Ukuqedwa Komphezulu

Ukumelana nokugqwala kungenye yezinto ezibaluleke kakhulu kumaphrojekthi olwandle nolwandle.

I-Royal Steel Group inikeza izixazululo eziningi zokulwa nokugqwala:

Ubuso Bensimbi Emnyama

Ifanele ukwakhiwa ngaphakathi ezweni kanye nokucubungula okwesibili.
Isembozo se-Fusion Bonded Epoxy (FBE)

Inikeza ukumelana okuhle kakhulu kwamakhemikhali kanye nokuvikelwa kwesikhathi eside.

Uhlelo Lokumboza lwe-3PE

Kuqukethe:

I-primer ye-Epoxy
Isendlalelo esinamathelayo
Ingqimba yangaphandle ye-polyethylene

Lolu hlelo lusetshenziswa kabanzi kumaphrojekthi olwandle, izakhiwo zasogwini lolwandle, kanye nezisekelo zamapayipi.

Indawo ye-FBE

Ubuso Bamafutha Amnyama

Isicelo Esiyinhloko

1. Izisekelo Zodonga Olungaphansi:Izisekelo zenqwaba zesakhiwo esingaphansi kwezakhiwo ezinezitezi eziningi, amafektri, izindawo zokugcina impahla, izakhiwo zebhizinisi nezindawo zokuhlala (ezifanele noma yiluphi uhlobo lwesakhiwo).

2. Izisekelo Zezinqwaba Zebhuloho:Izisekelo eziqinile zamabhuloho omgwaqo omkhulu, amabhuloho esitimela kanye nemigwaqo yasemadolobheni; zifanelekela amabhuloho alula, alula, aqinile noma antantayo ahlanganisa imifula, amachibi kanye nolwandle.

3. Ukwakhiwa Kwechweba:Izisekelo ezithembekile zezindawo zokupaka imikhumbi, izindawo zokupaka imikhumbi kanye namapulatifomu echweba, kanye nezindawo zokuphatha imishini esindayo kanye nezimpahla.

4. Amaphrojekthi Obunjiniyela Bamandla Omoya Nomoya Wasolwandle Nasezindaweni Zasogwini:Imikhiqizo yesakhiwo semboni yasolwandle kanye nama-turbine omoya asogwini, anokumelana namagagasi, amagagasi kanye nokugqwala kolwandle.

5. Zonke Izinkampani Zobunjiniyela Bokwakha Ezinkulu:Izinqwaba ezithwala umthwalo omkhulu zamaphrojekthi amakhulu obunjiniyela bomphakathi njengamadamu, iziteshi zangaphansi komhlaba, imigudu, kanye nemishini yezimboni kanye nemithwalo yezakhiwo.

Inzuzo yeRoyal Steel Group (Kungani iRoyal Group ivelele kumakhasimende aseMelika?)

1) Ihhovisi Legatsha - ukwesekwa kwabantu abakhuluma iSpanishi, usizo lokuhlanza impahla, njll.

2) Amathani angaphezu kuka-5,000 esitokweni, anobukhulu obuhlukahlukene

3) Kuhlolwa izinhlangano ezigunyaziwe njenge-CCIC, i-SGS, i-BV, ne-TUV, kanye nokupakishwa okujwayelekile okufanele ulwandle

Ukupakisha Nokulethwa

1. Ukupakisha:

Amabhulokhi ezinkuni noma i-dunnage kusetshenziswa phakathi kwezingqimba zezikhwama zokupakisha noma izitsha ukuvimbela umonakalo ngesikhathi sokuthuthwa.

Ukwelashwa kwendawo (ongakukhetha): Upende omnyama, uwoyela wokuvimbela ukugqwala, noma imiqulu yefilimu yepulasitiki.

Izinqwaba ezifakwe ngogesi ezishisayo zingambozwa ngefilimu yokuvikela yesikhashana ukuvimbela ukuklwebheka kobuso.

Ukupakishwa okwenziwe ngokwezifiso kuyatholakala.

