Tsananguro pfupi:

Womic Steel inopa pombi dzesimbi dzemhando yepamusoro dzeASTM A252 Giredhi 2 LSAW dzekugadzira makomba ehwaro, mapiers emabhiriji, nheyo dzekuvaka, uye zvivakwa zvemugungwa. Giredhi 2 rinopa simba rekugadzira 240 MPa (35,000 psi) uye simba rekusunga 415 MPa (60,200 psi), zvichiita kuti ive giredhi rakatsanangurwa zvakanyanya rekushandisa makomba ehwaro. Maitiro eLSAW anosanganisira nzira dzekugadzira makomba dzeJCOE, UOE, uye nzira dzekugadzira makomba epurasitiki akaputirwa, zvichipa musono wakatwasuka wenguva refu une kugadzikana kwakanaka. Kune dhayamita hombe kana kuti makomba emadziro anorema (kusvika pakukora kwemadziro kwe80mm), Womic inoshandisa plate rolling uye multi-pass submerged arc welding. Dhayamita yekunze kubva pa219mm kusvika 3,000mm (8″ – 120″), ukobvu hwemadziro kubva pa6.0mm kusvika 80mm, kureba kusvika pa60m. Chitupa chemugayo, bvunzo ye ultrasonic 100% (weld seam), magumo akachekwa kana asina kujeka, uye anti-corrosion coating (coal tar epoxy, bitumen, zinc) zviripo. Zvakakodzera mabhesi ebhiriji, maport piling, kuvaka mabhesi akadzika, macofferdams, madziro ekuchengetedza, uye ma road piling.

Saizi yepombi yesimbi yeLSAW:Dhayamita yekunze: 219mm – 3,000mm (8″ – 120″), Ukobvu hwemadziro: 6.0mm – 80mm (JCOE/UOE max 50.8mm, plate yakakungurutswa max 80mm), Kureba: 6m – 18m yakajairwa, urefu hwakatarwa hunosvika 60m

1. Simbi yeWomic: Kugona Kugadzira & Simba reKambani

Womic Steel Group inoshandisa mitsetse yakawanda yekugadzira LSAW yekushandisa pakuronga. ASTM A252 Giredhi 2 ndiyo giredhi rebasa rekuisa hwaro, ichipa kuenzana kwesimba uye ductility yemapombi anofambiswa. Maitiro eLSAW akanakira kuisa dhayamita hombe kupfuura kugona kweERW.

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

● Mutsetse weUOE:Kune dhayamita 508mm – 1,220mm (20″–48″), ukobvu hwemadziro hunosvika 40mm.

● Purati Yakamonerwa (Musono Mumwe Chete):Kune dhayamita 600mm – 3,000mm (24″–120″), ukobvu hwemadziro hunobva pa25mm kusvika 80mm.

● Purati Yakamonerwa (Musono Wakakombama):Kune dhayamita 1,200mm – 3,000mm (48″–120″), ukobvu hwemadziro hunosvika 80mm.

Huwandu hwese hweLSAW hunopfuura matani 300,000 pagore, nekugadzirwa kweA252 Grade 2 kunodarika matani 100,000 pagore. Womic Steel ine ISO 9001, uye inogona kupa kuongororwa kwevamwe neSGS, BV, TÜV. Mapaipi eA252 anodarika makiromita 800 anopihwa pasi rose.

Mibvunzo Inowanzo bvunzwa:

Mubvunzo: Ndeupi musiyano uripo pakati peASTM A252 Giredhi 2 neGiredhi 3 pakuunganidza zvinhu?
A: Giredhi rechitatu rine simba rakawanda (345 MPa vs 240 MPa goho) uye rinoshandiswa pakuisa hwaro hwakadzika kana kuti pakuisa mutoro wakakwira. Giredhi rechipiri rinodhura zvishoma uye rakakwana pakuisa hwaro hwakawanda (mabhiriji, zvivakwa, madoko). Sarudza Giredhi rechipiri pakuisa mutoro wakajairika, Giredhi rechitatu pakuisa mutoro unorema kana kutyaira wakadzama.

Mubvunzo: Munopa mapaipi eA252 Grade 2 ane galvanized coating here?
A: Ehe. Tinopa galvanizing inodziya paASTM A123. Kureba kwakanyanya kwe galvanizing i12.5m. Kune mirwi yakareba, tinokurudzira epoxy coating kana bituminous coating.

Mubvunzo: Hurefu hwakanyanya sei hwaunogona kugadzira paipi yeGiredhi 2?
A: Kureba kwechikamu chimwe chete i18m (JCOE) kana 24m (UOE). Kune hurefu hunosvika 60m, tinosundira zvikamu zvakawanda kubva kumagumo kusvika kumagumo neSAW circumferential welds dzinopinda mukati (100% UT inoongororwa). Izvi zvakajairika kune mhepo dzinobhururuka dziri kunze kwenyika.

