Hardware Knowledge Hall: The production and advantages of the stone cage network

Production: The stone cage net is made of high-corrosion-resistant, high-strength, ductile low-carbon steel wire or PVC-coated steel wire. The box-shaped structure made from the net is a stone cage. According to ASTM and EN standards, the diameter of the low carbon steel wire used varies according to engineering design requirements. Generally, it is between 2.0 and 4.0 mm. The tensile strength of the steel wire mesh is not less than 38 kg/m2, and the weight of the metal plating is generally higher than 245 g/m2. The diameter of the edge line of the gabion mesh is generally larger than the diameter of the wire. The length of the double-wire stranded portion shall not be less than 50 mm to ensure that the metal plating and the PVC coating of the stranded steel wire are not damaged.

Uses: Stone cage net can be used for slope support, foundation pit support, mountain rock face hanging net shotcreting, slope planting (greening), railway expressway isolation guard net, it can also be made into box cage, mesh mat, with Anti-scour protection of Yujiang River, dams and seawalls, and cages for reservoirs and river closures. The most serious disaster in rivers is that water flows to wash the river bank and destroy it. The flooding caused by it causes a lot of loss of life and property and a lot of soil erosion. Therefore, in dealing with the above problems, the application of the ecological grid structure is one of the best solutions, which can permanently protect the river bank.

Advantages: 1. The flexible structure can adapt to the change of the slope without being damaged, and has better safety and stability than the rigid structure; 2. It has strong anti-scour ability and can withstand the maximum water flow speed of up to 6m/s; The structure is water-permeable in nature, and has strong inclusiveness to the natural action and filtration of groundwater. Suspended matter and sludge in the water can be deposited in the rock-filled joint, thereby facilitating the growth of natural plants and gradually recovering. The original ecological environment.

The gabion net is a mesh format made of wire or polymer wire that holds the stone in place. The wire cage is a mesh woven from iron wire or a welded structure. These two structures can be electroplated and the braided wire box can be additionally coated with PVC. The anti-weathering hard rock is used as a filler, and it will not be broken quickly due to abrasion in the stone box or stone cage sinking. Stone cages with different types of stone have different characteristics. The multi-angled stone can be interlocked well with each other, and the stone cage filled with it is not easily deformed.

Valve And Pump Components

Valves and pumps are critical components in various industrial systems, enabling the control and movement of fluids across a multitude of applications. The manufacturing of these components often involves precision and robust material selection to meet specific operational demands. Here, we explore the various manufacturing processes, materials used, and use cases of valve and pump components.
Materials Used in Valve and Pump Manufacturing
Stainless Steel: Offers excellent corrosion resistance and strength, making it ideal for valves and pumps used in corrosive environments or in applications requiring cleanliness such as food processing or pharmaceuticals.
Carbon Steel: Provides strength and durability at a lower cost than stainless steel, suitable for high-pressure environments and applications where corrosion is not a major concern.
Ductile Iron: Combines the machinability of cast iron with some degree of ductility, ideal for larger valves and pumps where cost-effectiveness and high fluid pressure capabilities are necessary.
Aluminum Alloys: Known for their lightweight and corrosion resistance, aluminum alloys are used in applications requiring good strength-to-weight ratios such as in automotive or aerospace pump components.
Bronze and Brass: Typically used in smaller valve components, these materials offer good corrosion resistance and are commonly found in water handling applications.
Use Cases for Valve and Pump Components
Valves and pump components are integral to a wide range of industries:
  • Oil and Gas: High-pressure valves and robust pump systems for handling and processing crude oil and natural gas.
  • Water Treatment: Valves and pumps designed to manage, direct, and treat water in municipal and industrial treatment systems.
  • Chemical Processing: Components that withstand aggressive chemicals and high temperatures are crucial in this sector.
  • HVAC: Pumps and valves that facilitate the efficient movement and regulation of air and coolant in heating, ventilation, and air conditioning systems.
  • Agriculture: Pumps used for irrigation and pesticide/herbicide deployment, requiring materials resistant to various chemical exposures and environmental conditions.
