Adaptors

All our crossover subs or adaptor subs are manufactured from certified heat-treated high tensile alloy steel, and we have a full set of accredited gauges that ensures that threads are machined to specification. All threads receive and anti-galling coating and are protected by heavy duty plastic thread protectors when they leave our premises.

Bottom crossover subs or adaptors can be given extra wear protection by the application of hard bonding welding. This will increase the life of this product, and be cost effective when drilling in abrasive formations.

Our factory is API approved and has an ISO quality system and all products are manufactured to exacting standards.

Drillrods

Drilling Project Services supplies quality drillrods engineered and manufactured to stringent specifications in diameters from 3 ½" (90mm) to 13 3/8" (340mm). All threads are machined using only accredited thread gauges from the highest grade certified alloy steel. Tube material specifications range from A106B to high grade alloy material and the factory operates a ISO9001 quality system. All threads are parkarised and always delivered with thread protectors to prevent thread damage.

The factory manufactures mining, waterwell and exploration drillrods, including reverse circulation drillrods.
