Lifting subs is a special tool for lifting of the drill tools in petroleum, natural gas industry and geologic exploration.
Have better mechanical properties, grain size and metallurgical structure higher than API Spec 7-1 standard, according to a special heat treatment process the product’s hardness, strength, impact performance can be ensured. Wear layers mosaic cylindrical carbide has high-strength and durable resistance point.
Applications:
Lifting subs is a special tool for lifting of the drill tools in petroleum, natural gas industry and geologic exploration. It is a short drill pipe, used to trip up in drill collars when the collars of threads to hang card can be started drilling down. All threads are phosphated, copperized or cold worked.
Competitive Advantage:
Strict quality control
Competitive price
Just-in-time delivery
