤ 6.3μm). Siphinde safaka i-primer coating efanayo (i-epoxy ecebile nge-zinc, umbala ompunga okhanyayo ochazwe ngumklami). Ipayipi ngalinye lihlolwe ukuthi libushelelezi yini kwe-weld yithimba le-QA leklayenti.
● Izidingo zendawo yokuzamazama komhlaba – ukuqina nokuqina– ILos Angeles isesigabeni D sokuklama i-Seismic Design (ingozi ephezulu yokuzamazama komhlaba). I-ASTM A500 Grade C ngokuvamile ayidingi ukuhlolwa kokuthinteka. Unjiniyela wesakhiwo wengeze isidingo somthelela we-Charpy esingu-27J ku-0°C. Amapuleti e-Womic akhethwe anekhabhoni elawulwayo (0.20-0.22%) kanye ne-manganese (1.15-1.25%) futhi afinyelela ku-60-90J ku-0°C, ngaphezu kakhulu kwesidingo.
●Izingxenye ezinkulu ezinobubanzi obuncane– Eminye imilenze yombhoshongo yayinciphile (emise okwekhoni). I-Womic yanikeza amapayipi aqondile abese enziwa yinkontileka abe yizingxenye ezinciphile. Sinikeze ukulawula okuqinile kwe-ovality (≤ 0.5%) ukuze kube lula inqubo yokunciphisa. Amapayipi amakwe ngemigqa yokuqondisa ukuqinisekisa ukushisela okuqhubekayo.
●Isembozo sokuqala semvelo yasogwini– Inkundla yezemidlalo iSoFi itholakala ngamakhilomitha ama-5 ukusuka ePacific Ocean, lapho kutholakala khona usawoti ochayeka khona. I-epoxy primer ecebile nge-zinc (60 microns) yafakwa kuwo wonke amapayipi. Isembozo sidlule ukuhlolwa kosawoti ochayeka amahora ayi-1,000 (ASTM B117) ngokucwila okungaphansi kwama-2mm kusuka ku-scribe. Ukutholwa kwamaholide ku-2kV ngaphandle kokwehluleka.
●Ukuthunyelwa kwezinto kuya endaweni yokwakha esebenzayo– Ukuthuthukiswa kweHollywood Park kungenye yezinhlelo ezinkulu zokwakha zasemadolobheni e-US. Ukulethwa kwamapayipi amakhulu angamathani angu-2,340 kwakudingeka kuhlelwe ngokulandelana. I-Womic ilethe amapayipi ngokuthunyelwa okungu-6 ezinyangeni ezingu-8, ngalinye lihlelelwe ukufika ngaphambi nje kokufakwa. Amapayipi athunyelwa esuka eShanghai aya ePort of Los Angeles, ayesethuthwa ngamaloli amakhilomitha angu-8 aye endaweni. Sisebenzise izitsha ezisicaba zamapayipi angu-1,016mm kanye no-1,220mm ukuze sigweme umonakalo.
●Izidingo ze-US Buy America– Lo msebenzi wawudinga ukuxolelwa kwensimbi yangaphandle ngoba izigayo zasekhaya zase-US azikwazanga ukukhiqiza ububanzi obukhulu (1,220mm) ngobukhulu bodonga obudingekayo ngaphakathi kwesheduli. I-Womic inikeze amadokhumenti agcwele afaka phakathi izitifiketi zomshini, izwe lokuvela kulo, kanye nokulandeleka kwezinto. Ukuxolelwa kwavunyelwa ngumnikazi.
●Umphumela:Izakhiwo zombhoshongo wokudlulisa amandla zaqedwa ngo-2022. Seziyisici esibonakalayo sesakhiwo seSoFi Stadium. Usonkontileka ubike ukuthi wonke amapayipi e-LSAW alingana kahle ngaphandle kokulungiswa kabusha. Ukuphela kwensimbi eveziwe kwathola udumo kumklami. Kusukela lapho i-Womic Steel imenyiwe ukuthi ibhide kumaphrojekthi engeziwe ensimbi yokwakha e-US.

Insimbi Yom-Womic – Umlingani wakho othembekile wamapayipi ensimbi e-ASTM A500 Grade C LSAW okwakha izinsika, ama-bridge trusses, imibhoshongo yokudlulisa, kanye nezinhlelo zokusebenza ezisindayo zesakhiwo emhlabeni jikelele.
