API 5L X70 contains two product specification levels: PSL1 and PSL2. API 5L X70 pipe is known for its non-combustibility and at the same time, it also has high corrosion resistance. API 5L Gr X70 covers both seamless and welded (ERW, SAW) types of fabrication, and the products covered are all suitable for oil and gas transmission.
Advantages of API 5L X70 Pipe:
- High dynamic tearing resistance
- High low temperature impact toughness
- Low ductile-brittle transition temperature
- Acid service suitability
- High strength
- Long lasting
