Clamping Ring Parts


Clamping rings from Auwell’s product line is the mechanism that join/duct 2 pipes together linearly by clamping the pre flared pipe edges.

The clamping ring is formed by a flat steel bar to the desired shape and diameter.  It consists 2 half rings, the closing side is connected by a screw bolt or hinge, the opening side also has 2 ways of assembly - the screw mechanism or quick release (fast connector) mechanism. For both assembling methods, the ring can be tightened and adjusted to the desired tightness.

In general, the diameter of clamping rings range from 80mm to 630mm, the profile of the rings can be U shaped, V shaped, or custom made upon clients’ request. The thickness of the rings range from 1mm to 3mm. If the pipeline is for liquid transportation, rim seals will be used, the seal material can be NBR or silicone, with a maximum pressure of up to 4.5bar.

Before Clamping
After clamping

The half clamping ring parts are assembled with a saddle (stamping parts), hinges, and fast connectors by butt welding followed by hand welding for reinforcement. Before assembling the 2 halves, for carbon steel or stainless steel parts, zinc plating and shot blasting may be applied respectively upon request.
