Forged Steel Valve A105N is made from ASTM A105 carbon steel and is normalized to improve its mechanical properties. This material is widely used in manufacturing a broad range of forged steel valves, including gate, globe, and check valves. These valves are essential in various industries such as oil and gas, refinery, and petrochemical. It is suitable for high-temperature and high-pressure environments, and it offers excellent durability and strength. Compared to cast steel valves, which are made by pouring liquid metal into molds to create various sizes and complex shapes, forged valves are particularly suited for high-temperature and high-pressure applications due to their superior mechanical properties.
Let’s explore the details of A105N material and its performance in different industrial applications.
A105N is a carbon steel forging material that is widely used in manufacturing industrial valves and piping components. It has excellent mechanical properties and durability, making it suitable for high-temperature and high-pressure environments.
A105N ball valves are an industrial valve made from forged carbon steel, which is designated as ASTM A105N. The “N” in A105N means that the steel is normalized. Normalizing is a heat treatment process that improves the mechanical properties of the steel, making it tougher and more durable. A105N ball valves are used in many industries including oil and gas, petrochemical, power generation, and water treatment.
The A105 Gate Valve is a critical component in industrial piping systems that provides reliable isolation in a wide range of applications. These forged steel gate valves are made from ASTM A105 carbon steel and are forged to provide excellent mechanical properties and durability. They are normalized to enhance their performance and make them suitable for high-temperature and high-pressure condition. A105 gate valves are designed to either fully open or fully close the flow of fluid, providing a tight seal when closed and minimal flow resistance when open. They are built to last and provide long-term service in demanding conditions.
The A105 Globe Valve is a type of forged valve used extensively in industrial applications where precise flow control is required. These valves are made from ASTM A105 carbon steel and benefit from the forging and normalization processes, which improve their strength and durability. Globe valves are designed to control flow by moving a disk or plug in and out of the flow path. This allows for fine control over the fluid flow, making A105 globe valves perfect for applications that require precise flow control. They are built to last and perform well in a variety of industries, including oil and gas, petrochemical, and power generation.
The A105 Check Valve is designed to allow fluid flow in one direction while preventing backflow, which protects pumps and compressors in industrial systems. These valves are made from ASTM A105 carbon steel, which is forged and normalized to provide superior strength and increased durability. A105 check valves are critical in systems where backflow could cause damage or reduce efficiency. They automatically close when the flow reverses, preventing any backward movement of fluid. The reliable performance and sturdy construction of A105 check valves make them an essential component in a wide range of industrial applications, including chemical processing, oil and gas, and water treatment.
The A105 Control Valve is a critical component in industrial systems that regulates process variables such as flow, pressure, temperature, and liquid level. These control valves are made from ASTM A105 carbon steel and are forged to withstand high pressures and temperatures. The forging process uses mechanical forces to form the metal into the desired shape, enhancing durability, corrosion resistance, and tensile strength. The normalization process further improves their mechanical properties, ensuring they perform reliably and accurately. A105 control valves are designed to modulate the flow of fluids based on the control signal they receive, giving you precise control over your industrial processes. They are built to last and provide precise control in demanding applications across a variety of industries.
Measuring the wall thickness of A105 valves is important to make sure they will be safe to operate under specific pressure and temperature conditions. Here are the methods and standards we use to determine the wall thickness of A105 valves.
The wall thickness of valves is usually determined based on international standards such as:
ANSI/ASME B16.34: This standard gives you all the details you need for the design, materials, manufacturing, testing, and inspection of valves, including how to calculate the wall thickness.
API 602: This standard applies to small diameter forged steel valves and covers different types of connections, including BSP or NPT threaded connections, as well as socket weld (SW) connections.
To determine the wall thickness of the valve, you need to know the design pressure and temperature. You choose the pressure rating (e.g., 150, 300, 600, 800, , ) based on the working conditions, and then you look at the corresponding minimum wall thickness requirements in the relevant standards.
The properties of ASTM A105 carbon steel also impact the choice of wall thickness. You need to make sure the material has enough strength and toughness under the expected temperature and pressure conditions.
For valves that have already been manufactured, you can use the following methods to measure the actual wall thickness:
Ultrasonic Thickness Gauge: This is a non-destructive testing method that uses an ultrasonic probe to measure the wall thickness directly.
Caliper or Micrometer: For smaller valves or accessible parts, you can use precision measuring tools to measure the wall thickness directly.
The following is the ASME B16.34 Standard for each size of valve.
