Line pipe is a type of steel pipe that is used for transporting materials through pipelines across the country. Line pipe can be used to transport petroleum, natural gas, oil, and water. It is a durable pipe that must meet certain specifications and regulations.


 Steel line pipe has been used successfully for decades now in the transportation of gases, flammable liquids and solids. Given the high pressure levels frequently involved in the transportation of these media, steel is the optimum pipe material and it remains unparalleled in terms of safety and reliability for a long service life.


Our state-of-the-art production equipment and processes, a wide range of coating and lining systems, plus top-quality service all along fulfill our customers' individual needs and wishes in terms of safety, environmental protection and project-specific demands.
