DIN30670 HDPE Coated API 5L SSAW Steel Pipe

DIN 30670 HDPE Coated API 5L SSAW Steel Pipe is a high-performance pipeline solution engineered for demanding onshore and offshore applications. By combining the structural integrity of API 5L Spiral Submerged Arc Welded (SSAW) steel pipes with the superior corrosion resistance of High-Density Polyethylene (HDPE) coatings compliant with DIN 30670 standards, this product offers an optimal balance of mechanical strength, durability, and longevity. It is specifically designed for the transportation of oil, natural gas, water, and other fluids in harsh environmental conditions.

Manufactured in strict accordance with ‌API Spec 5L‌ (PSL1/PSL2), ensuring global compatibility and reliability in the oil and gas industry.

Spiral Submerged Arc Welding (SSAW) allows for the production of large-diameter pipes with high dimensional accuracy and consistent weld quality.

Coating Structure:‌ Typically utilizes a multi-layer system (often 3LPE structure compatible with DIN 30670 requirements) consisting of:

‌Fusion-Bonded Epoxy (FBE) Primer:‌ Provides excellent adhesion to the steel surface and cathodic disbondment resistance.

‌Adhesive Layer:‌ Bonds the epoxy primer to the polyethylene outer layer.

‌HDPE Outer Layer:‌ Offers robust mechanical protection against soil stress, impact, and chemical corrosion.

‌Performance Features:‌

‌Temperature Resistance:‌ Suitable for continuous operating temperatures from -40°C to +80°C (depending on specific coating type N or S as per DIN 30670).

‌Mechanical Strength:‌ High resistance to indentation, impact, and abrasion during handling, transportation, and installation.

‌Chemical Stability:‌ Excellent resistance to soil chemicals, acids, alkalis, and saltwater corrosion.

‌Electrical Insulation:‌ High dielectric strength ensures effective cathodic protection synergy.

‌Superior Corrosion Protection:‌ The HDPE coating acts as a formidable barrier against moisture and electrolytes, significantly extending the pipeline's service life beyond 50 years in buried or submerged conditions.

‌High Mechanical Integrity:‌ The SSAW manufacturing process provides uniform strength along the spiral weld, while the HDPE coating protects against backfill damage and rock impingement.

‌Cost-Effectiveness:‌ SSAW production is efficient for large diameters, reducing material costs compared to seamless pipes for low-to-medium pressure applications, while the durable coating minimizes long-term maintenance expenses.

‌Global Compliance:‌ Meets both American Petroleum Institute (API) standards for pipe body performance and European (DIN) standards for coating quality, making it ideal for international EPC projects.

‌Oil & Gas Transmission:‌ Long-distance crude oil and natural gas pipelines (onshore and offshore).

‌Water Supply:‌ Municipal water transmission mains and sewage force mains.

‌Industrial Pipelines:‌ Transport of slurry, industrial wastewater, and other corrosive fluids.

‌Piling Projects:‌ Used as structural piles in marine and land construction where corrosion resistance is critical.
