Specification and Types of Carbon Steel Pipe

Carbon steel pipes are manufactured using many different techniques that produce a pipe with various characteristics. The carbon content present in a carbon steel pipe can be up to 2.1 percent of the weight of the total alloys. Any increase in the carbon percentage in the alloy used to make a carbon steel line pipe would increase the metals’ hardness and tensile strength properties. The Black Carbon Steel jacketed pipe would lose its ductile properties, even with a rise in the percentage of carbon.

What are the various specifications of Carbon Steel Pipes?

Carbon Steel Pipes are available in a wide range of sizes of about 1/2” NB to 36” NB.

They are manufactured in many standards, namely, ASTM A/ASME SA 106 Grade A, B, C; ASTM A/ASME SA 53 Grade A, B; API 5L – PSL 1 Gr. A, B, X42, X46, X52, X56, X60, X65, X70; ASTM A/ASME SA 333 Grade 1, 6.

The Carbon steel pipes are designed in the thickness range of SCH 40, SCH 80, SCH 160, and so on. These CS pipes find their applications in industries such as Power Generation (Nuclear/Thermal), Oil Refineries, Petrochemicals, Boiler Equipment, Steel, Sugar, Pressure Vessels, and General Engineering Purposes. Most carbon steel pipes have been produced from Grade B steel for years, which has a minimum yield strength of 35,000 psi.

United Forge Industries provides a wide range of carbon steel pipes tailored for the mining sector, including seamless and welded options such as ERW, EFW, LSAW, and SSAW pipes.

What are the different types of Carbon Steel Pipes?

The Carbon Steel pipes are manufactured in various types, as given below:

Carbon Steel Seamless Pipes – it contains more carbon and iron in its composition. Depending on the grade, trace amounts of silicon, manganese, and copper are permitted in varying quantities. Therefore, the Carbon Steel Seamless Pipe material is stronger and is extremely resistant to stress. In heavy-duty facilities, these features make the pipes applicable.

Carbon Steel ASTM A335 Pipes – The ASTM A335 P11 Seamless Pipe consists of carbon steel with a minimum tensile strength of 415MPa and a minimum yield strength of 205MPa. The material has high durability and high resistance to wear and tear. They are made up of Carbon, manganese, phosphorus, sulphur, silicon, chromium, and molybdenum. The composition of the ASME SA335 Grade Crome Pipe gives it the characteristics of strength, strength, stiffness, wear resistance, hardness, hot hardness, and corrosion resistance.

Carbon Steel Fabricated Pipes – offer high durability, corrosion resistance, and tensile strength. The Carbon Steel Fabricated Pipes are used in various industries such as Oil & Gas Industry, Chemical Industry, Metallurgical Industry, Energy Industry, Ships Industry, Desalination Industry, Food Industry, and Pulp and Paper Industry.

Carbon Steel Welded Pipes – are used in high-pressure conditions. In a range of industries, such as the transport of water and waste, the oil and gas industries, high-pressure applications, and chemical manufacturing, carbon steel pipes are commonly used.

Carbon Steel ERW Pipes – have various features like Lightweight, Corrosion resistance, structured appropriately, Precision engineered, intricate detailing, Economical, and more. These ERW pipes are used in Ship Building, Automobile, Boilers & Pressure Vessels, Railways, Oil & Petro Chemicals, Coal & Mining, Transmission Towers, and General & Heavy Engineering.

Carbon Steel LSAW Pipes – has some fine features such as easy installation, seamless finish, Rustproof, and more. As these LSAW pipes are expensive, they are not widely used in lower value non-energy applications such as water pipelines.

ASTM A106 Pipe: ASTM A106 pipe refers to carbon steel pipes made through hot rolled or cold drawn seamless methods. This standard covers seamless pipes designed for high-temperature services, making them suitable for conveying fluids like water, oil, gas, and slurry. Given its heat-resistant properties, ASTM A106 pipe is vital in mining industries.

ASTM A53 Pipe: ASTM A53 pipe encompasses both welded and seamless steel pipes, typically in carbon black material and occasionally hot-dipped galvanized (zinc-coated). It serves as a fundamental pipe material, with similar performance and pricing to ASTM A106B or API 5L B pipes. Sometimes, pipes marked with all three standards are referred to as “Three standards steel pipe.” A53 pipe is widely used in mining and slurry services due to its versatility and reliability.

So, these were the types and specifications of Carbon Steel Pipes. We hope this blog helped you understanding both the aspects of CS pipes in a better way.
