The Advent of Welded Outlets in Engineering

Apr 6, 2024 | News

Welded outlets are specializing in forged fittings designed to create reinforced branch connections from a main pipeline (header pipe) to a secondary pipe (outlet pipe). These fittings play a crucial role in piping systems, allowing directional changes and integration of additional lines.

Production Methods of welded outlet

  • Forging:

Welded outlets are typically forged components. Forging ensures high strength and durability.

The manufacturing process involves shaping the material under high pressure using dies to create the desired outlet shape.

  • Welding:

Weldolets are installed through welding, which is how they get their name.

The fitting has a welding outlet on one end, which is welded onto the main pipe.

The other end accommodates the smaller branch pipe or component with a threaded or socket weld connection.

Materials of welded outlet

  • Weldolets can be made of various compatible pipe materials, including:
  • A105 carbon steel
  • Stainless steel
  • Alloy steel
  • Nickel alloys

Types of welded outlet

  • Weldolet: A weldolet provides a welded outlet connection. It allows you to branch off from the main pipe using a 45 or 90-degree angle. Grooved Welded Outlet is a specialized ductile iron fitting designed to allow a grooved pipe to be welded into a manifold, header, or vessel. These fittings feature a grooved end and a machined flange or threaded end that is specifically suited for welding.
  • Sockolet: Sockolets are socket-welded outlet fittings. They connect the header pipe to the outlet pipe using socket welding. Sockolets are versatile and find applications in both high- and low-temperature systems.
  • Thredolet: Thredolets are threaded welded outlet fittings. They create branch connections by threading the outlet pipe. Thredolets are suitable for applications where socket welding is not feasible.
  • Latrolet: Latrolets provide lateral branch connections. They allow branching at a 45-degree angle from the header pipe. These fittings are commonly using in piping systems that require a change in direction.
  • Elbolet: Elbolets are elbow-shaped branch fittings. They create 90-degree branch connections. Elbolets are useful when you need to turn the outlet pipe at a right angle.

Applications of welded outlet

  • Branch Connections:

Weldolets are using to create branch connections from a larger main pipe to a smaller pipe or pipeline component. They replace traditional piping tee connections. When standard piping tee fittings are not available for specific branch sizes, weldolets come in handy.

  • Space Efficiency:

Weldolets are smaller in size than traditional tee fittings, making them ideal when space is limited in the system. They take up less space while providing efficient fluid or gas flow.

  • Integral Reinforcement:

Weldolets provide integral reinforcement or self-reinforcement at the branch connection. This ensures structural integrity and minimizes turbulence.

  • Standardization:

The Manufacturers Standardization Society (MSS) publishes the SP-97 standard, specifically addressing integrally reinforced forged branch outlet fittings, including weldolets. This standard provides guidelines for design, manufacturing, dimensions, testing, and marking.
