Piling Pipe Size

Piling pipe is a building material composed of seamless steel pipe, ERW steel pipe or SSAW steel pipe, which is widely used in various engineering projects. Piling pipe comes in a variety of sizes and can support loads from 50 to 500 kilopounds. The diameter ranges from a few inches to a few feet, and the common size ranges from 8 inches in diameter to more than 50 inches in diameter. If you want to buy used piling pipe, the most choices are in the diameter range of 18 inches to 28 inches. Piling pipes can be connected together to form pile structures hundreds of feet long. In offshore and inland alluvial plain areas, the 50 to 60-meter thick soft soil layer under the upper load cannot be directly used as the bearing layer. The low compressive bearing layer is often deeper, and the piling pipe structure is usually used because the pile hammer exerts a greater impact force on it. At this time, it is more appropriate to use piling pipe to strengthen the foundation than to use conventional reinforced concrete piles and prestressed concrete piles.

What is the standard length of piling pipe?

The standard length of piling pipe is usually 6 meters, 9 meters or 12 meters, which can meet the needs of most construction and engineering projects. However, in some special cases, other lengths of piling pipe can be customized according to specific needs. When choosing the length of piling pipe, it should be based on the actual project requirements and geological conditions. If the underground soil layer is deep or there are strong bearing requirements, it may be necessary to choose a longer length of piling pipe to meet the design requirements. In addition, the limitations of construction equipment and processes need to be considered during construction to ensure that the piling pipe can be installed and driven smoothly.

As a basic material with stable structure and strong bearing capacity, pile pipe is suitable for various construction projects, especially in projects that need to bear heavy loads and complex geological conditions. According to different construction requirements and project designs, pile pipes can be selected in different specifications and materials to ensure the safety and stability of the project. The following will introduce several commonly used specifications:

SSAW steel pipe for piles

SSAW steel pipe for piles is made by rolling steel plates into cylinders and then spiral welding. It has a large diameter and thick wall, and is suitable for projects that require large load-bearing capacity and deep piling depth. Its main specifications include:

Pipe diameter range: ranging from 325mm to 2400mm.

Wall thickness range: generally between 8mm and 60mm.

Length range: usually 6m to 12m, which can be customized according to specific construction needs.

Spiral welded piling pipes are particularly common in bridge construction. They can withstand the horizontal and vertical loads of large bridge structures, ensuring the stability of bridges and long-term safety. Its high strength and superior deformation capacity make it widely recognized for its application in complex geological conditions.

Pile foundation grouting pipe

Pile foundation grouting pipe is mainly used to strengthen pile foundation, and improve the bearing capacity and stability of pile foundation by injecting slurry into the pipe. Common materials include galvanized steel pipe and plastic pipe, and its main specifications include:

Diameter range: ranging from 20mm to 50mm.

Wall thickness range: generally between 0.5mm and 2.5mm, which varies according to different materials.

Length range: usually 2m to 5m, the specific length depends on the depth of pile foundation and construction requirements.

Pile foundation grouting pipe is suitable for building foundation projects under various geological conditions, such as soft soil or occasions where the bearing capacity of pile foundation needs to be enhanced. Through effective grouting operations, the stability of pile foundation can be improved and the service life of the structure can be extended.

Pile foundation ultrasonic inspection tube

Pile foundation ultrasonic inspection tube is used for quality assessment and non-destructive testing of pile foundation to ensure its integrity and safety. According to different testing needs, ultrasonic inspection tubes are divided into short tubes, standard tubes and long tubes, and their main specifications include:

Short tube length: generally 3m to 5m.

Standard tube length: usually 6m or 9m.

Long tube length: generally 12m or 15m.

These pipes use ultrasonic technology to conduct in-depth inspection of pile foundations, evaluate their internal structure and quality status, and provide important reference for the subsequent construction and use of the project.

