basic information
**Features** ■ High strength even with wall thicknesses of 1.2t to 3.2t The structure of the lock is formed by overlapping the edges of elongated plates, creating a robust locking mechanism, which results in a thickness four times that of the material used. This lock is continuously formed in a spiral shape around the outer circumference of the pipe, significantly enhancing its strength. ■ Lightweight for easy piping work With high negative pressure strength, thinner wall thicknesses can be selected compared to conventional gas pipes. Therefore, it allows for greater lightweight design, making piping work easier. ■ Various joint methods available In addition to traditional butt welding and flange joints, easy joint connections can be selected according to the specific site requirements. ■ Low friction loss The inside of the pipe is smooth as there are no protruding lock parts, resulting in extremely low friction loss. ■ Prefabrication processing available Various prefabrication processes can be carried out to suit site conditions. ■ High roundness due to continuous forming Continuous forming with a dedicated automatic pipe-making machine results in extremely high roundness. *For more details, please refer to the related links or feel free to contact us.*
