API 2B Q235B LSAW CARBON ROUND STEEL PIPE

Submerged arc welded steel pipes have high strength and toughness, can withstand large pressure and impact loads, and have good fatigue resistance, and can adapt to various complex stress environments. The weld quality of submerged arc welded steel pipes is high, the weld surface is flat and smooth, and there are no defects such as pores and slag inclusions, which effectively improves the sealing performance of the steel pipe and reduces the risk of leakage. In addition, submerged arc welded steel pipes also have good corrosion resistance and can maintain a long service life in harsh environments such as humidity, acid and alkali.
