Differences between ISO 3183 PSL1 LSAW pipeline and PSL2

LSAW (straight seam submerged arc welding) pipelines under ISO 3183 standard are divided into PSL1 and PSL2 according to the product specification level. The two show different characteristics and advantages in multiple dimensions. The following is a clear and orderly explanation

ISO 3183 PSL1 LSAW pipeline:
This level of pipeline follows the basic quality requirements and is suitable for conventional oil and gas transportation scenarios. Its chemical composition and mechanical properties meet the basic standards. Although non-destructive testing is not mandatory, the cost is relatively low and the production cycle is short. It is an ideal choice for projects with limited budgets or low standard requirements. The advantages of PSL1 lie in its economy and applicability, which can quickly respond to market demand while ensuring basic operational safety.

ISO 3183 PSL2 LSAW pipeline:
In contrast, PSL2 pipelines have taken a new step in quality requirements. It not only puts forward higher requirements on chemical composition and mechanical properties, but also enforces non-destructive testing of each pipe to ensure that each steel pipe meets the ultimate quality standards. In addition, the sandblasting of the pipe end improves the quality of the welded joint and further enhances the overall reliability of the pipeline. The advantages of PSL2 line pipes are its excellent durability, high safety and adaptability to extreme environments. It is the first choice for high-pressure, high-temperature or corrosive media transportation. Although its production cost and testing time have increased, in the long run, its high-quality characteristics will bring greater economic benefits and safety guarantees to users.

In summary, PSL1 and PSL2 LSAW line pipes have their own advantages. When choosing, it is necessary to make comprehensive considerations based on the specific needs, budget and operating environment of the project to ensure that the most suitable line pipe products are selected.
