We are manufacturers, suppliers and exporters of Carbon Steel A105 / A105N Flanges which, the American Society for testing materials, classified as a standard that covers forged Carbon-Steel piping parts that also include flanges, which are serviceable in pressure systems at room temperatures as well as temperatures higher than it. We produce Carbon Steel A105 / A105N Blind Flanges which are successful in pressure bearing and sealing pipe ends in heavy pressure applications like hydraulic systems since they have maximum bending stress at the center.
Our Carbon Steel A105 Slip On Flanges are meant for non-critical conditions, as they have a low Carbon content. However, our Carbon Steel A105N SWRF Flanges are ‘normalised’ flanges for better work performance.
