Technical Features and Specifications
Forged cylinders provide superior pressure containment and axial rigidity.
| Feature | Detail |
|---|---|
| Manufacturing | Mandrel forging (expanding a punched hole). |
| Materials | A105, F316L, 4130, 4140, Inconel. |
| Pressure Rating | Designed for ultra-high pressure (10,000+ PSI). |
Because they are forged, these cylinders have no "longitudinal weld seam," which is usually the weakest point in a pressure vessel. This allows engineers to reduce wall thickness—and thus weight—without sacrificing safety. The internal and external surfaces are rough-machined to remove any forging scale, ensuring a clean substrate for final finishing or honing.

Buying Tips for Pressure Systems
- Wall Uniformity: Request ultrasonic thickness gauging to ensure the wall is consistent throughout the length of the cylinder.
- ID Finish: If being used for a hydraulic piston, specify the "Honing" allowance required to reach a mirror finish (usually 0.4 Ra or better).
- End Preparations: Specify if you need the ends "beveled" for welding or "thickened" for threaded caps.
Advantages of Forged Hollows
| Advantage | Operational Benefit |
|---|---|
| Maximum Hoop Strength | Safest choice for high-pressure gas or fluid storage. |
| Zero Seam Risk | Eliminates the need for 100% X-ray inspection of longitudinal welds. |
| High Speed Balance | Uniform density allows for easier balancing of high-speed rollers. |
Primary Applications
| Application | Usage Context |
|---|---|
| Hydraulic Jacks | Main cylinders for 1000+ ton industrial presses. |
| Nuclear Power | Reactor coolant pump housings and small vessel shells. |
| Paper Industry | High-speed "Suction Roll" shells for paper machines. |
- Q: What is the maximum length of a forged cylinder?
- A: This depends on the diameter and the forging press capacity. We can produce cylinders several meters long by utilizing specialized "drawing" techniques on the mandrel.
