Water Well Drill Pipes/Water Well Drill Rods/DTH Drill Pipes


  • প্রযুক্তিগত বৈশিষ্ট্য
  • কারিগরী পরামিতি

Main Technical Features

● Traditionally the threads and the joint between the tube and the end-pieces are vulnerable. To

combat the problem we've friction-welded the joints for maximum strength and heat-treated

the end-pieces for optimum durability.

● Drill pipe is generally described by tube OD, nominal weight, pipe grade, type tool joint,

thread connection and classification.

● We do special heat-treating the threads ensures not only a long service life, but also simplifies

joining and breaking.

● Standard material for drill pipe is R780,but other material S135,G105 are available.
