Isicelo Esiyinhloko

1. Izisekelo Zodonga Olungaphansi:Izisekelo ezijulile zezakhiwo ezinde, amafektri, izindawo zokugcina impahla, izakhiwo zebhizinisi nezindawo zokuhlala. Izisekelo zenqwaba (ezifanele zonke izinhlobo zezakhiwo).

2. Izisekelo Zezinqwaba Zebhuloho:Izisekelo ezithwala imithwalo zamabhuloho omgwaqo omkhulu, amabhuloho esitimela, kanye nemigwaqo yasemadolobheni. Izisekelo zenqwaba zamabhuloho omfula, echibini, kanye nawawela ulwandle.

3. Ukwakhiwa Kwechweba:Izisekelo ezithwala imithwalo zezindawo zokubeka imithwalo, izindawo zokubeka imikhumbi, kanye namapulatifomu okubeka imithwalo. Imishini esindayo kanye nezindawo zokuphatha imithwalo yemithwalo yemikhumbi.

4. Amaphrojekthi Obunjiniyela Bomoya Olwandle kanye Nomoya Osebenza Ngaphandle:Izisekelo zama-turbine omoya asogwini lolwandle. Umklamo wokusekela amapulatifomu asogwini lolwandle, amapayipi asogwini lolwandle, izindonga zasolwandle, njll. Ukumelana namaza, ukumelana namaza, kanye nokumelana nokugqwala kolwandle.

5. Ubunjiniyela Bokwakha Obukhulu:Izisekelo ezijulile ezinezinqwaba ezinkulu zamaphrojekthi amakhulu obunjiniyela bezakhiwo (njengamadamu, iziteshi zangaphansi komhlaba, kanye nemigudu). Ukusekelwa kwemishini yezimboni kanye nemithwalo yezakhiwo.

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

Ukupakisha Nokulethwa

1. Ukupakisha:Ibhande lensimbi ukuze kube lula ukuliphatha.
Amabhulokhi ezinkuni noma i-dunnage abekwa phakathi kwezinqwaba ukuvimbela umonakalo ngesikhathi sokuthuthwa.
Ukuvikelwa kobuso (ongakukhetha): Upende omnyama, uwoyela wokuvimbela ukugqwala, noma imiqulu yefilimu yepulasitiki.
Izinqwaba ze-galvanized ezicwiliswa ngokushisa zingase zibe nefilimu yokuvikela yesikhashana ukuvimbela ukuklwebheka kobuso.
Ukupakishwa ngokwezifiso kuyatholakala uma ucela.

2. Ukulethwa:Ubude besitoko obujwayelekile: amamitha ayi-6 namamitha ayi-12. Ubude obungokwezifiso buyatholakala ukuze kuhlangatshezwane nezidingo zephrojekthi yakho.
Ilungele ezokuthutha olwandle, isitimela, noma umgwaqo.
Isikhathi sokulethwa ngokuvamile siyizinsuku eziyi-15-30 ngemuva kokuqinisekiswa kwenkokhelo, kuye ngobuningi kanye nezincazelo.
Ifanele ukuthunyelwa kwamanye amazwe emhlabeni jikelele, kanye neqoqo eliphelele lamadokhumenti (isitifiketi sokuhlola, uhlu lokupakisha, i-bill of lading).

3. Ukuphatha Izinyathelo Zokuqapha:Sebenzisa i-crane noma i-forklift efakwe izihlilingi noma izihlilingi ukuvimbela ukuguguleka kwepayipi.
Gcina endaweni epholile, eyomile, nenomoya omuhle ukuze uvimbele ukugqwala ngaphambi kokufakwa.
Uma uthumela impahla enkulu kakhulu/isisindo esikhulu, sicela uhambisane nemithethonqubo yokuthumela impahla yendawo.

Imibuzo Evame Ukubuzwa

1. KuyiniIzinqwaba zamapayipi ensimbi e-ASTM A252 Grade 3?
Amapayipi ensimbi e-ASTM A252 ebanga lesi-3 ahlanganiswe ngamapayipi ensimbi akhiwe ngesakhiwo ukuze asetshenziswe njengesisekelo esijulile ngaphansi kwezakhiwo, amabhuloho, amachweba, kanye nobunjiniyela basogwini. 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.
