Flowline Fittings of Hammer Union FIG 1502 Integral Elbow and Double Thread Wing

FIG 1502 refers to a hammer union, a type of high-pressure flowline fitting commonly used in the oil and gas industry. The 1502 indicates working pressure of 15,000 psi, making it suitable for extremely high-pressure environments like well testing, fracturing, and cementing. 2” denotes a 2-inch nominal size.

Integral Elbow, Double Thread and Double Wing differ in function and union connection 2” FIG1502 WxT.

2″ FIG 1502 Elbow

PME 2″ FIG 1502 elbow is a fitting designed to change the direction of a high-pressure flowline. It’s a type of integral fitting, which means the hammer union connections are forged directly into the body of the fitting. The elbow is available in a 90-degree angle, but 45 degree exist. PME integral 90 Deg Elbow primary use is in a manifold or flowline system to create a turn without requiring additional components. The ends of the elbow can be a combination of male (wing) and female (thread) connections, depending on the specific application.

2″ FIG 1502 Double Thread

PME 2″ FIG 1502 double thread fitting, also known as a threaded hammer union, is used to connect two pieces of pipe or equipment that have a wing end connection. This type of fitting allows for quick assembly and disassembly, which is crucial for temporary flowline setups and maintenance. Double Thread implies that both connections are female threaded, allowing it to join two male pieces.

2″ FIG 1502 Double Wing

PME 2″ FIG 1502 double wing fitting, often a crossover union or a pup joint, is a connector with male wing connections on both ends. This allows it to connect to two female-threaded hammer union ends. The wing refers to the lug-like projections on the nut of the hammer union, which allows it to be quickly tightened or loosened with a hammer. This type of fitting is essential for making transitions between different components in a high-pressure system.
