1Structure of Seamless Pipe: 

We are company that have many years experience and professional manager team and engineer team and sales team, sure we will provide you high quality of pipe and professioanl service.

Seamless pipe possesses a hollow section and without seam around the strip steel. It is made with solid bar or steel ingot by perforating machine. As the facture process does not include any welding, seamless pipes are considered to be stronger and more durable. Generally speaking, seamless pipe has better pressure resistance and security than other classifications, and was usually more easily available than welded pipe.

Q:Can stainless steel pipes be used for food processing?
Indeed, stainless steel pipes are suitable for food processing purposes. The food industry favors stainless steel due to its remarkable resistance to corrosion, remarkable strength, and hygienic features. Its non-reactive nature ensures that it does not interact with food or introduce any flavor or scent. Stainless steel pipes are effortless to clean, sanitize, and upkeep, rendering them appropriate for employment in food processing scenarios where cleanliness and hygiene hold paramount importance. Furthermore, stainless steel pipes exhibit the capability to endure elevated temperatures and pressures, thus making them an ideal choice for a diverse range of food processing activities, including the transportation, storage, and distribution of food products.
Q:304 stainless steel will rust it?
Why is stainless steel rust? When the stainless steel tube surface appear brown rust (point) when people are surprised: "the stainless steel does not rust, rust is stainless steel, steel may be a problem". In fact, this is a lack of understanding of stainless steel one-sided misconceptions. Stainless steel will rust under certain conditions.
Q:What is the difference between seamless and hot-finished stainless steel pipes?
Seamless stainless steel pipes are manufactured without any welding seams, resulting in a smooth and uniform appearance. They are made by piercing a solid billet of stainless steel and then extruding it into a hollow tube shape. On the other hand, hot-finished stainless steel pipes are made by heating a solid billet and then rolling it into a tube shape while hot. This process may result in visible welding seams, but the pipes are still durable and suitable for various applications.
Q:What are the different standards and specifications for stainless steel pipes?
There are several different standards and specifications for stainless steel pipes, depending on their intended use and the industry they are being used in. Some common standards include ASTM A312/A312M, which covers seamless, welded, and heavily cold worked austenitic stainless steel pipes; ASTM A358/A358M, which specifies electric-fusion-welded austenitic chromium-nickel stainless steel pipes; and ASTM A790/A790M, which covers seamless and welded ferritic/austenitic stainless steel pipes. Additionally, there are standards specific to different countries, such as EN 10216-5 in Europe and JIS G3459 in Japan. These standards outline the requirements for dimensions, material composition, mechanical properties, and other characteristics of stainless steel pipes.
Q:What is stainless steel pipe?
Stainless steel pipe is a type of pipe made from an alloy of steel and chromium, with a high resistance to corrosion and staining. It is commonly used in various industries, including construction, automotive, and manufacturing, due to its durability and ability to withstand harsh environments.
Q:Are stainless steel pipes suitable for food storage facilities?
Yes, stainless steel pipes are highly suitable for food storage facilities. Stainless steel is a popular choice in the food industry due to its numerous beneficial properties. Firstly, stainless steel is highly resistant to corrosion, which is essential in food storage facilities where contact with moisture and various food products is common. This resistance ensures that the pipes will not rust or degrade over time, preventing any potential contamination of the stored food. Furthermore, stainless steel pipes are easy to clean and maintain, making them ideal for food storage facilities where strict hygiene standards must be met. The smooth and non-porous surface of stainless steel pipes prevents the accumulation of bacteria, ensuring the stored food remains safe and uncontaminated. Stainless steel is also a non-reactive material, meaning it does not leach any harmful substances into the food. This is particularly important for food storage facilities as it ensures the integrity and quality of the stored food products are maintained. Additionally, stainless steel pipes have excellent strength and durability, allowing them to withstand the high pressures and temperature variations commonly encountered in food storage facilities. This ensures the pipes will not fail or break, providing a reliable and long-lasting solution. In conclusion, stainless steel pipes are highly suitable for food storage facilities due to their corrosion resistance, ease of cleaning, non-reactive nature, and strength. They provide a safe and hygienic environment for storing food, ensuring the integrity and quality of the stored products.
Q:Stainless steel pipe chamfering how to process?
Chamfering machine is a kind of small precision machine tool which is specialized in mould manufacture, hardware machinery, machine tool manufacturing, hydraulic parts, valve manufacturing, textile machinery chamfering and milling, planing and other processing methods.
Q:Stainless steel welded pipe or seamless pipe expensive?
Stainless steel is generally divided into three categories: martensitic stainless steel, ferritic stainless steel, austenitic stainless steel, duplex stainless steel and precipitation hardening stainless steel. The price is roughly the same order as stainless steel. But each category has a cheaper and more expensive one, and the difference can be great.
Q:How is stainless steel pipe different from carbon steel pipe?
Stainless steel pipe and carbon steel pipe differ mainly in their composition and corrosion resistance properties. Stainless steel pipe contains a higher percentage of chromium, which forms a passive oxide layer on its surface, making it highly resistant to corrosion and oxidation. On the other hand, carbon steel pipe does not have this protective layer, making it more prone to rust and corrosion. Additionally, stainless steel pipe is generally more expensive than carbon steel pipe due to its superior corrosion resistance and durability.
Q:What is the difference between 904L and 316L stainless steel pipes?
The main difference between 904L and 316L stainless steel pipes lies in their composition and properties. 904L stainless steel is a high alloy austenitic stainless steel with higher levels of chromium, nickel, and molybdenum, making it highly resistant to corrosion in various environments, including harsh industrial and marine conditions. On the other hand, 316L stainless steel is a lower alloy austenitic stainless steel that contains less chromium, nickel, and molybdenum, making it less resistant to corrosion compared to 904L. Therefore, 904L stainless steel pipes are typically preferred in applications that require exceptional corrosion resistance, while 316L stainless steel pipes are suitable for general-purpose applications.
