Connections of pipe fittings

Connections of pipe fittings
Pipeline fittings are an important part of the pipeline system and are used to connect different pipes, fittings and equipment. According to different connection methods, pipeline fittings can be divided into welding joints, threaded joints, flange joints, clamp joints and other types.
1 . Welded joint is a joint that connects two pipes or fittings together by fusion. Common welded joints include butt welding, fillet welding, ring welding, etc. Butt welding is to align the ends of two pipes and then weld them, and is suitable for connecting pipes of the same diameter. Angle welding is to connect the ends of two pipes or pipe fittings together at an angle of 90 degrees, and is suitable for connections at bends. Ring welding is to join the ends of two pipes or fittings together in the shape of a ring, and is suitable for branching of pipes.
2 . Threaded Joint A threaded joint is a joint that connects two pipes or fittings together by means of a threaded connection. Common threaded joints include female and male threaded joints. A female threaded fitting is a connection between a pipe with a female thread and a pipe with a male thread, and is used for small diameter pipes. Male threaded couplings are used to connect a male threaded fitting to a female threaded fitting and are used for large diameter piping. 3 . A flange joint is a joint that connects two pipes or fittings together by means of a flange connection. A flange is a flat ring-shaped part with a hole that is bolted together to form a sealed connection. Common flange joints include flat welding flanges, butt welding flanges, threaded flanges, etc. Flat welding flanges are two flat flanges connected together and are suitable for low pressure and small diameter pipe connections. Butt-welding flanges are two flanges with flanges connected together, suitable for high pressure, large diameter pipeline connection. Threaded flange is a flange with a thread and a pipe with internal thread connected together, suitable for small diameter pipeline connection. 4 . A clamp joint is a joint that connects two pipes or fittings together by means of a clamp. A clamp is a flexible ring-shaped part that is bolted together to form a sealed connection. Common clamp joints include single clamp joints, double clamp joints, etc. A single clamp joint is one clamp over a pipe, and the clamp is connected to another pipe by bolts, which is suitable for the connection of small diameter pipes. Double-clamp coupling is to put two clamps on the pipe and connect the two clamps together by bolts, which is suitable for the connection of large-diameter pipes. In short, different pipeline systems need to choose different pipeline matching joint connection methods to ensure the safe, reliable and efficient operation of the pipeline system.
