4. **According to Connection Method/Type:** Flanges are classified as follows:

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."

# **Meehanite® Almanite® WSH Wear and Abrasion Resisting Cast Iron**
## **Product Overview**
**Meehanite Almanite® WSH** is a premium **hybrid high-chromium-nickel white cast iron** manufactured under the stringent **Meehanite quality control system**, engineered specifically for applications requiring **exceptional combined resistance to severe abrasion, moderate impact, and elevated temperature environments**. The "WSH" designation signifies **White Special Hybrid** grade, representing an advanced alloy system that bridges the performance gap between conventional white irons and more expensive high-alloy materials.
This innovative material combines the superior abrasion resistance of high-chrome white irons with enhanced toughness and thermal stability through strategic nickel alloying and microstructure control. Almanite® WSH is specifically designed for applications where multiple wear mechanisms operate simultaneously and where service conditions are too demanding for standard white irons but don't justify the cost of exotic alloys.
