Tsananguro pfupi:

Womic Steel inopa pombi dzesimbi dzemhando yepamusoro dzeASTM A500 Giredhi C LSAW dzemhando yepamusoro dzekushandisa mukuvaka dzinoda simba rakawanda kupfuura Giredhi B. Giredhi C inopa simba rekugadzira 345 MPa (50,000 psi) uye simba rekudhonza 485 MPa (70,300 psi), zvichiita kuti ive sarudzo inofarirwa pakuvaka makoramu, mabhuroko, mashongwe ekutumira, uye zvinotsigira michina inorema. Maitiro eLSAW anosanganisira nzira dzeJCOE, UOE, uye nzira dzekubatanidza maplate akaputirwa, zvichipa musono wakatwasuka wenguva refu une kugadzikana kwakanaka. Kune mapaipi emadziro ane dhayamita yakakura kana anorema (kusvika pakukora kwemadziro kwe80mm), Womic inoshandisa plate rolling uye multi-pass submerged arc welding. Dhayamita yekunze kubva pa219mm kusvika 2,500mm (8″ – 98″), ukobvu hwemadziro kubva pa5.0mm kusvika 80mm, kureba kusvika pa24m. Chitupa chemugayo, bvunzo ye ultrasonic 100% (weld seam), magumo akachekwa kana asina kujeka, uye anti-corrosion coating (primer, epoxy, hot-dip galvanizing) zviripo. Zvakakodzera ma frame ekuvaka, bridge chords, crane booms, stadium trusses, transmission tower legs, offshore topside structures, uye ma industrial platforms.

Saizi yepombi yesimbi yeLSAW:Dhayamita yekunze: 219mm – 2,500mm (8″ – 98″), Ukobvu hwemadziro: 5.0mm – 80mm (JCOE/UOE yakanyanya 50.8mm, plate yakakungurutswa yakanyanya 80mm), Kureba: 6m – 18m yakajairwa, urefu hwakatarwa hunosvika 24m

1. Simbi yeWomic: Kugona Kugadzira & Simba reKambani

Womic Steel Group inoshandisa mitsetse yakawanda yekugadzira LSAW inokwanisa kugadzira mapaipi ekuvaka eASTM A500 Grade C. A500 Grade C ichubhu yekuvaka yesimbi yekabhoni yakagadzirwa nesimbi inotonhora ("inotonhora" inoreva tembiricha yekugadzira, kwete kurapwa kwekupisa mushure mekuwedhwa). Maitiro eLSAW akanakira zvikamu zvakakura zvechivakwa zvakatenderera zvinopfuura kugona kweERW kana mill isina musono.

●Mutsetse weJCOE:Kune dhayamita 406mm – 1,422mm (16″–56″), ukobvu hwemadziro hunosvika 50.8mm. Yakakodzera kuvaka makoramu nemidziyo yebhiriji.

● Mutsetse weUOE:Kune dhayamita 508mm – 1,220mm (20″–48″), ukobvu hwemadziro hunosvika 40mm. Inogadzira denderedzwa rakakura resimbi yekuvaka yakavhurika.

● Purati Yakamonerwa (Musono Mumwe Chete):Kune dhayamita 600mm – 2,500mm (24″–98″), ukobvu hwemadziro hunobva pa25mm kusvika 80mm. Yakanakira mapuranga anorema emadziro nemakumbo eshongwe yekutumira.

● Purati Yakamonerwa (Musono Wakakombama):Kune dhayamita 1,200mm – 2,500mm (48″–98″), ukobvu hwemadziro hunosvika 80mm.

Huwandu hwese hweLSAW hunodarika matani 300,000 pagore, nekugadzirwa kweA500 Grade C kunodarika matani 80,000 pagore. Womic Steel ine ISO 9001, uye inogona kupa kuongororwa kwevamwe neSGS, BV, TÜV. Matani zviuru zveA500 Grade C anopiwa kumapurojekiti ezvivakwa zveUS (mabhiriji, nhandare dzemitambo, mafekitori emaindasitiri).

Kuchinjika Kwekugadzira kweA500 Giredhi C:

JCOE: 406–1,422mm OD × 5.0–50.8mm Uremu × ≤ 18m

UOE: 508–1,220mm OD × 5.0–40.0mm Uzito × ≤ 24m

Pureti yakamonerwa (musono mumwe chete): 600–2,500mm OD × 25–80mm Uremu × ≤ 18m

Pureti yakamonerwa (musono wakakombama): 1,200–2,500mm OD × 25–80mm Uremu × ≤ 18m

Mapaipi anogona kupihwa ne primer coating (epoxy ine zinc yakawanda, 40-80 microns), isina mafuta (yakazorwa), kana kuti yakabatidzwa nekupisa.

