A seamless pipe is manufactured by drawing a solid steel billet through a piercing rod. Welded pipes are produced by cutting, bending, welding coils (ERW) or steel plates (LSAW). SEAMLESS PIPE Seamless pipes are produced starting from steel billets, that are... read more »

Flanges for Pipes and Piping Systems https://blog.projectmaterials.com/flanges/flange-meaning/?utm_source=rss&utm_medium=rss&utm_campaign=flanges-pipe-flange https://blog.projectmaterials.com/flanges/flange-meaning/#respond Tue, 18 Dec 2018 19:17:22 +0000 http://blog.projectmaterials.com/?page_id=1335 In piping applications, a flange is used to join a pipe with other equipment (another pipe, a valve or a pump). Pipe flanges may be classified by shape (weld neck, blind, socket weld, threaded, etc), by facing type (RF, FF, RTJ), by material grade (cast and forged), and by specification (the ANSI/ASME B16.5 and B16.47 specifications... read more »

Olet fittings are a family of forged products used to make 45 or 90 degrees integrally reinforced branch connections (deviations) from a run pipe (also called, header pipe) to a branch pipe (outlet pipe). The common types of branch fittings are Weldolet, Thredolet, Sockolet, Latrolet,... read more »
