Drill Pipe Specifications for Mining Industry

[Carloselealva]

Hi everybody, I am looking for information regarding Drill Pipe Specifications for Mining and Construction Industry. I have researched about the posible standards that could apply to this kind of product regarding the specific mining sector, but I have encountered that there is no further specifications than the API 5DP, DS-1 and NS-1 for Oil and Gas Industry, and even asked to some consultants if they know about specific standards related to Drill Pipes for mining, with no positive results. That´s why I ask to this community If you know or apply some specific standards for Drill Pipe in mining or only the same specs than oil industry?

Thanks in advance

About 40 years ago , I examined some some "Longyear" drill pipe. It was totally different from API drill pipe. It was non-upset integral joint , relatively thin wall. It was treated as expendable ,limited life material wherein occasional failures were expected. It could apparently not contain liquid pressure. I would not be surprised if there were no industry specifications. Maybe it is different today.
