Seamless Steel Drill Pipe for Drilling Operations
Drill pipe includes pipe body and tool joints(box and pin) welded together, used to connect drilling rig surface equipment and bottom equipment or bottom hole equipment. Drill pipe can bear heavy internal and external pressure, and twist, bend and vibration which can be used more than one time during oil or gas production.
Description
A drill pipe is a seamless steel pipe that composes around 95% of the length of a drill string. For clarity, a drill string is what is used to actually drill into the ground to extract resources. The drill pipe is hollow, which allows drilling fluid to flow freely throughout the pipe and the pumping process to be completed successfully.
Drill pipes are steel tubulars fitted with threaded ends called tool joints, which are commonly used in tension in the top part of the drill string to pump fluid and transmit torque to the bit.

Uses of packaging in the steel industry
Protective function
- Prevent steel products from physical damage, such as collision, scratching and extrusion, during transport, storage and handling to avoid affecting the quality and appearance of the products.
- Insulate from external environmental factors, such as humid air, rain, dust, etc., to reduce the risk of rust and corrosion of steel and ensure the performance and service life of the products.
Wooden box packaging
- Use: Mainly used to protect some irregular shape, easy to damage or high requirements for packaging of steel products, such as precision parts and components.
- Specific description: the wooden box is made of thick wooden boards, and cushioning materials, such as foam, air cushion, etc., may be added inside to reduce the impact of vibration and collision on the product.
Anti-rust paper packaging
- Purpose: To prevent rust and corrosion of steel products, especially suitable for storage or transportation in a humid environment.
- Specific description: anti-rust paper usually contains rust inhibitors, can be in contact with the metal surface to form a protective film, blocking the erosion of moisture and oxygen.
Plastic film packaging
- Purpose: To provide basic protection against dust and moisture, commonly used for small steel products.
- Specific description: plastic film has a certain degree of flexibility and sealing, can be tightly wrapped in the product surface, effectively isolate the external environment.
Pallet packaging
- Purpose: To facilitate the stacking and handling of steel products, and improve logistics efficiency.
- Specific description: The pallet is usually made of wood or plastic, the steel products are placed on the pallet, and then the forklift and other tools can be used for handling and loading and unloading.
Factory container packing
- Purpose: It is used for mass transportation of iron and steel products, to protect the products and improve the utilization rate of transportation space.
- Specific description: Containers have a strong structure and good sealing, and can adapt to long-distance transportation and the conversion of multiple modes of transportation.
Anti-rust oil coating packaging
- Purpose: To form a layer of antirust oil film on the surface of steel and enhance the antirust ability.
- Specific description: evenly cover the steel surface with anti-rust oil by brushing or soaking to form a durable protective layer.
Metal Corner Protection Packaging
- Purpose: To protect the corners and edges of steel products from damage during handling and transportation.
- Specific description: Metal corner guards are usually installed on the corners of products, using welding, bolting and other methods to increase the strength and impact resistance of the corners.
Baling Steel's packaging will surely convey to you our dedication to quality. We understand the importance of packaging to the quality of steel products and transportation safety, so we strive for excellence in the selection of packaging materials, so that you do not have to worry about the loss of transportation, and fully feel our professionalism and dedication!
