Inspection of API pipe before leaving the yard.

API 5L Carbon Steel Line Pipe

Materials used in line pipe manufacturing include carbon steel, plastic, and composite materials, with steel being predominant due to its strength and durability.  Line pipe is manufactured in various grades and specifications to meet the requirements of different pressures, temperatures, and corrosive conditions.

The line pipe industry is characterized by stringent quality and safety standards, as the pipes are critical components that must prevent leaks and ruptures to protect the environment and ensure the safety of the public. Overall, the line pipe industry plays a vital role in supporting global energy infrastructure, contributing to economic development, and ensuring the efficient and safe transport of essential resources.

OCTG - Oil drilling operation on the drilling rig platform in the oil and gas industry.

OCTG (Oil Country Tubular Goods)

The OCTG industry is a critical sector that supports the oil and gas industry by providing the necessary tubular products used in the exploration, drilling, and production of oil and gas wells. These goods include a wide range of high-quality steel tubes, specifically casing, tubing, and drill pipe. Each of these products serves a distinct purpose in the oil and gas extraction process: 

Casing is used to line the inside of a drilled well to protect and support the well stream against external pressures and contaminants. Tubing transports the oil and gas from the well to the surface. Drill Pipe is a heavy, seamless pipe that rotates the drill bit and circulates drilling fluid. It forms the drill string that helps in drilling to extract oil or gas. 

The OCTG industry is global in nature, with significant activities in oil and gas producing regions around the world, including North America, the Middle East, Russia, and parts of Asia and Africa.

  • Specifications: ASTM F2619, ASTM D2513, ASTM F714

  • SDR (Density Ratio): SDR 7 through 32

  • Resin: Domestic 4710

  • Applications: Gas, Oil and Water

Constructon of bridge over river using steel pipe pilings.

Structural Steel 

A wide range of applications rely on the use of structural steel pipe for strength and stability in a variety of sizes and grades depending on the needs of the project.  Common uses of structural steel can be structural supports, pilings, bridges, road bore casings, dock piles, marine foundations, construction…etc.  ASTM A252 is a standard specification for welded and seamless steel pipe for structural use. This application plays a critical role in creating stable foundations for various projects ensuring safety and durability.

Specifications

  • O.D. (Outside Diameter): 2” – 48” non-API

  • Process (Manufacturing): ERW, HSAW and DSAW

  • Grade: ASTM A53 – Grade B

  • Applications: Marine, Civil and Structural Piling
