Application Based Centrifugal Casting Solutions
Application 1: Ring Joint Gaskets (RJ Gaskets)
Application Overview
Ring Joint Gaskets are high-pressure sealing components used in oil & gas flanges, offshore drilling systems and refinery equipment. These components must withstand extreme pressure, temperature variations and corrosive environments.
Why Centrifugal Casting?
Centrifugal casting ensures superior concentricity, high-density outer structure, reduced internal porosity and uniform alloy distribution — critical for leak-proof performance.
Casting Requirements
| Parameter | Requirement |
| Typical OD Range | 100 mm – 1200 mm |
| Wall Thickness Control | ±2% consistency |
| Material Grades | Inconel, Monel, Stainless Steel, Alloy Steel |
| Concentric Accuracy | High precision horizontal & vertical casting |
| Surface Finish | Machining allowance optimized |
Recommended Machine Solution

Application 2: Hub Pipes
Application Overview
Hub pipes are structural transmission components used in pipelines, offshore installations and refinery systems. These components require heavy wall thickness and high pressure resistance.
Why Horizontal Centrifugal Casting?
Horizontal centrifugal casting provides uniform wall thickness along the pipe length, high structural integrity and reduced shrinkage cavities.
Casting Requirements
| Parameter | Requirement |
| Diameter Range | 100 mm – 1500 mm |
| Length | Up to 6 meters |
| Material | High alloy Cr-Ni steel |
| Wall Thickness | Heavy wall casting capability |
| Straightness | Controlled post-solidification |
Recommended Machine Solution

Application 3: Alloy Tubes (Reformer Tubes)
Application Overview
Alloy tubes used in refineries operate under continuous high temperature and corrosive environments. These include reformer furnace tubes and process tubes.
Why Centrifugal Casting?
Centrifugal casting ensures directional solidification, high outer wall density, reduced internal defects and improved creep resistance for long service life.
Casting Requirements
| Parameter | Requirement |
| Tube Length | 3 – 6 meters |
| Diameter | 100 mm – 1000 mm |
| Alloy Grades | HK40, HU, 25Cr35Ni, 35Cr45Ni |
| Wall Thickness | Precision controlled |
| Heat Resistance | 900 – 1100°C operating range |
