Whether seamless steel pipe or welded type, steel pipes marking is just like an identity card which gives others identity authentication. So, we cannot ignore the role of steel pipes marking.

 

Today, we can learn what kind of information should be listed in the pipelines marking before wholesale.

Manufacturer's name or mark, for example, Threeway would be our logo in our sold tubes.

Specification number.

Size, like NPS and weight class, schedule number and so on.

Grade.

Type of pipe.

Test pressure, seamless pipe and other types.

Nondestructive electric test and so on.

Heat number, lot number, run number.

Any additional information desired by the manufacturer or specified in the purchase order.
