    Advantages and disadvantage of EN 1092 Flanges

    EN 1092 is a European standard for flanges, which specifies the technical requirements for circular flanges and flanged parts. Some potential advantages of using EN 1092 flanges include that they are:

    • Designed to be interchangeable, which means that flanges from different manufacturers can be used together, provided they conform to the standard.
    • Easy to identify, thanks to the standardized markings on the flange face, which indicate the type, pressure class, and material of the flange.
    • Suitable for a wide range of applications, including petrochemical, oil and gas, and power generation.

    As with any type of flange, there are also some potential disadvantages to consider when using EN 1092 flanges, such as:

    • The cost, which can be higher than other types of flanges, due to the need to meet the technical requirements of the standard.
    • Limited availability, as not all flange manufacturers produce flanges to the EN 1092 standard.
    • The need for specialized tools and equipment, such as flange spreaders and flange aligners, to install and maintain EN 1092 flanges.

    The advantages and disadvantages of using EN 1092 flanges will depend on your specific application and requirements. It is always a good idea to consult with a flange expert or engineer to determine the best type of flange for your needs.

    What are the different types of EN 1092 flanges?

    EN 1092-1 flanges are available in a number of different types, including:

    EN 1092-1 Type 01: Plate (slip-on) flanges for welding Type 01 flanges are plate (slip-on) flanges that are designed for welding. These flanges have a circular hub and a flat rim, and they are attached to the pipe by welding the hub to the pipe.
    EN 1092-1 Type 02: Loose plate flanges with weld-on plate collar Type 02 flanges are loose plate flanges that have a weld-on plate collar. These flanges are similar to type 01 flanges, but they are not welded directly to the pipe. Instead, they are attached to the pipe using a separate collar that is welded to the pipe.
    EN 1092-1 Type 04: Loose plate flanges with weld-neck collar Type 04 flanges are similar to type 02 flanges, but they have a weld-neck collar instead of a plate collar. These flanges are attached to the pipe using a weld-neck collar that is welded to the pipe.
    EN 1092-1 Type 05: Blank (blind) flanges Type 05 flanges are blank (blind) flanges. These flanges are solid and do not have a central hole. They are used to close off the end of a pipe or other fitting.
    EN 1092-1 Type 11: Weld-neck flanges Type 11 flanges are weld-neck flanges. These flanges have a circular hub with a tapered, neck-like projection that is welded to the pipe.
    EN 1092-1 Type 13: Hubbed threaded flanges Type 13 flanges are hubbed threaded flanges. These flanges have a threaded hub that is used to attach the flange to the pipe using bolts.
    EN 1092-1 Type 21: Integral flanges Type 21 flanges are integral flanges. These flanges are formed by rolling or forging, and they are integral with the pipe to which they are attached.
    EN 1092-1 Type 32: Weld-on plate collars Type 32 flanges are weld-on plate collars. These collars are used to attach type 02 flanges to pipes, by welding the collar to the pipe.
    EN 1092-1 Type 33: Lapped pipe ends Type 33 flanges have lap-joint ends, which means that the ends of the pipes are overlapped and then attached to the flange with a lap-joint stub end. This type of flange is often used in low-pressure systems where the flange does not need to be sealed.
    EN 1092-1 Type 34: Weld-neck collars Type 34 flanges have weld-neck collars, which means that the flange has a neck that extends from the body of the flange and is used to attach the flange to a pipe by welding. This type of flange is often used in high-pressure systems where a tight seal is required.

    Each type of flange has a different design and is used in different applications. For example, slip-on flanges are often used for low-pressure piping, while weld neck flanges are used in high-pressure systems. It is important to choose the right type of flange for your application to ensure a secure and reliable connection.

    Material of EN 1092 Flanges

    EN 1092 flanges are typically made of cast or forged carbon steel, stainless steel or other alloy materials. The specific material used depends on the application and design specification of the flange. It is important to select the right material for the flange to ensure that it is strong and durable enough to withstand the pressure and temperature conditions in which it will be used.

