What is API Spec 5L PSL 2?
API 5L PSL2 Line Pipe is a pipe product manufactured in compliance with Product Specification Level 2 of the American Petroleum Institute (API) standards. It is specifically engineered for demanding oil and gas transmission environments. Compared to PSL1, it imposes stricter controls on chemical composition, mechanical properties, non-destructive testing (NDT), and fracture toughness, ensuring safe and reliable operation in high-risk, high-demand applications such as sour corrosive environments, low-temperature service, high-pressure conditions, and critical trunk lines.
Baohui is a professional supplier of API 5L PSL2 Line Pipe, specializing in the production and global supply of high-performance pipes for demanding oil and gas applications. We focus on PSL2 grade products designed for sour service, low-temperature environments, and high-pressure transmission, ensuring stricter quality control with mandatory impact testing, tighter chemical composition, and comprehensive non-destructive inspection.

Frequently Asked Questions (FAQ)
Q1: What is the difference between X52 PSL1 and PSL2?
A: PSL2 has mandatory Charpy Impact testing, stricter limits on sulfur & phosphorus, maximum tensile strength limits, and mandatory Carbon Equivalent control for weldability. PSL1 does not have these requirements.
Q2: Can you supply pipe for sour service according to NACE MR0175?
A: Yes. We produce and certify PSL2 pipe with the "S" suffix (e.g., X65QS) that is fully compliant with NACE MR0175/ISO 15156 for resistance to Sulfide Stress Cracking (SSC). HIC testing can be performed upon request.
Q3: What is your lead time for PSL2 line pipe?
A: For standard grades and sizes, we target 30-45 days ex-works. For large-volume projects or special grades (X80+), lead time is 45-60 days. We maintain strategic stock for popular X60/X65 grades.
Q4: Do you provide pipes with external/internal coatings?
A: Absolutely. We offer a full range of coatings: External (FBE, 3LPE, 3LPP) and Internal (FBE, Epoxy). We work with certified coating partners or can supply bare pipe for your nominated coater.
Q5: What documentation comes with the shipment?
A: You receive a complete Mill Test Certificate (MTC) per EN 10204 Type 3.1, including chemical analysis, mechanical test results (tensile, impact), hydrostatic test report, and NDT reports. Origin certificates and commercial documents are also provided.
