3PE API 5L 10 Inch Anti-Corrosion Coating Polyurethane Insulated Steel Pipe

● Product Overview: The Ultimate Solution for High-Durability Pipeline Transportation

YTDR Group's 3PE API 5L 10 Inch Anti-Corrosion Coating Polyurethane Insulated Steel Pipe is a high-end integrated pipeline product integrating corrosion resistance, thermal insulation and pressure bearing. Adhering to the API 5L international standard, the product uses high-quality steel as the base material, and is equipped with a 3PE three-layer anti-corrosion coating and polyurethane (PU) thermal insulation layer. It perfectly solves the pain points of pipeline corrosion, heat loss and poor pressure resistance in harsh working conditions. It is widely used in oil and gas, municipal heating, chemical industry and other key fields. With excellent performance and reliable quality, it has become the first choice of global purchasers for pipeline projects.

The core competitiveness of the product lies in the perfect combination of 3PE anti-corrosion technology, API 5L high-strength steel base and polyurethane thermal insulation layer. The 10-inch specification (outer diameter 273mm) is a conventional and widely used model, which can meet the needs of medium and large flow pipeline transportation. The product has passed strict quality testing, and key indicators such as corrosion resistance, thermal insulation performance and pressure bearing capacity are far higher than industry standards, ensuring a service life of more than 50 years.

● Technical Specifications: Core Parameters at a Glance

● Advantages--What Purchasers Care About Most

● Super 3PE Anti-Corrosion Protection: Adopt the three-layer composite structure of "fusion-bonded epoxy powder (FBE) + copolymer adhesive (AD) + high-density polyethylene (PE)". The FBE bottom layer (thickness > 100μm) has strong adhesion and chemical inertness; the middle adhesive layer (170~250μm) realizes seamless bonding between layers; the outer PE layer (2.5~3.7mm) resists mechanical damage and environmental erosion. The coating peeling strength is ≥100N/cm, which can effectively resist acid, alkali, salt, soil microorganisms and seawater corrosion, and is suitable for pH 2~12 harsh medium environment .

● API 5L High-Strength Base Material:The base pipe strictly complies with API 5L standard, optional steel grades include L245, L360, L415, X80, etc. The 10-inch pipe has a wall thickness range of 6mm~20mm, yield strength ≥245MPa, tensile strength ≥415MPa, and can withstand a maximum working pressure of 15MPa. The weld adopts double-sided submerged arc welding process, and 100% ultrasonic flaw detection ensures no defects, which is suitable for high-pressure medium transportation such as oil and gas .

● Efficient Polyurethane Thermal Insulation:The polyurethane insulation layer has a thermal conductivity of ≤0.024W/(m·K), and the thermal loss rate is only 25% of that of traditional pipes. It can effectively maintain the temperature of the transported medium (suitable for -30℃~80℃ working environment), and is especially suitable for heating pipelines and high-temperature medium transportation projects. The insulation layer is closely combined with the 3PE anti-corrosion layer, with good waterproof and anti-aging properties .

● Convenient Construction and Installation: The product is prefabricated in the factory, and the on-site construction only needs welding and connection, which shortens the construction period by 50%. The pipe has good low-temperature impact resistance, no cracking in -30℃ low-temperature impact test, and is suitable for construction in cold northern regions and permafrost areas. The pipe end reserves 150mm non-coating area, which is convenient for welding and subsequent repair .

● Economical and Durable:The 50-year long service life greatly reduces the frequency of pipe replacement and maintenance cost (maintenance cost is reduced by more than 40% compared with traditional pipes). The product has high material utilization rate (up to 95%以上), and the comprehensive cost performance is far higher than that of single anti-corrosion or single insulation pipes .

● Customer Reviews: Real Feedback from Global Partners

The quality and service of our 3PE API 5L 10 Inch Anti-Corrosion Coating Polyurethane Insulated Steel Pipe have been highly recognized by customers in Europe, Asia, Africa and other regions. Here are some real feedbacks:

● Ivan, Procurement Director of a Russian Energy Company: "We used YTDR's 3PE API 5L 10-inch polyurethane insulated steel pipes in the Siberian natural gas transportation project. The local temperature is as low as -30℃ in winter, but the pipes have no cracking or corrosion after 2 years of operation. The thermal insulation effect is very good, which ensures the normal transportation of natural gas. The technical team of YTDR also sent professionals to the site for installation guidance, which is very professional and responsible ."

● Zhang, Engineering Manager of a Municipal Heating Company in China: "Our urban heating network renovation project adopted YTDR's 10-inch 3PE anti-corrosion polyurethane insulated steel pipes. Compared with the original old pipes, the heat loss is reduced by more than 30%, and the heating effect of residents is significantly improved. The product delivery is timely, and the after-sales team regularly returns to visit and inspect the pipeline operation status, which saves us a lot of maintenance trouble. We will continue to cooperate with YTDR in subsequent projects ."

● Ahmed, Technical Director of a Middle Eastern Petrochemical Enterprise: "The chemical medium in our refinery is highly corrosive, and the traditional pipes need to be replaced every 2-3 years. Since we used YTDR's 3PE API 5L 10-inch steel pipes, the pipeline has been operating stably for 4 years without any leakage or corrosion. The product fully meets the API 5L standard and our harsh working conditions. The professional technical support and perfect after-sales service of YTDR make us very satisfied."
