Product Detail
The project was completed in 2020. The designed wall thickness (25.4mm) of the project reached the maximum wall thickness of the spiral steel pipe, and the steel grade was relatively high, reaching API 5L X65 PSL1 grade. The steel pipe also required C9 lock welding. The welding process, welder assessment and flaw detection inspection standards all met the corresponding Australian standards: AS/NZS 1554.1, AS 2980, AS 2207, AS 1171, and the whole process was supervised by the customer.
