The Mathey Dearman Sturdi Clamp is a chain clamp ideal for schedule 40 and below pipe alignment and reforming
Common Characteristics
Originally invented in 1930, Mathey Dearman offers the Sturdi Clamp as a lighter duty version of the Mathey Dearman Double Jackscrew pipe chain clamp.
One clamp can fit up a variety of sizes of pipes 10" to 36" (273 mm to 914 mm) diameter., elbows, tees, flanges end caps and most other pipe fittings (using the level and support device purchased as an accessory).
The Mathey Dearman Sturdi Clamp is available in carbon steel chain or stainless steel version. All Mathey Dearman Sturdi Clamps feature stainless steel jackscrews, jackbars and main blocks. The high rise jackbars and main block provide the strength to reform the pipe either side of the weld gap to eliminate “Hi-Lo”, whilst enabling the welder to weld the entire circumference of the pipe with the clamp in situ.
Features and advantages
- Precision alignment - The double jackbars, spaced around the outside diameter of the pipe, provide concise alignment and reforming of the internal or external diameters of both pipes within 0.5mm
- Reformability - Reforms pipes on both sides of the weld joint to schedule 40 pipe and aligns any wall schedule of pipe, elbows, tees and other fittings
- Adaptable - The chain clamp can be used to align, and reform elbows, tees and other fittings that a cage clamp can not manage. One chain clamp covers the range of eight cage clamps
- High rise independent jackbars - Double jackscrew 'high rise' jackbars have extra clearance enabling easy access with welding torch/rod. Each jackscrew has independently pivoting feet to cope with uneven surfaces
- Wide range - One chain clamp covers a wide range of pipe sizes
- Safe - Elbows, tees and other fittings can be held safely and securely in place during alignment with the level and support device
