Product Description
Junk sub is a special tool for catching the heavy iron fillings or grits which are too heavey to be completely circulated out of the hole. It is important for bottom-hole cleaning, ensuring the normal work of the bit and service lift.
Because of the different interspace to the wellbore between the cup O. and the rim of cup, the fluid speed dropped promptly and form a vortex,meanwhile, the carry ability of fludi also dropped. So the heavy objects in the fluid will fall into the cup and carried out in the trip process.
