High-temperature shells net hole or screen is like as the shell of a turtle, so called turtle shell mesh , tortoise shell net, tortoise shell mesh and tortoise mesh. The shape like hex , for used to petrochemical, power and cement industry , have petro-wire & steel hex metal , hex grid metal named. Tortoise shell nets have big mud claws, which is widely applied as fixing of lining of heat resistant material. The operation procedure of tortoise shell net is to tack up the mesh by welding to the inner wall of boiler or hot wind pipes, then to smear heat-resistant materials.
