Overview
Product overview
A Buttweld Long Stub End, also known as a Type B stub end, is a component used in piping systems to facilitate the connection of pipes of different sizes. Unlike short stub ends, which are welded directly to the piping system, long stub ends are designed to be bolted to flanges.
Fortune Fittings Private Limited offers a wide range of Buttweld Long Stub Ends manufactured to meet ASME B16.9 standards. These stub ends are available in various materials, including carbon steel and stainless steel, to suit different application requirements. Customers can choose from a variety of sizes and thicknesses to ensure compatibility with their piping systems.
Key features of Buttweld Long Stub Ends from Fortune Fittings Private Limited include precise dimensions and strict adherence to tolerances. Advanced manufacturing techniques are employed to guarantee ease of installation and reliability in use. This precision is crucial for maintaining a smooth and uninterrupted flow of fluid or gas in the piping system.
In addition to Long Stub Ends, Fortune Fittings Private Limited produces a comprehensive range of piping components, including elbows, tees, reducers, and flanges.
Customers can easily access sizing charts and product information to make informed decisions for their piping projects.
For Buttweld Long Stub End sizes, prices, dimensions, and other specifications, Fortune Fittings Private Limited offers a comprehensive range of products tailored to meet diverse customer needs.
Where it is used
Applications and service
Typical duty across the process industries we supply.
- Petrochemical IndustryLong stub ends are utilized in petrochemical plants for connecting pipes in various processes, including refining, distillation, and chemical synthesis. Their durability and resistance to corrosion make them ideal for handling harsh chemicals and high temperatures.
- Oil and Gas IndustryIn the oil and gas sector, long stub ends are employed in pipelines for transporting crude oil, natural gas, and refined products over long distances. They ensure secure connections between pipes, even in demanding environments such as offshore drilling rigs and refineries.
- Power GenerationPower plants rely on long stub ends to maintain the integrity of piping systems for conveying water, steam, and other fluids used in power generation processes. These fittings play a critical role in ensuring the efficient operation of boilers, turbines, and cooling systems.
- They are used in reactors, separators, and storage tanks to maintain fluid flow and prevent leaks, ensuring the safety and efficiency of chemical processes.
- Pharmaceutical and Food IndustriesLong stub ends are utilized in hygienic piping systems in pharmaceutical and food processing plants. They are made from materials that meet stringent regulatory standards for cleanliness and purity, making them suitable for applications where product integrity is essential.
- Water Treatment and DistributionMunicipalities and water treatment facilities utilize long stub ends in water distribution networks for supplying potable water to communities. These fittings help maintain the integrity of pipelines, ensuring the safe and efficient transport of water for drinking, irrigation, and industrial use.

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
