Founded in 2013, Yantai Xinbaoshang Materials Technology Co., Ltd.
China's leading drill pipe manufacturer and supplier
Drill pipe is a core component in the oil and gas industry, serving as a key part of the drilling string. It is responsible for transmitting power from the drilling rig to the drill bit and conveying drilling fluid (mud) to the depths of the well, ensuring efficient and safe drilling operations. Drill pipe is manufactured using high-strength steel, offering exceptional wear resistance and corrosion resistance, enabling reliable performance under extreme geological conditions. Additionally, it offers excellent connectivity, with special threaded joints at both ends that seamlessly connect with other drilling pipes (such as heavy-duty drill pipes and drill collars) to form a complete drilling pipe string. This flexibility allows it to adapt to various drilling operation requirements, delivering outstanding performance whether in onshore or offshore drilling. Each drill pipe undergoes rigorous quality testing and meets API standards.
Torque Transmission:Drill pipes transfer the rotational force from the rig to the drill bit, enabling it to bore through rock formations.
Fluid Circulation:They act as a conduit for drilling fluid (mud) to flow downhole, cooling the bit, removing cuttings, and maintaining wellbore pressure.
Weight on Bit (WOB):Drill pipe contributes to the weight applied to the drill bit, which is essential for efficient penetration.
Casing and Tubing:Drill pipes are used in conjunction with casing and tubing to ensure the safe operation of the pipeline system.
Drill pipes are used to access underground steam and hot water sources for electricity generation and heating.
They are essential for reaching the high temperatures required for geothermal energy production.
Drill pipes are used to explore for mineral deposits by drilling boreholes into the earth.
They help in collecting core samples for analysis and determining the presence and extent of mineral resources.
Drill pipes, along with drill collars, are used to steer the drill bit along a planned path, enabling access to targets that are not directly below the rig.
In deepwater environments, drill pipes are crucial for reaching deep hydrocarbon reservoirs.
They are used to transport drilling equipment and materials to the seabed and back.
Construction:Drill pipes can be used in construction for drilling boreholes for foundations, anchoring, or other purposes.
Geotechnical Investigations:They are used in geotechnical studies to gather soil and rock samples for analysis.
Water Well Drilling:Drill pipes are used to create water wells for potable water or irrigation.
As a leading manufacturer and supplier of drill pipe products in China, our products cover most application scenarios in terms of size and standards. Our products strictly comply with international standards such as API and ASTM. If you have any other requirements for product specifications, please feel free to contact us for customization.
| Outside Diameter (OD) | API specifies various ODs, including common sizes like 2 3/8″, 2 7/8″, 3 1/2″, 4″, 4 1/2″, 5″, and 6 5/8″. |
| Wall Thickness | Varies with nominal size and weight, impacting the pipe’s ability to withstand pressure and bending. |
| Length | Drill pipes are typically available in lengths of 30 or 42 feet (Range 2) or 45 or 48 feet (Range 3). |
| Connections | API standards also define the thread types and dimensions for tool joints, which connect drill pipes to each other and other drilling equipment. |
| Material Grade | Drill pipe is available in different grades (e.g., E-75, X-95, G-105, S-135) with varying yield strengths to match different drilling depths and conditions. |
| API 5DP | This standard provides guidance on dimensions, material specifications, and manufacturing requirements for drill pipe. |
