Coupling and thread can be required according to customer requirment

Q: Is the same specification seamless steel pipe more expensive than welded pipe?: Specifications of the same kind of seamless steel pipe than welded pipe prices are generally about 30% high, large diameter difference is greater.

Q: What are the different methods of joining steel pipes for high-pressure applications?: Some of the different methods of joining steel pipes for high-pressure applications include welding, threaded connections, flanged connections, and mechanical couplings. Welding involves fusing the pipes together using heat, making it a strong and permanent connection. Threaded connections involve screwing the pipes together using threads on the ends, which can be easily assembled and disassembled. Flanged connections involve using flanges and bolts to connect the pipes, providing a secure and leak-proof connection. Mechanical couplings use mechanical devices such as clamps or compression fittings to join the pipes, allowing for quick and easy installation and removal.

Q: How can galvanized steel tubes be painted on the surface?: Suitable for galvanized base material (antirust primer), epoxy zinc yellow primer (double component), epoxy ester zinc yellow primer.Pretreatment of galvanized sheet when brushing:1, conditional, you can zinc plating phosphating treatment, or first spray a layer of phosphating primer.2, or smooth zinc plating surface sweeping treatment.3, the galvanized workpiece, galvanized pipe surface with solvent (that is, epoxy zinc yellow primer, thinner) wipe, in order to remove the workpiece crude oil protective layer, and increase cleanliness.4, two-component epoxy zinc yellow primer: in strict accordance with the proportion of paint and curing agent paint, and aging 30 minutes later, modulation suitable construction viscosity, you can spray.One component epoxy ester primer: zinc yellow construction viscosity suitable to construction of modulation, the correct construction method.

Q: How to distinguish between steel pipe and spiral pipe material?: The alloy tube can be divided into: low alloy pipe, alloy pipe structure, high alloy tube, high strength tube. Bearing tube, heat resistant acid resistant stainless pipe, precision alloy (such as cutting alloy) pipe, high temperature alloy tube, etc..

Q: What is the cost of steel pipes compared to other materials?: The cost of steel pipes compared to other materials can vary depending on factors such as size, grade, and market conditions. However, in general, steel pipes tend to be more cost-effective and economical compared to other materials like copper or PVC. Steel is a durable and versatile material that offers excellent strength and longevity, making it a preferred choice in various industries such as construction, oil and gas, and plumbing.

Q: How are steel pipes classified based on pressure ratings?: Steel pipes are classified based on pressure ratings by assigning them different schedules, ranging from Schedule 10 to Schedule 160. Each schedule represents a different maximum pressure that the pipe can withstand, with higher schedules indicating higher pressure ratings.

Q: What are the different grades of steel used for manufacturing pipes?: The different grades of steel used for manufacturing pipes include carbon steel, alloy steel, stainless steel, and duplex steel.

Q: Can steel pipes be used for irrigation pumps?: Yes, steel pipes can be used for irrigation pumps. Steel pipes are commonly used in irrigation systems due to their durability, strength, and resistance to corrosion. They can handle the high pressures and flow rates required for efficient irrigation, making them a suitable choice for connecting and transporting water from irrigation pumps.

Q: What is the difference between steel pipe and concrete pipe?: Steel pipe and concrete pipe are commonly used for various applications, but they have significant differences in material composition and properties. To begin with, the primary distinction lies in the materials utilized to manufacture these pipes. Steel pipes consist of steel, an alloy of iron and carbon. Conversely, concrete pipes are composed of a mixture of cement, aggregate (such as sand or gravel), and water. Additionally, steel pipes are renowned for their strength and durability. They can withstand high pressure, making them suitable for transporting fluids or gases under high pressure. Steel pipes also possess high resistance to corrosion, which is advantageous in environments exposed to moisture or chemicals. In contrast, concrete pipes are not as sturdy as steel pipes and are more prone to cracking or damage under high pressure. Nevertheless, they can still handle moderate pressure loads and are often employed in drainage systems or sewage applications. Another noteworthy difference is the installation process. Steel pipes are typically joined together through welding techniques like butt welding or socket welding, creating a seamless and robust connection between the pipes. Conversely, concrete pipes are often installed using rubber or gasketed joints, which are simpler to assemble and disassemble. Cost is another factor where steel and concrete pipes diverge. Steel pipes tend to be more expensive due to the higher cost of steel as a raw material and the additional labor required for welding and fabrication. On the other hand, concrete pipes are generally more cost-effective as the materials used in their production are more readily available and the installation process is simpler. In summary, the main disparities between steel pipes and concrete pipes revolve around their material composition, strength, resistance to corrosion, installation process, and cost. Steel pipes offer superior strength and durability, making them suitable for high-pressure applications and environments prone to corrosion. Concrete pipes, while not as robust, are cost-effective and commonly used in drainage systems or sewage applications.

Q: What are the different methods of protecting steel pipes from corrosion?: There are several methods of protecting steel pipes from corrosion, including: 1. Coatings: Applying protective coatings such as epoxy, polyethylene, or zinc to the surface of the steel pipes can create a barrier against corrosive elements. 2. Cathodic Protection: This method involves installing sacrificial anodes or impressed current systems to provide a protective current that counteracts the corrosion process. 3. Corrosion Inhibitors: Adding chemicals or inhibitors to the fluid or environment surrounding the pipes can reduce the rate of corrosion. 4. Internal Linings: Applying internal linings made of resin, cement, or other materials can protect the inner surface of the pipes from corrosion caused by the transported fluid. 5. Design Considerations: Implementing proper design practices like avoiding sharp bends and crevices, ensuring proper drainage, and using corrosion-resistant alloys can help prevent corrosion in steel pipes.
