wn Flange for Steel Pipes
Steel flanges provide an easy access for cleaning, inspection or modification. They usually come in round shapes but they can also come in square and rectangular forms. The flanges are joined to each other by bolting and joined to the piping system by welding or threading and are designed to the specific pressure ratings; 150lb, 300lb, 400lb, 600lb, 900lb, 1500lb and 2500lb.
Description
Flanges are usually manufactured in a circular shape, but because steel is extremely versatile, can be made in square and rectangular styles. Flange faces typically come in flat, raised, ring joint, and tongue-and-groove forms.
Weld-Neck Flange
As its name suggests, this type of flange is attached to a fitting by welding the neck of the flange. Due to its reinforcement and ability to transfer stress, it is suitable for high-pressure applications. These flanges may also be used in hostile environments with extreme temperatures.
Slip-on Flange
Again, made obvious by its name, this flange slips over pipes or fittings. It is manufactured with an inside diameter larger than its outside diameter. As its strength under pressure is about one-third of the Weld-Neck Flange, it is suited to low-pressure applications. Less accuracy is needed for cutting pipes when using Slip-On flanges. For this reason, it is commonly preferred over the Weld-Neck in low-pressure applications.
Socket Weld Flange
The Socket Weld Flange is similar to the Slip-on Flange. It is often used for high-pressure applications that are smaller in size. The fitting is inserted into the sockets of this flange and attached by a fillet weld at its top. This method can result in a smooth flow of the substance inside a pipe. With more stressful applications, another internal weld may be used.
Lap Joint Flange
Lap Joint flanges are often used in projects where they will need to be disassembled. This can be for cleaning or inspection purposes. Their pressure ability is likened to the Slip-on Flange. Rather than being welded, these types of flanges slip over a pipe or fitting.
Threaded Flange
Similar to slip-ons, Threaded Flanges can be attached by threading the bore. With no need for welding, this places them at a distinct advantage. Threaded Flanges are common in low-pressure applications. As it is often fixed to a fitting through threads, these flanges will not be suited to high-pressure use.

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!
