A3: Within three days of placing an order, we will begin production. The specific shipping date is dependent upon international and government factors, but is typically 7 to 10 workdays.
Q4: What makes stainless steel stainless?
A4: Stainless steel must contain at least 10.5 % chromium. It is this element that reacts with the oxygen in the air to form a complex chrome-oxide surface layer that is invisible but strong enough to prevent further oxygen from "staining" (rusting) the surface. Higher levels of chromium and the addition of other alloying elements such as nickel and molybdenum enhance this surface layer and improve the corrosion resistance of the stainless material.
Q5: Can stainless steel rust?
A5: Stainless does not "rust" as you think of regular steel rusting with a red oxide on the surface that flakes off. If you see red rust it is probably due to some iron particles that have contaminated the surface of the stainless steel and it is these iron particles that are rusting. Look at the source of the rusting and see if you can remove it from the surface.
Q6: What is the difference between galvanized steel and galvalume steel?
A6: Galvanized steel is metallic coated with Zinc in various coating weights. Minimum recommended for painted metal roofs is G90. Galvalume is a zinc and aluminum coated steel that becomes an alloy and is recommended in either painted or bare applications with a minimum coating weight of AZ50. Galvalume has an excellent performance life in bare exposures. Hence if you are using a bare panel use galvalume and if painted use either.
Q7: Is there a difference in thermal conductivity between stainless steel and steel?
A6: Yes. Stainless Steel has a lower thermal conductivity rate than steel; approximately 1/3 to 1/5th depending on the material.
Q8: Is there a difference in electrical conductivity between stainless steel and steel?
A8: Yes. Steel is generally more conductive than stainless steel. Steel has resistivity in the range of 10~20Ωm, while stainless has a resistivity of approximately 60~72Ωm.

- Q: Are steel tubes and round steel in weight or length when purchased?
- The price must be measured by weight, and the length, volume and other specifications should be entered
- Q: What is the difference between steel pipe and fiberglass pipe?
- Steel pipe and fiberglass pipe differ in terms of material composition, durability, flexibility, and cost. Steel pipe is made of steel, which provides strength and resilience, making it ideal for high-pressure applications and underground installations. Fiberglass pipe, on the other hand, is composed of reinforced plastic fibers, resulting in a lightweight and corrosion-resistant material suitable for above-ground and corrosive environments. While steel pipe offers higher tensile strength, fiberglass pipe excels in its flexibility, allowing for easier installation and reduced maintenance. Additionally, steel pipe is typically more expensive due to the cost of materials and manufacturing processes, while fiberglass pipe is more cost-effective in terms of initial installation and long-term maintenance.
- Q: What are the different methods of inspecting steel pipes for defects?
- There are several methods of inspecting steel pipes for defects, including visual inspection, magnetic particle testing, ultrasonic testing, radiographic testing, and eddy current testing.
- Q: Can steel pipes be bent or curved?
- Yes, steel pipes can be bent or curved using specialized equipment and techniques such as pipe bending machines or hydraulic bending.
- Q: What is the difference between seamless and ERW steel pipes?
- Seamless steel pipes are made without any welded joints, resulting in a uniform and continuous structure. On the other hand, ERW (Electric Resistance Welded) steel pipes are created by welding the edges of the steel strip or coil together, forming a seam. This seam may be visible on the surface of the pipe. While seamless pipes are considered stronger and more reliable due to their uniform structure, ERW pipes are more cost-effective and commonly used for low to medium pressure applications.
- Q: How are steel pipes protected against seismic activities?
- Steel pipes can be protected against seismic activities through various measures such as using flexible joints, employing seismic bracing systems, and implementing proper installation techniques. Additionally, coating the pipes with corrosion-resistant materials and conducting regular inspections and maintenance can further enhance their protection against seismic events.
- Q: What are the different grades of steel used for pipes?
