Mega Rim Clamps - High Tensile Strength Reforming

Part No: D711-2632M
Mathey Dearman Mega Rim Clamp  

Mega Rim Clamp includes:

• Clamp frame
• Required number of jackscrews for the clamp size
• Flip-Up jackbars for mating pipe
• Stabilizer bars
• Level and support device attachment point
• Clamp wrench
• Parts and operating manual

FEATURES:
• EXTREME REFORMING CAPABILITY— Reforms high tensile strength pipes.
• HI-LO — Can be used on pipe out-of-round condition up
to a 2" (51mm) with out-of-round condition.
• VERSATILE—Engineered based on actual customer
applications.
• The jackbar rotates out of position for alignment, welding and grinding without removal of the clamp.

NOTE:
You will need to provide us with the following information in order to specify the Mega Rim Clamp for your application:

1. Pipe diameter (inches or millimeters)
2. Pipe wall thickness (inches or millimeters)
3. Pipe tensile strength or type material
4. Horizontal or vertical application
5. Ambient temperature


The Mega Rim Clamp aligns and reforms high tensile strength X65, X70 and X80 pipes with wall thicknesses up to 7/8" (22mm) (see chart below for tensile strengths). The clamp reforms pipe out-of-round condition up to 2" (51mm), gaining its strength from heavy-duty oval shaped side plates, latching mechanism, and flip-up jackbars for mating pipes.

The hinged flip-up jackbars, placed with precision on the clamp, can be rotated away from the primary pipe for insertion of the mating pipe, valve or fitting to facilitate welding and grinding. The independent pivoting pads of the jackscrews allow for uneven surfaces on the pipe. To avoid risk of contamination, all surfaces of the Mega Rim Clamp that come in contact with the pipe are made of stainless steel.

NOTE: Please provide us with the following information in order to specify the Mega Rim Clamp for your application.
1. Pipe diameter (inches or millimeters)

2. Pipe wall thickness (inches or millimeters)

3. Pipe tensile strength or type material

4. Horizontal or vertical application

5. Ambient temperature

All calculations based on a temperature of 72ºF (2ºC).

WARNING: Contact Mathey Dearman with pipes cladded with materials such as Inconel or Titanium. As temperature decreases below 0ºF (-18ºC), the ability of the clamp to reform the pipe wall listed will decrease sharply.
