The seamless carbon steel pipe for ships (gb5213-85) is the seamless carbon steel pipe for the manufacture of class I pressure pipe system, class II pressure pipe system, boiler and Superheater of ships. TMCP CCS E32 offshore steel plate. The working temperature of carbon steel seamless pipe wall shall not exceed 450 ℃, and that of alloy steel seamless pipe wall shall exceed 450 ℃.
Nowadays, transportation is an important factor in economic development. Our company's rapid development is also inseparable from a good geographical location. The company is located in Zhengzhou, an important TMCP CCS E32 offshore steel plate heavy industry area in Central China. Whether you are in Beijing, Shanghai or Guangzhou, you can visit our company very easily. My factory is nearby, convenient transportation and time saving.
Nickel element is mainly used to form and stabilize the austenite structure, so that the TMCP CCS E32 offshore steel plate steel has good mechanical properties, corrosion resistance and process performance. Molybdenum can quickly passivate stainless acid-resistant steel, and improve the corrosion resistance to solutions containing chloride ions and other non-oxidizing media. Titanium and niobium are usually used to fix the carbon in alloy steel and make it generate stable carbides to reduce the harmful effect of carbon on the corrosion resistance of alloy steel.
With the increase of temperature, the yield limit of TMCP CCS E32 offshore steel plate will decrease monotonically, but the tensile strength of TMCP CCS E32 offshore steel plate will rise to a high peak value at a certain temperature, and then decrease. This peak temperature is called the blue brittleness temperature of TMCP CCS E32 offshore steel plate. Near the blue brittleness temperature, the TMCP CCS E32 offshore steel plate strength increases and the plasticity decreases. The elongation and section shrinkage of TMCP CCS E32 offshore steel plate increase with the increase of temperature, but there is a low peak at the blue brittleness temperature. The blue brittleness temperature of low carbon steel ranges from 200 ℃ to 250 ℃. The blue brittleness of low alloy steel is not obvious as that of low carbon steel, and the blue brittleness temperature is higher.
Our company will accept the product quality objection registration record, pass it to the TMCP CCS E32 offshore steel plate production unit and relevant departments, and timely coordinate the supervision of product TMCP CCS E32 offshore steel plate quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
