Bolts for the oil industry are manufactured in accordance with ASTM, European and SRPS standards, in order to meet the highest requirements of resistance to pressure, high temperatures and corrosive environments. At the customer’s request, the bolts are also made of stainless steel. We place special focus on the use of Duplex and Super Duplex steels, which provide exceptional mechanical strength and superior corrosion resistance, especially in contact with seawater and chemically aggressive substances.
