Excessive impurity content in stainless steel seamless elbow materials will cause multiple performance degradation and safety hazards. 1. Risk of mechanical performance collapse Strength and toughness attenuation: Sudden drop in blast resistance pressure: Impurities such as sulfur and phosphorus cause grain boundary embrittlement, resulting in a drop of over 18% in blast pressure for DN100 elbows under 10MPa conditions. Low [...]

The measures to extend the service life of stainless steel seamless elbows need to be combined with the optimization of the entire process of corrosion prevention, installation, and maintenance! 1. Strengthen surface protection Coating treatment: Spray anti-corrosion coating or electroplating protective film to block medium erosion (such as chemical pipelines coming into contact with acidic and alkaline media). Hot dip [...]

What should I do if there are leakage holes on the surface of stainless steel seamless elbows? How should we handle it again? The occurrence of leakage holes on the surface of stainless steel seamless elbows is generally related to the following factors: 1. Material impurities and pores Impurities such as sulfur and phosphorus in raw materials exceed the standard [...]

The storage temperature of stainless steel seamless elbows should be strictly controlled within the range of minus 5 ℃ to room temperature to prevent damage to material properties. Its temperature control requirements: Low temperature lower limit: ≥ -5 ℃ (below this temperature may lead to the risk of brittle cracking or frost cracking) High temperature upper limit: ≤ room temperature [...]

The wear reasons of stainless steel seamless elbows can be divided into four categories: mechanical wear, corrosion wear, processing defects, and environmental factors. 1. Mechanical wear and tear Material erosion and wear: When the medium (such as fluids containing coal ash and sediment) flows through the elbow, it is subjected to centrifugal force, and particles repeatedly collide with the outer [...]

Although stainless steel seamless pipes have corrosion resistance, they cannot withstand any corrosion! What corrosive media can stainless steel seamless pipes withstand? 1. Chloride ion erosion Chloride ions (such as salt water and sweat) can damage the passivation film on the surface of seamless pipes, causing pitting corrosion or stress corrosion cracking, especially for 304 steel pipes, which pose a [...]
