Liphaephe tse cheselitsoeng ka longitudinal
Selelekela sa Lihlahisoa
Liphaephe tsa tšepe tse cheselitsoeng ka longitudinal tseo ka tloaelo li aroloang ho latela thepa eo li entsoeng ka eona, tšebeliso ea tsona e reriloeng, le litekanyetso tseo li li khomarelang. Ka tloaelo, liphaephe tsa tšepe tse cheselitsoeng ka longitudinal tse buang ka maemo a tloaelehileng le likarolo tsa liphaephe tsa tšepe tsa Submerged-Arc Welded Steel.
Litekanyetso tsa thepa:
Longitudinal welded tšepe liphaephe ka classified ho itšetlehile ka lintho tse bonahalang tse ba entsoe ka, tse kang k'habone tšepe, tšepe e sa hloekang, alloy tšepe, joalo-joalo Mofuta o mong le o mong oa thepa e nang le litekanyetso tsa eona le litlhaloso.
Litekanyetso tsa tlhahiso:
Ts'ebetso ea tlhahiso ea Submerged-Arc Welded Steel Pipes e ka latela litekanyetso tse ikhethileng tse behiloeng ke mekhatlo e joalo ka American Petroleum Institute (API), American Society for Testing and Materials (ASTM), kapa mekhatlo e meng ea maemo a naha kapa ea machabeng ka tsela e latelang: API. 5L, API 5CT, ASTM 53, EN10217, DIN 2458, IS 3589, GB/T3091, GB/T9711,EN10217, EN10219
