1. Khetha mokhoa o nepahetseng oa ho hokahanya ho ea ka bophara le maemo a itseng a phala.
① Welding: Ho kenya ho tla qala ka nako e nepahetseng ho latela tsoelo-pele ea sebaka sa marang-rang. Lokisa li-brackets esale pele, taka setšoantšo ho latela boholo ba 'nete,' me u lokise lipeipi ho fokotsa li-fittings le ho kenya manonyeletso a shoeleng liphaepheng. Liphaephe li lokela ho otlolloa esale pele, 'me ho buleha ho lokela ho koaloa ha ho kenngoa ho sitisoa. Haeba moralo o hloka casing, casing e lokela ho eketsoa nakong ea ts'ebetso ea ho kenya. Ho ea ka litlhoko tsa moralo le lisebelisoa, boloka sebopeho, se tiise, 'me u itokisetse mohato o latelang oa tlhahlobo. Mosebetsi oa khatello ea maikutlo.
② Khokahano e nang le likhoele: likhoele tsa liphaephe li sebetsoa ka mochini oa khoele. Ho roala ka letsoho ho ka sebelisoa bakeng sa liphaephe tsa 1/2″-3/4″. Ka mor'a ho khoasolla, phaephe e bulehileng e lokela ho hloekisoa le ho bolokoa e boreleli. Likhoele tse robehileng le likhoele tse sieo ha lia lokela ho feta 10% ea palo eohle ea likhoele. Khokahano e lokela ho tiea, ho se be le khoele e pepenene motsong. Khoele e pepesitsoeng motsong ha ea lokela ho ba li-buckles tse fetang 2-3, 'me karolo e hlakileng ea khoele e lokela ho ba hantle khahlanong le kutu.
③ Khokahano ea Flange: Lihokelo tsa flange lia hlokahala likhokahanong lipakeng tsa liphaephe le li-valve. Li-flanges li ka aroloa ka li-flange tsa welding tse bataletseng, li-flange tsa welding, joalo-joalo. Li-flange li entsoe ka lihlahisoa tse felileng. Mohala o bohareng oa flange le phala li na le perpendicular, 'me ho buleha ha phala ha hoa lokela ho hlahella ho tloha holimo ho tiisoa ha flange. Liboutu tse tlamang flange li lokela ho hlatsuoa ka oli e tlotsang pele li sebelisoa. Li lokela ho tšeloa ka symmetrically le ho tiisoa ka makhetlo a 2-3. Bolelele bo pepesitsoeng ba screw ha boa lokela ho feta 1/2 ea bophara ba screw. Linate li lokela ho ba ka lehlakoreng le le leng. Flange gasket ha ea lokela ho hlahella ka har'a phala. , ha hoa tlameha hore ho be le letlapa le sekametseng kapa li-pads tse fetang tse peli bohareng ba flange.

2. Anti-corrosion: Liphaephe tse pepesitsoeng tsa masenke li lokela ho penta ka lijase tse peli tsa phofo ea silevera, 'me liphaephe tse patiloeng tsa masenke li lokela ho penta ka liaparo tse peli tsa asphalt.

3. Pele o beha le ho kenya liphaephe, litšila tse ka hare li lokela ho hloekisoa ho thibela li-welding slag le litšila tse ling hore li se ke tsa oela ka har'a liphaephe. Liphaephe tse kentsoeng li tlameha ho tlamisoa le ho koaloa.

4. Ka mor'a hore mohaho o phethoe, tsamaiso eohle e lokela ho ba le teko ea khatello ea hydrostatic. Khatello ea karolo ea phepelo ea metsi ea malapeng ke 0.6mpa. Haeba khatello e theoha e sa fete 20kpa nakong ea metsotso e mehlano, e ea tšoaneleha.
