A105N Hex Head Plug
The overall shape of the A105N hex head plug is a combination of a hexagonal head and a plug body. The hexagonal head design is convenient for operation with tools such as wrenches, and can provide better torque transmission, so that the tube plug can be tightened or loosened.

hex head plugs made of carbon steel have high strength and good wear resistance, and are suitable for some industrial pipeline systems with high strength requirements. For example, in the steam transmission pipelines of large factories, carbon steel hex head plugs can withstand high pressures to prevent steam leakage.
Carbon steel hex head plugs are widely used in various industrial fields such as petrochemicals, power plants, natural gas, boilers, equipment, pumps and valves. In these fields, the stability and safety of the pipeline system are crucial, and carbon steel hex head plugs have become indispensable pipeline connectors with their excellent performance and reliable quality.

Application fields of A105N hex Head plug
Industrial field
In the petrochemical industry, a large number of pipelines are used to transport crude oil, natural gas, various chemical raw materials, etc. Carbon steel hexagonal pipe plugs can be used to plug spare pipeline interfaces, sampling ports, etc. For example, in the crude oil pipeline network of the refinery, there are many branch pipelines that do not need to be used in certain circumstances. Carbon steel hexagonal pipe plugs can be installed at the ends of these pipelines to prevent crude oil leakage, and can be easily disassembled for pipeline expansion or modification when necessary.
In the power industry, it is used to plug steam pipes and cooling water pipes in power plants. In thermal power plants, the steam pipeline system is very complex. During the maintenance, overhaul or partial modification of the pipeline, carbon steel hexagonal pipe plugs can temporarily plug unnecessary pipeline interfaces to ensure the safety and normal operation of the system.
Construction field
In the building water supply and drainage system, although the main pipeline material may be plastic, etc., carbon steel hexagonal pipe plugs may be used in some special parts or where they are connected to other metal parts. For example, in the basement fire water system of a building, if some reserved pipeline interfaces are temporarily unused, carbon steel hexagonal pipe plugs can be used to prevent groundwater or debris from entering the pipeline.
