1Structure of Seamless Pipe: 

Seamless pipe possesses a hollow section and without seam around the strip steel. It is produced with solid bar or steel ingot by perforating machine. Since the facture process does not include any welding, seamless pipes are  stronger and more durable the welding pipes. We believe that seamless pipe has better pressure resistance and security than other classifications, and was usually more easily available than welded pipe.

Q: Are steel pipes suitable for potable water supply?
Yes, steel pipes are suitable for potable water supply. They are durable, have a long lifespan, and can withstand high pressure. Additionally, steel pipes are resistant to corrosion and provide a reliable and safe option for transporting potable water.
Q: How are steel pipes used in the transportation of fluids?
Steel pipes are commonly used in the transportation of fluids due to their high strength and durability. They are used in various industries, including oil and gas, water supply, and sewage systems. Steel pipes are ideal for fluid transportation as they can handle high pressure and are resistant to corrosion. They are used to transport liquids and gases over long distances, ensuring a safe and efficient flow of fluids.
Q: Can steel pipes be used for underground fire hydrants?
No, steel pipes are not typically used for underground fire hydrants. Underground fire hydrants are usually constructed using ductile iron pipes as they provide greater strength, durability, and resistance to corrosion, ensuring reliable water supply during emergencies.
Q: Are steel pipes suitable for underground sewage systems?
Yes, steel pipes are suitable for underground sewage systems. They are durable, strong, and resistant to corrosion, making them a reliable choice for carrying sewage underground. Additionally, steel pipes have a long lifespan and can withstand the pressure and weight of the surrounding soil, making them a suitable option for underground sewage systems.
Q: Can steel pipes be used for water supply networks?
Yes, steel pipes can be used for water supply networks. They are commonly used for water distribution due to their durability, strength, and corrosion resistance. However, proper coating and maintenance are essential to prevent rusting and ensure the longevity of the steel pipes in water supply systems.
Q: How can steel pipes be protected from corrosion?
Steel pipes can be protected from corrosion through various methods. One common method is the application of protective coatings. These coatings act as a barrier between the steel and corrosive elements in the environment. The most widely used protective coating for steel pipes is epoxy, which provides excellent resistance to corrosion. Other coatings such as polyethylene and polyurethane can also be used depending on the specific application and requirements. Another effective way to protect steel pipes from corrosion is by cathodic protection. This technique involves the use of sacrificial anodes or impressed current systems to prevent corrosion. Sacrificial anodes, typically made of zinc or aluminum, are attached to the steel pipes. These anodes corrode instead of the steel, sacrificing themselves to protect the pipes. Impressed current systems, on the other hand, use a direct electrical current to counteract the corrosion process. Regular maintenance and inspection are crucial in the protection of steel pipes from corrosion. Monitoring the condition of the coatings, checking for any signs of damage or deterioration, and promptly addressing any issues can help prevent corrosion from occurring or spreading. Additionally, implementing proper drainage systems to avoid the accumulation of moisture around the pipes can further protect them from corrosion. Lastly, environmental factors should be taken into consideration when protecting steel pipes from corrosion. This includes mitigating exposure to corrosive substances, such as acids or chemicals, and ensuring proper ventilation and airflow to prevent the buildup of moisture and humidity. By implementing a combination of these protective measures, steel pipes can have an extended lifespan and maintain their structural integrity.
Q: What's the difference between hot dip galvanizing and cold galvanizing? Which kind of galvanizing method is good?
There are two kinds of hot dip galvanizing, zinc plated and non galvanized. The flowers must be hot-dip galvanized, without flowers, similar to galvanized.

Q: How are steel pipes manufactured?
Steel pipes are typically manufactured through a process called seamless or welded pipe manufacturing. In the seamless process, a solid steel billet is heated and pierced to create a hollow tube, which is then stretched and rolled to the desired size and shape. In the welded process, steel sheets are formed into a pipe shape and welded along the seam. These pipes are then further processed and finished before use in various industries.
Q: What are the different testing methods used for steel pipes?
There are several testing methods used for steel pipes to ensure their quality and reliability. Some of the commonly used testing methods include: 1. Non-destructive Testing (NDT): NDT methods such as ultrasonic testing, magnetic particle inspection, and liquid penetrant testing are used to detect any surface or subsurface defects in the steel pipes without causing any damage to them. 2. Mechanical Testing: Mechanical testing involves conducting various tests to evaluate the mechanical properties of steel pipes, including tensile strength, yield strength, elongation, hardness, and impact resistance. These tests help determine the structural integrity and performance of the pipes. 3. Hydrostatic Testing: This method involves subjecting the steel pipes to high-pressure water to check their ability to withstand the expected operating conditions. Hydrostatic testing is performed by filling the pipes with water and pressurizing them to a predetermined level for a specified duration. Any leakage or deformation in the pipes is detected during this test. 4. Dimensional Inspection: This testing method ensures that the steel pipes meet the specified dimensional requirements. It involves measuring the diameter, wall thickness, length, and other critical dimensions of the pipes to verify compliance with the applicable standards or specifications. 5. Visual Inspection: Visual inspection is a basic method used to assess the external appearance of steel pipes. Trained inspectors visually examine the pipes for any surface defects, such as cracks, corrosion, or irregularities in shape or finish. 6. Chemical Analysis: Chemical analysis is performed to determine the composition and elemental content of the steel pipes. It helps ensure that the pipes are made from the correct grade of steel and meet the required chemical composition standards. 7. Metallographic Examination: Metallography involves examining the microstructure of steel pipes under a microscope to assess their quality and integrity. It helps identify any internal defects, such as grain boundaries, inclusions, or improper heat treatment, that may affect the overall performance of the pipes. By utilizing these testing methods, manufacturers and inspectors can ensure that steel pipes meet the necessary quality standards and are suitable for their intended applications.
