Carbon steel products are favored for their exceptional toughness. They boast a robust impact strength, enabling them to endure conditions of high impact, wear, and tear. Available in various models, like the MSS SP-75 Stub Ends Type A and Type B, these products cater to diverse application needs. Notably, the Lap Joint Stub End features an additional lap joint, enhancing the security and robustness of the connection. Our Stub End Buttweld Fittings are crafted in both welded and seamless styles. While welded fittings are more commonly used, the seamless versions provide greater precision in sizing.
Explore the diverse range of standards and scales available for Stub Ends, such as the MSS SP-43 Type B Stub End. These are designed to meet various industry needs, including petroleum, petrochemical, oil and gas, power generation, sea water, marine environments, and pollution control systems. Each application demands specific properties, whether it’s strength, corrosion resistance, or toughness. For instance, the Stub End DIN 2642 caters to unique industrial requirements, while the Stub End EN 1092-1 type 35 is specifically engineered for high-pressure scenarios. We invite you to contact us to learn more about our widely used Stub End SS 304, other available grades, and to get a detailed price list.
