HAK-PI Flat Flange PN40 DN350
Zero-leak sealing and long service life on high-pressure, large-diameter lines.
HAK-PI Flat Flange PN40 provides reliable connections on large-diameter pipelines. In addition, its carbon steel body and EN 1092-1 compliance give it international validity, therefore it suits high-pressure duty. Furthermore, the bolted system simplifies assembly and maintenance.
The flange operates stably between -10°C and +120°C and withstands pressures up to 40 bar. Its standard bolt hole pattern, moreover, mates with gaskets for a tight joint, and the protective paint coating raises corrosion resistance in harsh environments. As a result, sealing and durability hold up over long service.
