Range Of Sizes And Branch Sizes
Welding outlets come in a range of sizes to suit different pipeline requirements. The branch sizes of these fittings typically vary from ½ inch (16 mm) to 16 inches (419 mm), allowing for flexibility in connecting auxiliary pipes of various diameters to the main pipeline. It’s important to note that upon request, welding outlets can be customized to meet specific project needs.
Apart from branch sizes, welding outlets are also designed to be compatible with different header sizes. The header refers to the main pipeline or the pipe to which the welding outlet is connected. The header pipe sizes can range from ½ inch (16 mm) to 38 inches (965 mm), ensuring compatibility with a wide range of pipeline systems.
Construction And Manufacturing Process
The construction and manufacturing process of welding outlets is crucial to ensure their integrity and reliability. These fittings are manufactured in accordance with EEMUA-234 standards, which dictate the use of hot forging and machining techniques.
The process starts with the extrusion of bars, which are then subjected to hot forging to shape them into the desired form. After the hot forging process, the fittings undergo machining to achieve precise dimensions and tolerances.
It is important to note that welding outlets are specifically designed for welding to seamless and seam-welded pipes. This ensures a strong and secure connection between the welding outlet and the main pipeline, minimizing the risk of leaks or failures in critical applications.

Self-Reinforced Connection Design
One of the notable design features of welding outlets is their self-reinforced connection design. This design eliminates the need for additional reinforcement or support, minimizing the complexity and cost of installation. The self-reinforced connection relies on the structural integrity of the welding outlet itself, ensuring a reliable and robust connection to the main pipeline.
To comply with industry regulations, welding outlets are manufactured in accordance with B31.3 Section 304.3. This ensures that the fittings meet the necessary standards for structural integrity and safety in welding applications.

- Structural integrity of welding outlet ensures reliable connection to main pipeline
- Compliance with B31.3 Section 304.3 ensures standards for safety and integrity
Smooth Entry And Reduced Turbulence
Welding outlets are designed to provide a smooth entry point for the flow of fluids through the branch connection. This smooth entry minimizes the occurrence of turbulence, ensuring optimal operation and minimizing pressure losses in the pipeline system.
The dimensions and tolerances of welding outlets are manufactured to meet the requirements specified in EEMUA-234. These precise measurements ensure a proper fit and alignment when welding the outlet to the header and branch pipes. Additionally, the gap distance, header pipe radius, and fitting inlet radius are all carefully considered to facilitate a smooth entry and reduce turbulence within the system.
In conclusion, welding outlets are essential fittings in the field of welding, serving as branch connections for seamless and seam-welded pipes. Constructed through hot forging and machining from extruded bars, these fittings ensure strength and reliability. With a wide range of sizes and branch sizes available, welding outlets offer flexibility for various pipeline configurations. The self-reinforced connection design, in compliance with industry standards, provides a secure and cost-effective solution. Furthermore, the smooth entry and reduced turbulence features contribute to efficient fluid flow and optimal performance of the pipeline system.

Frequently Asked Questions
What is welder outlet?
A welder outlet is a specific type of electrical outlet designed to provide power for welders. It typically has a 3-prong configuration and is capable of delivering high amperage, usually 50 Amps. The most commonly used welder outlets are the NEMA 6-50P and NEMA 10-50P plugs. While the NEMA 6-50P is the more prevalent grounded plug design, the NEMA 10-50P is an older non-grounded style that is less common. Regardless of the type, there are various adapters available to connect these plugs to different power sources, ensuring compatibility and efficient power supply for welding purposes.
What size are welding outlets?
The welding outlets come in a range of sizes, catering to various needs. They can fit branch sizes starting from ½ in./16 mm to 16 in./419 mm, with additional sizes available upon request. These versatile welding outlets are designed to be applied to header sizes ranging from ½ in./16 mm to 38 in./965 mm, ensuring compatibility with a wide range of applications.
What voltage are welding outlets?
Welding outlets are typically rated at 440V, 3Ph, 63A. This indicates that the outlet can handle a current of up to 63 amps per phase. However, it’s important to note that the actual welding process often involves the use of a step-down transformer, allowing for much higher welding amps (single phase). So, while the receptacle can handle a maximum of 63A, the welding amps can be significantly higher.
How many amps does a welder outlet use?
The number of amps a welder outlet uses depends on the voltage required by the welder. For a welder running on a 115V primary, the minimum breaker size is 20A, while a recommended breaker size is 30A. This would be suitable for welding at up to 140 amps. On the other hand, a welder running on a 208-230V primary requires a minimum breaker size of 30A, with the recommended size being 50A. This setup is suitable for welding at up to 180 amps.
