1、Structure of Galvanized Welded Pipe:
Seamless pipe is formed by drawing a solid billet over a piercing rod to create the hollow shell. As the manufacturing process does not include any welding, seamless pipes are perceived to be stronger and more reliable. Historically seamless pipe was regarded as withstanding pressure better than other types, and was often more easily available than welded pipe.

6、Galvanized Welded Pipe Images：
- Q: How do you inspect steel pipes for defects?
- The inspection of steel pipes for defects requires a methodical approach that combines visual examination, non-destructive testing (NDT) techniques, and specialized equipment. The following are the typical steps undertaken to inspect steel pipes for defects: 1. Visual Examination: Commence by visually inspecting the external surface of the pipe, searching for any visible indications of defects, including cracks, dents, or corrosion. Particular attention should be given to welds, joints, and areas prone to stress or damage. 2. Ultrasonic Testing (UT): Ultrasonic testing is commonly employed to identify internal defects in steel pipes. This technique involves transmitting ultrasonic waves into the pipe and then interpreting the echoes received. Any irregularities in the internal structure, such as cracks or voids, can be identified and analyzed. 3. Magnetic Particle Inspection (MPI): MPI is a widely utilized technique for detecting defects on or near the surface, such as cracks, seams, or other discontinuities. This method involves applying a magnetic field to the pipe and subsequently applying ferromagnetic particles (usually iron-based) to the surface. These particles accumulate and form visible indications at areas where magnetic flux leakage is caused by defects. 4. Eddy Current Testing (ECT): Eddy current testing is suitable for detecting surface and near-surface defects in conductive materials like steel. This technique involves inducing an alternating current into the pipe and monitoring changes in the electrical currents induced by any present defects. These changes are then analyzed to identify and evaluate the defects. 5. Radiographic Testing (RT): Radiographic testing is conducted by exposing the steel pipe to X-rays or gamma rays and capturing radiographic images of the pipe. This technique allows for the detection of internal defects, such as cracks, porosity, inclusions, or variations in wall thickness. The radiographic images are subsequently examined for any indications of defects. 6. Dye Penetrant Inspection (DPI): DPI is a method used to identify defects on the surface of steel pipes. It involves applying a liquid dye to the surface, which penetrates into any surface cracks or flaws. After sufficient time for the dye to seep in and react, excess dye is removed, and a developer is applied to draw out the dye from the defects, rendering them visible. 7. Pressure Testing: Pressure testing entails pressurizing the steel pipe to a predetermined level and monitoring for any pressure drops or leaks. This test ensures that the pipe can withstand the required pressure without any structural defects. It is worth noting that the choice of inspection technique depends on various factors, such as the type of defect being sought, the size and characteristics of the pipe, and the specific industry standards and regulations. Inspection professionals with expertise in NDT methods and equipment are typically employed to ensure precise and dependable results.
- Q: Can steel pipes be used for underground cable conduits?
- Yes, steel pipes can be used for underground cable conduits. Steel pipes have high strength and durability, making them suitable for protecting and housing cables underground. They provide excellent protection against external elements and can withstand a wide range of environmental conditions. Additionally, steel pipes offer good resistance to corrosion, ensuring the longevity of the cable conduit system.
- Q: What are the different methods of pipe lining for steel pipes?
- Pipe lining for steel pipes can be done using various methods, each with its own unique features and benefits. These methods include: 1. Spray lining: A specially formulated coating is sprayed onto the inside of the steel pipe, creating a protective barrier against corrosion and chemical damage. Spray lining is a popular choice for smaller pipes due to its cost-effectiveness and quick installation. 2. Cured-in-place pipe lining (CIPP): This method involves inserting a flexible liner into the steel pipe and then curing it in place using steam or hot water. CIPP restores the pipe's structural integrity and is commonly used for larger pipes without the need for excavation. 3. Slip lining: By inserting a slightly smaller diameter pipe into the existing steel pipe and filling the space between them with cementitious material, slip lining rehabilitates pipes with minor defects and extends their lifespan. 4. Fold-and-form lining: A flexible liner is inserted into the steel pipe and expanded to its diameter using mechanical or hydraulic processes. The liner is then folded and formed to fit the pipe's contours before being cured in place. Fold-and-form lining is suitable for pipes with irregular shapes or bends. 5. Coating lining: A protective coating is applied to the inside surface of the steel pipe using spraying, brushing, or rolling methods. This coating acts as a barrier against corrosion and chemical damage and is commonly used for large pipes or those in harsh environments. Each method has its own advantages and disadvantages, and the selection will depend on factors such as pipe diameter, condition, budget, and project requirements. Consulting with a professional pipe lining contractor is crucial to determine the most suitable method for a specific steel pipe rehabilitation project.
- Q: What is the difference between steel pipe and tubing?
- Steel pipe and tubing are both used in various applications, but they have distinct differences. The primary difference between steel pipe and tubing lies in their shape and dimensions. Steel pipe is typically round in shape and has a hollow interior. It is manufactured in a variety of sizes and thicknesses to accommodate different pressure and temperature requirements. Steel pipe is commonly used in construction, plumbing, and oil and gas industries for conveying fluids or gases. On the other hand, steel tubing can come in various shapes, including round, square, and rectangular. Unlike steel pipe, tubing is often measured by its outside diameter and wall thickness. Steel tubing is commonly used in structural applications, such as building frames, automotive components, and machinery. Another difference between steel pipe and tubing is their manufacturing process. Steel pipe is typically made from solid steel billets that are heated and stretched to create a seamless or welded tube. Tubing, on the other hand, can be produced through various methods, including hot or cold rolling, welding, or extrusion. In terms of strength and durability, both steel pipe and tubing offer excellent qualities. However, the specific requirements of the application will determine which one is more suitable. Steel pipe is often chosen for high-pressure or high-temperature applications, while steel tubing is preferred for structural purposes or when a specific shape is required. In summary, the main difference between steel pipe and tubing lies in their shape, measurement methods, and manufacturing processes. While steel pipe is round and measured by its inside diameter, tubing can come in various shapes and is typically measured by its outside diameter. Both steel pipe and tubing are widely used in different industries, but the choice depends on the specific application and requirements.
- Q: How are steel pipes used in the construction of dams?
