Srict netallurgical test are performed pre specifications to ensure that the heat treatment produces consisitent and maxium hardness through the depth of the bar. Feartures and benefits: 1. hardness rannge 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 ar phosphate coated afther machinning 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 fo all drill collar that are equipped with standard connections
We supply slick drill collars, spiral drill collars and non-magnetic drill collars; their sizes are from 3-1/8 to 11 inches. Besides the drill collars in the table below, we can supply other drill collars at customers' request. Materials: Drill collars are manufactured from AISI 4145H modified steel, and are supplied in the "as rolled" surface finish condition. Alternative surface finishes are available. Trepanning and Heat Treatment: Drill collars are trepanned and drifted to API Spec 7-1. Full-length heat-treatment processes ensure that mechanical properties meet or exceed API Spec 7-1 requirements. A hardness range of 285-341, Brinell hardness and Charpy "V" notch minimum impact strength of 40 ft-lb at 70 F are guaranteed one inch below the surface. Traceability: Drill collar material and process traceability are maintained from receipt of the mill's certified raw material to completion of manufacturing. Serial numbers are die stamped on bar bodies. Rigid Inspection Procedures: We inspect all our drill collars to ensure compliance with API SPEC 7-1 standards. These inspections include visual dimensional checks as well as ultrasonic inspections over the entire body of the drill collar. Cold Rolling: Drill collar thread roots, as well as elevator recess upper radius, are cold-rolled. Cold rolling creates a compressive recess upper radius stress condition that increases fatigue life by minimizing crack initiation. Phosphate-coated or Copper Plating: All connections are phosphate-coated or copper plated to improve resistance to corrosion. Slip Groove, Elevator Groove and Size: Lake offers optional slip and elevator recesses to improve handling efficiency and safety. Unless otherwise specified, slip and elevator recesses are machined in compliance with API spec 7-1 guidelines. Thread Protectors: Our company offers steel, cast steel and plastic steel thread protectors for its drill stem products.

Drilling barite, also known as barite or baryte, is a mineral composed of barium sulfate (BaSo4). it is a critical component used in drilling industry, particularly for oil and gas exploration. In the intricate tapestry of modern oil and gas exploration, the significance of a seemingly mundane mineral like barite (BaSO4) cannot be overstated. This dense mineral, primarily composed of barium sulfate, plays a critical role in the drilling process, proving to be an indispensable asset in the quest for energy resources beneath the Earth's surface. Drilling barite's unique properties, including its chemical formula BaSO4 and substantial weight, are what make it an irreplaceable component in drilling operations. This exploration delves deep into the world of drilling barite, uncovering the layers of its importance, utility, and environmental considerations in oil and gas exploration. Chemical Composition and Weight: The Core of Drilling Barite's Efficacy At the molecular level, drilling barite is fascinating. Its chemical formula, BaSO4, reveals its composition - barium sulfate, a compound that naturally possesses a high specific gravity, typically ranging between 4.2 to 4.5 g/cm. This significant density, much higher than that of most minerals, is what lends barite its invaluable weighting property, essential for drilling fluids used in oil and gas exploration. The drilling industry demands materials that can ensure the stability and pressure of the wellbore, and barite's heavyweight nature answers this call perfectly. The high density helps in counterbalancing the immense pressures encountered during drilling, preventing the well from collapsing and offering a robust barrier against high-pressure reservoirs that could otherwise lead to blowouts. Operational Significance: Beyond Weighting Drilling Fluids While its primary role as a weighting agent in drilling fluids is well known, barite's contribution to the drilling process extends beyond just this function. Its inertness chemical stability under various conditions makes it an ideal additive, not reacting adversely with other components of the drilling mud or the geological formations encountered. This stability is crucial in maintaining the integrity of the drilling fluids over time, ensuring consistent performance throughout the drilling operation. Furthermore, barite contributes to the lubrication and cooling of the drill bit, protecting it from the extreme conditions it faces as it penetrates the earth. The fine particles of barite also assist in the efficient removal of cuttings from the drill site, facilitating a cleaner drilling process and minimizing the risk of blockages that could halt operations
