Product Description

In the realm of modern infrastructure, ductile iron pipes stand as indispensable components, playing a crucial role in the seamless transportation of various fluids, such as water, gas, and sewage. Our company specializes in manufacturing ductile iron pipes that can accommodate a wide spectrum of standards and diverse (diameter sizes), ensuring that we meet the unique requirements of every project, no matter how large or small.

 

I. Versatility in Standards

 

1. Domestic Standards
   • We are well - versed in adhering to national standards like GB/T 13295. This comprehensive standard details strict requirements for the chemical composition of raw materials. For example, the carbon content in the iron used for our pipes is carefully controlled within a specific range. A proper carbon percentage is essential as it directly impacts the pipe's strength and ductility. Silicon, another key element, is also precisely regulated. It not only enhances the fluidity of the molten iron during the casting process but also contributes significantly to the final mechanical properties of the pipe.
   • In addition to GB/T 13295, we can also manufacture pipes in accordance with other domestic standards. These standards cover aspects such as dimensional tolerances, mechanical strength requirements, and surface quality. Whether it's a standard that emphasizes high - pressure resistance for gas pipelines or one that focuses on corrosion resistance for water supply systems, we have the expertise to meet them.
2. International Standards
   • Our manufacturing capabilities extend to international standards as well. For instance, we can produce pipes that comply with ISO 2531. This international standard is widely recognized in the global market. By following ISO 2531, our pipes can be seamlessly integrated into international infrastructure projects. The standard sets guidelines for the production process, from the quality of raw materials to the final inspection procedures. We ensure that our pipes meet the international benchmarks for tensile strength, yield strength, and elongation, making them suitable for use in various countries around the world.
   • We are also familiar with ASTM standards. ASTM (American Society for Testing and Materials) has a series of standards related to ductile iron pipes. These standards are highly regarded in North America and other regions. By conforming to ASTM standards, we can provide pipes that meet the specific requirements of projects in these areas. For example, ASTM A536 defines the chemical and mechanical properties of ductile iron, and we ensure that our production process adheres to these strict guidelines.

 

II. Diverse Diameter Sizes

 

1. Small - Diameter Pipes (DN40 - DN200)
   • Our small - diameter ductile iron pipes, ranging from DN40 to DN200, are ideal for a variety of applications. In residential water supply systems, these pipes are often used for the final connection from the main water line to individual households. Their smaller size allows for easy installation in tight spaces. Despite their small diameter, they are designed to withstand the internal pressure of water supply, ensuring a continuous and reliable water flow. In addition, in small - scale irrigation systems, these pipes can be used to distribute water to plants efficiently. Their corrosion - resistant properties make them suitable for use in outdoor environments, where they may be exposed to moisture and soil chemicals.
2. Medium - Diameter Pipes (DN250 - DN600)
   • The medium - diameter range, from DN250 to DN600, is widely used in commercial and industrial applications. In commercial buildings, these pipes are used for the water supply and drainage systems. Their larger diameter can handle higher water flow rates, meeting the demands of multiple floors and various facilities within the building. In industrial settings, such as factories and manufacturing plants, these pipes can be used to transport process fluids. For example, in a food processing plant, they may be used to carry water for cleaning equipment or to transport ingredients in the production process. The pipes' ability to withstand different types of fluids and pressures makes them a reliable choice for these applications.
3. Large - Diameter Pipes (DN700 - DN3000)
   • Our large - diameter ductile iron pipes, with diameters ranging from DN700 to DN3000, are the workhorses of large - scale infrastructure projects. In urban water supply systems, these pipes serve as the main trunk lines, transporting large volumes of water from treatment plants to different parts of the city. Their large cross - sectional area allows for high - volume flow, reducing the energy consumption associated with pumping water. In gas transmission networks, large - diameter pipes are used to transport natural gas over long distances. Their high - strength and gas - tight properties, as required by relevant standards, ensure the safe and efficient transmission of gas. In wastewater treatment plants, these pipes are used to collect and transport sewage from collection points to the treatment facilities.

 

III. Manufacturing Process

 

1. Raw Material Selection
   • Regardless of the standard or diameter size, we start with the careful selection of high - quality raw materials. The iron used is sourced from reliable suppliers and is tested to ensure it meets the chemical composition requirements of the relevant standard. Alloying elements are added in precise amounts to achieve the desired mechanical properties. For example, to enhance the strength of the pipe, elements like manganese may be added in a controlled manner.
2. Casting Process
   • We employ advanced casting techniques to produce pipes with consistent quality. For small - diameter pipes, we may use centrifugal casting, which ensures a uniform wall thickness. This is crucial as any variation in wall thickness can lead to weak points in the pipe. For medium and large - diameter pipes, vertical or horizontal continuous casting methods may be used. These methods allow for the production of long - length pipes with high precision. During the casting process, the temperature and speed are carefully controlled to ensure the proper solidification of the molten iron.
3. Heat Treatment
   • After casting, the pipes undergo heat treatment. This process is essential for improving the ductility and strength of the pipe. The heat treatment cycle is tailored according to the standard and the diameter of the pipe. For pipes with higher strength requirements, a more intense heat treatment may be applied. The heat treatment process helps to optimize the microstructure of the iron, making the pipe more resistant to cracking and deformation.
4. Inspection and Quality Control
   • Rigorous inspection procedures are carried out at every stage of production. Non - destructive testing methods, such as ultrasonic testing and radiographic testing, are used to detect any internal defects in the pipes. Surface inspection is also performed to ensure that the pipe has a smooth surface, free from cracks, pits, or other flaws. We have a dedicated quality control team that strictly adheres to the inspection criteria set by the relevant standards. Any pipe that does not meet the quality requirements is rejected, ensuring that only high - quality products are delivered to our customers.

 

IV. Applications in Different Industries

 

1. Water Supply Industry
   • Our ductile iron pipes, available in different standards and diameters, are widely used in the water supply industry. Small - diameter pipes are used for household connections, medium - diameter pipes for commercial and small - industrial water supply, and large - diameter pipes for main water transmission lines. The pipes' corrosion - resistant properties, in line with relevant standards, ensure a long - lasting and clean water supply. They can withstand the internal pressure of water distribution systems, providing a reliable water source for communities.
2. Gas Industry
   • In the gas industry, our pipes are used for both natural gas transmission and distribution. Pipes manufactured to meet the high - pressure requirements of gas transmission standards are used for long - distance gas pipelines. The ability of these pipes to maintain gas tightness, as per the standards, is crucial for safe gas transportation. Smaller - diameter pipes are used for local gas distribution to residential and commercial customers.
3. Wastewater Treatment Industry
   • For the wastewater treatment industry, our pipes are designed to transport sewage from collection points to treatment plants. The smooth inner surface of the pipes, as required by relevant standards, helps to prevent blockages and ensure the efficient flow of wastewater. The corrosion - resistant properties of the pipes are also important as sewage can contain various chemicals that could cause corrosion over time.
