API 5L Grade B Pipe │ PSL1 vs PSL2 │ Schedule & Weight Chart │ Supplier Exporter India

Q: What is the difference between API 5L Grade B PSL1 and PSL2?

PSL2 adds tighter chemistry limits, mandatory Charpy impact testing, full-body NDE, and complete traceability versus PSL1 standard requirements.

Q: Is API 5L Grade B pipe seamless or welded?

API 5L Grade B is available in both seamless and welded (ERW, LSAW, SSAW) forms depending on size and project specification.

Q: What schedules are available for API 5L Grade B pipe?

All standard schedules are available: SCH 10 through SCH 160, STD, XS, and XXS. Custom wall thicknesses can be sourced on request.

Tensile Strength (min)	60,200 psi / 415 MPa	60,200 psi / 415 MPa (max cap applies)
Charpy Impact Testing	Not mandatory	Mandatory at specified temperature
Non-Destructive Examination	Not mandatory for all	Full-body NDE mandatory
Traceability / Documentation	Basic MTR required	Full heat and pipe traceability
Sour Service (NACE MR0175)	Not suitable by default	Suitable when ordered with SR option
Offshore Applications	Typically not specified	Preferred / often required
Typical Projects	Onshore distribution, water, general service	Export pipelines, sour gas, deepwater, LNG

Oil & Gas Pipeline Applications for API 5L Grade B Pipe

API 5L Grade B line pipe is engineered for demanding transmission and distribution environments. Below are the primary application sectors and the corresponding service considerations.

Application	Service Notes
Cross-Country Transmission Lines	Long-distance oil and natural gas pipelines. PSL2 preferred for higher operating pressures and fault-tolerance requirements.
Gathering Systems	Field gathering networks connecting wellheads to processing facilities. ERW and seamless both used depending on local specification.
Distribution Networks	City gas distribution and water reticulation where moderate pressures apply. PSL1 typically acceptable.
Oil Refineries	Process piping within refinery boundaries. High-temperature and high-pressure suitability required. Cross-reference with ASTM A106 Gr B for elevated temperature service.
Petrochemical Plants	Fluid transfer lines in chemical processing. Corrosion inhibitor coating and NDE documentation typically required.
Sour Service (H2S)	PSL2 with SR annexure, NACE MR0175 compliance, and hardness restriction to HRC 22 maximum. Contact Amardeep Steel for sour service supply package.
Water Transport	Potable water, irrigation, and slurry transport pipelines. Internal lining or coating typically specified.
Power Generation	Boiler feedwater and cooling water piping circuits in thermal and combined-cycle power plants.
Mining	Slurry, tailings, and process water lines. Abrasion-resistant lining may be added for slurry service.

For higher-strength line pipe grades, Amardeep Steel also supplies API 5L X52 PSL2 Carbon Steel Pipes, X60, X65, and X70 grades for high-pressure long-distance applications.

Frequently Asked Questions: API 5L Grade B Pipe

1. What is the difference between API 5L Grade B PSL1 and PSL2?

PSL1 covers standard chemistry and strength. PSL2 adds tighter chemistry, mandatory Charpy impact testing, full-body NDE, hardness limits, and complete heat traceability for critical and sour service.

2. Is API 5L Grade B pipe seamless or welded?

Both seamless and welded (ERW, LSAW, SSAW). Seamless suits NPS 16 and below in high-pressure service. LSAW and SSAW are standard for large-diameter transmission pipelines above NPS 16. See our API 5L Seamless Steel Pipes page.

3. What schedules are available for API 5L Grade B pipe?

All schedules are available: SCH 10, 20, 30, 40 STD, 60, 80 XS, 100, 120, 140, 160, and XXS. Custom wall thicknesses can be sourced to project specification on request.

4. What is the ASTM equivalent for API 5L Grade B pipe?

Closest equivalents are ASTM A53 Grade B for seamless and welded general service, and ASTM A106 Grade B for seamless high-temperature pressure service. API 5L governs pipeline transmission.

5. Can API 5L Grade B pipe be used in sour service?
