J-VALVES Khetho ea Mekhoa ea Khokahano ea Balofo ea Heke

I. Tlhahlobo e Felletseng

1.Flange Connection
· le menyetla:

Likhokahano tse emeng tse nang le maemo a matla, tse tšehetsang mefuta e mengata ea flange joalo ka RF le RTJ.

Moralo o sa khoneheng, o nolofalletsang phetoho ea li-valve kapa katoloso ea sistimi.
· Mefokolo:

Liboutu li atisa ho hlephisa le ho lutla ha mocheso o le holimo (>350°C).

E na le sebaka se seholo 'me ha ea tšoanela maemo a ho kenya compact.
· Maemo a sebetsang:

Litsamaiso tse mahareng le tse phahameng tsa khatello tse joalo ka petrochemical le LNG stor

2. Khokahano ea Khoele
· Melemo:

Ho kenya ka potlako ntle le tlhokahalo ea lisebelisoa tsa setsebi, tse loketseng liphaephe tse ka tlaase ho DN50.

Theko e tlase ebile e sebelisoa haholo lits'ebetsong tse futhumatsang metsi a khatello e tlase.
· Mefokolo:

Likhoele li lokoloha habonolo ka lebaka la ho thothomela 'me li hloka tlhahlobo ea khafetsa ea ts'ebetso ea ho tiisa.

Ha e loketse mocheso o phahameng, khatello e phahameng kapa mecha ea litaba e senyang.
Maemo a Sebetsang: Litikoloho tse nang le khatello e tlase joalo ka phepelo ea metsi ka tlung le li-interface gauge tsa khatello.

3. Welded Connection
· Melemo:

Ha ho kotsi ea ho lutla, e loketseng mocheso o feteletseng / likhatello.

Sebopeho se kopaneng ntle le boima ba lihokelo tse eketsehileng.
· Mefokolo:

E hloka li-welders tsa profeshenale, 'me ho qhaqha ho hloka ho seha liphaephe.

Li-weld seams li ka 'na tsa hlōleha ka lebaka la ho bola ha mahareng kapa mokhathala oa vibrate.
Maemo a sebetsang: 

Litsamaiso tsa nako e telele tsa meroalo e phahameng joalo ka lifeme tsa matla a nyutlelie le likarolo tsa ho phatloha ha ethylene.

II. Litlhahiso tsa Khetho

1. Etella pele khokahano ea flange: Bakeng sa liphaephe tse mahareng le tse phahameng tse hlokang ho lokisoa khafetsa kapa katoloso ea sistimi (joalo ka li-refineries).

2. Etela pele ho khokahanyo ea khoele: Bakeng sa maemo a tlase, a bophara bo nyane le a sa sisinyeheng (joalo ka phepelo ea metsi ka lapeng).

3. Etelletsa pele ho khokahanyo ea li-welded: Bakeng sa maemo a thata a ho sebetsa a nang le mocheso o phahameng haholo/khatello e phahameng le litlhoko tsa ho tiisa ka ho sa feleng (joaloka litsamaiso tsa ho pholisa reactor ea nyutlelie).

III. Mehato ya tlhokomelo

1. Khokahano ea Flange: Ha u khetha mefuta ea RF kapa RTJ flange, hoa hlokahala ho tsamaisana le tekanyo ea khatello ea liphaephe.

2. Khokahano ea Khoele: Etsa bonnete ba hore o sebelisa likhoele tse tloaelehileng tsa NPT le ho thatela theipi e tiisang.·

3. Khokahanyo ea Welded: Tlhahlobo ea seam ea weld e lokela ho etsoa ho latela litlhaloso tsa ASME B31.3.
