Premium Drillpipefor Optimal Performance

DRILCO offers a full line of premium drillpipe available in a variety of sizes with API and non-standard wall thickness to deliver optimal torque, weight, and durability. Our manufacturing capability ranges from 27⁄8-in to 75⁄8-in diameter drill pipe in E, X, G, S or SS GRADES in both Range 2 and Range 3 lengths. Special sizes and proprietary grades are available on an individual order basis. Our technical representatives can help you select the best features to ensure maximum BHA performance.

Premium drillpipeFatigue in the transition area between the tool joint and the drillpipe is the most common cause of washouts and failures. Therefore, DRILCO uses specialized forging equipment, proprietary tooling, and manufacturing techniques to develop drillpipes with extended upset design and gradual taper, producing a uniform mechanical property throughout the material. The smooth transition between components results in a clean steel and enhanced hardenability. In addition, our proprietary tube chemistries are matched to our quench and temper heat treatment processes to achieve excellent impact values, high fatigue resistance, and extended product life.

Extended upset design maximizes drillpipe durability by reducing stress resistanceDrillstring durability is maximized by designing pipes that are resistant to fatigue, which is concentrated in areas with sudden changes in geometry. This is the upset area adjacent to the tool joint weld, which serves as the transition from the drillpipe’s cross-sectional part to the tool joint’s thick cross-sectional part. To increase stress resistance, the upset transition zone between the drillpipe’s body and the tool joint needs to be as smooth and gradual as possible.

DRILCO selects steel with stringent cleanliness requirements to ensure high fractured toughness that translates into higher safety margins. Using proprietary equipment for the upset areas, we can specify an extended internal upset with a shallow run-out angle that blends seamlessly into the drillpipe’s ID. These qualifications improve pipe performance and ensure its durability in this stress-prone region. To further reduce fatigue, we grind both the ID and OD of the assembled pipe adjacent to the weld line.

Tool joint forgings are required to meet or exceed API standards. Prior to assembly, each tool joint is inspected to guarantee dimensional properties and test to ensure they provide proper mechanical integrity. Our tool joints are usually supplied 2-in longer than standard API lengths to deliver additional re-cut capability and longer service life. Tool joints with longer lengths can also be supplied by special request.

Optional Features

■ Extended upset double shouldered premium connections ■ Premium hardbanding ■ Internal plastic coating ■ Factory make-up and break-out

Double-shouldered connections improve torque and hydraulic performanceDRILCO offers drillpipe with standard API threaded connections for all available sizes. In addition, we offer DRILCO DS compatible double-shouldered connections, which use a standard API thread form with a secondary internal shoulder. The connection allows you to increase ID or reduce OD, which significantly improves hydraulic and torque performance over conventional API connections. The DRILCO DS connections are compatible with standard API connection thread forms as well as other standard double shouldered connections.

Typical double-shouldered connections provide 30% to 40% greater torque capacity than standard API connections.

Hardbanding minimizes deterioration during drilling and casing rotationHardbanding material can be welded to the tool joint’s circumference to protect it from deterioration during drilling. Some hardbanding types also offer protection for the casing when rotating inside the casing. Whether the application is for standard tungsten carbide or casing friendly using our proprietary DRILCO DEFENDER series hardbanding products, we have the materials available to meet your most stringent requirements. Please be sure to specify your requirements when ordering or discuss your options with our DRILCO representatives.

Internal plastic coating prevents corrosion and maximizes durabilityThe internal plastic coating is applied to the inside of the drillpipe to prevent corrosion and extend pipe service life by reducing friction coefficient and improving flow rate and hydraulics. To provide you with high-quality coatings and fast turnaround on orders, we partner with coating service companies that have a proven reputation for timely deliveries based on scheduled workloads.

Make and break method minimizes galling and damage to drillpipe connectionsFactory make-up and break-out of tool joints is a proven method used to minimize galling and damage to new drillpipe connections. The process is performed in the manufacturing plant under controlled conditions to ensure consistency for optimal performance. If galling does occur during the process, the joint is repaired or replaced immediately, saving you rig time and logistical complications.
