A flange—also referred to as a flange plate or rim—is a component used to connect shafts to one another, or, more commonly, to join the ends of pipes. Flanges are also utilized at the inlet and outlet ports of equipment to facilitate connections between two devices—for instance, the flange on a speed reducer. A "flange connection" or "flanged joint" refers to a detachable joint assembly comprising three interconnected elements—a flange, a gasket, and bolts—that together form a sealed structural unit. In the context of piping systems, a "pipe flange" specifically denotes a flange used for plumbing within the installation; when applied to equipment, it refers to the inlet or outlet flange of that specific device. Flanges feature a series of holes through which bolts are inserted to securely fasten the two flanges together, while a gasket placed between the flanges ensures a leak-proof seal. Flanges are broadly categorized into three types: threaded (screw-in) flanges, welded flanges, and clamp-type flanges. Flanges are invariably used in pairs; threaded flanges are suitable for low-pressure piping applications, whereas welded flanges are required for systems operating at pressures exceeding 4 kilograms per square centimeter. A sealing gasket is inserted between the two flange plates, which are then firmly secured using bolts. The thickness of a flange—as well as the specifications of the bolts used to fasten it—vary depending on the specific pressure rating required for the application. When connecting equipment such as water pumps or valves to piping systems, the corresponding connection points on these devices are often manufactured in the shape of a matching flange; this method of attachment is also referred to as a "flange connection." Generally, any connecting component that utilizes bolts to join and seal the perimeters of two flat surfaces—such as the joints in ventilation ducts—is termed a "flange"; such components may collectively be classified as "flange-type parts." However, since such a connection often constitutes merely a *portion* of a larger device—for instance, the interface between a flange and a water pump—it would be inappropriate to classify the entire water pump itself as a "flange-type part." Conversely, smaller components—such as valves—that feature such flanged interfaces may indeed be appropriately categorized as "flange-type parts." -:- For detailed product information, please contact sales. -: EN 1.1100 High Manganese Pressure Vessel Carbon Steel Flange Product Information -:- For detailed product information, please contact sales. -: EN 1.1100 High Manganese Pressure Vessel Carbon Steel Flange Synonyms -:- For detailed product information, please contact sales. -:

EN 1.1100 High Manganese Pressure Vessel Carbon Steel Product Information -:- For detailed product information, please contact sales. -: **Product Name:** EN 1.1100 High Manganese Carbon Steel Plate for Pressure Vessels **Overview:** EN 1.1100 is a high-manganese, non-alloy **carbon steel specifically designed for the construction of welded pressure vessels**. It is classified as a **fine-grained steel** and is primarily delivered in the **normalized (N) or thermomechanically rolled (M) condition** to ensure a homogeneous microstructure and enhanced toughness. This grade is engineered to provide an optimal balance of strength, weldability, and notch toughness at low temperatures, making it a fundamental and widely used material for a broad range of pressure-containing equipment operating under moderate conditions. **Key International Standards:** * **Primary Standard:** **EN 10028-2:2017** - Flat products made of steels for pressure purposes - Part 2: Non-alloy and alloy steels with specified elevated temperature properties. * This standard supersedes the older EN 10222 forgings standard for plate products. EN 1.1100 corresponds to steel grade **P355GH** under this standard. * **Key Designation:** **P355GH** * **P:** Steel for pressure purposes. * **355:** Minimum specified yield strength (ReH) in MPa at room temperature for thicknesses ≤ 16mm. * **G:** Signifies fine grain practice. * **H:** Indicates suitability for use at elevated temperatures. * **Important Quality:** The 'GH' designation implies mandatory impact testing with values to be reported on the inspection certificate (though not necessarily guaranteed to a specific minimum at low temperature unless a sub-grade like N, NL, or ML is ordered). * **Equivalents & Comparisons:** * **ASTM:** **SA-516 Grade 70** (the most direct global equivalent in terms of application and strength). * **ASME:** SA-516 Grade 70. * **JIS:** SPV355. * **GB/T:** Q355R (China's pressure vessel steel equivalent). **Chemical Composition (Ladle Analysis, % by weight, typical maximum values per EN 10028-2):** The composition is tightly controlled for weldability, strength, and grain refinement. * **Carbon (C):** ≤ **0.20%** (Controlled for weldability and