Litekanyo tsa phala ea tšepe

Liphaephe tsa tšepeli arotsoe ka sebopeho sa karolo e tšekaletseng hore e be liphaephe tse chitja, tse sekoere, tse khutlonnetsepa, le tse bōpehileng ka ho khetheha; ka thepa e kenngoang liphaepheng tsa tšepe tsa sebopeho sa carbon, liphaephe tsa tšepe tsa sebopeho se tlaase, liphaephe tsa tšepe ea motsoako, le liphaephe tse kopaneng; le ka ho sebelisoa liphaepheng bakeng sa ho tsamaisa liphaephe, mehaho ea boenjiniere, lisebelisoa tsa mocheso, liindasteri tsa petrochemical, tlhahiso ea mechini, ho cheka jioloji, le lisebelisoa tsa khatello e phahameng. Ka ts'ebetso ea tlhahiso, li arotsoe ka liphaephe tsa tšepe tse se nang sekoli le liphaephe tsa tšepe tse kopantsoeng. Liphaephe tsa tšepe tse se nang sekoli li arotsoe ka mefuta e phuthoang ka ho chesa le e phuthoang ka ho bata (e huloang), ha liphaephe tsa tšepe tse kopantsoeng li arotsoe ka liphaephe tse phuthoang ka ho otloloha le liphaephe tse phuthoang ka ho potoloha.

 

Ho na le mekhoa e mengata ea ho emela liparamente tsa boholo ba phaephe. ​​Ka tlase ke litlhaloso tsa boholo ba phaephe bo sebelisoang hangata: NPS, DN, OD le Schedule.

(1) NPS (Boholo ba Phaephe bo Ikhethileng)

NPS ke tekanyetso ea Amerika Leboea bakeng sa liphaephe tse nang le khatello e phahameng/tlase le mocheso o phahameng/tlase. Ke nomoro e se nang tekanyo e sebelisoang ho bontša boholo ba phaephe. ​​Nomoro e latelang NPS e bontša boholo bo tloaelehileng ba phaephe.

NPS e thehiloe tsamaisong ea pele ea IPS (Tšepe ea Boholo ba Pipe). Sistimi ea IPS e thehiloe ho khetholla boholo ba liphaephe, ka litekanyo tse hlahisoang ka lisenthimithara tse emelang bophara bo ka hare bo hakanyetsoang. Mohlala, phaephe ea IPS ea 6" e bontša bophara bo ka hare bo haufi le lisenthimithara tse 6. Basebelisi ba qalile ho bitsa liphaephe liphaephe tsa 2-inch, 4-inch, kapa 6-inch.

 

(2) Bophara ba Lebitso DN (Bophara ba Lebitso)

Bophara ba Lebitso DN: Ketso e 'ngoe e emelang bophara ba lebitso (bore). E sebelisoa lits'ebetsong tsa liphaephe e le sesupo sa motsoako oa litlhaku le linomoro, se nang le litlhaku DN tse lateloang ke palo e felletseng e se nang tekanyo. Ho lokela ho hlokomeloa hore palo e felletseng ea DN ke palo e felletseng e chitja e loketseng bakeng sa merero ea litšupiso, e nang le kamano e hlephileng feela le litekanyo tsa 'nete tsa tlhahiso. Nomoro e latelang DN hangata e lekanngoa ka limilimithara (mm). Litekanyetsong tsa Sechaena, bophara ba liphaephe hangata bo hlalosoa e le DNXX, joalo ka DN50.

Bophara ba phaephe bo akaretsa bophara ba kantle (OD), bophara ba kahare (ID), le bophara ba nominal (DN/NPS). Bophara ba nominal (DN/NPS) ha bo tsamaisane le bophara ba 'nete ba kantle kapa ba kahare ba phaephe. ​​Nakong ea tlhahiso le ho kenya, bophara ba kantle bo tsamaellanang le botenya ba lebota bo tlameha ho khethoa ho latela litlhaloso tse tloaelehileng ho bala bophara ba kahare ba phaephe.

 

(3) Bophara ba Kantle (OD)

Bophara ba Kantle (OD): Letšoao la bophara ba kantle ke Φ, 'me le ka hlalosoa e le OD. Lefatšeng ka bophara, liphaephe tsa tšepe tse sebelisetsoang ho tsamaisa mokelikeli hangata li aroloa ka lihlopha tse peli tsa bophara ba kantle: Letoto la A (bophara bo boholo ba kantle, bo-imperial) le Letoto la B (bophara bo bonyenyane ba kantle, metric).

Ho na le letoto la bophara ba kantle ba liphaephe tsa tšepe lefatšeng ka bophara, joalo ka ISO (Mokhatlo oa Machaba oa Maemo a Tloaelehileng), JIS (Japane), DIN (Jeremane), le BS (UK).

 

(4) Kemiso ea Botenya ba Lebota la Phaephe

Ka Hlakubele 1927, Komiti ea Maemo a Amerika e ile ea etsa phuputso ea indasteri 'me ea hlahisa keketseho e nyane lipakeng tsa mekhahlelo e 'meli ea mantlha ea botenya ba lebota la liphaephe. ​​Sistimi ena e sebelisa SCH ho bontša botenya bo tloaelehileng ba liphaephe.
