PHI’s Model DF is a high-production tube and pipe end finishing unit, allowing the production of up to 600 double lap flares per hour. The machine is operated by a single lever which activates the two steps required to form a double flare. No electricity is required. All operations are pneumatically powered.
The Model DF is a double-lap flaring machine which produces a double thickness flare. It will also produce a single-thickness flare and an upset bead.
The machine forms double-lap flares to precise 37° and 45° dimensions. Single flares are also done with precision and within specifications — every time. All flares are within the tolerance of SAE 37° and 45°, MS 33583, AND10078/JIC specifications, and upset beading is within the tolerance of specification AND10060, all subject to material hardness and wall thickness limits.
About Double Flaring
Double-lap flares provide added-strength joints which are more resistant to fatigue and provide a better seal than single-thickness flares.
Double-lap flares formed by PHI machinery and tooling are free of cracks and pitmarks. The joint is also designed so that the inside surface of the flare has a larger diameter than the inside diameter of the tube or pipe and, therefore, does not interfere with flow characteristics of the system.
Typical Applications
Thin-wall tubing connections that are subject to shock, vibration, or high internal pressures such as automobile brake lines and critical aircraft hydraulic lines.
