Abstract

A pipe/fitting having an end having a modified crimp for securing both flexible ducts and pipes. Specifically, the pipe/fitting includes an end having a series of annularly disposed pipes. The modified crimp includes an outwardly facing channel in the base of the series of crimps configured to secure a flexible duct between the channel and a fastener received in the channel. The end also includes a pipe coupling system at the base of the series of crimps configured to couple a pipe to the conduit.

Abstract

A pipe and fitting coupling system includes a first pipe, a second pipe, and a joint. A receiving end of the second pipe includes a first flange, a second flange, a groove, and a sealant. The second flange extends further than the first flange. The groove is disposed at the pipe diameter and between the first flange and the second flange. The first flange has an inwardly angled face to meet the groove and the second flange has an outwardly angled face to meet the groove. The sealant is disposed in the groove to seal the plain end of the first pipe in the receiving end. The joint is formed by the cooperative alignment of the plain end being inserted into the receiving end and being sealed by the sealant.

Abstract

A roll forming apparatus including a plurality of stations each including and an upper roll and a lower roller, wherein a first number of stations are configured to form a pipe blank into a standing seam, and a second number of stations are configured to angle the seam. At least one station includes elongated top and bottom rollers for clinching the pipe blank during the roll forming process. Each elongated top roller is mounted on a pivotable shaft configured to pivot the elongated top rollers away the pipe blank to allow passage of at least one seam formed in the pipe blank.

Abstract

A crimping machine including a first shaft having a first crimping portion and a bead wheel and a second shaft having a tapered portion disposed opposite the bead wheel of the first shaft. The first and second shafts are configured to grip a pipe blank having a transverse channel including a first angle. The first and second shafts are further configured to roll the pipe blank forward while crimping a portion of the pipe blank with the first and second crimping portions and applying pressure on the transverse channel of the pipe blank. The crimping machine further has having a tapered portion disposed opposite at least a portion of the crimping portion and the bead wheel of the first shaft. The bead wheel is configured to push upon the forming shaft to bend the first angle of the transverse channel formed in the pipe blank to a second angle.