Types of Piling Pipes and Their Characteristics

There are many types of piling pipes, each with its own unique characteristics and advantages. Common types include open-end piles, closed-end piles, baseplate piling pipes, and piling pipes with rock bases. Different types of piling pipes are suitable for different engineering needs. For example, open-end piles are suitable for penetrating soft soil or soil with high water content, allowing water to enter the pile body to form a hydraulic lock, thereby providing additional support. Closed-end piles have a cap on the top to prevent water from entering the pile body, which is suitable for situations where water may cause soil instability. Baseplate piling pipes have a flat plate at the bottom to provide additional load-bearing capacity and are suitable for structures such as high-rise buildings that require a lot of support. Piling pipes with rock bases have a steel base at the bottom and are filled with rocks or other materials to provide additional support, which is suitable for loose or soft soil conditions.

The installation process of piled pipe

The installation process of piled pipe requires the use of a pile driver to drive the pile into the ground. This process requires careful planning and execution to ensure that the pile will be properly seated and support the required load. Before the pile is driven, the soil conditions and load requirements must be assessed to determine the appropriate length and diameter of the pile. The soil should be strong enough to support the pile and resist lateral and vertical forces. The impact force of the pile driver enables the pile to penetrate the soil and reach the required depth. Once the pile is in place, the ground is compacted to provide additional support.

Advantages of Using Piling Pipe

There are many advantages to using piling pipe in construction projects. Piling pipe has the strength and durability to withstand heavy loads and harsh conditions, making it ideal for building structures such as bridges, ports, and offshore facilities. In addition, the versatility of piling pipe allows it to be customized to specific requirements, making it suitable for a variety of construction projects. They are also corrosion-resistant, making them ideal for structures exposed to harsh environments. While the initial cost of piling pipe may be higher than other materials, its strength and durability make it a cost-effective choice in the long run.

Material properties of pile pipes

Pile pipes are round steel pipes that play an important role as foundation materials for civil engineering and construction due to their high strength and uniform quality. The increasing number of large-scale construction projects on soft soil foundations or in coastal areas, as well as marine civil engineering projects, has made the seismic resistance of buildings an even more important issue. Piling pipes are able to meet these requirements and can serve as highly reliable foundation materials with their high strength and seismic resistance.

Installation methods of pile pipes

Pile pipes are installed in two main ways: pile driving and bored piles. Pile driving is a technique that uses a pile driver to hammer piles into the ground, commonly used in construction projects such as bridges and houses. Piling pipes can be driven into the ground through soil, sand or rock, and the force of the hammer's blows drives the pile into the ground to a depth that depends on the size of the pile and the type of soil. In some cases, it may be necessary to drive the pile into bedrock. Piling is an effective way to install piles in a short period of time, especially when traditional excavation methods are not feasible or too costly.

Bored piles are a construction method in which pile pipes are installed underground. Pile pipes are made of steel and are usually larger in diameter. There are three types of bored piles: end bearing piles, friction piles, and compacted piles. Bored piles are mainly used to support the foundation of buildings or other structures. They can also be used to stabilize the soil or sand below the foundation. In some cases, they can also be used to protect the foundation from water damage. If properly installed, bored piles can provide a solid foundation for any building or structure.

Which type of steel pipe is most commonly used for pile pipes?

SSAW steel pipes made of carbon steel plates are most commonly used for pile pipes. They are mainly used in offshore water environments with deep water, waves, currents, and large ship impact forces. Pile pipes have a series of advantages such as high strength and strong bending resistance; good elasticity, can absorb large deformation, reduce the impact of ships on dock buildings; easy construction, can speed up the construction progress of dock facilities.

In summary, pile pipes, as a high-strength, durable and versatile building material, play a vital role in modern engineering. Whether it is a bridge, port or offshore facility, pile pipes can provide reliable foundation support. By choosing the right type and size, combined with professional installation technology, pile pipes can ensure the stability and safety of building structures under various environmental conditions.
