Gasket Monel 400: A robust alloy offering exceptional corrosion resistance, especially in marine and acidic environments.
A metal-wound gasket, also known as a spiral wound gasket, is a high-performance seal typically used in high-pressure and high-temperature applications. Its unique design and construction make it suitable for a wide range of industrial sealing applications.
The gasket is comprised of a mix of metallic and filler material. The winding process involves spirally winding a preformed metal strip and filler material. The metal strip provides structural integrity and resilience, while the filler material ensures the gasket is leak-proof.
Metal strips are often made of stainless steel or other corrosion-resistant metals, while the filler materials could be flexible graphite, PTFE, or other heat-resistant materials. The resulting spiral structure exhibits excellent recovery characteristics and is highly resistant to temperature, pressure fluctuations, and corrosion.
One of the major advantages of metal-wound gaskets is their ability to maintain a seal even under severe conditions, making them an ideal choice for applications in the petrochemical, refinery, and power generation industries.
Additionally, the gasket’s design can be customized to meet specific flange configurations and operating conditions, ensuring optimal performance. However, it is crucial to select the appropriate metal and filler materials to match the application to ensure longevity and sealing effectiveness.
Flanges Hastelloy C276: A pipe flange is a crucial component used in piping systems to connect sections of pipe or to connect a pipe to other equipment such as valves, pumps, and pressure vessels. Flanges provide an easy access point for inspection, modification, and cleaning of the system.
Constructed typically from forging materials like stainless steel, carbon steel, or other alloys, pipe flanges come in various sizes, shapes, and pressure ratings to suit different applications. The most commonly used types include slip-on flanges, weld neck flanges, blind flanges, socket weld flanges, threaded flanges, and lap joint flanges.
Each type of flange has its own advantages. For instance, slip-on flanges are easy to install and are used in low-pressure systems, while weld neck flanges are designed for high-pressure, high-temperature, or high-stress applications due to their robust construction.
Pipe flanges are typically joined together by bolting and sealed with a gasket in between to prevent leaks. The number, diameter, and length of the bolts depend on the flange’s size and the pressure of the system.
In addition, flanges can be customized to meet specific requirements. Custom flanges can be designed with unique faces, bore sizes, and configurations.
Overall, pipe flanges are essential elements in many industrial applications, including petroleum, chemical, shipbuilding, and power generation industries, providing flexibility, strength, and reliability to piping systems.
The corrosion resistance of Hastelloy C-276 is suitable for various chemical process industries containing oxidizing and reducing media. The higher content of molybdenum and chromium makes the alloy resistant to chloride ion erosion, and the tungsten element further improves its corrosion resistance. C276 is one of the few materials that can withstand corrosion from damp chlorine gas, hypochlorite, and chlorine dioxide solutions. This alloy has significant corrosion resistance to high concentrations of chloride solutions, such as iron chloride and copper chloride.
Alloy C276 has been widely used in the fields of chemical and petrochemical industries, such as in components and catalytic systems that come into contact with chloride containing organic compounds. This material is particularly suitable for use in high-temperature, impurity mixed inorganic and organic acids (such as formic acid and acetic acid), and seawater corrosive environments.
How are bolts made of Hastelloy C-276 material produced?
The production process of twin-headed bolts includes a series of precise manufacturing steps to ensure their dimensional accuracy and mechanical properties. The following is the general process of producing double-headed bolts:
Preparation of raw materials:
• Material selection: Select suitable steel (such as carbon steel, stainless steel or alloy steel) as raw materials to ensure that they meet the mechanical and chemical performance requirements of the product.
• Cutting: Cut the raw material into steel bars or steel wire of the required length.
Forming:
• Cold Heading: The heading of one or both ends of the steel rod is thickened by the cold heading machine to form a preliminary bolt head or threaded part. This step can improve the strength and toughness of the material.
• Turning: Use the lathe for further processing to ensure that the size and shape of the bolt meet the requirements.
Thread processing:
• Thread Rolling: The two ends of the bolt are processed by the thread rolling machine to form the required thread. The wire rolling process can not only improve the strength of the thread, but also ensure the accuracy and surface finish of the thread.
• Thread Cutting: In some cases, thread cutting processes are used to process threads, especially for small batches or bolts with specific thread specifications.
Heat treatment:
• Quenching and Tempering: Heat treatment of bolts according to material and performance requirements to improve their hardness and strength.
• Annealing: Sometimes annealing is needed to eliminate internal stress and improve the processability of the material.
Surface treatment:
• Electroplating: such as galvanized, nickel-plated or chrome-plated to increase the corrosion resistance and aesthetics of bolts.
• Phosphating: Improve anti-corrosion performance and lubrication.
• Coating: such as spray paint or plastic spraying, provide an additional protective layer.
Inspection and testing:
• Size check: Use measurement tools (such as calipers and thread gauges) to check the size and thread accuracy of bolts.
• Mechanical performance test: conduct tensile, hardness and torque tests to ensure that the mechanical properties of the bolts meet the standards.
• Surface quality inspection: Check the quality of the surface treatment to ensure that there are no defects and uniformity.
Packaging and storage:
• Cleaning: Clean the bolts to remove oil and residue from the production process.
• Packaging: According to customer requirements and standards, the bolts are classified and packaged to prevent damage during transportation and storage.
• Labels and logos: Mark the specifications, quantity and batch numbers on the package for traceability and management.
The above is the general process of the production of double-head bolts. The specific process steps may be adjusted according to the special requirements of the product and different production equipment.
