1. Ts'ebetso ea Tlhahiso

Pipe ea Tšepe e se nang seamless

Liphaephe tse se nang mohele li etsoa kali-billet tsa tšepe tse tiileng. Sefuba se futhumatsoa le ho phunyeletsoa ho etsa phaephe e se nang letho. Phaephe e ntoo phuthoa kapa e hulwa ho ya ka boholo ba ho qetela ho sebediswamekhoa ea ho taka ka ho chesa kapa ka mokhoa o batang.

Mehato ea bohlokoa:

l Ho futhumatsa le ho hlahloba billet ea tšepe

l Ho phunya billet ho etsa khetla e se nang letho

l Ho phutholla kapa ho ntša metsi a chesang

l Cold drawing (boikhethelo bakeng sa lipeipi tse nepahetseng)

l Kalafo ea mocheso, ho otlolla le ho qeta

 

Liphaephe tse se nang mohele li na leha ho na moalo oa ho tjheseletsa, e fanang ka thepa e tšoanang ea mechini ho potoloha selikalikoe sohle.

Pipe ea Tšepe e Welded

Liphaephe tse tjheseditsweng di etswa ka ho phutholla dipoleiti tsa tshepe kapa dithapo ho etsa sebopeho sa cylindrical, ebe di tjheseletsa moroko ka ho sebedisaHo Wellisa ka Motlakase o Hanelang ho Sebetsa (ERW), Ho Wellisa ka Longitudinal, kapa ho Wellisa ka Spiral.

Mehato ea bohlokoa:

l Tšepe poleiti/strip theha

l Ho lokisa le ho tjheseletsa mahlakore

l Kalafo ea mocheso kapa phomolo ea khatello ea maikutlo (ha ho hlokahale)

l Ho otlolla, ho lekanya boholo le ho qeta

 

Leha liphaephe tse tjheseditsweng di na le moalo, mekgwa e tswetseng pele jwalo kaho taka ho batang holim'a mandrel (DOM)le ho qeta ka nepo ho fokotsa ponahalo ya moro le ho ntlafatsa ho tshwana ha sebopeho.

 

2. Thepa ea Mekaniki

Thepa	Pipe e se nang seamless	Pipe e nang le Welded	Lintlha
Matla a Tekanyo	Holimo	E mahareng ho isa ho e phahameng	Liphaephe tse se nang mohele li sebetsana le khatello e phahameng ka lebaka la sebopeho se tšoanang
Matla a tšepe	Holimo	E itekanetseng	Liphaephe tse se nang mohele li na le phallo e tšoanang ea lijo-thollo ho potoloha
Khanyetso ea Khatello	Holimo Haholo	E mahareng ho isa ho e phahameng	Liphaephe tse se nang mohele li khethoa bakeng sa litsamaiso tse nang le khatello e phahameng

Khanyetso ea Mokhathala	E babatsehang	Ho lokile	Liphaephe tse se nang mohele li mamella ho jarisoa ha potoloho hamolemo

Liphaephe tsa tšepe tse se nang seamless hangata lie matla le e tšoarellang haholoanyaneho feta liphaephe tse tjheseditsweng. Liphaephe tse tjheseditsweng hangata die theko e tlaase haholoanyane'me e ntse e loketse lits'ebetso tse ngata tsa indasteri le tsa meaho.

 

3. Ho nepahala ha litekanyo le mamello

Liphaephe tse se nang mohele, haholo-hololiphaephe tse se nang mohele tse huloang ka mokhoa o batang, tlhahisomamello e tiileng ea litekanyo, ho ba le oval e tlase, le ho otloloha ho hoholo. Sena se etsa hore e be tse loketseng bakeng salitsamaiso tsa mechine tse nepahetseng, liphaephe tse nang le khatello e phahameng, le liphaephe tsa boiler.

Paramethara	Pipe e se nang seamless	Pipe e nang le Welded	Lintlha
Mamello ea Bophara ba Kantle	± 0.05–0.10 mm	± 0.1–0.25 mm	Liphaephe tse se nang mohele li na le ho nepahala ho phahameng
Ho ba le ovalite	≤50% ea mamello ea OD	≤75% ea mamello ea OD	Sehokelo sa ho weld se ka ama ho chitja ha sona
Ho otloloha	≤1/1000	≤2/1000	Liphaephe tse se nang mohele li ka huleloa ho otloloha ka nepo
Botenya ba lebota	± 7.5%	± 10%	Liphaephe tse se nang mohele li fana ka botenya ba lebota bo lekanang
