We are a reputable manufacturer, supplier, and exporter of Carbon Steel A105/A105N Flanges. These flanges are classified by the American Society for Testing and Materials as a standard for forged carbon steel pipe components, including carbon steel pipe flanges suitable for use in pressure systems at room temperature and above. Our product range includes Carbon Steel A105/A105N Blind Flanges, specifically designed to effectively contain and seal pipe ends in high-pressure applications such as hydraulic systems, as they exhibit exceptional bending stress resistance at the center.
Our Carbon Steel A105 Slip Flanges are suitable for non-critical conditions due to their low carbon content. For enhanced performance, we offer Carbon Steel A105N SWRF Flanges, which are standardized flanges. Additionally, we provide a wide variety of carbon steel ASTM A105 flanges, including ASTM A105 Slip Flanges, Carbon Steel Butt Weld Flanges, Carbon Steel Socket Weld Flanges, A105N Carbon Steel Blind Flanges, Carbon Steel Orifice Flanges, A105 Carbon Steel Spectacle Blind Flanges, A105 Threaded/Threaded Flanges, Carbon Steel Reducing Flanges, ASTM A105N Carbon Steel Ring Joint Flanges (RTJ), and more.
