Flexpipe Systems Inc (Flexpipe) has designed, tested, and manufactured a high pressure, corrosion-resistant, coiled, continuous pipeline system utilizing new and exciting engineering technologies for the Oil & Gas and Utility industries. Flexpipe Systems currently offers three product lines, with ratings up to 2068 kPa (300psi), 5171 kPa (750 psi), and 10,342 kPa (1500 psi) respectively.

Flexpipe offers 2”, 3”, and 4” sizes. The standard line pipe is supplied with a black jacket, which provides a minimum of 20 years protection against exposure to ultraviolet (UV) light. White Flexpipe line pipe is available as a special-order product for applications which require low heat absorption, and also provides a minimum of 20 years UV protection.

Flexpipe line pipe (FPLP) is manufactured at the state-of-the-art Flexpipe facility in Calgary, Alberta, Canada. FPLP is a fully patented three-layer design constructed from a thermoplastic liner (liner), helically wrapped continuous high-strength fiber reinforcement (fiber) and an external thermoplastic jacket (jacket). The liner acts as a bladder, the fibers provide strength, and the jacket protects the loadbearing fibers.

This construction is unique and has the following advantages:

• The fiber reinforcement is not encased in a thermosetting matrix and is therefore flexible, avoiding potential micro-cracking or over-straining of the matrix material.
• FPLP is very durable and easy to handle.
• The simplicity of construction reduces the manufacturing costs.
• The fiber reinforcement enables design for high-pressure applications.
• The liner ensures that the FPLP is immune to corrosion and eliminates the need for inspections.
• The continuous, long-length FPLP spools facilitate fast and easy installation with fewer connections and less disturbance to impacted parties.
• Environmental impact and soil disturbance can be reduced since FPLP can be trenched with a narrower trench and right of way than steel line pipe, or plowed in without trenching.

The design and manufacturing of FPLP is in accordance with standards and guidelines regarding qualification, quality control and testing of composite pipe and accessories. Please refer to Quality Assurance page
