Material and Manufacturing:

Materials

● Primary Material: Generally, HT200 cast iron is selected. This material has good strength, enabling it to withstand the large tensile forces and external forces generated during ship mooring, ensuring the stability of the bollard. It also has excellent wear resistance, so that friction with mooring ropes during long - term use will not easily cause surface damage. Its casting performance is outstanding, facilitating casting into complex T - shaped structures. Moreover, the cost is relatively low, which can effectively control the product cost while ensuring performance.

● Auxiliary Materials: The anchor rods usually adopt high - strength carbon steel or alloy steel, which have high tensile strength and good toughness, ensuring the firm connection between the bollard and the dock foundation. Nuts and washers are generally made of metal materials that match the material of the anchor rods to guarantee the reliability and stability of the connection. The core filling material can be concrete or other high - strength filling materials, which are used to enhance the overall structural strength of the bollard and improve its impact and deformation resistance.

Manufacturing

● Mold Making: Based on the design dimensions and shape of the T - shaped cast - iron bollard, materials such as wood, metal, or plastic are used to make the mold. For mass production, metal molds are often employed. These metal molds have high precision and strong durability, ensuring the dimensional accuracy and surface quality of the castings.

● Casting Process: Processes like sand casting or lost - foam casting are adopted. In sand casting, the prepared molding sand is filled into the mold, compacted, and then the mold is removed to form the casting cavity. In lost - foam casting, a foam plastic model is first made, coated with refractory materials, and then buried in dry sand. When pouring, the foam plastic model gasifies and disappears, and the molten metal fills the cavity. The molten cast - iron liquid is heated to an appropriate temperature, generally around 1400℃ - 1500℃, and then poured into the casting cavity. After cooling and solidifying, the blank of the T - shaped cast - iron bollard is formed.

● Machining: The blank is first rough - machined to remove excess burrs, flash, etc., leaving a margin for subsequent finishing. Then, finishing operations are carried out, including grinding and polishing the surface of the bollard to achieve the surface roughness and dimensional accuracy required by the design. Precise machining is performed on the installation holes, connection parts, etc., to ensure the fitting accuracy with components such as anchor rods and nuts.

● Surface Treatment: Surface treatment methods such as hot - dip galvanizing and spraying anti - corrosion paint are used. Hot - dip galvanizing can form a dense zinc layer on the surface of the bollard, effectively preventing the corrosion of cast iron by seawater, air, etc. Spraying anti - corrosion paint can further improve its corrosion resistance. Also, different colors of paint can be selected according to needs, serving the functions of aesthetics and identification.

● Quality Inspection: Visual inspection is carried out to check whether there are defects such as cracks, sand holes, and blowholes on the surface of the bollard, and whether the surface roughness and dimensions meet the design requirements. Non - destructive testing methods such as ultrasonic testing and radiographic testing are used to detect internal defects such as shrinkage porosity and inclusions. Mechanical property tests, such as tensile tests and impact tests, are conducted on the bollard to ensure that its performance indicators such as strength and toughness meet the usage requirements.

Design and Structure

In port facilities, mooring bollards are crucial equipment for ensuring the safe berthing and mooring of vessels. Today, we will introduce to you in detail a T - shaped cast - iron mooring bollard with outstanding performance. Its unique design and structure can better meet the needs of modern port operations.

Design Concept: The Integration of Safety and Efficiency

The design of this T-shaped cast iron mooring bollard is closely centered around the safety and efficiency of ship mooring operations. From the ship's berthing, docking, to operations such as shifting berths and turning around, the mooring bollard needs to withstand various complex forces. Its design fully takes into account different ship types, tonnages, and dock operating environments to ensure reliable mooring support for ships under all working conditions.

For example, in the design of the height, diameter, and the size of the T-shaped structure of the mooring bollard, precise calculations and simulation analyses have been carried out. A reasonable height can not only ensure that the ship's mooring ropes can be easily tied, but also prevent the ropes from being easily washed off by the waves in bad weather. Appropriate diameter and structural dimensions endow the mooring bollard with sufficient strength and stability to withstand the tension and impact force when the ship is moored.

Structural Composition: Guarantee of Durability

1. Shell: It is made of high-quality cast iron, which has good abrasion resistance, corrosion resistance, and high strength. The properties of cast iron enable it to be used stably for a long time in the humid and high-salt port environment, and it is not easy to rust or be damaged. The T-shaped design of the shell increases the structural stability, allowing it to remain firm when subjected to lateral forces.

2. Anchor Bolts: Anchor bolts are important components connecting the bollard to the dock foundation. They are usually made of high-strength steel. These bolts penetrate deep into the dock foundation and are closely matched with the anchor plate through nuts and washers, firmly fixing the bollard to the dock structure. The number and arrangement of anchor bolts are reasonably designed according to the specifications of the bollard and the bearing capacity of the dock to ensure that the bollard will not displace or loosen under various loading conditions.

3. Nuts, Washers, and Anchor Plates: These accessories work together to evenly distribute the tension of the anchor bolts, preventing damage to the dock foundation and the bollard during the tightening process. The nuts are made of high-strength materials and have good anti-loosening performance. Washers can increase the contact area and reduce stress concentration. The anchor plate further expands the force-bearing area, enhancing the connection reliability between the bollard and the dock foundation.

4. Core Filler: The core filler is filled inside the shell, playing a role in buffering and enhancing the structural integrity. Materials with good elasticity and compressive performance, such as rubber or special fillers, are generally selected. When the ship's mooring cable generates an impact force, the core filler can absorb part of the energy, reducing damage to the bollard and the dock structure.