Mubvunzo: Ko ASTM A252 inoda kuongororwa kwemvura here?
A: Kwete. ASTM A252 haidi kuyedzwa kwemvura inoyerera nekuti mapaipi ekuisa makomba haapindi simba. Zvisinei, kana chirongwa chako chichida kuyedzwa kwemvura (semuenzaniso, kwekuiswa kwemakomba pamwe chete uye kutakurwa kwemvura), tinogona kuzviita nemutengo wekuwedzera.

Mubvunzo: Ndechipi chifukidziro chinokurudzirwa pakuunganidzwa kwemvura yemunyu mumvura yegungwa?
A: Pakunyudzwa mumvura yegungwa, tar epoxy yemalahle (600-800 microns) kana glass flake epoxy zvinokurudzirwa. Kune nzvimbo dzinoshandiswa pakuisa mvura, tinokurudzira FBE kana epoxy coatings yakakora. Kune mvura yakachena kana ivhu, pombi nhema isina chinhu kana pamusoro pemafuta zvinowanzo kukwana.

Q: Unoita sei kuti ma welds arambe aripo nekushandisa nyundo?
A: Tinoita bvunzo yekupeta (inosungirwa) uye bvunzo yekukombama yakatungamirirwa pasampuli dzeweld. Kune mapombi anotungamirirwa ne critical, tinoitawo 100% UT ye weld seam uye MPI yezvigunwe zveweld. Tinogona zvakare kupa Charpy impact testing pa0°C kana pasi kana zvataurwa.

Q: Ndeipi nguva yakajairika yekuisa mapaipi eGiredhi 2?
A: Nguva yakatarwa yekutungamira: mazuva 25-35 edhayamita ≤ 1,422mm. Kune dhayamita hombe yakamonerwa (> 1,422mm): mazuva 35-50. Kune mirwi yakareba yakasungirirwa (kusvika 60m): wedzera mavhiki maviri.

Huwandu:Mamita 42,000 (makiromita 42), matani angangoita 10,800

Magadzirirwo:Migumo isina chinhu (yakachekwa sikweya), coating yemarasha epoxy (800 microns), bvunzo yekupeta (hapana mitswe pa 1/3 dhayamita yekupeta). bvunzo yekukombama yakatungamirirwa ye weld ductility. 100% UT ye weld seam. Charpy impact pa 0°C (min 27J, yakasvika 50-80J). Kutwasuka ≤ 0.2%. Kuongororwa kwechitatu neSGS Netherlands.

Kushandiswa:Kuwedzerwa kwenzvimbo yekuisa makontena paMaasvlakte 2, Port of Rotterdam. Mapombi esimbi anoshanda sehwaro hwemadziro egungwa (mapombi anotakura mutoro wakatwasuka) uye semapombi emadolphin anosungirirwa (mapaipi anotakura mutoro wakatwasuka). Kudzika kwemvura panzvimbo yekumisa: 18m. Ivhu rine jecha nevhu rakapfava.

Matambudziko ehunyanzvi nemhinduro:

●Kudzivirira ngura yenzvimbo dziri kumahombekombe– Kunyudzwa mumvura ine munyu uye nzvimbo yekupfapfaidza kwaida kuputirwa kwakasimba. Madzimai akaisa tar epoxy yemarasha (800 microns DFT) ine zvikamu zviviri. Kuputirwa kwakapfuura bvunzo yekupfapfaidza munyu kwemaawa 3,000 (ASTM B117) ine <2mm creep kubva kuscribe. Kuonekwa kwezororo pa4kV pasina kukundikana.

●Mirwi mirefu yenzvimbo yekurara mvura yakadzika– Hurefu hwemurwi hunodiwa hwemamita makumi maviri nemasere (18m kusvika pasi pegungwa + 10m pamusoro pemugero wevhu). Majoini akajairwa e12m anoda majoini matatu emunda. Womic yakapa majoini akareba 18m (plate yakamonerwa) kumapoinzi e1,016mm, zvichideredza majoini kubva pa3 kusvika pa2 pamurwi wega wega. Pamapoinzi akakosha ekunamatira, takapa mapoinzi akareba 28m nekusveta zvikamu zviviri zve14m (100% UT yakaongororwa).

●Kunetseka kwakanyanya mujecha rakakora– Hunhu hwevhu hunosanganisira jecha rakakora rine SPT N-values ye40-60. Kumanikidzwa kwemurwi kwakaswedera pedyo ne70% yesimba remukoho.
