Shanghai Songjiang Vibration Absorber Group Co., Ltd. official website introduces DN125 stainless steel hose information. Songjiang Group produces various models of stainless steel hose, mainly used in pipeline systems, providing flexible connections to protect pipelines and prevent ruptures and leaks when there is thermal expansion and contraction causing pipes to collide.
Product Name: DN125 stainless steel hose
Model: JTW
Caliber: DN125
Pressure: 16KG
Flange material: carbon steel forging
Corrugated material: stainless steel 304
Woven net material: stainless steel 304

DN125 Stainless Steel Hose Material Description:
Corrugated Tube Body, Braided Mesh: To ensure a longer service life, all made from stainless steel 304, supporting various spectrometer tests, with a tenfold compensation for any falsification, and thickness exceeding industry standards.
Flange Connection: All flanges are made of authentic forged materials from Shanxi, providing excellent strength and sealing properties. Avoid comparing them with commonly seen cast steel or steel plate flanges on the market; there is no comparability.
Welding Material: The welding material exceeds the grade standards of the base material, ensuring a more robust welding point.
Introduction to Stainless Steel:
Stainless steel, as defined by GB/T20878-2007, is a type of steel with stainless and corrosion-resistant properties as its main characteristics, with a chromium content of at least 10.5% and a carbon content not exceeding 1.2%.
Stainless steel is commonly referred to as corrosion-resistant steel. Steel that is resistant to weak corrosive media such as air, steam, and water, or steel that has stainless properties, is called stainless steel. Steel that resists corrosion by chemical corrosive media (acids, alkalis, salts, etc.) is called acid-resistant steel.
Due to the differences in their chemical compositions, their corrosion resistance varies. Ordinary stainless steel generally does not resist corrosion by chemical media, while acid-resistant steel generally has stainless properties.
The term “stainless steel” does not solely refer to a single type of stainless steel; it represents over a hundred industrial stainless steels. Each developed stainless steel has good performance in its specific application field. The key to success is to first clarify the purpose and then determine the correct steel grade. In the field related to construction applications, there are usually only six types of steel. They all contain 17-22% chromium, and better grades also contain nickel. The addition of molybdenum can further improve atmospheric corrosion resistance, especially resistance to corrosion in chloride-containing atmospheres.
In general, the hardness of stainless steel is higher than that of aluminum alloy, and the cost of stainless steel is higher than that of aluminum alloy.
Stainless steel is commonly classified by its structural state: martensitic steel, ferritic steel, austenitic steel, duplex (ferrite-austenite) stainless steel, and precipitation-hardening stainless steel, among others. Additionally, it can be classified by composition: chromium stainless steel, chromium-nickel stainless steel, and chromium-manganese-nitrogen stainless steel, etc. There are also special stainless steels for pressure vessels (GB24511_2009_Pressure Equipment Stainless Steel Plate and Steel Strip).
Ferritic Stainless Steel: Contains 15%-30% chromium. Its corrosion resistance, toughness, and weldability improve with an increase in chromium content. Its resistance to chloride stress corrosion is better than other types of stainless steel. Examples include Cr17, Cr17Mo2Ti, Cr25, Cr25Mo3Ti, Cr28, etc. Ferritic stainless steel has good corrosion resistance and oxidation resistance due to its high chromium content. However, its mechanical and process properties are relatively poor. It is mostly used in low-stress acid-resistant structures and as anti-oxidation steel. This type of steel can resist corrosion from the atmosphere, nitric acid, and saltwater solutions. It also has good high-temperature oxidation resistance and a small coefficient of thermal expansion, making it suitable for equipment in nitric acid and food factories. It can also be used to make parts that work at high temperatures, such as gas turbine parts.
