Pipe pile is an important material used in construction engineering, which is widely used in the basic construction of bridges, high-rise buildings, docks and other projects. Due to the promotion of urbanization and the increase of infrastructure construction, the demand for pipe piles has greatly increased, which has led to the rapid development of pipe pile industry. At the same time, the production and processing of pipe piles need high technical requirements and professional knowledge, including material selection, processing technology and quality control. These high technical requirements make workers engaged in pipe pile production need to receive professional training and have relevant skills, so their wages are relatively high.
