Product Details of Cangzhou Yulong Steel Co., Ltd.
Cangzhou Yulong Steel Co., Ltd. is a prominent enterprise in the steel industry, specializing in the production and export of a wide range of high - quality steel products. Our products are well - received in domestic and international markets, known for their excellent quality, diverse specifications, and strict compliance with various industry standards.
1. Steel Pipes
1.1 Seamless Steel Pipes
- Production Capacity and Inventory: As one of our core products, seamless steel pipes are produced with an annual capacity of a significant amount, and we maintain a stock of over 500,000 tons all year round. This large - scale inventory ensures that we can meet the urgent needs of customers promptly.
- Product Range: We produce seamless steel pipes in a wide range of sizes, covering different diameters and wall thicknesses. The outer diameters can range from a small size suitable for precise applications to large diameters for industrial and infrastructure projects.
- Industry Standards: These seamless steel pipes are manufactured in strict accordance with multiple international and domestic industry standards, such as API 5L, API 5CT, ANSI, ASME, EN, DIN, GOST, JIS, KS, and BS. This strict compliance guarantees the high - quality performance of our products in various working conditions, whether it is for oil and gas transportation, mechanical engineering, or other industrial uses.
1.2 Spiral Steel Pipes
- Manufacturing Process: Our spiral steel pipes are produced using advanced manufacturing techniques. The steel strips are continuously wound and welded in a spiral shape, ensuring high - strength and uniform quality throughout the pipe.
- Applications: They are widely used in large - diameter pipeline projects, such as water supply and drainage systems, sewage disposal pipelines, and some low - pressure gas transportation pipelines. Their large - diameter and high - strength characteristics make them suitable for such large - scale infrastructure applications.
- Quality Assurance: Similar to seamless steel pipes, spiral steel pipes also adhere to strict quality control procedures. We conduct comprehensive inspections during the production process, including non - destructive testing methods like ultrasonic testing and radiographic testing, to ensure that each pipe meets the required quality standards.
1.3 Straight - Seam Steel Pipes
- Product Features: Straight - seam steel pipes are characterized by their straight and smooth inner and outer surfaces. They offer good dimensional accuracy and can be customized according to the specific requirements of customers.
- Diverse Applications: These pipes find applications in a variety of fields, including construction, automotive manufacturing, and general machinery. In construction, they can be used as structural components or for plumbing systems. In the automotive industry, they may be used in the manufacturing of vehicle frames or exhaust systems.
- Quality Standards: We ensure that straight - seam steel pipes meet the relevant industry standards. Our production facilities are equipped with advanced equipment for precise welding and shaping, and strict quality inspection is carried out at each production stage to guarantee product quality.
2. Flanges
2.1 Types of Flanges
- Forged Flanges: Our forged flanges are made from high - quality steel billets through a forging process. This process enhances the mechanical properties of the flanges, making them more durable and suitable for high - pressure and high - temperature applications. They are available in different materials, such as carbon steel, alloy steel, and stainless steel, to meet the needs of various industries.
- Slip - on Flanges: Slip - on flanges are designed for easy installation. They can be easily slipped onto the pipe end and then welded in place. This type of flange is widely used in pipelines where quick installation and disassembly may be required. We produce slip - on flanges in accordance with international standards, ensuring proper fit and connection with pipes.
- Weld Neck Flanges: Weld neck flanges are known for their excellent stress - bearing capacity. They have a long tapered neck that provides a smooth transition from the flange to the pipe, reducing stress concentration. These flanges are commonly used in high - pressure and high - integrity pipeline systems, such as in the oil and gas industry.
-
2.2 Standards and Export Markets
- Compliance with Standards: All our flanges comply with a series of international standards, including EN1092 - 1, ANSI, ASME, DIN, JIS, KS, BS, and GOST. This ensures that our products can be seamlessly integrated into projects around the world, meeting the strict requirements of different countries and regions.
- Global Reach: Relying on our efficient supply chain management, our flanges are exported to more than 50 countries and regions globally. These include the Middle East, where they are used in large - scale oil and gas projects; Southeast Asia, for various industrial and infrastructure developments; Russia, for its extensive pipeline networks; Europe, with its high - end manufacturing and construction industries; Mexico and South America, for their growing industrial and energy sectors; and Africa, in support of its infrastructure building boom.
3. Pipe Fittings
3.1 Varieties of Pipe Fittings
- Elbows: We produce elbows in different angles, such as 45 - degree, 90 - degree, and 180 - degree elbows. These elbows are used to change the direction of pipelines. They are available in seamless and welded versions, and can be made from various materials, including carbon steel, stainless steel, and alloy steel.
- Tees: Tees are essential for branching pipelines. Our tees are designed to ensure smooth flow transition at the junction. We offer different types of tees, such as equal tees (where all three connections have the same diameter) and reducing tees (where one or two of the connections have a smaller diameter).
- Crosses: Crosses are used when four pipelines need to be connected at a single point. Our crosses are precision - manufactured to ensure proper alignment and connection of the pipelines. They are made with high - quality materials to withstand the pressure and flow conditions in the pipeline system.
- Reducers: Reducers are used to connect pipes of different diameters. We produce concentric reducers (where the centerlines of the inlet and outlet pipes are the same) and eccentric reducers (where the centerlines are offset). These reducers are designed to minimize pressure loss during the flow transition.
-
3.2 Quality Control and Applications
- Quality Control: Each pipe fitting undergoes strict quality control procedures. We use advanced manufacturing techniques and inspection equipment to ensure dimensional accuracy, material quality, and welding integrity. Non - destructive testing methods, such as magnetic particle testing and liquid penetrant testing, are used to detect any potential defects.
- Applications: Our pipe fittings are widely used in various industries. In the oil and gas industry, they are used in pipelines for transporting oil, gas, and refined products. In the power generation industry, they are used in steam pipelines and cooling water systems. In the chemical industry, they are used in pipelines carrying corrosive chemicals, where the corrosion - resistant properties of our stainless - steel and alloy - steel pipe fittings are highly valued.
-
In conclusion, Cangzhou Yulong Steel Co., Ltd. is committed to providing customers with high - quality steel pipes, flanges, and pipe fittings. Our products not only meet the strictest international standards but also offer excellent performance and reliability. We look forward to establishing long - term partnerships with customers around the world, jointly promoting the development of the steel industry.
