Disadvantages of spiral welded pipe

Analysis of disadvantages of spiral welded pipe (SSAW):

1. Low intensity
The relatively low strength of spiral welded pipe is one of its main disadvantages. Although some progress has been made in optimizing design and material selection for spiral welded pipe, its strength is still lower compared with other pipe products.

2. The connector is easily damaged

Spiral welded pipes usually require long-distance welding. Once the quality of the joints is not good, problems such as cracking and water leakage are prone to occur, and repairs are difficult. The pipes need to be dismantled for repairs. This is another disadvantage of spiral welded pipes.

3. Susceptible to corrosion

Spiral welded pipes are easily affected by environmental factors, such as organic matter, acid and alkali and other substances, which can cause surface corrosion and thus affect their overall performance and life. Therefore, when using spiral welded pipes, it is necessary to consider its use environment and take corresponding anti-corrosion measures.

4. High manufacturing technology requirements
The manufacturing process of spiral welded pipes is relatively complex and requires the control of multiple key parameters, such as welding temperature, welding speed, current intensity, etc. It is also necessary to pay attention to environmental temperature, humidity, pressure and other factors. Therefore, the requirements for manufacturing spiral welded pipes are relatively high and require relevant equipment and technical personnel.

5. Not suitable for use in high-pressure situations
Due to the low strength of the spiral welded pipe, its use in high-pressure situations is limited, because the pressure inside the pipe under high pressure will be very large, which can easily lead to problems such as pipe rupture and water leakage. Therefore, for use in high-pressure situations, other more suitable pipeline products need to be considered.

In summary, although spiral welded pipes are widely used in construction, water supply and drainage, oil and gas transportation and other fields, they also have some shortcomings. In actual use, it is necessary to select appropriate pipeline products according to different situations and requirements, and strengthen management and inspection during installation and maintenance to ensure their normal use and extend their life.
