After the deep foundation pit is backfilled, the steel sheet pile shall be removed to facilitate repeated use. Before pulling out the steel sheet piles, the sequence of pulling out methods, pile pulling conditions and soil holes should be studied carefully and scientifically.

Prestressed concrete pipe piles can be divided into post-tensioned pre-stressed pipe piles and pre-tensioned pre-stressed pipe piles.

pipe spools are used in almost all industrial applications because they are very dexterous.

The medium in the boiler pressure vessel is generally a certain pressure gas, liquefied gas or high-temperature liquid. Once the pressure-bearing part ruptures, the medium releases pressure and expands or instant

When traditional reinforced concrete and prestressed concrete piles are difficult to adapt, steel pipe piles are often used to strengthen the foundation.

There are several stages in the production process of the piping spools. All stages are implemented for specific goals, and the arrangement between stages is very large.
