Types of Piling Pipe for Various Soil Conditions and Structural Requirements
When it comes to piling methods, different soil conditions and structural requirements call for specific types of piling pipes. Understanding these variations is crucial to ensure the effectiveness and stability of the foundation. In this article, we will explore some of the most prevalent types of piling pipes used in construction projects.
Unplugged Open-Ended Piling Pipe
Unplugged open-ended piling pipes are characterized by their fully open ends. Once installed, the ground level inside and outside the pipe is expected to be at the same level. These pipes rely primarily on friction to distribute their load to the surrounding soil. The friction between the pipe and the soil provides the necessary support and stability.
Plugged Open-Ended Piling Pipe
Plugged open-ended piling pipes, on the other hand, have a stopper or plug at the bottom end of the pipe. This design results in the soil inside the pipe being slightly less dense than the soil outside the pipe. The density difference creates additional friction, enhancing the load-bearing capacity of the pile.
Bottom Plate Piling Pipe
Bottom plate piling pipes are one of the commonly used types of plugged piles. In this case, a steel plate is welded to the bottom end of the pipe. The purpose of the plate is to compress the soil and increase friction, preventing sliding and enhancing stability. These types of piles are often used in rocky terrains where a thin layer of soil separates the rock and the pile.
Steel Pipe with Rock Shoe
Steel pipes with rock shoes are another type of plugged piles. Similar to bottom plate piles, rock shoes aim to increase friction and prevent sliding. However, they are specifically used when the pile comes into direct contact with a rock surface. The rock shoe must be capable of supporting the entire load and preventing it from sliding down the rocky surface.
Franki Piling Pipe
Franki piling pipes are designed to provide long-lasting stability. These piles are filled with a moist concrete infill, which significantly increases their load-bearing capacity. Franki piles can withstand greater impact during the driving process compared to other types of piles. They are known for their durability and are often used in projects where longevity is a priority.
Choosing the right type of piling pipe is crucial for ensuring the stability and longevity of a structure’s foundation. Unplugged open-ended piles rely on friction, while plugged piles with bottom plates or rock shoes enhance friction and prevent sliding. Franki piles, filled with a concrete infill, offer exceptional durability. By understanding the characteristics and applications of each type of piling pipe, construction professionals can make informed decisions and ensure the success of their projects.
ERW (Electric Resistance Welded) pipe piling is a type of steel pipe that is commonly used in construction and foundation applications, such as in the building of bridges, wharves, and other structures. ERW pipe piling is created by using a process in which a flat steel strip is rolled into a tube shape, and then the edges are heated and welded together using an electric current. ERW pipe piling has a number of advantages over other types of piling, including: Cost-effective: ERW pipe piling is generally less expensive than other types of piling, such as seamless pipe piling. High strength: ERW pipe piling is highly resistant to bending, making it a strong and durable option for foundation applications. Customizable: ERW pipe piling can be manufactured to meet specific size and length requirements, making it highly customizable and adaptable to different project needs.ERW Pipe Piling is available in a range of sizes and thicknesses, and can be produced in lengths of up to 100 feet or more. It is typically made from carbon steel or alloy steel, and can be coated with a layer of protective material to help prevent corrosion and extend the lifespan of the pipe. Versatile: ERW pipe Read more
The use of pipe piles in foundation construction has been a popular choice for many years. Pipe piles are used to transfer the load of a structure to a deeper, more stable layer of soil or rock.
Benefits of Pipe Trusses The use of pipe trusses in construction offers several notable advantages: Strength and Load-bearing Capacity: Pipe trusses are renowned for their high strength-to-weight ratio. The interconnected pipes distribute loads evenly, resulting in a sturdy and reliable structure. This allows for the construction of large spans without the need for excessive support columns or beams.
The standard for fluid-conveying seamless pipes depends on the country or region you are in, as well as the specific application. However, some widely used international standards for fluid-conveying seamless pipes are: ASTM A106: This is a standard specification for seamless carbon steel pipes for high-temperature service in the United States. It is commonly used in power plants, refineries, and other industrial applications where high temperatures and pressures are present. It covers pipes in grades A, B, and C, with varying mechanical properties depending on the grade. API 5L: This is a standard specification for line pipes used in the oil and gas industry. It covers seamless and welded steel pipes for pipeline transportation systems, including pipes for conveying gas, water, and oil. API 5L pipes are available in various grades, such as X42, X52, X60, and X65, depending on the material properties and application requirements. ASTM A53: This is a standard specification for seamless and welded black and hot-dipped galvanized steel pipes used in various industries, including fluid-conveying applications. It covers pipes in two grades, A and B, with different mechanical properties and intended uses. DIN 2448 / EN 10216: These are European standards for seamless steel pipes used in fluid-conveying applications, including water, gas, and other fluids. Read more
Fluid-conveying seamless pipes are designed to resist various types of corrosion depending on the material used and the specific application. Some of the most common types of corrosion that these pipes are designed to resist include: Uniform corrosion: This is the most common type of corrosion, where the entire surface of the pipe corrodes uniformly. To resist this type of corrosion, pipes are often made of corrosion-resistant materials, such as stainless steel or lined with protective coatings. Galvanic corrosion: This occurs when two dissimilar metals are in contact with each other in the presence of an electrolyte, leading to the corrosion of the more active metal. To prevent galvanic corrosion, pipes can be made of similar metals, or they can be isolated from each other using insulating materials or coatings. Pitting corrosion: Pitting is a localized form of corrosion that occurs when small areas on the pipe's surface become more susceptible to attack, leading to the formation of small pits. This type of corrosion can be prevented by using materials with high pitting resistance, such as stainless steel alloys with added molybdenum, or by applying protective coatings. Crevice corrosion: Crevice corrosion occurs in narrow spaces or gaps between two surfaces, such Read more
