API 5L darajasidagi X42 ERW liniyasi quvuri

API 5L X42 welded pipe: API stands for the American Petroleum Institute, with "X" denoting the first letter of "pipeline" in English, capitalized; "42" indicates a minimum yield strength of >420 MPa. X42 quvur liniyasi trubkasi X42 po'latdan yasalgan quvur liniyasi bo'lib, tekis uchlari, tishli uchlari va rozetka uchlari mavjud. U payvandlash, ulash, rozetkaga ulanish va boshqalar orqali ulanadi API 5L X42 payvandlangan quvur odatda neft va tabiiy gaz uzatish quvurlarini qurishda qo'llaniladi.
