A hammer union, also called WECO couplings, is basically a connection common in the oil industries which consists of two joints integrated with threaded nuts. They allow for quick connecting the pipelines and flexible hose assemblies in the oil and gas industry. Sledgehammer hammer is used to hit the protrusions on the nut and strengthen the connections. Hammer unions are usually used for treating iron because of their malleability and ductility. SWBM hammer unions are made up to 15,000 PSI non-shock and cold working pressure and all have full working traceability. Mud tanks can be enjoined using the hammer Union without the need of rim connections.
While ordering hammer unions, following pointers should be kept in mind.
Mixing the different figure numbers of the hammer Union can be problematic
SWBM hammer Union subse nuts segments should only be associated with SWBM mating parts.
Exceeding the working pressure of the hammer Union can be hazardous.
Particular hammer union is designed for either standard or sour service. Therefore should not be used simultaneously.
The lugs of the hammer unions should be compensated as soon as they get worned out.
High pressure hammer unions are made from first alloy steel. It’s parts are fully replaceable with other new products. This proves to be beneficial because old parts will distort the part it is working on. Each and every product at SWBM is individually tested and a straightforward connection is built with the hammer Union in the manufacturing process as well. They generally have three parts; a male and a female and a nut.
A male part is an externally threaded portion, welded on the end of the pipe which is already connected to the tank wall for stop
A female part is the entrance for the pipe which continues to come through the nut towards the O-ring.
They are then hammered and tightened together.
Hammer unions are designated with numbers which do not tell the size of that particular product but its type. Also they are painted with specific colours to make the identification even more uncomplicated. They come in a variety of sizes depending on the type, ranging from 1″ to 12″. They are manufactured using heavy carbon steel or chromium molybdenum steel which makes them the premium quality that they are. Uses of hammer Union include the transfer of all kinds of media such as petroleum, gas, drilling mud, cement water, air etc on onshore and offshore drilling rigs. They are specifically designed to minimize fluid flow turbulence.
How to install Hammer Union?
In accordance with one aspect of the invention, a hammer Union assembly is provided. The Assembly includes an annual first member having a male end with an outer conical surface and a radially outwardly extending flange adjacent the male end. Further the Assembly includes an annular second member part having a female end with an inner tapered surface configured for sealed engagement with outer conical surface of the first member. The second member has an externally threaded portion adjacent the female end with an annular counterbore extending exilicity inwardly from the female end to provide a pocket facility. Furthermore assembly includes are not having internal female threads configured for threaded engagement with the externally threaded portion of the second member having radially inwardly extending flange configured to confront the daily outwardly extending flames of the first member. The assembly further includes an annular elastomeric seal disposed in the counterbore of the second member. The seal includes an annular rubber ring having a cylindrical inner surface and a cylindrical outer surface. The cylindrical outer surface extends between opposite corner edges with an annular steel ring recessed and bonded in one of the corner edges with an outer surface of the steel ring being exposed.
