.Enqubweni yokwakha ipayipi likawoyela negesi elilwa nokugqwala,Ipayipi yensimbi ye-LSAW Ukwelashwa kwe-anti-corrosion surface ukunquma impilo yesinye sezici ezibalulekile, ungqimba lwepayipi lensimbi le-LSAW lokulwa nokugqwala nokuthi ingabe inhlanganisela yesisekelo esiqinile.Ukutadisha izinhlangano professional, ngaphezu ukuphila enamathela kuncike ohlotsheni enamathela, izinga Coating kanye nokwakhiwa kwezici zemvelo, LSAW steel ipayipi enamathela ukwelashwa surface yokuphila-isikhathi mayelana 50%, Ngakho-ke, kufanele ngokuqinile ku ngokuhambisana nokunameka okujwayelekile okungaphezulu kwezidingo zepayipi lensimbi ye-LSAW, ukuthuthuka okuqhubekayo kwendlela yokwelapha engaphezulu komthungo wensimbi,Ipayipi lensimbi ye-LSAW yizindlela ezilandelayo ikakhulukazi ngaphezu kwezigaba zokufekethiswa:

I-1, ukusetshenziswa kokuhlanza i-solvent, i-emulsion yokuhlanza ingaphezulu lensimbi, ukuze kuzuzwe ukususwa kwamafutha, amafutha, uthuli, izinto zokugcoba nezinto ezifanayo, kodwa ayikwazi ukususa ukugqwala kwensimbi, i-oxide, i-welding flux, njll. ngakho-ke imisebenzi emelene nohulumeni isebenza njengesengezo kuphela.

2, ukuqoqa

Ngokuvamile izindlela ezimbili ezisetshenziselwa ukwenza inqubo yokukhetha amakhemikhali kanye ne-electrolytic, ukugqwala kwepayipi kusetshenziswa kuphela i-chemical etching, ukususa i-oxidation, ukugqwala, okokumboza amadala, ngezinye izikhathi okusetshenziselwa ukuqhunyiswa kwesihlabathi ngemva kokucubungula kabusha.Nakuba ukuhlanzwa kwamakhemikhali kungafinyelela ukuhlanzeka okuthile kwendawo kanye nokuqina, kodwa ukukhanya kwe-anchorpattern, futhi kulula ukungcolisa indawo ezungezile.

3, ukugqwala kwamathuluzi

Ikakhulukazi sebenzisa ibhulashi locingo namanye amathuluzi endaweni yensimbi epholishiwe, ingasusa i-oxide exekethile, ukugqwala, i-welding slag.Ukugqwala kwamathuluzi esandla kungafinyelela amathuluzi wamandla ebanga le-Sa2 agxume akhuphukele phezulu ku-Sa3, uma enamathiselwe esikalini sensimbi esiqinile se-oxide, ukugqwala kwamathuluzi akwenelisi,Finyelela ezidingweni zokwakhiwa kokugqwala kwephethini lehange.

4, fafaza ukugqwala kokugqwala ngesifutho esiqhutshwa yinjini egijima ngesivinini esikhulu esiphenduphendukayo, ukuze ukudubula kwensimbi, inhlaka, izingxenye zocingo, amaminerali kanye namanye amandla aqinile acibilikayo aphakathi nendawo kumapayipi ensimbi omthungo oqondile ngaphansi kobuso bomuthi wokufafaza. , hhayi kuphela Ungakwazi ukususa ngokuphelele ama-oxides, ukugqwala nokungcola kanye nepayipi lensimbi ye-LSAW emthelela omkhulu we-abrasive kanye nendima yokungqubuzana, kodwa futhi ukufeza ubulukhuni obufanayo obudingekayo.Futha ukugqwala, awukwazi nje ukwandisa indima ye-adsorption tube surface, futhi ingathuthukisa ungqimba lokugqwala kanye nokunamathela komshini kwendawo ye-tube.Ngakho-ke, i-jet rust iyindlela ekahle yokugqwala kwamapayipi.Ngokuvamile, ukugqwala okuvuza okudutshulwa ngaphakathi kweshubhu kusetshenziselwa ikakhulukazi ukwelashwa okungaphezulu, ukudubula okuqhumisa amapayipi ensimbi othungelwano oluqondile ikakhulukazi asetshenziselwa ukwelapha ngaphandle. ipayipi lensimbi yomthungo ukuya ekulimaleni kwesibili, ngaphezu kwamapayipi ensimbi omthungo oqondile ngokusebenzisa ukufekethiswa, ukubukeka kwemikhiqizo efekethisiwe futhi ngaphezu kwalokho izoba bushelelezi kakhulu kunangaphambili, kunamapayipi ensimbi omthungo oqondile ahlotshiswe embonini yensimbi kuyindlela esetshenziswa njalo.
