Ake siqale sikhulume ngendawo yokuqala yepayipi lensimbi engagqwali: NO.1 Indawo ephathwa ngokushisa futhi ifakwe emanzini anosawoti ngemva kokugingqika okushisayo. Ivamise ukusetshenziselwa izinto ezigoqiwe ezibandayo, amathangi ezimboni, okokusebenza kwemboni yamakhemikhali, njll., ezinogqinsi olushubile olusuka ku-2.0MM-8.0MM. Indawo ebuthuntu: NO.2D Ngemva kokugoqeka okubandayo, ukwelashwa ngokushisa, nokucoshwa, into ithambile futhi ingaphezulu icwebezela ngesiliva. Isetshenziselwa ukucubungula izitembu ezijulile, njengezingxenye zemoto, amapayipi amanzi, njll.

Ukucutshungulwa kwendawo ehlukene kanye namazinga, izici ezihlukene, kanye nokusetshenziswa kuzoholela ezindleleni ezihlukene zokwelashwa, futhi ukunakwa nokuqapha okukhulu kusadingeka ekusetshenzisweni.

Ukwelashwa okungaphezulu kwamapayipi ensimbi okuvunguza ngokuyinhloko kusebenzisa amathuluzi afana namabhulashi ocingo ukupholisha ubuso bensimbi ukuze kususwe izikali ze-oxide ezixegekayo noma eziphakanyisiwe, ukugqwala, i-welding slag, njll. Ukususwa kokugqwala kwamathuluzi esandla kungafinyelela izinga le-Sa2, futhi ukususwa kokugqwala kwamathuluzi kagesi kungafinyelela izinga le-Sa3. Uma ubuso bensimbi bunamathele esikalini esiqinile se-iron oxide, umphumela wokukhipha ukugqwala wethuluzi ngeke ulunge futhi ukujula kwephethini yehange okudingekayo ekwakhiweni kwe-anti-corrosion ngeke kufinyelelwe.

I-Hairline: I-HL NO.4 iwumkhiqizo onephethini yokugaya ekhiqizwa ukugaya okuqhubekayo ngebhande lokupholisha losayizi wezinhlayiyana ezifanele (i-subdivision No. 150-320). Ikakhulukazi esetshenziselwa ukuhlobisa kwezakhiwo, amakheshi, iminyango yokwakha, amaphaneli, njll.

Indawo ekhanyayo: I-BA iwumkhiqizo otholwe ngokugoqeka okubandayo, i-annealing ekhanyayo, nokushelela. I-surface gloss inhle kakhulu futhi inokubonakala okuphezulu. Njengendawo yesibuko. Isetshenziswa ezintweni zasendlini, izibuko, izinto zasekhishini, izinto zokuhlobisa, njll.

Ngemva kokususwa kokugqwala kokufutha (ukuphonsa) kwamapayipi ensimbi ezungezayo, akukwazi nje ukwandisa umphumela wokukhangisa obonakalayo wendawo yepayipi kodwa futhi kuqinise umphumela wokunamathela komshini phakathi kongqimba olulwa nokugqwala kanye nendawo yepayipi. Ngakho-ke, ukususa ukugqwala kokufutha kuyindlela efanelekile yokususa ukugqwala kwepayipi lokuqeda ukugqwala. Ngokuvamile, ukususwa kokugqwala okudutshuliwe (isihlabathi) kusetshenziswa kakhulu ukwelapha amapayipi angaphakathi nangaphandle, futhi ukususwa kokugqwala kokudubula (isihlabathi) kusetshenziswa kakhulu ukwelapha amapayipi.
