FAQ

Stainless steel pipes and galvanized steel pipes are both commonly used in various industries and applications, but they have distinct differences in terms of their composition, properties, and performance. One of the primary differences between stainless steel and galvanized steel pipes is their composition. Stainless steel pipes are made from an alloy of iron with a minimum of 10.5% chromium content, which provides excellent corrosion resistance and durability. On the other hand, galvanized steel pipes are steel pipes that have been coated with a layer of zinc to protect them from corrosion. In terms of corrosion resistance, stainless steel pipes outperform galvanized steel pipes. The chromium content in stainless steel forms a passive layer of chromium oxide on the surface, which acts as a barrier against corrosion and rust. This makes stainless steel pipes highly resistant to pitting, crevice corrosion, and general corrosion caused by various substances and environmental factors. Galvanized steel pipes, although coated with zinc, are more susceptible to corrosion over time, especially when exposed to harsh conditions or corrosive substances. Another key difference lies in their durability and lifespan. Stainless steel pipes are known for their exceptional strength, toughness, and longevity. They can withstand high pressures, extreme temperatures, and mechanical stresses, making them suitable for demanding applications. Galvanized steel pipes, while durable, have a relatively shorter lifespan compared to stainless steel due to the eventual degradation of the zinc coating, which exposes the underlying steel to corrosion. In terms of maintenance, stainless steel pipes require minimal upkeep due to their inherent corrosion resistance. They are easy to clean and do not require regular painting or coating. On the other hand, galvanized steel pipes may require periodic inspection, maintenance, and re-coating to ensure prolonged protection against corrosion. Cost-wise, galvanized steel pipes are generally more economical upfront compared to stainless steel pipes. However, when considering the long-term benefits of stainless steel's corrosion resistance and durability, the overall cost-effectiveness of stainless steel pipes often surpasses that of galvanized steel pipes. In conclusion, stainless steel pipes offer superior corrosion resistance, durability, and longevity compared to galvanized steel pipes. While galvanized steel pipes may be more cost-effective upfront, stainless steel pipes provide long-term benefits and performance advantages, making them a preferred choice in many applications where corrosion resistance and durability are critical considerations.

Yes, stainless steel pipes can be used for underground sewage systems. Stainless steel is a highly durable and corrosion-resistant material, making it suitable for use in underground applications where exposure to moisture and chemicals is common. It can withstand the harsh conditions of sewage systems, including the corrosive nature of wastewater and the pressure from the soil. Additionally, stainless steel pipes have a long lifespan, reducing the need for frequent replacements and maintenance. However, it is important to consider the specific requirements and regulations of the local sewage system and consult with professionals to ensure proper installation and compatibility with other system components.

The tensile strength of stainless steel pipes can vary depending on the specific grade and composition of the steel. However, stainless steel is known for its high tensile strength, making it a popular choice for various applications that require strong and durable pipes. On average, stainless steel pipes have a tensile strength ranging from 500 to 1500 megapascals (MPa). This high tensile strength allows stainless steel pipes to withstand significant pressure and stress, making them suitable for use in industries such as construction, oil and gas, chemical processing, and automotive manufacturing. It is important to note that the exact tensile strength of stainless steel pipes can be influenced by factors such as the manufacturing process, heat treatment, and any additional alloying elements present in the steel. Therefore, it is essential to consult the specific technical specifications or standards for the particular grade of stainless steel pipes in order to determine their exact tensile strength.

Stainless steel tube, also known as why tube?

Use can be divided into oil well pipe (casing, tubing and drill pipe etc.), line pipe, boiler tube, mechanical structure, hydraulic prop pipe pipe, cylinder pipe, geological pipe, chemical pipe (high pressure fertilizer pipe, oil cracking tube) and shipbuilding pipe etc.

Yes, stainless steel pipes can be used for oil refinery applications. Stainless steel is known for its excellent corrosion resistance properties, making it suitable for handling various corrosive substances commonly found in oil refineries. Additionally, stainless steel pipes are durable and can withstand high temperatures and pressures, making them a reliable choice for oil refinery operations.

Yes, stainless steel pipes are suitable for fertilizer production. Stainless steel pipes offer a number of advantages that make them a preferred choice for use in the fertilizer industry. Firstly, stainless steel pipes are highly resistant to corrosion, which is particularly important in the production of fertilizers. Fertilizer production involves the use of chemicals and substances that can be highly corrosive, such as ammonia, sulfuric acid, and phosphoric acid. Stainless steel pipes can withstand the corrosive effects of these substances, ensuring the integrity and longevity of the piping system. Additionally, stainless steel pipes have excellent strength and durability, making them able to withstand the high pressures and temperatures often encountered in fertilizer production processes. This ensures the safe and efficient transportation of the fertilizer materials within the production plant. Furthermore, stainless steel pipes are hygienic and easy to clean, which is crucial for maintaining the purity of the fertilizer products. Stainless steel has a smooth surface that resists the buildup of bacteria, dirt, and other contaminants, ensuring that the pipes do not contaminate the fertilizer during production. Lastly, stainless steel is a sustainable and environmentally friendly material. It is 100% recyclable, making it a more sustainable choice compared to other pipe materials. Additionally, stainless steel has a long lifespan, reducing the need for frequent replacements and minimizing waste. In conclusion, stainless steel pipes are highly suitable for fertilizer production due to their corrosion resistance, strength, durability, hygienic properties, and environmental benefits.
