Pipe preparation device

A device for performing a plurality of operations substantially concurrently on a pipe, said pipe having a longitudinal axis and an outer circumferential surface, said device comprising:

• a first support having a support surface engageable with the outer circumferential surface of said pipe;
• a cup mounted on said first support, said cup having a circumferential side wall defining an opening oriented and sized to receive an end of said pipe when said pipe engages said first support, said circumferential side wall being engageable with said outer circumferential surface of said pipe and providing radial reinforcement thereto, said cup being rotatable about an axis of rotation substantially parallel to said longitudinal axis of said pipe;
• a second support positioned in spaced relation to said first support, one of said supports being movable toward and away from the other;
• a first tool comprising a grooving surface mounted on said second support and positioned facing said first support, said grooving surface being engageable with said outer circumferential surface of said pipe when said pipe is supported on said first support;
• a second tool mounted on said second support and positioned facing said first support, said second tool being engageable with said outer circumferential surface of said pipe substantially concurrently with said first tool, said second tool being selected from the group consisting of a marking surface, a radiusing surface, a chamfering surface and a cutting blade, said plurality of operations including forming a circumferential groove around said pipe with said grooving surface, forming a reference mark circumferentially around said pipe with said marking surface, chamfering the outer surface of said pipe with said chamfering surface, radiusing the outer surface of said pipe with said radiusing surface and cutting said pipe with said cutting blade;
• and
• said first and said second tools and said pipe being rotatable relatively to one another around said longitudinal axis to effect said plurality of operations.

A device for performing a plurality of operations substantially concurrently on a pipe, said pipe having a longitudinal axis and an outer circumferential surface, said device comprising:

• a first support having a support surface engageable with the outer circumferential surface of said pipe;
• a collar mounted on said first support, said collar having a circumferential side wall defining an opening oriented and sized to receive said pipe when said pipe engages said first support, said circumferential side wall being engageable with said outer circumferential surface of said pipe and providing radial reinforcement thereto;
• said collar being rotatable about an axis or rotation substantially parallel to said longitudinal axis of said pipe;
• a second support positioned in spaced relation to said first support, one of said supports being movable toward and away from the other;
• a plurality of tools mounted on said second support and positioned facing said first support, said tools being engageable substantially concurrently with said outer circumferential surface of said pipe when said pipe is supported on said first support, said tools including a grooving surface, a marking surface, a surface for deforming an end of said pipe and a cutting blade, said plurality of operations including forming a circumferential groove around said pipe with said grooving surface, forming a reference mark circumferentially around said pipe with said marking surface, deforming the outer surface of said pipe with said deforming surface and cutting said pipe with said cutting blade;
• and
• said tools and said pipe being rotatable relatively to one another around said longitudinal axis to effect said plurality of operations.

A device for performing at least one of a plurality of operations on a pipe, said pipe having a longitudinal axis and an outer circumferential surface, said device comprising:

• a first support having a support surface engageable with the outer circumferential surface of said pipe;
• a collar mounted on said first support, said collar having a circumferential side wall defining an opening oriented and sized to receive said pipe when said pipe engages said first support, said circumferential side wall being engageabie with said outer circumferential surface of said pipe and providing radial reinforcement thereto, said collar being rotatable about an axis of rotation substantially parallel to said longitudinal axis of said pipe;
• a second support positioned in spaced relation to said first support, one of said supports being movable toward and away from the other;
• and
• at least one tool mounted on said second support and positioned facing said first support, each tool and said pipe being rotatable relatively to one another around said longitudinal axis to effect said operation, each tool being engageable with said outer circumferential surface of said pipe when said pipe is supported on said first support, each tool being independently selected from the group consisting of a grooving surface, a marking surface, a radiusing surface and a chamfering surface, said plurality of operations including forming a circumferential groove around said pipe with said grooving surface, forming a reference mark circumferentially around said pipe with said marking surface, radiusing the outer surface of said pipe with said radiusing surface and chamfering the outer surface of said pipe with said chamfering surface.
