API 5L:
ASTM A53:ASTM A53 ni vipimo vya kawaida vya bomba, chuma, nyeusi na iliyochovywa moto, iliyofunikwa na zinki, iliyochomwa, na isiyo imefumwa. Compliance with ASTM A53 ensures that the LSAW steel pipe meets specific requirements for use in mechanical and pressure applications, as well as for general use.
ASTM A252:vipimo vya kawaida kwa piles za mabomba ya svetsade na imefumwa. Linapokuja suala la mabomba ya chuma ya LSAW (Longitudinal Submerged Arc Welded), kufuata ASTM A252 ni muhimu hasa kwa maombi yanayohusisha milundo ya mabomba ya chuma yanayotumiwa katika ujenzi na miradi ya usaidizi wa miundo. ASTM A252 inabainisha mahitaji ya kiufundi kwa rundo la mabomba ya chuma, ikiwa ni pamoja na vipimo, sifa za kiufundi na taratibu za kupima.
LSAW steel pipes that comply with ASTM A252 are designed to meet the specific requirements for use in piling applications, such as foundation construction, marine structures, bridge construction, and other civil engineering projects. Utiifu wa ASTM A252 huhakikisha kuwa mabomba ya chuma ya LSAW yanakidhi ubora, utendakazi na viwango vinavyohitajika vya usalama kwa matumizi yanayokusudiwa katika uwekaji rundo.
