1,We Manufacturing processes are primarily classified into four types: 1:Forging, 2:Casting, 3:Cutting, 4:Rolling. 2,We can manufacture in accordance with these standards. Standards: GB Series (Chinese Standards), JB Series (Machinery Standards), HG Series (Chemical Industry Standards), ASME B16.5 (American Standards), BS4504 (British Standards), DIN (German Standards), and JIS (Japanese Standards). Internationally, there are two primary systems of pipe flange standards: the European system, represented by the German DIN standards (including those of the former Soviet Union), and the American system, represented by the US ANSI pipe flange standards. Other common standards include: the Chinese Ministry of Machinery Industry standards (JB series), the Ministry of Chemical Industry standards (HG series), the Chinese National Standard *GB/T 9112–9124-2010 Steel Pipe Flanges*, as well as US standards (ASME B16.5), British standards (BS4504), German standards (DIN), Japanese standards (JIS), and marine standards (CBM), among others. The nominal pressure ratings for the PN series are designated by "PN" and comprise the following nine levels: PN2.5, PN6, PN10, PN16, PN25, PN40, PN63, PN100, and PN160. The nominal pressure ratings for the Class series are designated by "Class" and comprise the following six levels: Class150, Class300, Class600, Class900, Class1500, and Class2500.

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. -: ASTM A525M Galvanized Steel Flange Product Information -:- For detailed product information, please contact sales. -: ASTM A525M Galvanized Steel Flange Synonyms -:- For detailed product information, please contact sales. -:

ASTM A525M Galvanized Steel Product Information -:- For detailed product information, please contact sales. -: ### **ASTM A525M Galvanized Steel: Metric Specification for Zinc-Coated Sheet by Hot-Dip Process** #### **1. Overview** ASTM A525M is the metric companion standard to ASTM A525, specifying requirements for steel sheet, zinc-coated (galvanized) by the hot-dip process in coil and cut lengths. This metric specification covers commercial qualities and designations with all measurements and requirements expressed in SI (International System) units. The standard provides a comprehensive framework for zinc-coated sheets used in applications requiring corrosion protection, with specific requirements for coating mass, mechanical properties, and dimensional characteristics in metric terms. #### **2. Chemical Composition** As with its imperial counterpart, ASTM A525M focuses on coating properties and mechanical performance rather than mandating specific chemical compositions. The base steel typically conforms to commercial quality designations with the following general characteristics: **Base Steel Types (Metric Equivalent):** - **Commercial Quality (CQ):** Maximum 0.15% carbon content - **Lockforming Quality (LFQ):** Enhanced formability for severe deformation - **Drawing Quality (DQ):** Suitable for moderate drawing operations - **Structural Quality (SQ):** Meets metric structural steel requirements **Typical Base Metal Chemistry Range:** | Element | Composition (%) | |---------|-----------------| | Carbon (C) | ≤ 0.15 | | Manganese (Mn) | ≤ 0.60 | | Phosphorus (P) | ≤ 0.035 | | Sulfur (S) | ≤ 0.035 | | Silicon (Si) | ≤ 0.030 | #### **3.
