Q:What are the common protective coatings used on the inner surface of steel pipes?: The common protective coatings used on the inner surface of steel pipes include epoxy, polyurethane, and cement mortar coatings. These coatings provide corrosion resistance, prevent the formation of scales, and improve the durability and lifespan of the pipes.

Q:What's the difference between hot dip galvanizing and cold galvanizing? Which kind of galvanizing method is good?: Cold galvanizing refers to the zinc plating, the coating is thinner, corrosion resistance is slightly worse, variable color. Environmental pollution.Hot dip galvanized by molten zinc ingots, the coating thickness can be adjusted, good corrosion resistance, and subsequent passivation, can be used for outdoor rust, long service life, some up to 20 years.

Q:Can steel pipes be used for conveying sewage sludge?: Yes, steel pipes can be used for conveying sewage sludge. Steel pipes are commonly used in various industrial applications, including the transportation of sewage sludge. They are strong, durable, and resistant to corrosion, making them suitable for handling the potentially corrosive nature of sewage sludge.

Q:How are steel pipes coated for aesthetic purposes?: Steel pipes can be coated for aesthetic purposes through various methods such as painting, powder coating, or using decorative finishes like chrome plating. These coatings not only enhance the appearance of the steel pipes but also provide protection against corrosion and increase their durability.

Q:How are steel pipes used in the manufacturing of food processing equipment?: Steel pipes are commonly used in the manufacturing of food processing equipment due to their durability, corrosion resistance, and ability to handle high temperatures. They are used to transport liquids, gases, and food products within the equipment, ensuring hygienic and efficient operation. Additionally, steel pipes can be easily cleaned and sanitized, making them ideal for maintaining food safety standards in the manufacturing process.

Q:Are steel pipes suitable for nuclear power plants?: Yes, steel pipes are suitable for nuclear power plants. Steel pipes are commonly used in nuclear power plants due to their high strength, durability, and resistance to high temperatures and pressures. They are used for various applications such as transporting coolant, steam, and other fluids within the plant. Additionally, steel pipes can be fabricated to meet specific requirements and withstand the harsh operating conditions of nuclear power plants, making them a reliable and suitable choice for this industry.

Q:The plastic pipe and steel pipe difference: The steel plastic pipe is a general term, which includes plastic pipe, plastic lined pipe. Plastic pipe external coating, zinc coated and so on in Shanghai, Fujian, Portland, professional in this area

Q:Can steel pipes be used for underground water supply networks?: Yes, steel pipes can be used for underground water supply networks. Steel pipes are durable, resistant to corrosion, and have high strength, making them suitable for carrying water underground. Additionally, steel pipes can withstand high pressure and temperature variations, ensuring a reliable and long-lasting water supply system.

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:What are the common methods for cleaning the inner surface of steel pipes?: Some common methods for cleaning the inner surface of steel pipes include chemical cleaning, mechanical cleaning, and high-pressure water jetting. Chemical cleaning involves using solvents or acids to dissolve and remove any contaminants or residue. Mechanical cleaning involves using tools such as wire brushes, scrapers, or pigs to physically scrub and scrape the inner surface of the pipes. High-pressure water jetting involves using a pressurized stream of water to blast away dirt, scale, or other deposits.
