It is available with an external diameter of 219 to 3620mm and a wall thickness of 4 to 31mm. This product is in full compliance with standards such as API 5L, GB/T9711.1, GB/T9711.2, and SY/T5037-2000. As a common structuring component of piers, roads, and bridges, our pipe has a broad range of applications in fields such as sewerage, transportation, water supply, coal gas, petroleum gas, and civil engineering. It is an excellent medium for the safe conveying of liquids or gases.
