Litlhoko tsa tekheniki le mekhoa ea ho sebetsana le liphaephe tse otlolohileng tsa seam seam

Litlhoko tsa tekheniki bakeng sa liphaephe tse otlolohileng tsa seam: Litlhoko tsa tekheniki le tlhahlobo ea liphaephe tse otlolohileng tsa seam tse otlolohileng li ipapisitse le maemo a GB3092 a "Welded Steel Pipes for Low-Pressure Fluid Transport". Bophahamo ba lebitso la phala e cheselitsoeng ke 6 ~ 150mm, botenya ba lebota bo ka thoeng ke 2.0 ~ 6.0mm, 'me bolelele ba phala e cheselitsoeng Hangata ke limithara tse 4 ~ 10, e ka romelloa ho tloha fekthering ka bolelele bo tsitsitseng kapa bolelele bo bongata. Bokaholimo ba phala ea tšepe e lokela ho ba boreleli, 'me liphoso tse kang ho phutha, mapetsong, delamination, le welding lap ha lia lumelloa. Bokaholimo ba phala ea tšepe bo lumelloa ho ba le mefokolo e nyane joalo ka mengopo, likhopo, li-weld dislocations, cheso, le maqeba a sa feteng ho kheloha ho hotle ha botenya ba lerako. Botenya ba lerako ka weld le ho ba teng ha ka hare weld mekoallo lumelloa. Lipeipi tsa tšepe tse cheselitsoeng li lokela ho etsa liteko tsa ts'ebetso ea mochini, liteko tsa ho batalatsa, le liteko tsa katoloso, 'me li tlameha ho fihlela litlhoko tse boletsoeng maemong.

E lumelloa ho sebelisa mokhoa oa hona joale oa ho lemoha phoso ea eddy sebakeng sa tlhahlobo ea hydrostatic. Ho fumanoa ha liphoso tsa Eddy hona joale ho etsoa ke GB7735 e tloaelehileng "Eddy Current Flaw Detection Method for Steel Pipes". Mokhoa oa hona joale oa ho lemoha phoso ke ho lokisa probe holim'a foreimi, ho boloka sebaka sa 3 ~ 5mm pakeng tsa ho lemoha phoso le weld, le ho itšetleha ka ho tsamaea ka potlako ha phala ea tšepe ho etsa tlhahlobo e feletseng ea weld. Letšoao la ho lemoha phoso le sebetsoa ka bo eona 'me le hlophisoa ka bo eona ka mochini oa eddy oa hona joale oa ho lemoha liphoso. Ho fihlela sepheo sa ho lemoha liphoso.

Mokhoa o otlolohileng oa ho sebetsa phala ea tšepe ea seam: Peipi ea tšepe ea seam e otlolohileng ke phala ea tšepe eo seam sa eona sa weld se bapileng le tataiso ea longitudinal ea phala ea tšepe. Matla a phala ea tšepe hangata a phahame ho feta a phala e otlolohileng ea seam welded. E ka sebelisa li-billet tse tšesaane ho hlahisa liphaephe tse cheselitsoeng ka bophara bo boholo, hape e ka sebelisa li-billet tse bophara bo lekanang ho hlahisa bophara ba liphaephe. Liphaephe tse fapaneng tse cheselitsoeng. Leha ho le joalo, ha ho bapisoa le liphaephe tsa seam tse otlolohileng tsa bolelele bo lekanang, bolelele ba weld bo eketseha ka 30 ~ 100%, 'me lebelo la tlhahiso le tlaase. Joale mekhoa ea eona ea ho sebetsa ke efe?

1. Forging steel: Mokhoa oa ts'ebetso oa khatello o sebelisang tšusumetso e khutlisetsang ea hamore ea forging kapa khatello ea mochine oa khatiso ho fetola sekheo hore e be sebopeho le boholo boo re bo hlokang.
2. Extrusion: Ke mokhoa oa ts'ebetso oa tšepe oo tšepe e kenngoa ka har'a cylinder e koetsoeng ea extrusion 'me khatello e sebelisoa ka lehlakoreng le leng ho ntša tšepe ho tloha ka sekoting sa lefu le behiloeng ho fumana sehlahisoa se felileng sa sebōpeho le boholo bo tšoanang. E sebelisoa haholo bakeng sa tlhahiso ea litšepe tse se nang ferrous. Tšepe ea lintho tse bonahalang.
3. Rolling: Mokhoa oa ho sebetsana le khatello eo tšepe e se nang letho e fetang ka har'a lekhalo (la libopeho tse sa tšoaneng) pakeng tsa para ea lirolara tse potolohang. Ka lebaka la ho hatelloa ha li-rollers, karolo ea thepa e fokotsehile 'me bolelele bo eketseha.
