    Seamless pipes can be manufactured to fit the different needs and specifications of the client. Seamless pipes are made with no weld and no seam.

    The main methods for manufacturing seamless pipes include

    1. Hot Rotary Piercing
    2. Extrusion Process Method

    Hot Rotary Piercing

    This is the most common method. The manufacturer first forces the steel through a piercing mill. Then a hot, solid, round billet pushes through the center to make the pipe hollow. The machine uses a piercing plug to create the hole.

    Extrusion Process

    Hot billets go through extrusion dies. Then, a metal bar in the machine, known as the mandrel, forms the billets. This forms the seamless pipes.

    Which Countries Manufacture Seamless Pipes in Bulk?

    Consumption of seamless steel pipes has increased dramatically across the world, especially in developing countries. These countries have been able to create the capacity and expand their productions to produce larger quantities of steel.

    How to transport seamless steel pipes?

    The pipes must be packaged and shipped carefully. This will prevent damage to the pipes. The pipes must also be sealed from too much moisture when packaging them in bundles, especially if they have a smaller diameter. This could cause the ends of the pipe to rust.

    Seamless steel pipes are typically exported by sea but can be transported in bundles by truck to job sites. A checking process occurs before the good is ready for export. In this process, a few things must be reviewed during packing and labeling. This may include breakage, security, excess weight, and proper identification markings. Another typical requirement for exporting is an export license.

    Where to Buy Seamless Steel Pipes?

    You may be able to find seamless steel pipes in small quantities in your area. But if you want to buy large quantities of seamless pipes, it is preferable to import directly from the manufacturers.

    The main products in grinding media are steel balls and grinding rods. At Camasteel, we sell Forged Steel grinding balls and Cast Iron grinding balls, in addition to steel grinding rods. The size of grinding balls can be a diameter between 20mm and 150mm, or 1 inch to 6 inch. The size of grinding rods can come in diameter between 40mm and 120mm. Forged steel grinding balls don’t lose shape or crack easily. They are durable and have great resistance.

    What is Grinding Media Used For?

    The industries that typically use Grinding Media are the mining and construction industries. Grinding Balls are used in ball mills. They are useful when breaking down and grinding materials such as rocks, cement, and others.

    Some markets that use grinding media include:

    • Mineral processing
    • Construction sector
    • Road construction
    • Ore crushing
    • Manufacturing process

    How to Determine Suitable Grinding Media

    steel grinding rod

    Grinding media has recommended characteristics, involving the shape, size, and composition. Steel grinding balls characteristics should include:

    Shape – The shape of grinding media is typically a sphere. This form is highly dense and does not chip easily. There are two shapes of grinding media that are most efficient. These include the ball shape and the cylinder rod.

    Diameter – The grinding ball should have a smaller diameter, but still large enough to get the best results. It can be more accurate when breaking down other material. The size of forged steel grinding balls will generally range from ¾ inch to 5 inches in diameter. The size of grinding rods will generally be between 1.5 to 4 inch in diameter. Also, the length should be a few inches shorter than the mill length. The size needed for each job may vary.

    Composition – The grinding material needs to be able to withhold high grinding methods and not wear or chip quickly. The grinding material should have a greater density than the material that is being ground. The material of the grinding media may vary, as well. Camasteel sells forged steel grinding balls, cast iron grinding ball, and steel grinding rods.

    How to Manufacture Steel Balls?

    steel ball manufactured form ball shape

    Camasteel uses a forging and stamping method to heat the metal to 1050 degrees Celsius. Then, it can be molded into the sphere shape. Between the forged steel grinding ball and the cast iron grinding ball, forged steel has better mechanical performance. The forged steel grinding ball must use the super wear resistant material to ensure its durability.

    When making the steel ball

    1. Heading: short lengths of wire are cut and then it is shaped into the form of a sphere.
    2. Deflashing: the ball rolls between two very heavy plates, typically cast iron plates, and becomes formed.
    3. Soft grinding: this is similar to the deflashing step, but a grinding stone is used to make the more precise form.
    4. Hot treating: the steel balls are put through heat and hardened.
    5. Descaling: removing any undesired residue from the ball.
    6. Hard grinding: this step helps with providing the perfect size and shape for the order.
    7. Finishing: giving the balls a smooth finish and coating to ensure that the product will last long.

    Which Countries Manufacture Steel Balls in Bulk?

  • What are U Beams and How to Buy U Beams

    What is a U Beam?

    hot rolled U Beam used in Construction Industry

    U Beam is a type of steel beam, which is a structural steel product with multiple uses mainly in the construction sector. U-Beams are also known as a parallel flange channel or C Beams. They typically can be welded together to form I-Beams. U Beams have a flat side with two smaller plates welded to it forming that U shape and the long flat side is typically mounted to a wall or flat surface to give support. U Beams are going to be more effective and stronger when placed vertically, but it still can be useful and strong when placed horizontally depending on the load.

    What is a U Beam Used For?

    steel structure with beam support

    U Beams are often used in construction and structural industries; they are often used in the process of building and give structure.

    U Beams can be used in just about any place that needs heavy weight support. Some of the major uses for U-Beams are:

    • Columns for support: typically mounted to another flat surface.
    • Lintels above doors
    • Beam supporting floor joists
    • Supporting main framework, walls, and roofs
    • Window and door frames
    • Automobiles
    • Manufacturing of machinery

    What is the Typical U-Beam Strength?

    Beam cross section building with U Beams

    Having the correct beam shape beam is important in having the right strength of the beams and overall structure. They are primarily placed vertically for maximum strength and support, but are also used horizontally in cross members. The U Beam is not always the best for long spans, as it is not supported as well, but it is for cross members.

    Shape of the beam

    The U Beam is also not the strongest beam shape. For example, compared to the I Beam, the U Beam is essentially half the I Beam strength, therefore it will not support as much weight. However, the U Beam can be useful depending on the needs of the project and how much weight needs to be supported.

    How to Manufacture U-Beams?

    electric arc furnace manufacture steel beams

    In factories, U-Beams are made by forcing metal through hot rollers to flatten it and then mold it into the shape of a U. There are two horizontal pieces, known as flanges, that are connected to a larger vertical piece, known as the web. These pieces are produced in the steel mill and then electric arc furnaces are used. This structural steel can either be hot-rolled or cold-rolled.

    Which Countries Manufacture Steel U-Beams?

    steel factory production line

    The main producers of Steel U-Beams are

    • China
    • United States
    • Italy
    • Japan
    • South Korea
    • Russia

    These countries have been able to create the capacity and expand their productions to produce larger quantities of steel, especially China. China’s steel imports are about 4% of all steel which shows that most of their steel comes from internal production at over 15 million metric tons. China produces about 49% of the 1.7 billion metric tons of steel produced worldwide each year and exports most of it.

    How to transport U Beams?

    U Beam steel channel U Beam shipment

    Large quantities of U Beams need cargo haulers that can handle heavy loads of steel in order to transfer them to different locations. When transporting steel beams, it is important to secure the beams to the hauler, and each other, so they do not shift and slide and make sure the weight is distributed evenly.

    Seamless steel pipes are typically exported by sea but can be transported in bundles by truck to job sites. A checking process occurs before the good is ready for export. In this process, a few things must be reviewed during packing and labeling. This may include breakage, security, excess weight, and proper identification markings. Another typical requirement for exporting is an export license.

    Where to Buy U-Beams?
