Introduction
This document provides a detailed technical and commercial overview of our EN 10216-2 certified seamless steel tubes and pipes, specifically designed and manufactured for critical pressure applications. Our products are engineered to meet the most demanding international standards, ensuring reliability, safety, and performance in high-temperature and high-pressure environments. This overview covers dimensional ranges, material specifications, manufacturing processes, applications, quality assurance, and commercial terms.

1. Product Specification and Dimensions
We supply a comprehensive range of seamless tubes and pipes conforming to the European standard EN 10216-2. This standard specifies the technical delivery conditions for seamless tubes made of non-alloy and alloy steels with specified elevated temperature properties, intended for pressure equipment.

Our manufacturing capabilities cover an extensive size range to meet diverse project requirements:

• Outside Diameter (OD):   17.2 mm to 168.3 mm

• Wall Thickness (WT):   1.0 mm to 15.0 mm

• Maximum Length:   Up to 19 meters, allowing for efficient installation and minimizing welds in long pipeline sections.

This dimensional flexibility ensures we can provide suitable products for a wide array of applications, from compact heat exchangers to large-scale boiler systems.

2. Material Grades and Standards Compatibility
Our proficiency extends beyond a single standard, offering remarkable material versatility. While EN 10216-2 is our core certification, we are adept at producing tubes equivalent to various international specifications, providing our global clientele with a reliable single-source solution.

• Primary Standard:   EN 10216-2

• Key Material Grades Supplied:   We supply a wide spectrum of grades tailored for specific service conditions:

  • Carbon Steel Grades:   P235TR1/2, P235GH, ST37, ST45.8, STB340, A106 Gr. A/B/C, A179, A192.

  • Alloy Steel Grades:   15MoG, 15CrMoG, 16Mn, 13CrMo4-5, and others for enhanced strength and temperature resistance.

• Equivalent Standards Supplied:   Our products can be manufactured to meet ASTM (A178, A179, A192, A210, A106), DIN (17175, 1629), JIS (G3454), and other internationally recognized standards upon request.

3. Advanced Manufacturing and Finishing
Quality is ingrained in our manufacturing process. We employ state-of-the-art cold drawing and cold rolling techniques to achieve superior dimensional accuracy, excellent surface finish, and enhanced mechanical properties.

• Process:   Cold Drawn (CD) and Cold Rolled. These cold working processes result in tubes with precise tolerances, smooth internal and external surfaces, and increased strength.

• Surface Treatment:   To ensure optimal performance and prevent corrosion during transit and storage, we offer various surface finishes including oiling, varnishing, passivation, and phosphating. Shot blasting is also available for superior paint adhesion.

• End Preparation:   Tubes are supplied with plain ends or beveled ends (prepared for welding) as required, and are protected with plastic caps to prevent damage.

4. Primary Applications and Usage
Our EN 10216-2 seamless tubes are indispensable components in industries where failure is not an option. They are specifically designed for use in:

• Heat Transfer Equipment:   Ideal for boilers, superheaters, heat exchangers, and condensers where efficient thermal conductivity and pressure integrity are paramount.

• Power Generation:   Widely used in high, medium, and low-pressure boiler systems in fossil fuel and biomass power plants.

• Petrochemical and Process Industries:   Suitable for manufacturing pipelines, pressure vessels, reactors, and other equipment handling volatile or corrosive media under pressure.

• General Engineering:   Applied in the construction of heavy-duty steel structures and mechanical components requiring high strength-to-weight ratios.

5. Quality Assurance and Certification
We operate a stringent quality management system certified to ISO 9001, ensuring consistent product quality from raw material to final dispatch. Our comprehensive inspection and testing protocol includes:

• Non-Destructive Testing (NDT):   Every tube undergoes rigorous inspection, which may include Hydraulic Testing (to verify pressure integrity), Ultrasonic Testing (to detect internal and surface flaws), and X-ray Testing for critical applications.

• Third-Party Inspection (TPI):   We fully support and facilitate inspections by major international agencies such as TÜV, SGS, Bureau Veritas (BV), and Lloyd's Register.

• Documentation:   We provide full traceability with Mill Test Certificates (MTCs) conforming to EN 10204 3.1 or 3.2 standards.

6. Commercial Terms and Logistics
We are committed to facilitating smooth and secure international transactions.

• Payment Terms:   We offer flexible payment options to accommodate our clients' needs, including Letter of Credit at Sight, L/C 180 Days, Telegraphic Transfer (T/T), Documents against Payment (D/P), Open Account (OA), and Western Union.

• Packaging:   Tubes are meticulously packaged to prevent damage during ocean freight. Options include bundling with steel straps, protection in plastic bags, and secure wooden cases for added protection.

• Shipment:   We primarily ship from the world-class Shanghai Port in China, ensuring efficient logistics and reliable scheduling for global delivery.
