Ukwehliswa Kwepayipi Lensimbi

Ipayipi lensimbiukwehlisa kubhekisela ekukhishweni kokugqwala, isikhumba esine-oxidized, ukungcola, njll. ebusweni bepayipi lensimbi ukuze kubuyiselwe ukucwebezela kwensimbi ebusweni bepayipi lensimbi ukuze kuqinisekiswe ukunamathela kanye nomthelela wokunamathela noma ukwelashwa kwe-anticorrosion okulandelayo. Ukunciphisa akukwazi nje ukwandisa impilo yesevisi yepayipi yensimbi, kodwa futhi kuthuthukise ukubukeka kwayo nokumelana nokugqwala.

Indima yokwehlisa ipayipi lensimbi
1. Thuthukisa umphumela we-anti-corrosion: Ngokususa ukugqwala, ukunamathela kwe-anti-corrosion coating kungandiswa, okwenza ipayipi lensimbi likwazi ukumelana nokugqwala.

2. Nweba impilo yesevisi: ukususa isikhumba esine-oxidized kanye nesendlalelo sokugqwala ebusweni bepayipi lensimbi kungasiza ekwandiseni impilo yesevisi yepayipi yensimbi.

3. Thuthukisa ukubukeka: ubuso bepayipi yensimbi ngemva kokwehliswa bushelelezi futhi buhle, ngokuhambisana nezidingo zokubukeka kokwakhiwa kwephrojekthi.

4. Ilungele ukucubungula okulandelayo: ngemuva kokwehliswa, kulungele ukwakhiwa kwe-coating kanye ne-anticorrosion layer ukuze kuthuthukiswe ukusebenza kahle kwesakhiwo kanye nekhwalithi.

Izindlela ezivamile zokwehlisa ipayipi lensimbi
1. Ukwehliswa kwesandla
Sebenzisa amabhulashi ocingo, i-sandpaper, ama-scrapers namanye amathuluzi okwenziwa ngesandla ukuze ususe ukugqwala.
Izinzuzo: izindleko eziphansi, ezifanele izindawo ezincane noma izingxenye zekhoneni.
Ukungalungi: ukusebenza kahle okuphansi, umphumela ongalingani wokwehlisa, awufanele ukwehliswa kwendawo enkulu.

2. Ukususwa kokugqwala ngomshini
Sebenzisa amathuluzi kagesi noma omoya, njengamasanders nama-grinders ukuze ususe ukugqwala.
Izinzuzo: ukusebenza kahle okuphezulu kunokwehliswa ngesandla, kulungele ukwehlisa indawo okumaphakathi.
Ukungalungi: kunzima ukufeza izinga eliphezulu lokwelashwa kwendawo, futhi umphumela uthintwa ngamathuluzi.

3. Ukususwa kokugqwala kwe-sandblasting (noma ukudubula ukususwa kokugqwala okuqhumayo)
Ukusetshenziswa komoya ocindezelwe kuzoba yi-abrasive (njengesihlabathi, i-steel shot) indiza yesivinini esiphezulu ebusweni bepayipi lensimbi ukuze kukhishwe ungqimba lokugqwala.
Izinzuzo: ukusebenza kahle okuphezulu, ikhwalithi enhle yokususa ukugqwala, ingafinyelela izinga eliphezulu lokuhlanzeka.
Ukungalungi: imishini ebizayo, inqubo idala uthuli nomsindo, ifanele ukusebenza kwendawo yangaphandle noma enkulu.

4. Ukususwa kokugqwala kwamakhemikhali
Sebenzisa izindlela zamakhemikhali ezifana nokukha amanzi ukuze ususe ungqimba lokugqwala ngesisombululo esimuncu.
Izinzuzo: ezifanele bobunjwa eziyinkimbinkimbi of steel pipe, kungaba ukususa ukugqwala obukhulu ungqimba.
Ukungalungi: ukugqwala, kudinga ukungathathi hlangothi, ukungabi nobungane emvelweni, izindleko zokwelashwa eziphezulu.

5. Ukwehla kwejethi yamanzi anomfutho ophezulu
Ukusebenzisa ijethi lamanzi elinomfutho ophezulu ukuze kuthinte ingaphezulu lepayipi lensimbi ukususa ungqimba lokugqwala, ukungcola nokunamathela okudala.
Izinzuzo: akukho uthuli, ukuvikelwa kwemvelo, kufanelekile ukwelashwa kwengqimba yokugqwala.
Ukubi: Ngemva kokukhipha ukugqwala, indawo engaphezulu iba manzi futhi idinga ukoma ngokushesha.

6. Laser Rust Ukususwa
Sebenzisa i-laser enamandla amakhulu ukuze usebenze phezu kwepayipi lensimbi ukuhwamulisa ungqimba lokugqwala.
Izinzuzo: ukuvikelwa kwemvelo, ukunemba okuphezulu, okulungele izimo ezifunwa kakhulu.
Ukungalungi: imishini ebizayo, efanele izidingo ezikhethekile.

Ukwelashwa kokugqwala kwangemva kokugqwala
Ngemva kokuphothulwa kokwehla kwepayipi lensimbi, indawo engaphezulu ivame ukuvezwa emoyeni futhi iphinde ifakwe i-oxidized, ngakho-ke ngokuvamile kuyadingeka ukwenza ukwelashwa okulandelwayo ngokushesha:
1. Faka okokuvikela ukubola: Gcoba okokuvikela ukubola noma upende ngaphezulu kwepayipi lensimbi ukuze uvimbele ukugqwala kabusha.

2. I-Hot-dip galvanizing: Thuthukisa ukumelana nokugqwala kwepayipi lensimbi ngokufaka uthayela, ofanele ukusetshenziswa isikhathi eside kwepayipi lensimbi.

3. Ukwelashwa kwe-passivation: Ukwelashwa kwe-passivation kuyenziwa ukwandisa ukumelana ne-oxidation.

4. Ukwelashwa kwe-Phosphating: Kusiza ukwandisa ukunamathela kwe-coating futhi kunikeze ukuvikelwa okwengeziwe kokugqwala.

Izindawo Zokufaka Isicelo
1. Ukwakhiwa: Kusetshenziselwa izakhiwo zokwakha,isikafula, njll. ukwandisa impilo yesevisi.

2. Ubunjiniyela be-Petrochemical: busetshenziselwa ukwehlisa amapayipi okuthutha nezinto zokusebenza ukuze kuthuthukiswe ukumelana nokugqwala.

3. ubunjiniyela bokuhlanza amanzi: busetshenziselwa amapayipi okudonsa amanzi kanye nendle ukuze kugwenywe ukugqwala.

4. Imboni yasolwandle: ukwelapha ukugqwala kanye nokwehliswa kwemikhumbi yemikhumbi namapayipi olwandle.

5. izindawo zokuthutha: njengamabhuloho, izinsimbi zokugada nezinye izinsiza zokususa ukugqwala kanye nokwelapha okuqeda ukugqwala.