- Pipes are manufactured using various grades of steel, each possessing unique properties and applications. Some commonly utilized grades include: 1. Carbon Steel: This type of steel is widely employed in pipe manufacturing, particularly for low-pressure purposes. It contains a low carbon content, typically less than 0.30%, facilitating easy welding and forming. Carbon steel pipes are known for their durability and cost-effectiveness, making them suitable for diverse industries. 2. Stainless Steel: Stainless steel pipes are renowned for their corrosion resistance and high strength. They consist of an alloy of iron and chromium, with additional elements like nickel and molybdenum enhancing their properties. These pipes find extensive usage in industries such as chemical processing, food production, and oil and gas, where corrosion resistance is vital. 3. Alloy Steel: Alloy steel pipes are created by incorporating elements like manganese, chromium, or nickel into carbon steel. This enhances their strength, hardness, and wear resistance, rendering them appropriate for high-pressure and high-temperature applications. Industries such as power generation, petrochemical, and aerospace frequently employ alloy steel pipes. 4. Duplex Steel: Duplex steel represents a type of stainless steel that combines austenite and ferrite phases. This results in a material possessing exceptional strength, corrosion resistance, and toughness. Duplex steel pipes are commonly utilized in offshore oil and gas platforms, as well as in chemical and petrochemical industries. 5. Low-Temperature Steel: Low-temperature steel is specifically designed to withstand extremely cold temperatures without becoming brittle. These pipes find significant use in industries such as cryogenic storage, LNG transportation, and refrigeration. Choosing the appropriate grade of steel is crucial to ensure optimal pipe performance and longevity. Factors such as temperature, pressure, corrosion resistance, and cost should be taken into account when selecting the steel grade for pipes.
- Q: What is the difference between steel pipe and aluminum pipe?
- Steel pipes and aluminum pipes differ primarily in their composition and physical properties. Steel pipes are composed of iron and carbon, with added elements for strength and corrosion resistance. In contrast, aluminum pipes are made entirely of lightweight and highly corrosion-resistant aluminum. The weight of the pipes is a significant distinction. Steel is denser than aluminum, making steel pipes heavier and more robust. This characteristic makes steel pipes ideal for applications requiring structural strength and load-bearing capabilities. On the other hand, aluminum pipes offer advantages due to their lightweight nature. They weigh only about one-third of steel pipes, making them easier to handle, transport, and install. This lightweight property is especially beneficial in industries such as aerospace and automotive, where weight reduction is crucial. Corrosion resistance is another important consideration. Steel pipes are prone to rust and corrosion, especially in moist or corrosive environments. To address this issue, steel pipes are often coated or galvanized. In contrast, aluminum pipes naturally resist corrosion due to the formation of a protective layer of aluminum oxide on their surface. Cost is also a factor to consider. Generally, steel pipes are more cost-effective due to lower raw material and manufacturing costs. However, long-term maintenance costs and lifespan may vary between steel and aluminum pipes, so specific requirements and durability should be taken into account. In conclusion, the difference between steel and aluminum pipes lies in their weight, strength, corrosion resistance, and cost. Steel pipes are heavier, stronger, and more prone to rust and corrosion but are generally more cost-effective. Aluminum pipes are lightweight, corrosion-resistant, and costlier but offer advantages in weight reduction and specific applications requiring corrosion resistance. The choice between steel and aluminum pipes depends on the project's needs and desired properties for optimal performance.
- Q: Are steel pipes resistant to chemicals?
- Yes, steel pipes are generally resistant to chemicals. They have excellent corrosion resistance properties, making them suitable for transporting various chemicals in industries such as oil and gas, chemical processing, and wastewater treatment. However, the level of resistance can vary depending on the specific type of chemical and the grade of steel used. In some cases, additional protective coatings may be required to enhance chemical resistance.
- Q: Are steel pipes suitable for food processing facilities?
- Steel pipes are indeed appropriate for food processing facilities. They are extensively used in the food processing industry because of the multitude of advantages they offer. To begin with, steel pipes are highly durable and can withstand the high temperatures, pressures, and corrosive substances commonly used in food processing. This means that the pipes will not degrade or contaminate the food products. Moreover, steel pipes are easy to clean and maintain, which makes them perfect for upholding the high levels of hygiene required in food processing facilities. Furthermore, steel pipes possess excellent resistance to bacteria growth, thereby ensuring the safety and quality of the food being processed. Additionally, steel pipes are cost-effective and have a long lifespan, making them a dependable and economical choice for food processing facilities.
