FAQ

How can the immersed pipe pile put steel cage into the steel pipe? Which expert to answer?

Cast-in-place pile for pile machine in place, hammer (vibration), on the edge of immersed tube material, hammer (vibration) side of extubation, and continue pouring concrete, steel cage, continue pouring concrete and extubation to pile.

There are several types of steel pipe connections commonly used in fire sprinkler systems, including threaded connections, grooved connections, and welded connections. Threaded connections involve screwing the pipes together using tapered threads and are commonly used for smaller pipe sizes. Grooved connections use a coupling and gasket system to join the pipes, creating a secure and flexible connection. Welded connections involve permanently joining the pipes together using heat and are typically used for larger pipe sizes or in situations where maximum strength is required.

Steel pipes are commonly used in the pulp and paper industry for various applications including transporting water, steam, and chemicals throughout the manufacturing process. They are also used for conveying pulp and paper products, as well as for supporting structures such as boiler systems and storage tanks.

Steel pipes are typically tested for leaks using various methods such as hydrostatic testing, pneumatic testing, or advanced technologies like ultrasonic testing. In hydrostatic testing, the pipe is filled with water or another liquid, and pressure is applied to check for any leaks. Pneumatic testing involves using compressed air or gas to pressurize the pipe and identify potential leaks. Ultrasonic testing employs high-frequency sound waves to detect any leaks or flaws in the steel pipes. These testing methods ensure the integrity and quality of steel pipes before they are put into use.

When can I use the PVC pipe and when to use the galvanized pipe?

Galvanized pipes are generally used outside the drying environment or building blocks, and PVC is mainly used for pre embedding in walls or humid environments. If in the ceiling ceiling, below the roof, you need to use galvanized pipe, in the floor below, on the ground you need to use PVC.

Stainless steel tube, also known as why tube?

The longitudinal section can be divided into equal section tube and variable cross section tubeThe variable section tube has a conical tube, a stepped tube and a periodically cross section pipe, etc.

Steel pipes have several advantages over other materials such as PVC or copper. Firstly, steel pipes are incredibly durable and strong, making them suitable for heavy-duty applications and high-pressure environments. Additionally, steel pipes have a longer lifespan compared to PVC or copper, as they are less prone to cracking, corrosion, or degradation. Steel pipes also provide better fire resistance and are more resistant to extreme temperatures. However, steel pipes can be more expensive and require professional installation due to their weight and rigidity. PVC pipes, on the other hand, are lightweight, affordable, and easy to install, but they may not be as durable or suitable for certain applications. Copper pipes offer excellent corrosion resistance and are commonly used for water supply systems, but they can be more expensive and require skilled labor to install. Ultimately, the choice between steel, PVC, or copper pipes depends on the specific requirements of the project and the desired balance of cost, durability, and performance.

There are several methods of measuring the thickness of steel pipes. One common method is using ultrasonic thickness gauges, which send high-frequency sound waves through the pipe and measure the time it takes for the waves to bounce back. Another method is through magnetic induction, which uses a magnetic field to determine the thickness based on the changes in the field caused by the pipe's thickness. Additionally, there are mechanical methods such as using calipers or micrometers to directly measure the thickness of the pipe.
