Steel flanges are essential components in many industrial systems, connecting pipes, valves and other machinery. They allow for secure fastening while also making maintenance, inspection and replacement easier. Here are three common uses of a steel flange.
Weld neck flanges for high-pressure systems
Weld neck flanges, like those seen at https://www.geldbach.co.uk/our-products/flanges/, are designed to manage high stress and are commonly used in pipelines that carry fluids or gases under significant pressure. Their long, tapered hub reduces stress concentration, which helps to maintain the integrity of the pipeline. They are particularly effective in environments where both temperature and pressure fluctuate, providing a reliable and long-lasting connection.
Socket weld flanges for small-bore lines
Socket weld flanges are most often used with small-diameter piping systems. The pipe is inserted into the socket and then welded around the joint, providing a smooth bore and strong connection. These flanges are particularly useful in applications involving moderate pressure where leakage must be minimised. Their compact design also makes them well suited to systems with limited installation space.
Blind flanges for sealing ends
Blind flanges are solid discs without a bore, designed to seal off the ends of pipes, valves or pressure vessel openings. They are frequently used when future expansion is planned, as they can be removed to extend the system. Blind flanges are also important in inspection and maintenance, as they allow sections of a pipeline to be isolated safely.
From steel flanges used in small systems to large industrial networks, selecting the right flange type ensures efficiency and safety across demanding applications.
