Understanding your choice of forged stub ends options
As a leading provider of forged stub ends, we understand the importance of selecting the right option for your needs. With so many choices available, it can be overwhelming to determine which option is the best fit for your project. At Jihua, we will break down the various types of forged stub ends and their unique features, helping you make an informed decision.
What is a forged stub end?
Forged stub end is a steel butt weld pipe fittings inside, generally a section inside the lap joint flange.
A lap joint flange is Commonly used when the medium temperature and pressure are not high and the medium is more corrosive. When the medium is more corrosive, the flange part is in contact with the medium that stub end for corrosion-resistant high-grade materials such as stainless steel, while the external use of low-grade materials such as carbon steel.
Types of Forged Stub Ends
Stub ends are manufactured in three primary types: Type A, B, and C. Each type has unique features and applications, as outlined below:
- Type A Stub Ends: Type A stub ends are designed and machined to fit lap joint flanges. The mating surfaces of the stub end and the lap joint flange have a matching profile and surface, ensuring a perfect fit. The lap thickness of Type A stub ends is greater than or equal to the minimum wall thickness of the connected pipe. The outside corner of Type A has a radius to accommodate the lap joint flange, while the inside corner is squared.
- Type B Stub Ends: Type B stub ends are designed for standard slip-on flanges that act as lap-joint flanges. Similar to Type A, the lap thickness of Type B stub ends is greater than or equal to the minimum wall thickness of the connecting pipe. The lap of Type B stub ends usually has a serrated face. Chamfers on the ID side of the flange are required to ensure tight joints.
- Type C Stub Ends: Type C stub ends can be used with lap joint and slip-on backing flanges. These stub ends are fabricated from pipes, and the lap is flared over. The lap thickness of Type C stub ends is 75% of the connecting pipe’s wall thickness. Type C has a short fillet outer radius capable of hosting any backup flange.
- Type CS Stub Ends: Type CS stub ends are similar to Type C, but with a key difference: the lap face has concentric serrations machined during the manufacturing process.
Common Types and Lengths
Stub ends are typically manufactured in two ways: Type A and Type B. They are available in two standard lengths: long (ANSI) or short pattern (MSS).
Short and Long Pattern Stub Ends (ASA/MSS)
Schedule 5s and 10s stub ends are usually offered in short lengths, with long lengths available on special order. Schedule 40s stub ends are supplied in either short or long lengths.
Stub ends come in two different patterns:
- The short pattern, known as MSS-A stub ends.
- The long pattern, known as ASA-A stub ends (or ANSI length stub ends).

The Forging Process of Forged Stub Ends
The forging process of forged stub ends with blanking to packaging and delivery. Understanding these processes will give you insights into the precision, dedication, and expertise required to create high-quality forged stub ends.
1. Blanking
The forging process of forged stub ends with blanking. In this initial stage, the raw material, typically steel or another metal alloy, is cut into appropriately sized pieces, called blanks, which will be used for forging. The blanking process ensures that the material is uniform in size and shape, providing a consistent starting point for the subsequent forging stages.
2. Heating
Once the blanks have been prepared, they are heated to achieve the ideal forging temperature. The heating process typically involves placing the blanks inside a furnace or induction heater, where they are heated to a specific temperature range that allows optimal malleability and ductility. This step is crucial, preparing the metal for intense pressures and deformation during the forging process.
3. Forging of Forged Stub Ends
The heated blanks are then transferred to a forging press or hammer, where they are subjected to immense pressure, causing the metal to flow and take on the desired shape of the forged stub ends. This process may involve open-die forging, where the metal is shaped between two flat dies, or closed-die forging, where the metal is forced into a pre-shaped die cavity to form the desired component. Forging imparts greater strength and durability to the stub ends, aligning the metal’s grain structure and eliminating any internal voids or defects.
4. Rough Turning of Forged Stub Ends
After the forging process, the forged stub ends are subjected to a rough turning process. This involves using a lathe or other machining tool to remove excess material and achieve a more precise shape. The rough turning process helps to reduce surface irregularities and ensure that the forged stub ends meet the required dimensional tolerances.
5. Solid Solution Treatment of Forged Stub Ends
Following rough turning, the forged stub ends undergo a solid solution treatment. This process involves heating the stub ends to a specific temperature, making the metal’s microstructure homogenous. The stub ends are then rapidly cooled or quenched to lock in the desired microstructure. This treatment increases the forged stub ends’ corrosion resistance and mechanical properties.
6. Fine Machining Before Strengthening
The next step involves fine machining, where the forged stub ends are refined to achieve the desired dimensions and surface finish. This process may include additional turning, milling, or grinding operations to ensure that the stub ends meet the necessary specifications.
7. Cold Deformation Hydraulic Bulging Strengthening
They are subjected to cold deformation hydraulic bulging strengthening to enhance further the strength and durability of the forged stub ends. This process involves applying controlled pressure to the stub ends, causing them to expand and form a more robust structure. The hydraulic bulging process imparts additional strength to the forged stub ends without compromising their dimensional accuracy or surface finish.
8. Heat Treatment to Eliminate Residual Stress
Following the cold deformation process, the forged stub ends undergo a heat treatment to eliminate residual stresses. This heat treatment involves heating the stub ends to a specific temperature, holding them at that temperature for a defined period, and then cooling them down gradually. The process helps to relieve any internal stresses that may have developed during the forging and deformation processes, ensuring that the forged stub ends maintain their desired shape and mechanical properties.
9. Physical and Chemical Testing
To ensure the quality and performance of the forged stub ends, they are subjected to a series of physical and chemical tests. These tests may include tensile strength testing, hardness testing, and chemical composition analysis. These tests help to verify that the forged stub ends meet the required material specifications and performance standards, ensuring their suitability for use in various industries and applications.
10. Non-Destructive Testing after Finishing
After the physical and chemical testing, the forged stub ends undergo non-destructive testing (NDT) to evaluate their integrity and quality further. NDT methods, such as ultrasonic testing, radiographic testing, and magnetic particle inspection, are employed to detect any internal or surface defects that may compromise the performance of the forged stub ends. These tests are crucial in maintaining the highest level of quality and ensuring that the finished products are defects-free.
11. Packaging and Delivery
Once the forged stub ends have passed all the necessary quality control tests, they are prepared for packaging and delivery. The stub ends are carefully packaged to prevent damage during transportation and ensure that they arrive at their destination in perfect condition. Packaging may include the use of protective padding, crates, or pallets, depending on the size and quantity of the stub ends being shipped. Finally, the packaged forged stub ends are shipped to the customer or end-user, ready for use in their respective applications.
