37Mn 34Mn2V Seamless Gas Cylinder Pipe
gnee pipe team
34Mn2V gas cylinder steel pipe is a high-quality carbon steel and alloy steel seamless pipe. It is mainly used for chemical equipment and pipelines with working temperatures of -40-400 degrees Celsius and working pressures of 10-32 MPa. Suitable for transporting synthetic ammonia, urea, methanol and other media.
34Mn2V Seamless gas cylinder tubes are typically designed to withstand the high pressure conditions associated with gas storage. These pipes are critical components of the cylinders used to store and transport gases such as compressed natural gas (CNG) or other industrial gases.
37Mn gas cylinder tube has good mechanical properties and process performance. Ordinary normalizing process can be used to produce ordinary seamless gas cylinders, and quenching and tempering process can also be used to produce seamless gas bottles with higher requirements.
Seamless 37Mn gas cylinder tubes have low content of harmful elements and high purity of steel. The outer diameter is controlled at ±1%D, up to ±0.5%D, and the wall thickness accuracy is controlled at ±10%S, up to ±5 %S, with good internal and external surface quality, widely used in the manufacture of oxygen bottles, hydrogen bottles, and accumulators.
