Wings union (WECO type)

Wing unions & swivel joints have been used in the oilfield services for almost a century.
Originally branded under the Weco® names, the wing unions & swivel joints have built a worldwide reputation with generation to generation of field operators.
The Weco® names have developed into generic terms for the products themselves, after so many years usage, rather than an individual brand or manufacturer.
The applied technologies of wing unions & swivel joints have proven their high level of efficiency in extremely severe flow conditions such as very high pressure & flowrates, high & low temperatures, multiphase flow, erosive and corrosive agents, vibration in pumping piping  systems, etc.
Wing unions are also often referred to as hammer unions, hammer lug unions or Weco® dependent upon the customer or manufacturer.
Whatever name is used, they are the most common quick connection method for joining piping components together in a temporary system.

  1. Male & Female subs
  2. Quick connection
  3. Nuts
  4. Test plugs
  5. NPST assembly
Weco montage

They are the pressure containing parts of the assembly that provide metal-to-metal primary seal.
Subs are manufactured per different assembly modes:
    Butt weld assembly
    NPT threaded assembly
    NPST threaded assembly
    Sub profiles are also machined / forged as an integral part of a piping element.
Nut :
This is a forged part of assembly that allows connection of the two subs through a specific Acme or Iso thread.
Seal Element :
Seal element is an elastomer component which acts as a secondary seal to protect metal-to-metal seal against corrosion.
Depending on the union figure it can be a lip type ”Seal Ring” or an ”O-Ring”.

Different materials are available to suit fluid service (Buna for Standard service or FKM for H2S service).

Danger : Avoid the DANGER for interconnecting 2" Fig 602 and Fig 1002 with 2" Fig 1502.

Never strike, tighten, loosen or attempt repairs on pressurised components or connections.
Always apply essential care, handling and inspection to threaded components before, during and after make-up.
Never use severely worn, eroded or corroded components.
Never strike wing unions nuts having severely flattened and extruded ears.
Always use a bronze hammer in order to avoid sparkling while striking onto a wing union nut.

GROOVED NUTS :
Grooved nuts are generally used in industrial applications where assembly operation is more popularly done by the use of wrench rather than hammer.
Grooved nuts provide many advantages such as :
- Fast tightening.
- Zero vibration, shock and deforming while tightening.
- Limited overall dimension for installation and storage.
Ecrous rainures

 

 

 

 

 

 

DRILLED HOLES NUTS :
With suitable "Weco Rail" wrenches.
Ecrous oreilles percees

Male and female hammer union plugs are available in all figures and all sizes.
When ported, plugs can be used for different purposes (pressure testing, end of line drainage or venting).
Port is generally 1/2" NPT but can be threaded to client requirement.

NPST (Non Pressure Seal Thread)3604-NPST-EN :
The NPST assembly is a special design for Higher Pressure service which can replace welded or conventionally Threaded union construction.
In this instance it can be seen from the illustration that the threads are not exposed to well effluent which is the case with conventional threaded (ie L.P.) components
This type of construction, on straight flowline and pup joints, is generally more economically priced when compared to integral equipment.
