Steel grades for Pipe piling

Pipe piles and tubular piles have many advantages, compared with other construction materials.

1. Easy and stable to connect with other steel materials and components
Tubular piles can connect with tubular piles themselves by different kind of interlocks, and also be connect with sheet piles, H beams, etc. This make pipe piles the most popular materials in constructions.
2.More easy transport handling
You can use truck to delivery, use bulk vessel to carry. Very easy to transport, no extra care is needed.
3. Good for the environment:
39 percent of all steel in China is recycled each year. 30% of steel is produced in facilities that use recycled materials ,which means they don’t emit CO2.This environmental consciousness is becoming a greater and greater concern across all industries.
4. Easily spliced into longer lengths or cut into shorter length.
Pipe piling can be produced in very long length, without butt welding.
5. Ideal for hard driving conditions, specially hard ground
Pipe piles perform better than most other materials in environments that experience a lot of shock and vibration. Its resistance to shock makes it a great choice for water mains under roadways and other transportation applications that face a lot of rolling and bouncing tires
6. High strength and good roundness
Pipe piling have very high tensile strength, which means pipe piling can withstand the more amount of pressure than other construction materials. A greater carrying capacity makes it more cost-effective.

API Steel Pipes

European steel pipes

1) According to API 5L: For each reduction of 0.01% below the specified maximum carbon content, an increase of 0.05% above the specified maximum manganese content is permissible, up to a maximum of 1.50% for grade X42 to X52, 1.65% for X56 to X65 and 2.00% for X70
2)Unless otherwise agreed, the sum of the niobium and vanadium contents shall be ≤ 0.06 %.
3) Unless otherwise agreed
