TS EN 10253 e totobatsa litlhokahalo tsa lisebelisoa tsa tšepe tsa butt-welding, ho kenyeletsoa LR (Long Radius) le SR (Short Radius) 45 ° le 90 ° litsoe. Lisebelisoa tsena li sebelisetsoa ho hokahanya liphaephe tsa boholo bo fapaneng le ho fetola tsela ea ho phalla tsamaisong ea liphaephe. Mona ke selelekela sa lisebelisoa tsa EN 10253 butt-welding, ho kenyeletsoa LR/SR 45° le 90° elbows meahong e se nang moroallo le e cheselitsoeng:
1. Melao e Tloaelehileng:
TS EN 10253 butt-welding fittings e lumellana le litekanyetso tsa Europe bakeng sa lisebelisoa tsa tšepe tse sebelisoang lits'ebetsong tsa khatello.
- Lisebelisoa tsena li etselitsoe ho fihlela litlhoko tse ikhethileng tse amanang le sebopeho sa thepa, boholo, mamello le mekhoa ea tlhahlobo.
2. LR (Long Radius) Liqhomane:
- Li-elbows tsa LR li na le radius e kholoanyane, hangata makhetlo a 1.5 bophara ba phala, e fana ka tsela e phallang hantle le ho fokotsa khatello.
EN 10253 e totobatsa LR 45 ° le 90 ° elbows bakeng sa boholo bo fapaneng ba lipeipi le lihlopha tsa khatello.
- Li-elbows tsa LR li sebelisoa hangata lits'ebetsong moo tataiso ea phallo e fetohang butle-butle, joalo ka liindasteri tsa tšebetso.
3. SR (Short Radius) Liqhomane:
- Li-elbows tsa SR li na le radius e nyane, e fanang ka moralo o kopaneng haholoanyane o loketseng libaka tse thata kapa ha ho hlokahala phetoho e matla haholoanyane.
TS EN 10253 e kenyelletsa SR 45 ° le 90 ° elbows bakeng sa boholo bo fapaneng ba lipeipi le likhatello tsa khatello.
- Li-elbows tsa SR li sebelisoa lits'ebetsong moo mathata a sebaka kapa litlhoko tsa phallo li hlokang radius e kobehang.
4. Kaho e Seamless/Welded:
- TS EN 10253 li-welding tsa butt-welding li fumaneha ka har'a kaho e se nang moeli le e cheselitsoeng ho lumellana le litlhoko tse fapaneng tsa ts'ebeliso.
- Lisebelisoa tse se nang seamless li etsoa ka ho ntša pompo e se nang seam le ho e etsa hore e be sebopeho se lakatsehang, e fanang ka matla a holimo le bokaholimo bo boreleli ba kahare.
- Lisebelisoa tse cheselitsoeng li entsoe ka lipoleiti tsa tšepe tsa welding kapa likhoele ho etsa sebopeho se loketseng, ho fana ka litharollo tse bolokang chelete e ngata bakeng sa lits'ebetso tse seng bohlokoa haholo.
5. Litlhaloso tsa Thepa le Dimensional:
TS EN 10253 li-butt-welding fittings li fumaneha ka lisebelisoa tse fapaneng, ho kenyeletsoa tšepe ea khabone, tšepe e sa hloekang le tšepe ea alloy, ho fihlela litlhoko tsa liindasteri le tikoloho e fapaneng.
- Tekanyetso e hlakisa liparamente tsa boholo joalo ka boholo ba lebitso, botenya ba lebota, le li-angles ho netefatsa hore li tsamaellana le lipeipi le lisebelisoa tse ling tsa sistimi.
Ka bokhutšoanyane, lisebelisoa tsa EN 10253 butt-welding LR/SR 45°/90° ka har'a kaho e se nang moroallo kapa e cheselitsoeng ke likarolo tsa bohlokoa lits'ebetsong tsa lipeipi, tse fanang ka likhokahano tse tšepahalang le tse sa lutleng bakeng sa lits'ebetso tse fapaneng tsa indasteri. Lisebelisoa tsena li etselitsoe ho kopana le litekanyetso le litlhaloso tse thata ho netefatsa ts'ebetso e bolokehileng le e sebetsang ea liphaephe.
