Flange Spreader Insights
We offer a full line of innovative tools designed for making flange maintenance safer and easier. When considering a flange spreader for your application, precision and safety are paramount. Let’s review what factors you need to know.
How to Choose the Right Flange Spreader
Remember, accuracy matters. Choosing the right flange spreader ensures efficient and safe maintenance or installation.
Application Include but not limited to…
Flange facing: Resurfacing flange faces for maintenance purposes.
Pipeline maintenance and construction: For spreading pipe flanges during repair or replacement of gaskets and valves.
Pressure vessel servicing: Accessing the internals of pressure vessels for maintenance or modification.
Power plant operations: Maintenance and repair of various equipment within power plants.
Offshore platforms: Performing maintenance tasks on flanged connections in offshore oil and gas operations.
Compact Flanges: Flange Spreaders which use the bolt holes to spread a joint.
Flange Type: Identify the type of flange you’re working with (e.g., raised face, flat face, ring joint). Different flanges require specific spreader designs.
Flange Size: Measure the flange diameter accurately. This ensures compatibility with your spreader.
Pressure Class: Understand the pressure rating of your flange. Choose a spreader that can handle the required pressure.
Supervisor Records: If available, consult any existing records your supervisor may have. They might contain essential details about the flange.
Measuring Tools: If no records exist, grab your measuring tools. Old-fashioned, but effective! Measure the flange dimensions.
Gap or Gapless: Check if there’s a gap between the flanges. If yes, measure the gap size. Step Wedge Flange Spreaders require at least .20″ of a gap, depending on the model. Mini Gap Flange Spreaders require 3/32″.
Bolt Hole Size: For gapless flanges or gaps less than 3/32″, measure the bolt hole diameter.
Outside-to-Outside Distance: Measure the distance from the outer edge of one flange to the outer edge of the other.
Bolt Hole Size: If you’re removing a valve or blind, measure the bolt hole diameters.
Valve Length: Measure the length of the valve or blind itself.
Spacing: Notate and measure possible obstructions or spacing issues.
At ESI, we provide flange spreaders that empower operators to apply force with precision, ensuring controlled and measured force is used for every task, aligning with the core principles of physics for optimal results.

Key Benefits:
- Operator Safety: Prioritizes the operator’s safety with its thoughtful design.
- Enhanced Control: Offers superior control during operation, enhancing precision and efficiency.
- Simplified Operations: Tasks that were once intricate and demanding are now effortlessly manageable.
Designed initially for underwater use by divers, this flange spreader has expanded its utility to a variety of challenging environments. It proves invaluable for flanges situated in hard-to-reach areas or at towering heights. The task of transporting an 80-pound case can be formidable, and when the work site is situated 100 feet above ground, the challenge intensifies. However, the integrated pump feature is a game-changer, offering ease of operation that minimizes operator fatigue and significantly reduces the risk of accidents.

For years, maintaining flanges, especially those without gaps, was a daunting task. Traditional methods involving cranes, pulleys, and crowbars not only posed significant safety risks but also demanded an excessive amount of time and labor. Enter ZG Collet/Pin Technology – the game-changer in flange maintenance.
Safe and Efficient Operations ZG Collet Technology is engineered to provide operators with a safe and efficient solution for maintaining challenging flange joints. Innovative Design for a Firm Grip The tool’s innovative design allows you to insert the arms into the bolt hole easily. Whether you’re manually tightening or using a hydraulic pump, the collets expand seamlessly inside the bolt hole, securing a firm grip from within. This ensures a stable and reliable setup, essential for the task at hand.
