What is Seamless Steel Pipe?

Seamless Steel Pipe is an industrial steel product with multiple uses. Seamless steel pipe is a pipe with a circular and hollow center that has no seams around the end. It is typically available in carbon steel and stainless steel. It has great resistance to wear and corrosion, and doesn’t rust easily. Seamless steel pipes can be hot-rolled or cold-rolled. Cold-rolled can be circular or shaped pipe.

What is Seamless Steel Pipe Used For?

The industries that use seamless steel pipes most often include:

• Automotive
• Oil and gas
• Construction
• Fertilizer
• Chemical
• Environmental technologies
• Ship building
• Mechanical
• Boiler industry

They can be used in various places such as underground, in walls, labs, and many other structures. The most popular uses of this product are

• Transport fluids (water, waste, gas, etc.)
• Heat transfer
• Ship building
• Hydraulic braking systems
• Pumps
• Boiler
• Much more!

What are the benefits of Seamless Steel Pipe?

Seamless pipes can be more expensive to produce and purchase, but it is more reliable and there are many benefits including

1. They are very durable and withhold high levels of pressure, about 20% higher pressure than welded pipes. They are also very resistant to corrosion.
2. Seamless pipes harden during the manufacturing process, so they generally don’t need heat treatment.
3. A seamless pipe can be used in place of a welded pipe, but a welded pipe cannot be used in place of a seamless pipe.
4. Seamless pipes have a more solid round cross section than welded pipes.
5. It has great strength and can support large amounts of weight.

How to Manufacture Seamless Steel Pipes?

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?

The main producers of seamless steel pipes are

• China
• Spain
• Italy
• United States
• India
• Japan
• Russia
• United Kingdom

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. They can issue certifications and provide cost savings which is better than buying the steel in small quantities locally or from a distributor.

What is Grinding Media?

Grinding media are commonly used for the extraction of precious metals, when processing ore minerals. Grinding media are of two types-steel balls and grinding rods. The size of grinding steel 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 do not lose shape or crack easily. They are durable and have great resistance. At Camasteel, we sell forged steel grinding balls and cast iron grinding balls, in addition to steel grinding rods. 

Quality Steel Grinding Media Balls

What is Grinding Media Used For?

Grinding Media are used in the mining and construction industries to crush or grind materials in a mill. In the mining industry, grinding media are used to extract precious metals in minerals. Also, 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 Do I Choose a Grinding Media?

The choice of grinding media should be based on the following recommended characteristics , which include, the shape, size, and composition. Grinding media  characteristics are explained below;

Grinding Media - Shape

The shape of a grinding media ball 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.

Spherical Shaped Grinding Media Ball

Grinding Media- Diameter

The grinding media 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.

High Quality Grinding Rods for Bulk Purchase

Grinding Media- Composition 

The grinding media needs to be able to withhold high grinding methods and not wear or chip quickly. The grinding media 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?

In the manufacturing of grinding steel balls, Camasteel uses a forging and stamping method to heat the metal to 1050 degrees Celsius. Then, it can be moulded 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.

Making of Quality Grinding Steel Balls

Process in Manufacturing Grinding Steel Balls

1. Heading

   Short lengths of wire are cut and then it is shaped into the form of a sphere.

2. Deflashing

   This step involves rolling the balls between two very heavy plates, typically cast iron plates, which leads to its formation.

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

   This is the process of 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

   This step involves giving the balls a smooth finish and coating to ensure that the product will last long.

Which Countries Manufacture Steel Balls in Bulk?

The main producers of steel ball grinding media are

• China
• Japan
• Belgium
• India
• Germany
• United States
• United Kingdom

The use and demand for grinding media has increased, especially in developing countries. These countries have been able to create the capacity and expand their productions to produce larger quantities of steel, especially China.

What is Pre-Painted Galvanized Iron (PPGI)?

Pre-Painted Galvanized Iron (PPGI) is an industrial steel product with multiple uses. It is a form of galvanized iron (GI) that is also dipped into zinc. However, the zinc coat is pre-painted in the factory instead of waiting until after the steel is formed. Applying a zinc coat prevents rusting. PPGI is also known as metallic coated steels, or pre-coated steel. This product will typically come in the form of a coil. This steel is often not costly and can last for a long period of time.

What is PPGI used for?

Pre-painted galvanized iron has multiple uses. The most popular uses of this product include applications such as:

Cost Effective

There is a low cost to this product because there is not an additional task or preparation of the product after the steel is formed; it is ready to use upon delivery.

Rusting

The product is pre painted with a zinc coating that protects the base from rusting and corrosion. It is unlikely for the steel to experience damage for a while after installation.

Flexibility

PPGI is flexible steel used for many applications in many industries.

How to Manufacture Pre-Painted Galvanized Iron?

The process of manufacturing PPGI involves multiple steps, first going through pre-cleaning and enters the accumulator including processes of

1. Degreasing
2. Brushing
3. Washing and drying
4. Chemical coating
5. Refined coating and primer

After a coat of prime, the sheet gets painted. Then leaves the accumulator and enters quality controlling and finishing the coil including processes of

1. Cooling
2. Cutting
3. Coiling

The typical thickness of a PPGI sheet can range from about 0.125 mm to 4.0 mm. At Camasteel, you can buy PPGI ranging from a thickness of 0.12 mm to 2.0 mm and a width ranging from 600 mm to 1250 mm. Camasteel offers great flexibility in the dimensions and specifications of their PPGI order.

What is a U Beam?

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?

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?

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?

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?

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?

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?

You may be able to find U-Beams in small quantities in your area. But if you want to buy large quantities of U-Beams, it is preferable to import directly from the manufacturers. They can issue certifications and provide cost savings which is better than buying the steel in small quantities locally or from a distributor.
