Liner plates may act as a temporary or secondary liner to be lined by other materials.They also serve alone as the permanent or primary liner; as the conduit itself.Installation and assembly can be done entirely from inside a liner plate structure.Non-tunneling uses of steel liner plates include storage bins,surge tanks and small retaining walls.APPENDIX L PRELIMINARY STRUCTURES - AustinTexas.govSection 16 Steel Tunnel Liner Plates.Recommended minimum factors of safety Longitudinal Test Seam Strength 3 Pipe Wall Buckling 2 Installation Stiffness 1 ** Minimum stiffness for installation is selected based on job conditions and practical experience.Minimum handling stiffness is checked in these calculations but shouldBolted plate structures TubosiderBolted plate is curved steel sheets of varying,widths,lengths and thicknesses.These are bolted together to form a durable structure.Combinations of different sized plates mean that a vast range of profiles can be created.We also make structures in four different corrugations,so theres an economic option for any application.
Corrugated steel tunnel liner.Corrugated Liner Plate provides corrugations extending through the lapped longitudinal joint.When assembled,this liner functions as a corrugated pipe with continuous circumferential corrugations.The result is more effective corrugation performance for the highest stiffness and strength in the industry!