toughness). * **Manganese (Mn):** **0.90 - 1.50%** (The "high manganese" characteristic, providing solid solution strengthening). * **Phosphorus (P):** ≤ **0.025%** (Low for improved toughness). * **Sulphur (S):** ≤ **0.015%** (Very low to enhance weldability and through-thickness properties). * **Silicon (Si):** **0.10 - 0.50%** (Deoxidizer). * **Aluminum (Alt):** ≥ **0.020%** (Mandatory for fine grain practice via aluminum nitride formation). * **Nitrogen (N):** ≤ **0.015%**. * **Carbon Equivalent (CEV):** Typically ~0.40%, which is moderate, requiring controlled welding procedures for thicker sections. **Physical & Mechanical Properties (for normalized condition, thickness ≤ 16mm example):** * **Yield Strength (ReH):** ≥ **355 MPa** (Minimum at room temperature. Decreases with increasing plate thickness). * **Tensile Strength (Rm):** **470 - 630 MPa**. * **Elongation (A):** ≥ **21%** (Minimum on longitudinal test piece). * **Impact Energy (KV):** Values are tested and reported. For standard P355GH, a typical test temperature is **0°C or +20°C**. To guarantee low-temperature toughness, sub-grades must be specified: * **P355N:** Impact tested at **-20°C**. * **P355NL:** Impact tested at **-50°C** (Normalized). * **P355ML:** Impact tested at **-50°C** (Thermomechanically rolled). * **Elevated Temperature Yield Strength (Rp0.2):** Guaranteed minimum values are specified in EN 10028-2 for temperatures up to **300-400°C** (e.g., ~280 MPa at 300°C). * **Density:** ~7.85 g/cm³. * **Modulus of Elasticity:** ~210 GPa at 20°C. **Product Features:** 1. **Pressure Purpose Design:** Specifically manufactured and tested to meet the stringent quality and homogeneity standards required for pressure vessel safety. 2. **Fine Grain Structure:** The mandatory aluminum treatment ensures a fine austenitic grain size, which translates to better toughness and more consistent mechanical properties. 3. **Good Weldability:** Its moderate carbon equivalent allows for reliable welding using all common methods (SAW, SMAW, GMAW). Post-weld heat treatment (PWHT) is commonly applied for stress relief, especially in thicker sections. 4. **Elevated Temperature Service:** The 'H' designation means it has specified minimum yield strength values at temperatures up to 300-400°C, making it suitable for many process vessels. 5. **Cost-Effectiveness:** As a non-alloy carbon-manganese steel, it provides excellent performance for a wide range of applications at a competitive cost. **Typical Applications:** EN 1.1100 (P355GH/N/NL/ML) is a workhorse material for static pressure equipment across multiple industries: * **Process Industry:** **Columns, reactors, separators, heat exchanger shells, and storage tanks** in oil & gas, petrochemical, and chemical plants. * **Power Generation:** **Steam drums, feedwater heaters, deaerators, and other boiler pressure parts** (non-firing areas) in thermal power plants. * **Food & Beverage and Pharmaceutical:** **Process vessels, fermentation tanks, and storage tanks** requiring certified material traceability. * **Cryogenic Applications (with NL/ML grades):** **Low-temperature storage tanks** for liquids like CO2, LPG, and ethylene (down to -50°C design temperature). **Available Forms & Quality Supplements:** * **Forms:** Exclusively supplied as **hot-rolled plates**. * **Delivery Condition:** **Normalized (N)** is most common for general purposes. **Thermomechanically rolled (M)** is an option for thinner gauges and improved toughness. * **Mandatory Testing:** Full traceability with destructive testing (tensile, impact) per heat and thickness range. **Non-destructive ultrasonic testing (UT)** of plates per EN 10160 is a standard requirement. * **Certification:** Supplied with a **full Inspection Certificate 3.1 per EN 10204**, which is mandatory for pressure equipment under the European Pressure Equipment Directive (PED). --- **Critical Procurement Note:** For pressure vessel construction, it is essential to specify not only **P355GH** but also the required **sub-grade (N, NL, ML)** based on the **Minimum Design Metal Temperature (MDMT)** of the vessel. The mechanical properties are strictly thickness-dependent, and the applicable values for the ordered thickness must be verified from the standard tables. Compliance with the Pressure Equipment Directive (PED) requires the material to bear the CE marking and be accompanied by the appropriate conformity documentation. -:- For detailed product information, please contact sales. -: EN 1.1100 High Manganese Pressure Vessel Carbon Steel Specification Dimensions Size： Diameter 20-1000 mm Length <5804 mm Size:We can customized as required Standard： Per your request or drawing We can customized as required Properties（Theoretical） Chemical Composition -:- For detailed product information, please contact sales. -: EN 1.1100 High Manganese Pressure Vessel Carbon Steel Properties -:- For detailed product information, please contact sales. -:
