Type: API 5DP Oil Drill Pipe
OD: 2 3/8”- 5”
Material Gread : E, X. G, S
Processing type: Forging
Thickened Form: EU IU IEU
Our company can provide various specifications of oil drill pipe, mainly in line with API 5DP drill pipe and in line with SY oil standard drill pipe. The drill pipe can be matched with the same grade of drill pipe joints according to customer requirements, and the manufactured drill pipe joints meet the APISPEC7-1 standard. The advanced oil drill pipe friction butt welding line can adjust the welding parameters to the best position to ensure the quality of the welding tape. Heat treatment process with internal and external cooling at the same time, mechanical properties are more uniform and stable. Equipped with automatic measuring and weighing, automatic spray mark record application, to ensure the traceability of products.
Advanced drill pipe thickening and heat treatment production line, using CNC tube body full length heating furnace, quenching machine, tempering furnace. Advanced heat treatment process and precise temperature control ensure the mechanical properties of the tube body, the hydraulic straightening machine of the tube body, to ensure the straightness of the tube body and the coaxial degree of the tube body.
It can produce oil drill pipe of different materials, lengths, diameters and wall thicknesses, and can also customize drill pipe according to customer requirements of materials, lengths, wall thicknesses and threads.
• Land exploration drilling: In the exploration stage of land oil and gas fields, the drill bit is connected to the surface drilling rig through oil drill pipe, and the drilling operation of vertical, directional or horizontal wells is carried out to find out the location, reserves and properties of underground oil and gas reservoirs.
• Offshore exploration drilling: In the development of offshore oil and gas fields, deep or shallow sea drilling operations are carried out through platforms or drillships equipped with drill pipes.
• Production Well Drilling: In an area of a proven oil and gas reservoir, a production well is drilled to establish a channel for oil and gas from formation to surface.
