The Sturdi Clamp by Mathey Dearman is available in carbon steel chain or stainless steel version. All Dearman 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 situations where multiple cage clamps would usually be required.

-
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 0.5 mm.
-
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 cannot 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.
