pipe used in bridge construction project

20MnG steel pipe is a type of steel pipe commonly used in high temperature and high pressure applications, commonly used in boilers, heat exchangers and other high temperature and high pressure equipment.

A709-50W is American standard weathering steel produced according to ASME standards, with a thickness between 3mm and 100mm. It is often used in steel structures or large buildings such as highways and bridges that are exposed to harsh climate environments for a long time.

A209 alloy pipe is an American standard alloy steel pipe. It not only has high oxidation resistance and high temperature steam corrosion resistance, but also has good impact toughness, high and stable long-lasting plasticity and thermal strength properties.

Both SA210C and A210GradeC seamless steel pipes comply with ASTM A210/A210M and ASME SA210/SA210M standards and are used in boilers and superheaters.
