Ukuqedwa Komphezulu

Iqembu Lensimbi Yasebukhosiniinikeza uhla oluphelele lwezindlela zokwelapha ubuso ezilwa nokugqwala ezenzelwe wenaIzinqwaba zamapayipi ensimbi e-ASTM A500, ehlanganisa ukusetshenziswa okuvamile kwangaphakathi nezwe kanye nezindawo ezingcolisayo zasolwandle, zasogwini kanye nezangaphansi komhlaba. Sinikeza izinketho zokumboza eziguquguqukayo ukuze zivumelane nesabelomali sephrojekthi esihlukene kanye nezidingo zesikhathi senkonzo.

1. Indawo Emnyama Yensimbi
Ukuqeda kwensimbi emnyama yokuqala akunawo upende owengeziwe, ohambisana nokwelashwa okuvamile kokulwa nokugqwala okugcotshwe ngamafutha. Kuyindlela engabizi kakhulu, efaneleka kahle kumaphrojekthi okwakha angaphakathi ezweni, imisebenzi yesakhiwo sangaphakathi kanye nezingxenye ezidinga ukusika okwesibili, ukushisela kanye nokucubungula kabusha. Lokhu kuqeda kunikeza ukusebenza okuyisisekelo okuzinzile futhi kuhlangabezana nezidingo zesikhashana zokulwa nokugqwala kanye nokusetshenziswa kwesakhiwo kobunjiniyela besisekelo obuvamile.

2. Isembozo se-Fusion Bonded Epoxy (FBE)
Isembozo se-FBE siyindlela yokuvikela esebenza kahle kakhulu enesendlalelo esisodwa esetshenziswa ngobungcweti ezindaweni zamapayipi ensimbi. Sinokuqina kwamakhemikhali okuvelele, simelana ngempumelelo nokuguguleka okuvela ku-asidi, i-alkali, usawoti kanye nezinhlobo ezahlukene zamakhemikhali. Ngamandla okubopha aqinile kanye nokumelana okuhle kakhulu kokuguguleka, lesi sembozo sinikeza isivikelo sokulwa nokugqwala esiqinile isikhathi eside, esifanele izindawo zezimboni, izimo zokuthintana kwamakhemikhali kanye nezakhiwo zesisekelo ezingaphansi komhlaba ezinezidingo eziqinile zokuqina.

3. Isimbozo Sokulwa Nokugqwala Esinezingqimba Eziningi ze-3PE
Isembozo esihlanganisiwe esinezingqimba ezintathu ze-3PE siyisisombululo esijwayelekile sokulwa nokugqwala esinzima sezimo ezinzima zobunjiniyela, esakhiwe uhlelo lobuchwepheshe lwesakhiwo olunezingqimba ezintathu: isendlalelo se-epoxy primer, isendlalelo esinamathelayo esiphakathi kanye nesendlalelo sangaphandle sokuvikela se-polyethylene. Umklamo wesakhiwo ohlanganisiwe ufeza inhlanganisela ephelele yokumelana nokugqwala kwamakhemikhali, ukumelana nomthelela womshini kanye nokusebenza kokuvikela okungangeni manzi.
Ngenxa yokuzivumelanisa nezimo kwayo okuphezulu ezindaweni ezibucayi, uhlelo lokumboza lwe-3PE lusetshenziswa kabanzi kwezobunjiniyela basogwini, izakhiwo zasolwandle, amaphrojekthi esisekelo sasogwini, kanye nemisebenzi yenqwaba yamapayipi angcwatshwe enezidingo eziphezulu zokulwa nokugqwala nokuphila isikhathi eside.

Isicelo Esiyinhloko

1. Izisekelo Zodonga Olungaphansi:Ukwakhiwa ngaphansi komhlaba kwezakhiwo ezinde, amafektri, izindawo zokugcina impahla, izakhiwo zebhizinisi nezindawo zokuhlala. Izisekelo zenqwaba (zonke izinhlobo zokwakha izakhiwo).

2. Izisekelo Zezinqwaba Zebhuloho:Izisekelo zokuthwala amabhuloho omgwaqo omkhulu, amabhuloho kaloliwe, kanye nemigwaqo yasemadolobheni. Izisekelo zenqwaba yamabhuloho omfula, echibini kanye nolwandle.

3. Ukwakhiwa Kwechweba:Isisekelo sokuthwala imithwalo sezindawo zokubeka imithwalo, amayadi emikhumbi kanye namapuleti edokhi. Imishini esindayo kanye nezinsizakalo zokulethwa kwemithwalo edokhini.

4. Amaphrojekthi Obunjiniyela Bamandla Omoya Nasemanzini Angaphandle:Izisekelo zama-turbine omoya asogwini lolwandle. Umklamo wokusekela amapulatifomu asogwini lolwandle, amapayipi asogwini lolwandle, amapayipi asogwini lolwandle, izindonga zasolwandle kanye nokho Emakhaya okuhlala Ukumelana namaza, ukumelana namaza, kanye nokugqwala kolwandle.

5. Ubunjiniyela Bokwakha Obukhulu:Izisekelo ezisindayo ezinezinqwaba ezibanzi zemisebenzi yobunjiniyela bezakhiwo ezinkulu (amadamu, iziteshi zesitimela, 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:Izintambo zensimbi zokuphatha kalula Amabhulokhi enkuni noma i-dunnage zifakwa phakathi kwezinqwaba ukuvimbela ukushintsha kwezitho ngesikhathi sokuthunyelwa. Ukwelashwa kwendawo (ongakukhetha): Ukupenda okumnyama, uwoyela wokuvimbela ukugqwala, ifilimu yepulasitiki. Izinqwaba ze-galvanized zingasongwa ngefilimu yepulasitiki evikelayo yesikhashana ukuvimbela ukuklwebheka indawo. Kukhona ukupakisha okwenziwe ngokwezifiso.

2 Ulwazi Lokulethwa:Ubude Obujwayelekile Obukhona Esitokweni: 6m, 12m. Ubude: obujwayelekile nobenziwe ngokwezifiso. Ziza Nesitimela Sasolwandle Nokusebenza Komgwaqo. Zilungele ukuthuthwa ngomkhumbi, ngesitimela noma ngomgwaqo, futhi ziqinile ngokwanele ekusetshenzisweni komgwaqo. Isikhathi sokulethwa siyizinsuku eziyi-15-30 ngemuva kokuthola inkokhelo, kuye ngobuningi kanye nencazelo. Zisebenza ekuthunyelweni kwamanye amazwe emhlabeni jikelele, kanye nedokhumenti ephelele (Isitifiketi Sokuhlola, Uhlu Lokupakisha, I-Bill of Lading).

3 Izinyathelo zokuphepha zokuphatha:Ungasebenzisi izihlilingi noma izingwegwe ezingenamaphedi ukuze uthintane ngqo nobuso bepayipi okungase kubangele ukuguguleka kwepayipi. Gcina endaweni epholile, eyomile futhi enomoya omuhle. Ukuze ugweme ukugqwala ngaphambi kokufakwa. Imithwalo emikhulu kakhulu futhi ekhuluphele kumele ihambisane nemithetho yokuthumela yendawo.