2. Ezokuthutha:

Ubude bokugoba kwesitoko: amamitha ayi-6, amamitha ayi-12. Ubude obungejwayelekile buyatholakala futhi uma ucela iphrojekthi.

Ilungele ezokuthutha olwandle, isitimela, noma umgwaqo.

Isikhathi sokulethwa ngokuvamile siyizinsuku eziyi-15-30 ngemuva kokuthola inkokhelo, kuye ngohlobo lomkhiqizo kanye nemininingwane.

Ifanele ukuthunyelwa kwamanye amazwe emhlabeni jikelele, kanye neqoqo eliphelele lemibhalo (isitifiketi sokuhambisana nemithetho, uhlu lokupakisha, i-bill of lading).

3. Ukuphatha Izinyathelo Zokuqapha:

Bopha amapayipi ngokuphephile usebenzisa i-crane noma i-forklift efakwe izinti noma izinti ukuze uvimbele ukuguguleka.

Gcina amapayipi endaweni eyomile, enomoya, futhi epholile ngaphambi kokufakwa ukuze uvimbele ukugqwala.

Ukuthunyelwa okukhulu/okukhuluphele ngokweqile kumele kuhambisane nemithethonqubo yezokuthutha yendawo.

Imibuzo Evame Ukubuzwa

1. Kungani i-ASTM A500 ifaneleka kumapayipi ayisisekelo ajulile?

I-ASTM A500 iyipayipi lensimbi elenziwe ngendlela ebandayo elinokubekezelelana okuqinile, isilinganiso samandla nesisindo esiphezulu, kanye nokusebenza okuzinzile kwesakhiwo, okuqinisekisa ukufakwa okunembile kwezinqwaba zesisekelo ezijulile zengqalasizinda esindayo.

2. Uyini umehluko phakathi kwe-ASTM A500 Grade B kanye ne-ASTM A500 Grade BIbanga C?

Ibanga B: Amandla okukhiqiza amancane angu-42,000 psi (290 MPa), afanelekela ama-pile ngaphansi kwemithwalo evamile.

Ibanga C: Amandla aphezulu okukhiqiza aphansi, afinyelela ku-46,000 psi (317 MPa), okuqukethwe okuphansi kwekhabhoni okuphezulu, okulungele amaphrojekthi anemithwalo eminingi, futhi unokushintshwa okuhle.

3. Yimuphi umehluko phakathi kwe-ASTM A500 ne-ASTM A252 ngezinqwaba zesisekelo?

I-A252 iyincazelo ejwayelekile yenqwaba yamapayipi; I-A500 inokumelana okuqinile kanye nobuso obubushelelezi, okwenza ifaneleke kakhulu ezisekelweni ezivulekile, zasolwandle, kanye nezisekelo ezinembile.

4. Ingabe izinqwaba zensimbi ze-A500 zingashintshwa ensimini?

Yebo. Ukulawula okuqukethwe yikhabhoni kanye ne-manganese kunciphisa okulingana nekhabhoni, kuvimbela ukuqhekeka okubandayo, futhi kusiza ukuxhumanisa endaweni.

5. Yiziphi izinhlobo zezingubo zokuvikela ukugqwala ezifanelekela izindawo zasolwandle/ezivezwe obala?

Izinketho ezintathu eziyinhloko: uwoyela we-Balck, upende we-3PE, kanye nopende we-FBE, ofanelekela izindawo ezingcolisayo zasogwini/zasolwandle.

6. Ungakwazi yini ukwenza ngokwezifiso ukucubungula ngokwemidwebo yephrojekthi?

Yebo, singakunikeza: ububanzi/ubukhulu bodonga obufanele ngokwezifiso, ubude bokusika obungaguquki, ama-bevel, amapuleti okugcina, izisekelo zokushayela, kanye nama-lifting lugs.

7. Yiziphi izitifiketi zekhwalithi ezinikezwayo lapho kuthunyelwa?

Sinikeza isitifiketi sokuhlola izinto ze-EN10204 3.1 (MTC); samukela ukuhlolwa kwangaphambi kokuthunyelwa okuvela ezinhlanganweni zezinkampani zangaphandle njenge-SGS/BV/TUV/DNV.
