Q:How are steel pipes protected against underground corrosion?: Steel pipes are typically protected against underground corrosion through various methods such as coating the pipes with corrosion-resistant materials like epoxy or polyethylene, cathodic protection using sacrificial anodes or impressed current systems, and regular inspection and maintenance to detect and address any signs of corrosion.

Q:Can steel pipes be used for pharmaceutical manufacturing?: Yes, steel pipes can be used for pharmaceutical manufacturing. Steel pipes are commonly used in various industries, including pharmaceutical manufacturing, due to their durability, strength, and resistance to corrosion. In pharmaceutical manufacturing, steel pipes are primarily used for fluid transportation, such as the transfer of chemicals, solvents, and other raw materials. They are also used for the distribution of process water, steam, and other utilities. Stainless steel pipes are particularly preferred in pharmaceutical manufacturing as they are highly resistant to corrosion and can withstand high temperatures and pressures. Moreover, stainless steel pipes have smooth surfaces, which prevent the accumulation of particles and facilitate easy cleaning and sterilization, essential requirements in pharmaceutical production. Overall, steel pipes are a reliable and suitable option for pharmaceutical manufacturing due to their robustness, resistance to corrosion, and ability to meet the stringent cleanliness and hygiene standards of the industry.

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:Can steel pipes be used for hydraulic systems?: Yes, steel pipes can be used for hydraulic systems. Steel pipes are commonly used in hydraulic systems due to their high strength, durability, and ability to handle high pressure. They provide excellent resistance to corrosion and can effectively transport hydraulic fluids, making them a suitable choice for various hydraulic applications.

Q:Can steel pipes be bent?: Steel pipes can indeed be bent. To achieve this, one usually employs specific tools and methods like pipe bending machines or hydraulic presses. These tools exert pressure on the pipe, leading it to change shape and adopt the desired angle or form. The flexibility of steel pipes makes them adaptable and appropriate for an array of purposes, such as plumbing, construction, and manufacturing. Nonetheless, it's crucial to acknowledge that the extent to which a steel pipe can be bent relies on factors like its diameter, wall thickness, and the type of steel employed.

Q:How are steel pipes used in the construction of oil storage tanks?: Steel pipes are commonly used in the construction of oil storage tanks as they provide strength, durability, and corrosion resistance. These pipes are used to connect various components of the tank, such as the walls, roof, and bottom, ensuring a secure and leak-proof structure. Additionally, steel pipes are also used to transport oil within the tank and for the installation of necessary fittings, valves, and other equipment.

Q:Is the PVC tube a plastic tube or a plastic tube?.: Or polymer polymerized by radical polymerization under the action of light and heat. The vinyl chloride homopolymer and vinyl chloride copolymer are collectively referred to as vinyl chloride resins. The material is a non crystalline material. PVC materials often use stabilizers, lubricants, auxiliary processing agents, pigments, anti shock agents and other additives in practical use. Is not flammable, high strength, excellent resistance to climate variability and geometric stability. PVC has strong resistance to oxidizing agents, reducing agents and strong acids. However, it can be corroded by concentrated oxidizing acids such as concentrated sulfuric acid and concentrated nitric acid, and it is also not suitable for contact with aromatic hydrocarbons and chlorinated hydrocarbons.

Q:Can steel pipes be used for conveying hazardous materials?: Yes, steel pipes can be used for conveying hazardous materials. Steel pipes are known for their durability, strength, and resistance to corrosion, making them suitable for transporting various hazardous substances such as chemicals, gases, and liquids. Additionally, steel pipes can withstand high pressures and temperatures, ensuring the safe and efficient transportation of hazardous materials. However, it is important to ensure proper handling, maintenance, and adherence to safety regulations when using steel pipes for conveying hazardous materials.

Q:Can steel pipes be used for underground oil pipelines?: Indeed, underground oil pipelines can utilize steel pipes. The construction of underground oil pipelines heavily relies on steel pipes owing to their robustness, longevity, and resistance to corrosion. They possess the capability to endure the immense pressure and weight exerted by the oil being transported, along with external forces like soil displacement or seismic events. Moreover, steel pipes can be fortified with coatings or linings such as epoxy or polyethylene, enhancing their resistance to corrosion and extending their lifespan. In conclusion, steel pipes emerge as a dependable and extensively employed option for underground oil pipelines.

Q:What is the difference between steel pipes and PVC-O pipes?: The main difference between steel pipes and PVC-O pipes is the material they are made of. Steel pipes are made of metal, specifically steel, which gives them high strength and durability. On the other hand, PVC-O pipes are made of a type of plastic called polyvinyl chloride, which is reinforced with oriented molecules, making them extremely strong and resistant to both internal and external pressures. Additionally, steel pipes are prone to corrosion, while PVC-O pipes are resistant to rust and chemical degradation. PVC-O pipes are also lighter and easier to handle and install compared to steel pipes.
