What is a Buttweld Short Stub End?
A Buttweld Short Stub End is a type of piping component used in industrial applications to terminate or cap off a pipeline. It is designed to be welded directly onto the piping system and is commonly used in low-pressure applications. The short stub end is shorter in length compared to its counterpart, the long stub end, and is typically used when space constraints are a concern or when a shorter length is sufficient for the application. It provides a secure and leak-proof seal when welded to the pipe, ensuring the integrity of the piping system.
Where it is used
Applications and service
Typical duty across the process industries we supply.
- Low-Pressure Piping SystemsShort stub ends are often used in low-pressure piping systems where welding directly to the pipe is feasible and cost-effective.
- Plumbing and HVAC SystemsThese stub ends are suitable for plumbing and HVAC systems, providing a reliable connection between pipes of different sizes.
- Process IndustriesIn process industries such as chemical plants, refineries, and pharmaceutical facilities, short stub ends are utilized for connecting pipes in process lines and utility systems.
- Water Treatment PlantsShort stub ends are employed in water treatment plants for connecting pipes carrying water, chemicals, and other fluids, ensuring efficient flow and reliable operation.
- Food and Beverage IndustryIn the food and beverage industry, where hygiene and sanitation are critical, short stub ends are used to connect pipes in production lines and utility systems.
- Petrochemical IndustryShort stub ends play a vital role in the petrochemical industry, facilitating the transfer of various fluids and gases in refining and processing operations.

Technical notes
How the component behaves in the line, and the details to settle before an order is placed.
How it behaves in the line
- Stub end is welded to pipe: material must match pipe grade
- Lap joint (backing) flange is loose: can be carbon steel even if stub is SS
- Not suitable for high-temperature creep or fatigue service: lap joint can lift off
- Type A (long pattern) and Type B (short pattern) per ASME B16.9
Confirm when ordering
- Specify Type A or Type B (length)
- Specify if matching loose lap joint flange is required
- Match stub material to pipe; flange material can differ
