SSAW (Spiral Welded) steel pipes are widely used in various industries for fluid transportation, especially in the oil, gas, and construction sectors. The classification of SSAW steel pipes is based on different standards that govern their production and use, ensuring their safety and performance in various applications. Below is an overview of the key standard classifications for SSAW steel pipes.
Standard Classification of SSAW Steel Pipes:
- Spiral Welded Pipe (SY5036-83) for Pressurized Fluid Transportation
This type of SSAW pipe is primarily used for transporting oil and natural gas. It is designed to withstand high pressures, making it ideal for long-distance pipeline systems.
- Spiral Seam High-Frequency Welded Steel Pipe (SY5038-83) for Pressurized Fluid Transportation
This pipe is manufactured using high-frequency welding techniques, which give it excellent strength and plasticity. It is easy to weld and machine, making it suitable for carrying pressurized fluids efficiently.
- Spiral Welded Pipe (SY5037-83) for General Low-Pressure Fluid Transmission
Used mainly for transporting low-pressure fluids such as water, gas, air, and steam, this pipe is produced using double-sided automatic submerged arc welding or single-sided welding. It is suitable for low-pressure delivery systems.
Current General Standards for SSAW Steel Pipes:
- SY/T5037-2000
Also known as the ministerial standard, this is the spiral submerged arc welded steel pipe standard for ordinary fluid transportation pipelines.
- GB/T9711.1-1997
A Chinese national standard, it applies to pipes used for oil and gas industry transportation. It ensures that pipes meet the strict requirements for industrial use.
- API-5L
Issued by the American Petroleum Institute, this standard covers pipeline steel pipes and is divided into two levels: PSL1 and PSL2. These classifications specify different quality requirements for pipes used in the oil and gas sectors.
- SY/T5040-92
This standard refers to spiral seam submerged arc welded pipes for pile foundations, commonly used in construction projects that require deep foundations.
In summary, SSAW steel pipes are classified based on various standards to meet the demands of different industries, whether for transporting fluids under high or low pressure or for structural support in construction projects.
