The implementation standard for 37Mn gas cylinder steel pipe is GB18248.
GB18248 is a standard for gas cylinder pressure pipes. It stipulates the classification, code, size, shape, weight and allowable deviations, technical requirements, test methods, inspection rules, packaging, marking and quality certificates of seamless steel pipes for pressure pipes.
37Mn alloy gas cylinder steel pipe is one of them, used to manufacture gas cylinders.
Gnee's gas cylinder tubes have low levels of harmful elements and high purity of steel. The outer diameter size is controlled at +1%D, up to +0.5%D, and the wall thickness accuracy is controlled at +10%S, up to 5%S. Internal and external surface quality is good. Widely used in the manufacture of oxygen cylinders and hydrogen cylinder accumulators. 37Mn has good mechanical properties and process performance. Ordinary seamless gas cylinders can be produced by the first-pass normalizing process. Seamless gas cylinders with higher requirements can also be produced by the quenching and tempering process.
