Command Energy’s drill collars are made of modified AISI 4145H chromium molybdenum alloy steel. These drill collar bars are full-length heat treated and water quenched to obtain mechanical properties as specified by API Spec 7-1. Full mechanical and chemical mill test certifications are supplied with all drill collars. These mill test certifications guarantee a hardness range of 285 to 341 BHN and an impact value of 40 ft-lbs at room temperature, one inch below surface. All drill collar bars are trepanned then drifted to API specifications to ensure close tolerance bores. Drill collars are also supplied with the outer surface either machined or rough peeled.

Made of AISI4145H alloy steel, drill collar mainly used between the dill pipe and drill head and connected by conversion connector so that they can provide the pressure and weighting to dill head , in order to make the dill head to keep right trace . Api and iso standed
Drill collar is mainly used to provide bit weight to drill bit so that drill pipe is in tension. Especially drill collar can keep drill bit centralized and hole track by large rigidity. MS brand drill collar are manufactured strictly from API Spec7-1 and SY5411 standard.
1. Hardness range of 285 to 341 BHN and a charpy impact value of 40ft/lbs are guaranteed for evenly distributed 16 points in any cross sections at room temperature. 2. Connections as phosphate coated father machining to protect the threads from corrosive elements and to prevent galling upon initial make -up. Thread roots are cold rolled on API and H0-90 connections. 3. Pressed steel thread protectors are supplied to all drill collar that are equipped with standard connections. 4. Manufactured strictly according to API standard. 5. Widely used in oil, gas, HDD and geothermal field.
