A Closer Look at Industrial Grade Flange Spreaders
In heavy industry, massive pipe flanges form secure connections to transport high-temperature fluids or corrosive chemicals. Safely separating these stubborn high-pressure flanges for inspection and maintenance requires robust flange spreading equipment, and specialized flange spreaders provide the utmost mechanical advantage, alignment control, and damage resistance when dismantling large commercial and industrial flanged joints.
Challenges of Industrial Flange Separation
Industrial flanges vary in size from NPS ½” to NPS 60”+. Attempting to separate the flanges using makeshift methods risks injury to the technicians and surrounding staff, broken bolts, or flange warping. Plus, without industrial flange alignment tools, improper alignment during spreading can permanently damage flange sealing surfaces. This leads to leaks or even dangerous bursts down the road.
The Role of Robust Flange Spreading Equipment
High-strength flange tools are designed to safely and efficiently separate flanged joints. They’re vital for various industrial applications, including:
- Oil and gas refineries
- Chemical processing plants
- Power generation facilities
- Ship and marine construction
- Wind and solar energy
Types of Industrial Grade Flange Spreaders
Industrial flange spreaders come in two main configurations, each suited for different applications:
Manual Flange Spreaders
Manual flange spreaders are a cost-effective option for separating flanged joints with low to moderate pressure ratings. They’re ideal for:
- Routine maintenance procedures
- Applications with limited access to an external power source
- Flanges in confined spaces (due to their typically compact design)
Manual (or mechanical) spreaders utilize a screw mechanism to generate spreading force. They’re generally operated by turning a hand screw or using a torque wrench. Key features of manual flange spreaders include:
- Simple operation – Easy to use and requires minimal training.
- Lightweight and portable – Well-suited for field applications, especially when you have a carry case and the entire kit weighs 12kg.
- Moderate spreading force – Can produce a max spreading force of 9.4 tons.
Hydraulic Flange Spreaders
For the toughest jobs, hydraulic flange spreaders are the answer. They use a hydraulic cylinder powered by a separate hydraulic pump to generate immense spreading force. These are ideal for:
- High-pressure flange connections
- Large diameter flanges
- Situations requiring exact control over spreading force
The key benefits of hydraulic flange spreaders include:
- Strong spreading force – Can produce a max spreading force of 16.3 tons (or 32.6 tons when used in pairs).
- Precise control – Allows for controlled separation to minimize damage to flanges and gaskets.
- Reduced operator effort – Hydraulic power eliminates manual exertion.
Choosing the Right Tool for Commercial Flange Dismantling
While not all flange spreaders are created equal, make sure your chosen flanger spreader has these key characteristics to ensure safe and efficient operation:
- Durability – Flange spreaders must be able to endure harsh industrial environments. Check that they’re constructed from forged steel or a steel alloy to handle heavy loads and resist corrosion.
- Versatility – Many spreaders offer adjustable jaws to accommodate various flange sizes. Some models also include interchangeable stepped blocks for precise gapping during separation.
- Safety features – Look for features like overload protection to prevent damage to the spreader or surrounding equipment. Safety lanyards and safety blocks can further enhance safe operation.
Apart from these core flange spreader features, you can also consider the following additional factors to help you select the right tool for the job:
- Flange size and pressure rating – Different spreaders are designed to handle various flange dimensions and pressure loads. Consider your flanges’ maximum working pressure (MWP) to ensure the spreader can handle the job.
- Space constraints – Compact flange spreaders are essential in cramped environments. These space-saving models allow technicians to operate in tight quarters, often featuring a narrow frame and short pump design for optimal leverage.
