Rotary Casings

HEMCO offers wide range of drill casing that are designed for rotary drilling without percussion.

Our casing joints are fabricated using high tensile strength steel especially heat treated for durability of the threads under repeated usage. The joints are machine welded onto seamless tubes that are lighweight while having adequate strength. We supply these casings for 102mm (4 in) to 152 mm (6 in) drilling.

Drill Rods

HEMCO API Drill Rods are designed for use in rotary drilling and rotary DTH applications. These are commonly used as single rotary rods or as the inner drill string on double head rotary-rotary or rotary-percussion applications.
The ends of the API rods are fabricated using high-tensile strength quenched and tempered steel. The rod ends are gas nitrided to provide additional life to the drill string. Rod ends are machine welded onto high strength seamless tubes.
API rods are manufactured in a variety of lengths and wall thicknesses and include internal flush designs for additional flushing capacity.
HEMCO can manufacture alternative rod lengths and spanner flats upon request.

• Long-life thread designs utilizing high strength steel
• Machine welding for a superior welded connection between threaded joints and mid-body