2. ASTM A500 Giredhi C: Kuumbwa kwezvinhu & Hunhu hwekushanda

ASTM A500 Giredhi C ndiyo giredhi repamusoro-soro muA500 specification ye cold formed welded carbon steel structural tubes. Simba repasi pe 345 MPa (50,000 psi) uye simba re tensile re485 MPa (70,300 psi). Yakasimba ne25% kupfuura Giredhi B (inorema 290 MPa, tensile 400 MPa). Giredhi C inowanzo tsanangurwa kune mashandisirwo e structure anorema.

Kuumbwa kweMakemikoro (yakanyanya % nehuremu - ASTM A500 haimanikidze miganhu yakasimba, asi miganhu yakajairika):

Womic yakaita otomatiki yekukuya weld ichiteverwa nekupedzisa nemaoko kuti iite kuti pamusoro payo pave pakanaka (Ra ≤ 6.3μm). Takaisawo primer coating yakafanana (zinc-rich epoxy, ruvara rwegrey rwakajeka rwakatsanangurwa nemugadziri wezvivakwa). Pombi yega yega yakaongororwa kuti ionekwe kuti weld yakapfava here nechikwata cheQA chemutengi.

● Zvinodiwa munzvimbo ine kudengenyeka kwenyika - kugona kugadzikana uye kusimba– Los Angeles iri muchikamu cheSeismic Design Category D (njodzi huru yekunyungudika kwenyika). ASTM A500 Giredhi C kazhinji haidi kuyedzwa kwekukanganisa. Mainjiniya wekuvaka akawedzera chinodiwa chekukanganisa kweCharpy che27J pa0°C. Womic yakasarudza maplate ane kabhoni inodzorwa (0.20-0.22%) uye manganese (1.15-1.25%) uye yakawana 60-90J pa0°C, iri pamusoro pechinodiwa.

●Zvikamu zvakakura zvakatetepa– Mamwe makumbo eshongwe akanga akatetepa (akaita sekona). Womic yakapa mapaipi akatwasuka ayo akazogadzirwa nemukondirakita muzvikamu zvakatetepa. Takapa kudzora kwakasimba kweovality (≤ 0.5%) kuti zvive nyore kuita kuti tambo itetepa. Mapaipi akaiswa mutsetse wekutarisa kuti ave nechokwadi chekuti tambo yacho inonamirwa zvakanaka.

●Kuputira kwekutanga kwenzvimbo dzegungwa– Nhandare yeSoFi iri makiromita mashanu kubva kuPacific Ocean, ine munyu wakawanda. Epoxy primer (60 microns) yakaiswa pamapaipi ese. Coating yakapasa bvunzo yekupfapfaidza munyu kwemaawa chiuru (ASTM B117) isina kudzika kwe2mm kubva kuscriber. Kuonekwa kwezororo pa2kV pasina kukundikana.

●Kuenda kunzvimbo yekuvaka iri kushanda– Kuvandudzwa kweHollywood Park ndeimwe yemapurojekiti makuru ekuvaka maguta muUS. Kutumirwa kwematani 2,340 emapombi makuru kwaifanira kurongwa. Womic yakaendesa mapaipi muzvikamu zvitanhatu mukati memwedzi misere, imwe neimwe yakarongerwa kusvika nguva pfupi isati yaiswa. Mapaipi akatumirwa kubva kuShanghai kuenda kuPort of Los Angeles, ndokuzoendeswa nerori makiromita masere kunzvimbo iyi. Takashandisa magaba efurati rakatsetseka emapaipi e1,016mm ne1,220mm kudzivirira kukuvara.

●Zvinodiwa zveUS Buy America- Chirongwa ichi chaida kusunungurwa kwesimbi yekune dzimwe nyika nekuti makambani ekuAmerica emuno aisakwanisa kugadzira dhayamita hombe (1,220mm) muukobvu hwemadziro hwaidiwa mukati menguva yakatarwa. Womic akapa magwaro akazara anosanganisira zvitupa zvemagetsi, nyika yaakabva, uye kurongeka kwezvinhu. Kusunungurwa kwacho kwakatenderwa nemuridzi.

●Mhedzisiro:Zvivakwa zveshongwe yemagetsi zvakapedzwa muna 2022. Zvave chinhu chinozivikanwa muSoFi Stadium complex. Muvaki akataura kuti mapaipi ese eLSAW aikwana zvakanaka pasina kugadziriswazve. Kupera kwesimbi kwakaburitswa kwakarumbidzwa nemugadziri wezvivakwa. Womic Steel yakakokwa kuti ikwidze mapurojekiti ekuwedzera esimbi muUS.
