6. 2. Eccentric Reducer:
7. - Eccentric Reducer ke mochini o kenyang butt-welding moo moeli o bohareng oa ho kena le ho tsoa o fapana, ho theha offset ho fetola tsela ea phallo kapa ho hokahanya liphaephe tsa bophahamo bo fapaneng.
8. TS EN 10253 e fana ka litekanyetso tsa Eccentric Reducers, ho kenyeletsoa kaho, khetho ea thepa, le mamello ea boholo, bakeng sa taolo e sebetsang ea phallo ea liphaephe.

10. 3. Thepa le Kaho:
11. TS EN 10253 butt-welding fittings bakeng sa Concentric and Eccentric Reducers e fumaneha ka lisebelisoa tse fapaneng, ho kenyeletsoa tšepe ea khabone, tšepe e sa hloekang le tšepe ea alloy, ho lumellana le litlhoko tse fapaneng tsa khatello le mocheso.
12. - Lisebelisoa tsena li entsoe ka mekhoa ea kaho e tloaelehileng ho netefatsa khokahano e matla, e sa lutleng lipakeng tsa liphaephe tsa li-diameter tse fapaneng.
13.  
14. 4. Kopo le Melemo:
15. - Concentric Reducers e sebelisoa mecheng ea liphaephe ho fokotsa sebaka sa phallo lipakeng tsa liphaephe ha ho ntse ho bolokoa lebelo la mokelikeli o sa khaotseng, o loketseng maemo ao sebaka e seng tšitiso.
16. - Li-Eccentric Reducers li loketse lits'ebetso moo liphaephe li hlokang ho lokisoa ho ea holimo kapa ho thibela lipokotho tsa moea tsamaisong ka ho lumella mokelikeli hore o tsoe ka katleho.
17. - Mefuta ena ka bobeli ea lisebelisoa e bapala karolo ea bohlokoa lits'ebetsong tsa hydraulic, liindasteri tsa oli le khase, lifeme tsa petrochemical, lisebelisoa tsa phepelo ea motlakase le lifeme tsa ho hloekisa metsi.

19. 5. Ho kenya le ho Welding:
20. - Ho tsamaisana hantle, mekhoa ea ho cheselletsa, le tlhahlobo ea khatello ke tsa bohlokoa nakong ea ho kenya Concentric le Eccentric Reducers ho netefatsa khokahanyo e sireletsehileng le e ka tšeptjoang pakeng tsa liphaephe.
21. - Butt-welding ke mokhoa o tloaelehileng oa ho kenya lisebelisoa tsena tse fokotsang, ho fana ka motsoako o matla o ka mamellang khatello, liphetoho tsa mocheso, le ho phalla ha metsi ka har'a tsamaiso ea liphaephe.
22.  
23. Ka bokhutšoanyane, lisebelisoa tsa EN 10253 butt-welding bakeng sa Concentric le Eccentric Reducers ke likarolo tsa bohlokoa tse thusang phetoho ea phallo le ho hokahanya ha lipeipi lits'ebetsong tse fapaneng tsa indasteri. Lisebelisoa tsena li khomarela litekanyetso tse thata ho netefatsa hore lia lumellana, lia tšepahala, 'me li sebetsa hantle lits'ebetsong tsa lipeipi ho pholletsa le liindasteri le lits'ebetso tse fapaneng.
