Product Description

Product Description

Heavy Weight Drill Pipe 
 

Integral Heavy Weight Drill Pipes

Heavy Weight Drill Pipes are machined from 31ft bars of AISI 4145H Mod. alloy steel,full-length quenched and tempered to obtain the API Spec. 7-1, NS-1 and Ds-1 mechanical properties.All Heavy Weight Drill pipe bars are trepanned and inside diameters are gauged to APISpec.7-1 specification with a 10 ft drifts mandrel
 

Welded Heavy Weight Drill Pipes

Welded Heavy Weight Drill Pipes consists of two tool joints and one central tube, assembled by welding.Tool joints are made from AlS1 4145H Mod. alloy steel, quenched and tempered to obtain the AP1 Spec.7-1.NS-1 and Ds-1 mechanical properties. Central tube is made from 1340 normalized steel to achieve APISpec.7-1 NS-1 and DS-1 mechanical properties.Each weld zone is fully ultrasonic inspected and hardness tested.
 

Spiral Heavy Weight Drill Pipes

Heavy Weight Drill Pipes are machined from 31ft bars of AISI 4145H Mod. Alloy steel full-length quenched and tempered to obtain the API Spec.7-1, NS-1 and Ds-1 mechanical properties.
 

QUALITY CONTROL

When delivered each HWDP has been inspected according to APISpec.7-1, NS-1 and Ds-1.
An inspection certificate is provided including mechanical properties, chemical analysis and inspections.
Each weld zone is fully ultrasonic inspected and hardness tested.
 

CONNECTIONS

APl relieve groove pin and bore back box stress relief features are standard.Thread roots are cold-worked to improve fatigue resistance of the connection. All connections are phosphatized and coated with AP1thread compound to prevent corrosion and galling. Standard pressed steel protectors are installed to ensure adequate thread protection. On request, High Torque connections can be manufactured.Heavy Weight Drill Pipes can also be delivered blank ended.
 

HARDBANDING

To optimize wear resistance, Hardbanding is standard on tool joints and central upset
Standard wear bands:
One 4" wear pad on pin and box, plus 1" pad on box taper section (optional 
Two 3" wear pads on central upsets (optional for Spiral HWDP).
Standard hardbanding is raised (1/8" oversize).
Flush application available on request (optional)
Type of hardbanding is according to customer's requirements.
We offer the main following hardbanding types:
Fine grain size tungsten carbide particles
Duraband NC (Postle Industries)
Tuffband NC (Postle Industries)
Arnco 100XT
Arnco 300XT
Other hardbanding types can be provided, on request.
 

INTERNAL COATING

Internal coating can be provided on request.
* Note: NS-1 and DS-1 properties and certification are provided on request.Please specify your needs in your enquiry.
