RTP Linepipe is a spooled, ready-made pipeline system used for applications where a corrosion resistant, high pressure pipeline is required. The patented three-layer design is contrasted from a thermoplastic liner, helically wrapped continuous high-strength fiber reinforcement and an external thermoplastic jacket. The liner acts as a corrosion resistant bladder, the fibers provide the structural integrity of the pipeline, and the jacket protects the load-bearing fibers.

•The inner liner, which serves as a conduit for the transmission fluid and/or gas, is made of high density polyethylene (HDPE) making it immune to corrosion.

•The middle layer comprised of helically wound, dry fiberglass fibers which provide the pipe’s structural integrity.

•The outer jacket is a protective barrier made of high density polyethylene (HDPE). The standard linepipe is supplied with a black jacket, which provides a minimum of 20 years protection against exposure to ultraviolet (UV) light. White THE Linepipe is available for applications which require low heat absorption, and also provides a minimum of 20 years UV protection. A yellow jacket is often used by the utilities industry and is available as a custom order.

•THE Linepipe has a maximum operating temperature of 60°C or 140°F.

•THE Linepipe is the high temperature series and is available in 2”, 3” and 4” sizes with a 600 ANSI pressure rating at a maximum operating temperature of 82°C or 180°F.



Advantages



THE Linepipe’s three-layer construction is unique and has the following advantages:

•The reinforcement layers are not encased in a thermosetting matrix and are therefore flexible, avoiding potential micro-cracking or over-straining of a matrix material.

•THE Linepipe is very durable and easy to handle.

•The simplicity of construction reduces the manufacturing costs providing an economic alternative to traditional steel or fiberglass pipeline systems.

•The liner ensures that the pipeline is immune to corrosion and eliminates the need for inspections and costly corrosion inhibitor programs.

•The continuous, long-length spools facilitate fast and easy installation with fewer connections.





•ASTM F2686-10 – THE RTP Linepipe is accepted as an ASTM International Standard as specified in “Standard Specification for Glass Fiber Reinforced Thermoplastic Pipe”.

•API (American Petroleum Institute) - OUR products are designed, qualified, and manufactured in accordance with API RP 15S, “Recommended Practice for the Qualification of Spoolable Reinforced Plastic Line Pipe”.

•ASME – OUR Flanges are compliant with the requirements of ASME B16.5, “Pipe Flanges and Flanged Fittings”.

•ISO 9001:2008 – Our core manufacturing facility meets the requirements of ISO 9001:2008, “Quality Management Systems - Requirements”.

•CSA (Canadian Standards Association) – RTP products meet the requirements of CSA Z662-07, “Oil and Gas Pipeline Systems”, which covers the design, construction, operation, and maintenance of oil and gas industry pipeline systems.

•ERCB (Energy Resources Conservation Board) – governing body in Alberta, Canada. ◦The ERCB allows RTP Linepipe applications to be processed as routine for fresh water, salt water, multiphase, crude oil/LVP, and natural gas service (including sour service). Directive 056 confirms the suitability of THE RTP Linepipe for gas applications up to the CSA Z662-07 limit of 9930 kPa and for other types of applications up to maximum pressure rating.
