1.Product Description

API 5L carbon steel pipe is manufactured to API Spec 5L for high-pressure transmission of oil, gas, and water. Grades range from B to X80, with the number indicating minimum yield strength in ksi. Processes include SMLS, LSAW, SSAW, ERW, and EFW. Quality levels PSL1 and PSL2, with PSL2 requiring stricter chemistry, toughness, and NDT coverage. OD 10.3mm～2032mm; wall thickness and length custom-engineered.

2. Product Applications

Long-distance and subsea oil/gas trunk lines, field gathering/injection networks, refinery process piping, city gas/heating/water mains, offshore platforms, and structural steel load-bearing members.

3. Product Advantages

Grade selection matches duty: X52/X60 for medium pressure, X65/X70 standard for high-pressure trunks, X80 for wall thinning at high throughput
PSL2 grades provide excellent low-temperature toughness with verified DWTT crack arrest
Sour service series at ≤250HV10, HIC/SSC validated for H₂S environments
Low CEV reduces preheat needs, improving field welding productivity
Fully traceable with complete quality documentation per pipe
Compatible with FBE, 3LPE, 3LPP coatings; 50+ years buried service life
