RTP tube technology reinforced with carbon steel strips

Comply with provisions of API 17J, applications of offshore and mining pipelines, where the additional armor jacket is needed for protection and impact resistance.
Introduction

Carbon Steel Tape Reinforced RTP Pipe Technology

The pipeline has a good resistance of outside ring pressure and impact, applied for offshore and mining.

The flexible pipe with the carbon steel tape reinforcement is a very mature technical solution to increase the pipe pressure resistance and impact proof. The spooled pipe is frequently used both as flowlines and risers in the oil and gas industry for more than 30 years.

The steel armored flexible pipe uniquely combines the best features of plastic and steel, high strength, corrosion resistance and flexible and durability. It is suitable for a variety of installation methods – trenching, plowing, surface, pipe rehabilitation, horizontal directional drilling, shallow water and more. With less transportation, handling equipment, and labor-work, the installation of the pipe can save 40% to 80% time and 35% to 65% less costly than jointed steel pipe. Because it has superior corrosion resistance and enhanced flow characteristics, the reinforced pipe also delivers operations and maintenance savings for superior value across the project life cycle.
