What is flanging?

Pipe-flanging machines permit the joining of pipe sections without the need for costly welded flanges and the associated temporary tack welding, slag removal and x-ray inspection.

A prefabricated slip flange is placed against the assembly on an adjacent pipe section A discshaped rubber seal placed between the two formed flanges prevents any leaks. Problems in liningup bolt holes are eliminated with the use of slip flanges which rotate freely on the pipe. Standard flanges can still be used.

Typical Applications: Chemical plants, petroleum refineries, power plants, and pipelines.

See PHI’s tube and pipe end-finishing machines.

What are double-lap flares?

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 pit marks. 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.

What is beading?

Beading is a versatile end-finishing technique that can be applied to a variety of industrial applications in conjunction with an O-ring, for example, beaded joints can be used to interconnect exhaust tubes or low-pressure fuel lines.

Beads can also be used to dampen vibration in solid lines, or to increase the effectiveness of the seal when a rubber or fabric sleeve is clamped to a metal duct.

Typical applications: Low pressure air, exhaust, and liquid systems in the automotive, appliance and boating fields.

What is the tube and pipe bending process?

Tube/pipe bending is the process of bending tubes or pipes with the aid of computer-operated machines that curve segments of tubes to exact specifications. This process can be completed with cold or hot working machines. Whether the bending task is automated or done manually, the mechanical properties of the tube or pipe are usually altered during the bending process. Industries that require complex reshaping of tubes and pipes demand accurate tube bending machines. PHI has been a leading producer of precise tube forming machinery for over 50 years.

Warranty

What is PHI’s equipment warranty?

The equipment is warranted to be free from defects in material and workmanship under normal and proper usage when owned by the original Buyer. Seller’s sole obligation under this warranty is limited to replacing and repairing parts, which they may determine to be defective within the twelve (12) month warranty period. Seller will replace or repair, at its option, without charge, any part of any machine manufactured by Seller which proves to be defective in material or workmanship, provided the defective part is shipped to Seller’s factory, transportation charges prepaid, at any time within twelve (12) months from the date of shipment, and proves to be defective upon inspection by Seller. Results of ordinary wear and tear, improper operation or maintenance, or use of corrosive or abrasive materials shall not be considered a defect in material or workmanship. This warranty covers only those parts manufactured by Seller. Seller makes no warranty as to any other part, and Purchaser shall have, as to such part, only the benefit of such warranty as its manufacturer may give and which, by terms of such warranty, is available to Purchaser from the Seller. Any modifications to the equipment sold by Seller, which have not been authorized by Seller, void this warranty and any product liabilities.

If Seller repairs or replaces a part pursuant to the terms of this warranty, Seller’s warranty will not extend beyond twelve
(12) months from the original date of purchase of the machine.

In no event shall the Seller be responsible for any special, incidental, consequential or tort damages, damages arising from equipment downtime, or exemplary or punitive damages, whether resulting from loss of use, delay of delivery, loss of profits, loss of business or otherwise arising out of or in connection with the goods, the performance of the goods, or Seller’s provision of the goods or other events relating to the goods even if Seller has been advised of the possibility of such damages.
