Common Rail
View system integration details
This page explains how Rail Pipe is classified within Motor Vehicle Manufacturing. Technical values and manufacturer relationships are research references; confirm the current specification and supplier evidence for each order.
A high-pressure pipe that distributes fuel from the common rail to individual injectors in a diesel engine's fuel injection system.
Technical details and manufacturing context for Rail Pipe
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Burst Pressure | ≥2.5 MPa | Safety factor of 1.5 over max operating pressure |
| Inner Diameter | 6–12 mm | Determines flow capacity |
| Outer Diameter | 12–20 mm | Affects wall thickness and strength |
| Length | 200–600 mm | Customizable per engine layout |
| Wall Thickness | 3–5 mm | Minimum 3 mm for pressure rating |
| Surface Roughness | Ra 0.8–1.6 μm | Critical for sealing surfaces |
| Material Grade | 25CrMo4 | High-strength alloy steelDIN 17204 |
| Operating Temperature | -40–85 °C | Non-condensing environment |
| Weight | 0.5–2.0 kg | Depends on length and wall thickness |
Ranges are indicative industry figures for RFQ preparation, not a supplier commitment. Confirm every value and standard with the legal manufacturer before ordering.
| pressure: | Up to 2500 bar (36,250 psi) |
| flow rate: | Dependent on engine displacement and injector flow requirements |
| temperature: | -40°C to +150°C |
| slurry concentration: | Not applicable - designed for clean diesel fuel only |

1 company lists this product among what they make. Company figures are quoted from each company's own website; every card states where the relationship came from.
Explore company information and manufacturing capabilities, then discuss the scope of your project with a relevant supplier.
Ask for use case, specification boundaries, supplier type, and RFQ preparation information for this product.
The directory lists high-strength steel alloy as the material, with a specific grade of 25CrMo4 per DIN 17204. This grade is commonly used for high-pressure applications due to its strength and toughness. Confirm the exact material specification with the supplier for your engine model.
The directory lists a burst pressure of at least 2.5 MPa, with a safety factor of 1.5 over maximum operating pressure. To verify, you should refer to the manufacturer's datasheet or conduct a hydrostatic test per relevant standards. Always confirm the burst pressure rating for the specific pipe you intend to use.
Reference ranges are: inner diameter 6–12 mm, outer diameter 12–20 mm, wall thickness 3–5 mm, and length 200–600 mm. These are general ranges; the exact dimensions depend on the engine layout and flow requirements. Consult the manufacturer for precise specifications.
