GAS

In gas transmission, distribution, and usage systems, pipe fittings are core precision components that form the "lifeline of safety." Due to the flammable and explosive nature of the media they transport, gas pipe fittings, while fulfilling basic connection functions, prioritize "absolute sealing, robust durability, and safe control," adhering to extremely stringent standards in their design and application.

Firstly, in constructing transmission and distribution networks, pipe fittings are the foundation for ensuring system integrity and reliability. In outdoor municipal medium-pressure networks and residential low-pressure networks, gas pipelines safely traverse underground, change direction, and enter community buildings through specialized steel flanges, welded elbows, and tees. All connections must employ special sealing processes to ensure zero leakage. Insulating flanges are used to prevent electrochemical corrosion between pipelines, protecting the long-term safety of the network.

Secondly, in achieving precise control and safe isolation, pipe fittings are the system's key "safety valves." Various gas-specific valves (such as ball valves and plug valves) are core control components, installed before pressure regulating boxes, building entrances, and each household's meter, used for starting and stopping the gas supply, sectional maintenance, and emergency shut-off. The sleeve at the wall penetration point of the gas inlet pipe prevents damage to the pipeline due to building settlement and provides a sealed isolation.

Furthermore, during end-user connection and adaptation, pipe fittings ensure safe entry and compliant use. Indoors, threaded fittings (such as elbows, tees, and unions) connect the gas meter to the riser and safely to terminal devices such as gas stoves and water heaters. These fittings have precise thread specifications and stronger sealing performance, eliminating the risk of indoor leaks.

In summary, every pipe fitting in the gas system is a specially designed and rigorously tested "safety guardian." They not only construct the delivery channel but also form a multi-layered, inherently safe protection system through leak-free connections, precise pressure control, corrosion protection, and safe isolation. It is these seemingly insignificant pipe fittings that silently safeguard the safety of every inch of pipeline from the gas source to the stove, ensuring a stable and worry-free gas supply for both public and residential use.
