Ticona (Florence, Ky., USA) reports that its Celstran continuous fiber-reinforced thermoplastic composite (CFR-TP) was used in the new Fiberflex-11 composite pressure pipe from Composite Fluid Transfer (Kilgore, Texas, USA). The pipe recently won a JEC Americas 2013 innovation award in the Pipes & Water Management category. Recipients include Ticona, Composite Fluid Transfer and Valeron Strength Films (Houston, Texas), which supplies a protective outer wrap.
Fiberflex-11 pipe (10.5 inches/267 mm inner diameter, 11.1 inches/282 mm outer diameter) is rated at 250 lb/in2 (psi) operating pressure and incorporates Celstran CFR-TP continuous fiberglass reinforced HDPE thermoplastic composite tape, which is wound around and heat consolidated to a specially designed, extruded thin-wall HDPE thermoplastic liner. A 30-ft/9.1m-section of Fiberflex -11 pipe weighs only 128 lb/58 kg and can be easily lifted by two people in the field, versus the same length of 12-inch/305 mm HDPE SDR 9 pipe that weighs 655 lb/297 kg.
The pipe system is said to offer several robust coupling/connector options, including a two-bolt, patent-pending, quick-coupling design. It is designed specifically for general water transport infrastructure, including distribution systems, oil and gas operations, hydraulic fracturing feed water and produced water, large irrigation systems, tank farm operations and dewatering systems. A key strength cited is the adaptability of the product to meet fluid transfer market demands outside the oil and gas industry.
This composite pipe reportedly can be easily altered to operate at higher pressures, in tougher environments, at higher temperatures, with larger diameter, and with any type of piping system connections. For example, the burst pressure of the finished pipe can be increased as necessary from the current design, which delivers a burst pressure of 500 lb/in2 (psi).
