Stainless steel 0Cr13 tortoise shell net , 410S tortoise shell net
Descriptions :
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.
Different Types of Hexmesh:
- L type mesh – this style has lance tabs protruding from the walls of the hexagonal cell to act as anchorage for the refractory.
- H type mesh – instead of lance tabs, holes are punched through the walls of the hexmetal cell. Refractory can then flow through these holes to achieve a bond from one cell to another.
- Punch tabs
- Hex, C & S-Bars

Applicaions :
- Tortoise Shell Mesh has gotten extensive application in chemical industry, petroleum, power generation, etc. Tortoise Shell Mesh is welded on cyclone dust collector or on the inside wall of the cylinder, poured refractory material. it is a hexagonal hole mesh, with bar steel pressed and punched, three are small holes in every border for refractory material inter flowing between the holes. The refractory material does not fall off to blockading the discharge hole.
- Tortoise shell net is widely used in large device in petroleum chemical industry, especially the main part for equipment of catalyst structure, it can enhance the lining's quality in abrasion resistance and strength, wear-resisting by using tortoise-shell net. General part use carbon steel (A3F) tortoise-shell net for reinforcement, such as reactor and a secondary cyclone separator and u-shaped tube regenerators; High temperature parts use alloy (1Cr13) tortoise-shell net for reinforcement, for example regenerators and a secondary cyclone separator place.