    • Raw material inspection – The key raw material used to produce flanges is billet or hot rolled bar stock. All raw materials purchased are supplied with test reports in accordance with British Standards with full traceability. This is the first mandatory step in the flange production process to ensure good quality. The raw materials are retested in-house to ensure chemical composition, mechanical properties and metallographic analysis.
    • Cutting of raw materials – Correct and strict control of cutting sizes and proportions ensures full cost control.
    • Heating – This is a very important step for the quality of the flanges. It is necessary to keep detailed records of heating temperatures to avoid overheating. Overheating can damage the structure of the metal and the mechanical properties of the raw material.
    • Forging – The forging process is divided into free forging and die forging. The forging time and strength of flanges vary for different pressure classes.
    • Heat treatment-The purpose of heat treatment is to eliminate the stress inside the flange and make the density more uniform. Careful recording of heat treatment temperature and cooling time is the key.
    • Inspection of forging blanks – After the heat treatment process, select batch samples are tested again for chemical composition and mechanical properties to ensure that all items pass.
    • Machining of forging blanks – During machining, inspection is performed along with machining to ensure that each part of the flange is qualified. Machining is performed on CNC and/or lathes.
    • Finished Product Inspection – The finished product will be inspected 100% prior to delivery to ensure that the goods meet EN 1092, ASME, EN or customer standards.
    • Documented Documentation – The entire production process and quality checks at different levels are documented according to ISO compliant standard operating procedures. This is the guarantee of good quality.
    • Test certificates: As we are an ISO and PED certified manufacturer, we can issue test certificates for all goods upon delivery and inspection in accordance with British Standards.
    • Packaging: All forgings and flanges are packed in wooden boxes or crates or pallets to ensure safe movement of the goods.

    Production process of EN 1092 casting flange

    The production process of a EN 1092 casting flange typically involves several steps, including the creation of a mold or pattern, the casting of the flange using molten metal, and various finishing and quality control steps. To begin the process, a mold or pattern is created using a material such as wood or metal. This mold or pattern will be used to create the shape of the flange, and will typically be made to precise specifications to ensure that the final product meets the desired dimensions and specifications. Once the mold or pattern is ready, the casting process can begin. This typically involves melting the metal that will be used to create the flange, such as iron or steel, and pouring the molten metal into the mold or pattern. The metal is then allowed to cool and solidify, taking on the shape of the mold or pattern. After the casting process is complete, the flange will typically undergo various finishing and quality control steps. This may include machining or grinding to achieve the desired dimensions and surface finish, as well as testing to ensure that the flange meets the required specifications and standards. Overall, the production process for a EN 1092 casting flange is a highly precise and technical process that requires a thorough understanding of metallurgy, casting techniques, and quality control processes.

    Manufacturing process of EN 1092 plate cutting flange

    The process here is relatively simple, and the key raw material is hot rolled plate. The process is mainly used to produce lower thickness sliding plate flanges and blind flanges. All plates purchased are accompanied by a test certificate to German Standards. The circles are cut from the plates. No heat treatment is involved in the flange manufacturing process. Drilling and machining is carried out on the circles to obtain the required dimensions. The goods are visually inspected and marked in accordance with the relevant standards.

    Marking of EN 1092 Flanges

    EN 1092 flanges are marked with various important information such as the material, size, pressure rating, and manufacturer. The marking may be laser-etched or stamped onto the flange, and typically includes the following:

    • Flange standard: EN 1092-1, EN 1092-2.
    • Material grade: The material grade of the EN 1092 flange, such as A105 for carbon steel or F304 for stainless steel.
    • Nominal size: The size of the EN 1092 flange, such as 4″ or 8″.
    • Pressure rating: The pressure rating of the EN 1092 flange, such as 150# or 300#.
    • Manufacturer’s name or logo: The name or logo of the manufacturer of the EN 1092 flange.
    • Country of origin: The country where the EN 1092 flange was manufactured, such as “Made in USA” or “Made in China”.
    • Heat number or serial number: A unique number or code assigned to the flange by the manufacturer for traceability purposes.

    In addition to the above information, EN 1092 flanges may also be marked with additional details such as the flange type, threading specifications, and quality control certifications

    Packing of EN 1092 Flanges

    EN 1092 flanges are placed in wooden or cardboard boxes with protective covers on both ends, and pearl cotton or cardboard is placed on each layer to protect the flanges during transportation. Depending on the size and weight of the flanges, they can also be placed on pallets for easier handling and transportation. The method of transportation will depend on the distance the flanges need to be transported and the manufacturer’s or supplier’s preference. They can be transported by truck, train or cargo ship.

    Inspection and measurement of EN 1092 Flanges

    EN 1092 flange inspection includes: appearance inspection, dimensional inspection, material inspection, quality certificate inspection and other parts.

    1). Appearance inspection

    The casting surface should be smooth, and there should be no forging scars, cracks and other defects. The casting surface should be clean of sticky sand, oxide skin, etc., and no defects affecting the performance of the casting (such as cracks, shrinkage, slag, etc.). Machined surface shall not have burrs, harmful scratches and other defects that reduce the strength and connection reliability of the flange. The sealing surface of the ring connection surface flange shall be inspected one by one, and the two sides of the groove shall not have surface defects such as cracks, scratches and bruises caused by machining.

    2). Inspection of materials

    The inspection of material is carried out by hand-held spectrum.

    3). Inspection of flange size How to measure the size of flange?

    If the center of the flange connection hole is large, the larger deviation will affect the sealing operation of the piping system. If there is a large stress (e.g. earthquake), it may also damage the flange or the insulator it is connected to; therefore, in order to bett
