FAQ

Q2: What`s the lead time for my order?

A2: It depends on customers’ requirements and our production schedule. And usually we need 30-60 days for refractory bricks,10-25 days for unshaped refractory materials and 10-20 days for ceramic fiber blankets.

Q3: Can you offer Door-to-Door delivery?

A3: Yes, but only for some countries such us U.S., UAE, Saudi Arabia, Iran, and Russia, etc.

Q:Are insulating fire bricks resistant to high-velocity gas flow erosion?: Yes, insulating fire bricks are generally resistant to high-velocity gas flow erosion. These bricks are designed to withstand high temperatures and are made from materials that can withstand the erosive effects of gases flowing at high velocities. However, the resistance may vary depending on the specific composition and quality of the fire bricks.

Q:Can insulating fire bricks be used in outdoor fire pits?: Yes, insulating fire bricks can be used in outdoor fire pits. Insulating fire bricks are designed to withstand high temperatures, making them suitable for use in fire pits. They are made from materials that are resistant to heat, such as ceramic fibers or refractory materials, which helps to retain the heat within the fire pit. Additionally, insulating fire bricks are lightweight and easy to install, making them a convenient choice for outdoor fire pits. However, it is important to note that insulating fire bricks may not be as durable as regular fire bricks, so they may require more frequent replacement if exposed to extreme temperatures or harsh weather conditions.

Q:Are insulating fire bricks resistant to moisture or water damage?: Yes, insulating fire bricks are resistant to moisture or water damage. They are designed to withstand high temperatures and do not absorb water, making them a suitable choice for applications where moisture or water exposure is a concern.

Q:Can insulating fire bricks be used in the construction of high-temperature reactors?: Yes, insulating fire bricks can be used in the construction of high-temperature reactors. These bricks are designed to withstand and retain high temperatures, making them suitable for use in applications such as high-temperature reactors where heat insulation is required.

Q:Can insulating fire bricks be used in high-temperature insulation panels?: Yes, insulating fire bricks can be used in high-temperature insulation panels. Insulating fire bricks are designed to withstand and retain heat, making them an ideal choice for applications that require high-temperature insulation.

Q:Can insulating fire bricks reduce heating or cooling costs?: Yes, insulating fire bricks can help reduce heating or cooling costs. These bricks are designed to have low thermal conductivity, which means they prevent heat transfer between the indoor and outdoor environment. By using insulating fire bricks to build or line the walls of a building, less heat is lost during the colder months and less heat is gained during the hotter months. This can result in lower energy consumption and reduced heating or cooling expenses.

Q:Can insulating fire bricks be used in foundries?: Yes, insulating fire bricks can be used in foundries. They are commonly used as lining materials for various high-temperature applications, including foundries. Insulating fire bricks provide excellent thermal insulation, reducing heat loss and improving energy efficiency in the foundry process. Additionally, they have good resistance to thermal shock and can withstand the extreme temperatures and harsh conditions often found in foundry environments.

Q:Can insulating fire bricks be used for insulation in sewage treatment plants?: Insulating fire bricks are capable of being utilized for insulation purposes in sewage treatment plants. Specifically designed to endure elevated temperatures and deliver exceptional insulation, these bricks prove to be suitable for deployment in environments characterized by heat and moisture, such as sewage treatment plants. With their low thermal conductivity, they aid in diminishing heat loss and enhancing energy efficiency throughout the treatment procedure. Furthermore, their resistance to chemicals and moisture renders them ideal for enduring the corrosive surroundings typically encountered in sewage treatment plants. Consequently, the usage of insulating fire bricks effectively ensures insulation in sewage treatment plants, thereby aiding in the preservation of optimal operating temperatures and the enhancement of overall efficiency.

Q:Can insulating fire bricks be used in oil refineries?: Yes, insulating fire bricks can be used in oil refineries. These bricks are designed to withstand high temperatures and provide excellent insulation, making them suitable for various industrial applications, including oil refineries. They help to reduce heat loss, improve energy efficiency, and protect the surrounding equipment and structures from extreme heat.

Q:Are insulating fire bricks resistant to mold or mildew?: Insulating fire bricks do not have resistance to mold or mildew. These bricks are made to withstand high temperatures and provide insulation, but they do not naturally prevent mold or mildew growth. If exposed to moisture or dampness, mold and mildew can still develop on the surface of these bricks. To avoid mold or mildew, it is crucial to keep the bricks dry and well-ventilated. Regular cleaning and maintenance can also be effective in preventing mold or mildew growth on the bricks.
