Threaded Equal Cross Tolerances as per ASME B16.11
| Parameter | Tolerance | Notes |
|---|---|---|
| Outside Diameter (OD) | ±1% of nominal OD | Applies to all material grades (CS, SS, Alloy Steel, High Nickel Alloys) |
| Wall Thickness (SW) | +0.38 mm / -0.0 mm | Ensures proper strength for socket weld connections |
| Wall Thickness (THD) | As per thread fit | Matches ASME B1.20.1 internal/external thread tolerances |
| Face-to-Face / Overall Length | ±1.5% of nominal length | Applies to both equal and unequal crosses |
| Socket Depth (SW) | +0.25 mm / -0.13 mm | Ensures proper pipe insertion and leak-proof joint |
| Thread Fit (THD) | Per ASME B1.20.1, Class 2A/2B | Standard pitch and diameter tolerance |
| Branch Angle | 90° ±1° | Applies to both equal and unequal types to maintain alignment |
| Unequal Branch Difference | ±1 mm | Dimensional tolerance between different branch sizes |
What distinguishes equal and unequal forged crosses?
- Equal Forged Cross: All four branches have the same nominal diameter, ensuring uniform flow and symmetrical piping layouts. Ideal for systems where pressure drop needs to be consistent across all branches.
- Unequal Forged Cross: Branch diameters differ, allowing connection of pipes of varying sizes. This design accommodates complex piping networks where flow distribution or pressure requirements vary. Unequal crosses are often used in process lines, where main pipelines feed multiple branch lines of different sizes.
What are the key differences between socket weld and threaded forged crosses?
- Socket Weld (SW): The pipe is inserted into the socket end and fillet-welded externally. Provides a high-strength, leak-proof joint suitable for high-pressure and high-temperature systems. SW crosses require precise machining of socket depth and bore to ensure full insertion of the pipe.
- Threaded (THD): Involves internal/external threads for pipe assembly without welding. Easier to install and dismantle but generally limited to moderate pressure applications. Thread tolerances must adhere to ASME B1.20.1 standards for a secure fit.
How do forged crosses differ from cast or welded crosses?
- Forged Crosses: Superior mechanical strength, better grain structure, suitable for high-pressure and critical applications.
- Cast Crosses: More economical but weaker, prone to porosity and not recommended for high-pressure systems.
- Welded Crosses: Made by joining pipes or plates, useful for very large sizes but require more fabrication time and inspection.
