It has the characteristics of easy installation, reliable connection, corrosion resistance, no gas blocking, good flexibility, long service life, and can be bent arbitrarily without deformation and no gas blocking. During the construction of gas pipeline, the installation is difficult, time-consuming, and labor-intensive.
