Compliance with MESC and NACE Requirements

The galvanized seamless steel pipes supplied in this order fully complies with:

• MESC SPE 74/004 (2018, 2019, 1997 versions)
• NACE MR0175 for sour service environments
• HIC (Hydrogen Induced Cracking) resistance
• SSC (Sulfide Stress Cracking) resistance

This ensures that the galvanized seamless steel pipe is suitable for hydrocarbon service and harsh operating conditions.

Material Control and Chemical Composition

Haihao Group applies strict control over raw materials for every galvanized seamless steel pipes:

Key Requirements:

• Carbon Content (C) ≤ 0.23%
• Carbon Equivalent (CE) ≤ 0.43
• Sulfur Content (S) ≤ 0.01%

These limits improve weldability, toughness, and resistance to cracking in low-temperature environments.

Low-Temperature Performance

The galvanized seamless steel pipes are specifically designed for cold service conditions:

• Impact Test Temperature: -46°C
• Guaranteed impact test compliance
• Fine-grained carbon steel structure

This ensures safe operation in extreme climates and critical pipeline systems.

Inspection and Certification

Each galvanized seamless steel pipe undergoes strict inspection and documentation:

Testing & Certification:

• ✔ Material Test Certificates (EN 10204 3.1 / ISO 10474 3.1)
• ✔ Dimensional inspection
• ✔ Thread inspection (NPT compliance)
• ✔ Coating thickness and quality verification

These measures guarantee full traceability and quality assurance.

Advantages of Galvanized Seamless Steel Pipes
