Chofoza Inkinobho Kwesokudla
1. Izisekelo Zodonga: Izisekelo zodonga olungaphansi kwesakhiwo sezakhiwo eziphakeme, zefektri, zendlu yokugcina impahla, zezentengiselwano noma zezindlu zokuhlala. Izisekelo zenqwaba zifanele zonke izinhlobo zezakhiwo.
2. Izisekelo Zezinqwaba Zebhuloho: Izisekelo ezithwala imithwalo zamabhuloho omgwaqo omkhulu, wesitimela kanye nowemigwaqo yasemadolobheni. Izisekelo zomfula womoba, i-lacustrine, kanye nezinqwaba zasolwandle.
3. Ukwakhiwa Kwechweba: Izisekelo ezithwala imithwalo zezindawo zokubeka imithwalo, izindawo zokubeka imikhumbi, kanye namapulatifomu okubeka imithwalo. Imishini esindayo kanye nemishini yokuphatha imithwalo yemikhumbi.
4. Ubunjiniyela Basemanzini kanye Nemiklamo Yamandla Omoya Olwandle: Izisekelo zama-turbine omoya asogwini lolwandle. Umklamo Wokusekela Amapulatifomu Asogwini Lolwandle, Amapayipi Asogwini Lolwandle, Amadonga Olwandle, njll. Ukumelana namagagasi, ukumelana namagagasi kanye nokumelana nokugqwala kolwandle.
5. Ubunjiniyela Bokwakha Obukhulu, Izinqwaba Ezinkulu:Umsebenzi omkhulu wobunjiniyela bezokwakha (njengamadamu, iziteshi zangaphansi komhlaba, kanye nemigudu) odinga izisekelo ezijulile kusetshenziswa izinqwaba ezinkulu. Ukusekelwa kwemithwalo yezimboni kanye nemishini kanye nezakhiwo.
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
1. Ukupakisha:Izintambo zensimbi ukuze kube lula ukuziphatha. Amabhulokhi okhuni noma i-dunnage kufakwa phakathi kwezinqwaba ukuze kuvikelwe ekulimaleni ngesikhathi sokuthuthwa. Ukwelashwa kwendawo (ongakukhetha): Upende omnyama, uwoyela wokugqwala, i-plastic film roll. Izinqwaba ze-hot dip galvanized nazo zingambozwa ngefilimu yokuvikela indawo okwesikhashana. Singaphinde sinikeze ukupakishwa okwenziwe ngokwezifiso.
2. Ukulethwa:Ubude obujwayelekile besitokwe: 6m, 12m. Ubude obujwayelekile obuhambisana nephrojekthi yakho. Ifanelekela ukuthuthwa olwandle kanye nojantshi kanye nomgwaqo. Isikhathi sokukhiqiza ngokuvamile siyizinsuku eziyi-15-30 ngemuva kokuthola inkokhelo, ukulethwa kusenesikhathi ngokwenani kanye nencazelo. Ifanele ukuthunyelwa kwamanye amazwe emhlabeni wonke ngemibhalo ephelele (isitifiketi sokuhlola, uhlu lokupakisha, i-bill of lading).
Izindlela Zokuvimbela:
1. I-crane noma i-forklift enezinsika noma izicathulo ze-slingshoes kufanele isetshenziswe ukugwema ukuguquka kwepayipi ku-Handing Peoperties.
2. Gcina indawo epholile, eyomile futhi enomoya ukuze igcinwe, kungenjalo kuzovela ukugqwala ngaphambi kokufakwa. Kumaphasela amakhulu/akhuluphele kakhulu, sicela ulandele umthethonqubo wokuthumela wendawo ngokuqinile.
1. Iyini inqwaba yamapayipi ensimbi e-ASTM A252 Grade 3?
Izinqwaba zamapayipi ensimbi ebanga lesi-3 e-ASTM A252amapayipi ensimbi ahlanganisiwe asetshenziswa njengesisekelo esijulile ngaphansi kwezakhiwo, amabhuloho, amachweba, kanye nobunjiniyela basogwini lolwandle. Kunezinqubo ezimbili zokushisela zala mapayipi: ipayipi lokushisela le-arc elingaphansi komhlaba eliyi-helical (SSAW) noma ipayipi lokushisela le-arc elingaphansi komhlaba eliyi-longitudinal (LSAW/EFW).
2. Yiziphi izilinganiso nobude obutholakalayo?
Ububanzi bangaphandle: 219 mm - 3000 mm (usayizi we-XXL/ububanzi obukhulu buyatholakala) Ubukhulu bodonga: 6-40 mm. Ubude besitoko obujwayelekile bungamamitha ayi-6 namamitha ayi-12, futhi ubude obukhethekile bunganikezwa uma buceliwe.
3. Yiziphi izindinganiso zezinto kanye nezakhiwo zemishini?
Izinga Lezinto Ezibalulekile: I-ASTM A252 Ibanga 3
Amandla Okukhiqiza: ≥345 MPa
Amandla okudonsa: 455~620 MPa
Ukwandiswa: ≥20%%
4. Ngingayithola yini isitifiketi sekhwalithi kanye nemibiko yokuhlola?
Yebo zonke izinqwaba zamapayipi ensimbi ziqinisekiswe yi-ISO 9001. Yonke imibhalo edingekayo kufaka phakathi imibiko evela eceleni evela ku-SGS, BV noma kwenye inhlangano eyaziwayo.
5. Amapayipi ensimbi apakishwa kanjani?
Ibopha izinqwaba zamapayipi ensimbi ngebhandeji lensimbi bese ihlukaniswa ngebhlokhi lokhuni ngaphandle kokulimala. Ukuvikelwa/ukugoqa noma/kanye nokwelashwa kwendawo okukhulunywe ngayo ngenhla kuyanconywa ngokuya ngephakheji yokuthumela. Ukupakishwa okwenziwe ngokwezifiso kuyatholakala.
6. Singakanani isikhathi sokulethwa?
Isikhathi sokuthumela: Izinsuku eziyi-15-30 ngemuva kokuqinisekiswa kwe-oda (kuya ngobuningi, imininingwane kanye nendawo oya kuyo).
7. Kungenzeka yini ukwenza osayizi ngokwezifiso?
Yebo, ububanzi, ukujiya kodonga kungenziwa ngezifiso ngokuya ngezidingo ezithile zamakhasimende.
