  Flange Connection Types: Pipe Flanges Selection Guides You Should Learn Flange Connection Types Pipe Flanges Selection Guides You Should Learn Image Source: Science Direct Pipe flanges Pipe Flanges are the projecting edges, rims, ribs, or collars that join two pipes or a pipe to a fitting or piece of equipment. For situations when solvent cementing would not hold, such as during the dismantling of a piping system or during a temporary or mobile installation, or when two materials have to transition into one another, pipe flanges are utilized. Flanges also have a high moment-carrying capability in comparison to other types of mechanical connections. This is a crucial quality for systems vulnerable to pipe-walking and lateral bending due to changes in temperature and pressure (e.g. deep water lines). Mechanical joints vs Flange pipe The most common application for mechanical joints is in an underground pipe, valve, and fitting connections. When in the retrained position, the mechan...

  How to Identification of BSPP,BSPT, NPT threads? When you choose valves and pipe fittings , thread is a very important feature you have to consider. No matter how well the product is made, a wrong thread type will make it useless. You have to determine the thread type before you order. British Standard Pipe fittings are among the most popular of all foreign threads in the world today. These threads come in two versions: parallel (BSPP), and tapered (BSPT). The thread flank angle for both tapered and parallel British threads is 55°. Although BSP is a foreign thread, it isn’t actually metric. This is why it comes in Imperial sizes: 1/8, 1/4, 1/2, 3/4, etc. BSP parallel (BSPP) threads commonly seal via a 30° chamfer on the male thread to a 30° cone seat inside the female thread (swivel only). If it is a port application, an O-ring and washer, Elastomeric seal or a bonded washer are needed to achieve a proper seal for parallel threads. For tapered BSP threads (BSPT), a seal is accomp...
