DIN 1629 GRADE ST37-0 HOT ROLLED NON-ALLOY SEAMLESS STEEL TUBES
OVERVIEW
Carbon steel seamless steel pipe is kind of long steel. Steel pipe has hollow section, which is widely used as pipeline for conveying fluids, such as oil, natural gas, gas, water and some solid materials. Compared with solid steel such as round steel, steel pipe is lighter in weight under the same bending and torsional strength. It is an economic section steel. It is widely used in manufacturing structural and mechanical parts, such as oil drill pipe, automobile transmission shaft, bicycle frame and steel scaffolding used in construction.
DIN 1629 Seamless Steel pipe Of Non Alloys Steels are made of unalloyed steels, it’s main grades are St 37.0, St44.0, St52.0, Din 1629 seamless steel pipes application fields are: chemical plant, vessels, pipework construction and for common mechanical engineering purposes. Normally DIN 1629 standard are manufactured with no limiting working pressure values. Working temperature is limited below 300℃.
