Mineral and slurry pipe is for the line pipe that is applied in mining industries. A slurry pipeline is designated to transmit ores (Iron, Coal materials), or industry mining waste, we call the pipeline taillings. Generally, these steel pipes are connected over 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 the slurry contained different materials some with abrasive properties, so the pipe could be coated with 3PE, and FBE layers to be against corrosion.

Both carbon steel pipes seamless or welded could be used for the transmission of the slurry. So there is a wide range of materials and standards available options to suit 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 is 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 its performances and prices are also similar to ASTM A106B, or API 5L B. (We saw some pipes that these three standards marked, called “Three standards steel pipe” ). So we say A53 pipe also is widely used in mining and slurry services.

To increase the resistance of steel pipe in a corrosion environment, Karisma offers different types of coating systems to protect against corrosive and abrasion breaks.

• 3PE coated, 3-layer Polyethylene coating.
• FBE coated, Fusion bonded epoxy coating.
• Zinc coated, Hot dipped galvanized steel pipe, cold electric galvanized.
• Solid, CRA, Clad and lined pipes, Cladding, and lining alloy steel material on the carbon steel material.
