Product Description

The oil drill pipe serves as the primary conduit for transmitting drilling fluid and rotational torque from the surface to the drill bit.

Manufactured in compliance with API 5DP and NS-1 standards, it offers multiple steel grades to meet varying well depths and torque requirements.

The pipe features end-thickened designs (IU, EU, IEU) to enhance connection strength; its joints are precision-machined from high-strength alloy steel and incorporate flow channels to ensure efficient fluid circulation.

Longway manufactures API 5DP oil drill pipe for onshore and offshore oil and gas drilling projects.

Multiple pipe-body sizes, nominal weights, wall thicknesses, upset types, steel grades and rotary-shouldered connections are available.

Each configuration can be selected according to the well profile, drilling depth, torque, tensile load, drilling fluid and service environment.

Longway API 5DP oil drill pipe provides:

♦ E75, X95, G105 and S135 steel grade options

♦ IU, EU and IEU upset configurations

♦ NC and FH connection options shown in the specification table

♦ Precision-machined pin and box tool joints

♦ Friction-welded tool joints with controlled weld-zone processing

♦ Optional hardbanding for abrasive and high-contact drilling conditions

♦ Optional internal coating for corrosion and fluid-flow requirements

♦ Material Test Certificates and inspection documentation

♦ 100% non-destructive testing for product quality verification
