Carbon Steel Pipe

Carbon steel pipe is the most common use piping material in different industries served for construction, structural, liquid transmissions for water, oil and gas. Typical carbon steel pipe material grades in API 5L Grade B, X42 to X70, ASTM A106 B, ASTM A53 B, ASTM A252 Grade 3 and ASTM A333 Grade 6 etc.

SunnySteel offers various of carbon steel pipes including seamless, welded (ERW EFW, LSAW, SSAW) steel pipes for the mining industries.

Carbon steel pipe price at 800 to 1600 USD per Metric Ton FOB China, depending on different grade and dimension.

• AWWA C-200 for steel water pipe

Carbon Steel Pipe for Mineral Slurry

Mineral and slurry pipe is for the line pipe that applied in mining industries. A slurry pipeline is designated to transmit ores (Iron, Coal materials), or the industry mining waste, we called the pipeline as taillings. And generally these steel pipes connected in a long distances. Above materials mixed with water, we call slurry. People will use pumps to transport to the final destination then water will be filtered out. Since slurry contained different materials some with abrasive properties, so the pipe could be coated with 3PE, FBE layers to against from corrosion.

Both carbon steel pipe in seamless or welded could be used for the transmission of the slurry. So there is a wide range of material and standards available options to suit for the special working conditions.

ASTM 106 pipe refers to the carbon steel pipe manufactured in hot rolled or cold drawn (rolled) seamless. ASTM A106 standard specification covers the seamless pipe that applied in high temperature services. As a result, it could used to carry the fluids (water, oil and gas, slurry), it is an important material for mining industries.

ASTM A53 pipe covers welded and seamless steel pipe, in carbon black material and some cases in hot dipped galvanized (zinc coated). This is a basic pipe material, and it’s performances and prices also similar to ASTM A106B, or API 5L B. (We saw some pipes that they these three standards marked, call “Three standards steel pipe” ). So we say A53 pipe also is widely used in mining and slurry services.

Coating types for carbon steel pipe against corrosion environments

In order to increase the resistance of steel pipe in corrosion environment, Octal offers different types of coating systems to protect against from the corrosive and abrasion break.
