China National Building Materials Group Corporation (CNBM) was established in 1984 with approval from the State Council, and then became a Central Enterprise under direct supervision of State-owned Assets Supervision and Administration Commission of the State Council in 2003.
Upholding the philosophy of “Making Best Use of Resources to Serve Construction”, and vigorously carrying out such strategies as “technical innovation”, “internationalization of building materials”, and “building strength with talents”, CNBM is the largest comprehensive building materials industry group in China that integrates scientific research, manufacturing and logistics into one entity, and consists of four business platforms, i.e. industry, technology, complete set of equipment, and trading & logistics. As of the end of 2009, CNBM’s total assets exceeded RMB 110 billion, with 100,000 employees, and 20 companies under direct management with 100% share control or majority control, among which 6 were listed companies, including 2 overseas listed.
CNBM practices the parent-subsidiary management system, and is one of those wholly state-owned enterprises carrying out the pilot trial of Board of Directors system and innovation system. As the strategic center, decision center, resources center, and policy & culture center, our Group exercises its right as a contributor. Whereas, our sub-groups functioning as business platforms, are mandated to construct the profit center based on their core competences to enlarge brand awareness and increase market share.
- Q:Is the cast iron pipe buried in need of antiseptic treatment? What kind of anticorrosive materials are used?
- It must be antiseptic. Usually hot asphalt brush painted two times, winding glass fiber cloth two road, cross construction.
- Q:Are ductile iron pipes suitable for use in cooling water systems?
- Yes, ductile iron pipes are suitable for use in cooling water systems. They offer excellent strength, durability, and corrosion resistance, making them ideal for transporting water at varying temperatures. Additionally, their flexibility allows them to withstand pressure and temperature changes, ensuring long-lasting and reliable performance in cooling water applications.
- Q:Are ductile iron pipes suitable for underground applications?
- Indeed, underground applications are well-suited for ductile iron pipes. Renowned for their durability, strength, and resistance to corrosion, these pipes emerge as an excellent option for installations that lie beneath the surface. Their ability to withstand immense loads, ground shifts, and external pressure further solidifies their appropriateness for burial underground. Moreover, given the challenges associated with access and maintenance in underground scenarios, the fact that ductile iron pipes boast a lifespan of over 100 years becomes invaluable. In conclusion, the reliability and suitability of ductile iron pipes for underground applications are underscored by their robustness and longevity.
- Q:Can ductile iron pipe be used for underground applications?
- Yes, ductile iron pipe can be used for underground applications. Ductile iron pipe is known for its strength and durability, making it suitable for various underground applications such as water and sewage systems, gas pipelines, and irrigation systems. Its high resistance to corrosion and external loads makes it a reliable choice for underground installations where long-term performance and structural integrity are important factors. Additionally, ductile iron pipe's flexibility allows it to withstand ground movement and settle without cracking or breaking, making it a suitable option for areas prone to seismic activity.
- Q:What is the expected flow capacity of ductile iron pipes?
- The expected flow capacity of ductile iron pipes can vary depending on various factors such as pipe diameter, length, internal roughness, and hydraulic gradient. However, generally speaking, ductile iron pipes have a high flow capacity due to their smooth internal surface and sturdy construction. They are capable of handling substantial volumes of water or other fluids efficiently and reliably.
- Q:What are the different joint restraint systems available for ductile iron pipe?
- There are several different joint restraint systems available for ductile iron pipe. These systems are designed to prevent movement and separation of the pipe at the joints, ensuring a secure and leak-free connection. Some of the common joint restraint systems for ductile iron pipe include: 1. Mechanical Joint Restraint: This system consists of a mechanical joint adapter and a restraining gland that provides axial restraint. The joint adapter is bolted to the pipe, while the restraining gland is bolted to the adjacent pipe or structure, preventing any movement. 2. Push-on Joint Restraint: In this system, a push-on joint is used along with a restraining gland that is bolted to the pipe or structure. The gland provides axial restraint by gripping the pipe and preventing it from moving. 3. Flex-Ring Joint Restraint: This system utilizes a flexible rubber ring that is installed inside the pipe's bell. The ring provides radial restraint by expanding against the pipe, ensuring a tight and secure connection. 4. Harness Joint Restraint: This system consists of a harness that is wrapped around the pipe and connected to a restraining gland. The harness provides both axial and radial restraint, keeping the pipe in place and preventing any movement. 5. Grip-Lock Joint Restraint: This system utilizes a wedge-shaped restraint that is inserted into the pipe's bell. The wedge expands and locks into place, providing both axial and radial restraint. 6. Restrained Joint System: This system incorporates a combination of mechanical and flexible joint restraints. It typically includes a mechanical joint adapter, a flexible joint restraint, and a restraining gland, providing both axial and radial restraint. These joint restraint systems are designed to meet specific application requirements and are often specified by engineers based on factors such as pipe diameter, operating pressure, and soil conditions. Each system has its own advantages and limitations, and the selection depends on the specific project needs and constraints.
- Q:What is the expected roughness coefficient of ductile iron pipes?
- The expected roughness coefficient of ductile iron pipes can vary depending on various factors such as pipe diameter, age, and condition. However, in general, the roughness coefficient for ductile iron pipes is typically around 0.01-0.015 mm. This value represents the average roughness of the internal surface of the pipe and is used in hydraulic calculations to determine the flow characteristics and pressure losses within the pipe network. It is important to note that these values are approximate and can vary based on specific pipe conditions and applications.
- Q:Are ductile iron pipes susceptible to external loading or pressure?
- Ductile iron pipes, just like any other material, are susceptible to external loading or pressure. They possess a certain level of strength and tolerance to endure external forces. However, excessive external loading or pressure can result in the deformation or failure of these pipes. To avoid any harm caused by external loading, it is crucial to ensure proper installation and support of ductile iron pipes. Furthermore, the design and engineering of the pipeline system should take into account the expected external loading and pressure to guarantee the pipes' effectiveness in handling the anticipated conditions. Regular inspections and maintenance play a vital role in detecting and resolving issues associated with external loading or pressure that may arise over time.
- Q:What does ductile iron pipe "K" mean?
- 1 、 pipe fittings are K type, T type, etc.;2 wall thickness registration symbol. For example, according to the pipe quality standards GB/T13295-K9, which is the wall thickness ofK=9* (DN/1000+0.5)
- Q:What is the external coating used in ductile iron pipes?
- The external coating commonly used in ductile iron pipes is a protective layer made of either cement mortar or polyethylene.
