A drill collar is made of structure steel alloy forged or rolled from AISI 4145H. The drill collar is processed and made as per Standard API SPEC 7. Thermal treatment is conducted over the whole length of the products to ensure that its mechanic performance can meet the provisions under the Standard API SPEC 7. Its Brinell hardness ranges between 285 and 341. And impact energy of its Charpy V-shaped notch can be 40 ft-lb at a temperature of 1 inch below the surface of the pipe.
Our company may, as per users'requirements, process slips and elevator grooves on drill collars. Hoisting joints and safety grips are not required for the grooves to ensure safety during operations.
