Application of stainless steel hexmesh （hexmetal）

The stainless steel hexmesh（hexmetal）produced by Longen is mainly used in industrial lining reinforcement scenarios that require resistance to high temperature wear and corrosion due to its high temperature resistance, corrosion resistance, and high strength. Its core value lies in firmly grasping the refractory casting material through a hexagonal mesh structure, preventing the material from cracking and falling off under harsh working conditions, thereby extending the service life of the equipment.

Petrochemical industry: the core battlefield for high temperature resistance

This is the core application area of hexmesh（hexmetal）, mainly dealing with high temperature, high pressure, and catalyst erosion.

The main usage locations include key equipment in catalytic cracking units:

Cyclone separator: The inner lining of the first and second stage cyclone separators. This area needs to withstand extremely high gas flow rates and the impact of catalyst particles. Usually, high-temperature parts will use alloy materials such as 1Cr13 for the hexmesh（hexmetal）.

Reactor and regenerator: The internal temperature of the equipment is extremely high and accompanied by chemical corrosion. The hexmesh（hexmetal）can ensure that the lining material remains firmly attached under thermal expansion and contraction.

Flue and catalyst transport pipelines: The inner walls of these pipelines are subject to constant erosion by high-temperature dusty gases, making them a severely affected area for wear and tear。

Thermal power generation industry: responding to high-temperature coal powder erosion

In power plants, hexmesh（hexmetal） is mainly used to resist the continuous high-speed friction of coal powder and ash residue:

Coal powder conveying pipeline: This is the pipeline between the coal mill and the burner, where coal powder is transported by high-speed airflow, causing significant wear on the inner wall.

Circulating fluidized bed boiler: The combustion chamber and high-temperature cyclone separator of the boiler operate at high temperatures and experience severe material erosion.

The casing and air duct of the powder discharge machine: The high concentration coal powder flowing inside is highly susceptible to wear and tear.

Cement and steel industry: reinforced wear-resistant layer

The main challenges in these two industries come from the long-term wear of raw material particles and the erosion of high-temperature gases:

The cement industry is mainly used for:

Vertical mill system: including air outlet duct, upper, middle and lower shells, powder selector, feeding chute and other parts-

Air duct system: air ducts from the grate cooler to the electrostatic precipitator, tertiary air ducts (high temperature resistant), high temperature fan casing and pipelines.

Cyclone separator: a cyclone shell and inlet/outlet air duct used for separating materials.

The steel industry is mainly used for:

Material conveying system: conveying silos, hoppers, and pipelines for ore, raw coal, and coke.

Blast furnace system: blast furnace feed chute, furnace aggregate bin, etc.

Dust removal system: dust collector housing and various types of air ducts, fan housing.

How to choose the appropriate material

The hexmesh（hexmetal） produced by LONGEN^® can flexibly select materials according to working conditions, which is also a key reference for your application selection:

Typical high temperature (about 750 ℃)，Alloy materials such as 1Cr13 and 0Cr13，sevenHigh temperature zone of regenerator and cyclone separator in petrochemical plant

Generally high temperature (about 750 ℃), recommended materials: 1Cr13, 0Cr13 and other alloy materials, suitable for high-temperature areas of regenerators and cyclone separators in petrochemical plants.

Higher temperature and corrosion (about 800 ℃), recommended materials: 304, 316, 321 stainless steel materials, suitable for circulating fluidized bed boilers and pipeline linings that require anti-corrosion。

Ultra high temperature (1150 ℃), recommended material: 310S stainless steel material, suitable for special furnaces in extreme high temperature environments.
