At Piyush Steel, we take pride in being a trusted ASTM A106 Grade B carbon steel pipes manufacturer and supplier, known for their strength, durability, and high-temperature performance. Oil and gas, power plants, petrochemicals, refineries, and boilers extensively utilize these pipes due to their dependability in harsh circumstances. Whether for fluid transport, steam lines, or structural applications, our seamless pipes meet ASTM / ASME SA106 standards, ensuring reliable performance.
Table Of Content
A106 grade pipes are made with a precise blend of carbon, manganese, phosphorus, sulfur, and silicon, giving them exceptional mechanical strength, corrosion resistance, and heat tolerance. The minimum yield strength is 240 MPa, with tensile strength ranging from 415 MPa to 585 MPa, making them ideal for high-pressure and high-temperature applications. They are a flexible option for industrial applications that require long-term durability since they are comparable to materials like DIN St52, ASME SA106 Gr. B, & API 5L Grade B.
With thicknesses ranging from 50mm to 7.00mm and widths ranging from ½" NB to 36" NB, we provide A106 Grade B carbon steel pipes to meet various project needs. Depending on the application, you can choose from different schedules, such as SCH20, SCH40, SCH80, XS, and XXS, with end finishes including plain, beveled, and threaded options. A106 gr b pipes are available in seamless, ERW, and welded types, with various forms like round pipes, square pipes, rectangular pipes, black pipes, and zinc-coated pipes. Customization is available based on your specific needs.
Because of their high-pressure and high-temperature resistance, A106 Gr. B carbon steel pipes are extensively used in oil refineries, gas pipelines, structural engineering, shipbuilding, and power plants. The seamless construction makes these pipes perfect for steam pipelines, heat exchangers, and chemical processing plants. Additionally, as manufacturers of A106 Gr. B carbon steel round bars, we supply materials for structural and mechanical components, ensuring durability in heavy-duty applications.
As a trusted exporter of A106 Gr. B carbon steel pipes, we deliver high-quality products at competitive prices with fast, efficient worldwide shipping. Whether you need bulk quantities, specific sizes, or customized solutions, our team is dedicated to providing the best carbon steel pipes for your project.
