GWH fire sleeve is widely used in petrochemical industry. Many raw materials, semi-finished products and finished products in the petrochemical production process are flammable and explosive substances, which increases the risk of fire and explosion accidents. Therefore, strengthen the overall fire prevention and control awareness of petrochemical enterprises, start from the production source, and gradually do a good job in fire prevention and control in the production process, so as to promote the safe and stable development of petrochemical production It has become extremely important. Beijing Great Pack Materials Co., Ltd. analyzes the fire risk of petrochemical enterprises, and according to the actual situation, applies the high-temperature fire sleeve in the petrochemical field, so as to maximize the safety and effectiveness of fire and explosion prevention work. Some chemical industry has a lot of strong acid and alkali production environment. The internal pipelines are protected by high temperature fire sleeve to prevent corrosion damage, and can effectively ensure the safety of workers.
