When utilised in environments with high hydrogen production, such as those that produce H2S, API 5L HIC Tested NACE Line Pipe is resistant to hydrogen-induced cracking. The National Association of Corrosion Engineers' recognised specifications and guidelines are followed in the production of NACE MR0175 Seamless Pipe. Regulations for corrosion control are the focus of NACE. One such grade of pipes manufactured in this range is the NACE MR0103 Pipe. These pipes come in a variety of grades, including API 5L and others. Additionally, there are various product specification levels. Schedules 20 to XXS for Carbon Steel HIC Tested NACE Pipe are possible depending on the wall thickness and outer diameter. Wall thicknesses between 2mm and 250mm are possible. The sizes of the HIC Tested NACE Carbon Steel Pipe range from 12 inches to 24 inches. These pipes can be produced using a variety of methods, including SAW, LSAW, HSAW, and EFW. Pipes up to 100 inches in diameter can be produced using some production techniques. The pipes can be silver, black, or any other colour, and they can be polished or painted. The majority of the material in the API 5L HIC Tested NACE Seamless Line Pipe is carbon steel, and the pipes are shaped like circles. Most often, high pressure applications where free hydrogen molecules are liberated are where these pipes are used. Depending on the composition and toughness of the material, the NACE Pipe Welding requires preheating and post-weld heat treatment.

Production activities and upstream exploration are covered by NACE MR0175, "Sulfide Stress Cracking Resistant Metallic Materials for Oilfield Equipment," whereas refineries employ NACE MR0103, "Materials Resistant to Sulfide Stress Cracking in Corrosive Petroleum Refining Environments." For many metallic materials, such as alloy and low carbon steels, ss, nickel alloys, and other metallic materials, both standards give particular requirements.
