What is the water supply seamless pipes?
Water supply seamless pipe is a general seamless pipe used to transport water and other fluids, and the implementation standard is GB/T8163-2008. Due to its good sealing and pressure resistance, it is widely used in municipal water supply, water conservancy projects and other fields. It is a key material to ensure the reliable operation of the city's lifeline.
Because under the condition of equal circumference, the circle area is the largest, more fluid can be transported by circular tube, and the circular cross section is subjected to more uniform force when subjected to internal or external radial pressure. Therefore, the vast majority of water supply seamless pipes are round tubes. Of course, there are also special-shaped tubes according to special needs.
Advantages of water supply seamless pipes
1. High strength and high toughness: Seamless steel pipes are made of a whole piece of steel without welds, so they have higher strength and toughness, can withstand higher water pressure and external pressure, and are not prone to rupture.
2. Good sealing: Seamless steel pipes have no seams, which reduces the risk of leakage and ensures the efficiency and safety of the water delivery process.
3. Excellent corrosion resistance: Water pipelines are in a humid or corrosive environment for a long time. Seamless steel pipes can effectively resist corrosion and extend their service life through anti-corrosion treatment.
4. Safe water quality: Seamless steel pipes are made of stable materials and will not pollute the water quality, ensuring the hygiene and safety of drinking water.
5. Smooth inner wall: The inner wall of the water supply seamless pipe is very smooth, which greatly reduces the resistance of the fluid during transportation. Water can flow more smoothly in the pipe, thereby improving water transportation efficiency, reducing energy consumption during transportation, and saving energy costs.
6. Economical and practical: Although the initial purchase cost of water supply seamless pipes may be slightly higher than some ordinary pipes, they have a long service life and low maintenance costs. From the perspective of long-term use, they can save users a lot of money and have a high cost-effectiveness. They are an economical and practical choice for water pipelines.
Main materials of water supply seamless pipes
No. 20 steel: This is a commonly used high-quality low-carbon carbon steel with a carbon content of about 0.2%. It has moderate strength, good toughness, plasticity and weldability, a tensile strength of 253-500MPa, and an elongation of ≥24%. It is widely used in water delivery seamless pipes and is suitable for water delivery systems with general pressure and water quality conditions, such as daily water supply pipelines for urban residents. It can meet the needs of long-term stable water delivery and is easy to process and install.
Q345: It is a low-alloy high-strength steel with a tensile strength of 470-660MPa and a yield strength of about 345MPa. It has good weldability and is not prone to defects such as cracks and pores during welding. It also has strong corrosion resistance, and the added alloy elements make it better resistant to erosion by water and impurities in water. It also has good low-temperature toughness and is suitable for water delivery projects in low-temperature environments, such as outdoor water delivery pipelines in northern winter. It is often used in water delivery projects that require high strength and corrosion resistance, such as large industrial water delivery systems, long-distance water delivery pipelines, etc.
