Energy Tubulars


ENA is one of the largest producers of energy tubulars in North America, with capacity of 1.5 million tons, including ERW and seamless OCTG (“Oil Country Tubular Goods”), high-frequency welded (HFW) line pipe, and helical submerged arc welded (HSAW) pipe. We are the only fully vertically integrated North American producer offering a portfolio covering down-hole solutions through long-distance energy transmission.



ENA is the leading producer of OCTG in Canada with operations in Camrose, Calgary and Red Deer, Alberta; and Regina, Saskatchewan. In addition, we produce seamless OCTG casing from our Pueblo, CO mill, serving major energy basins across the United States. With full heat treat, threading, and finishing capabilities (including semi-premium and premium threads), ENA supplies some of the most demanding energy applications.

Key Applications: convention oil and gas, non-convention shale, thermal oil sands, geothermal, and CO2 and hydrogen storage.

HFW Line Pipe

ENA produces HFW line pipe at our Regina, Camrose and Red Deer facilities, in sizes from 3.5 inch to 24 inch OD. Line pipe is available with external polyethylene, fusion bonded epoxy and abrasion resistant coatings, as well as internal epoxy coatings.

Key Applications: gathering and transmission lines for crude oil, natural gas, CO2, and hydrogen.

HSAW (Spiral) Pipe

ENA was an early pioneer in large diameter pipe production, and we remain one of the largest suppliers in North America. With proven heavy-wall, X80 grade capability, our Regina HSAW mill is one of the most advanced facilities in North America and has supplied many of the largest pipeline projects on the continent. available with external fusion bonded epoxy and abrasion-resistant overlay coatings, as well as internal epoxy coating.

Key Applications: transmission lines for crude oil, natural gas, CO2, and hydrogen.

Evraz EVRlock

EVRlock connections are manufactured and measured to precise tolerances down to the micron, with engineered features that provide reliable service for the most challenging wells.
