Definitions
- the invention relates to the use of a spray-compacted copper-nickel-manganese alloy as a material for the production of Drillstring.
- the prior art components and Tools of copper materials in particular of Cu-Be alloys used, the combine these qualities in a special way.
- the copper-beryllium spacers, the austenitic, non-magnetizable Collars (so-called “drill collars”) are used.
- the invention is therefore based on the object to find a new use of the copper material, the required property profile also as far as possible fulfilled, but it Be-free.
- the object is inventively by the use of a spray compacting dissolved copper-nickel-manganese alloy, consisting of 10 to 25% nickel, 10 to 25% Manganese, the rest of copper and common impurities, consists (the percentage refers to the weight), as a material for manufacturing of drill string components.
- the primary molding process for the copper material is carried out by spray compacting (see. the so-called "OSPREY” process, for example, according to GB-A-1,379,261 / 1,599,392 or EP-A-0,225,732).
