Nozzle plug
Plugs, also known as pipe caps, caps, pipe caps, and bulkheads, are pipe fittings that are installed on the external threads of the pipe end to cover the pipe. Plugs are used to seal pipelines and have the same function as pipe plugs. They can be screwed directly on the pipe and do not require other pipe fittings. The plug includes the design of convex plug, cone shell, reducing section, flat cover and tightening port. Lanzhong Electromechanical's nozzle plugs are mainly designed for various fire sprinklers, and their purpose is to test the sealing performance.

Types of nozzle plugs:
Sprinkler plugs are used to test the sealing performance of fire sprinkler heads. Different types of fire sprinkler plugs have different specifications and sizes. Lanzhong Electromechanical's plugs are generally customized for its own customers. Non-Lanzhong customers can also purchase them if the thread size of the nozzle they use is compatible with its plugs. The following are the types of Lanzhong electromechanical nozzle plugs:
1. Water mist open nozzle plug
2. Water mist closed nozzle plug
3. Perfluorohexanone gas nozzle plug
4. High-speed water mist nozzle plug
5. Low pressure atomizing nozzle plug
Nozzle plug price:
Lanzhong Mechanical and Electrical's various fire sprinklers have some conventional models, so the specifications and models of plugs also have some conventional models. Whether they are their own customers or non-Lazhong customers, as long as the plugs can match the sprinklers, they can purchase them. But if it is an unconventional type of nozzle, then a plug with matching specifications and sizes needs to be customized. The following is the reference price of regular model plugs of Lanzhong Electromechanical:
Unit price: 6 yuan/piece
Nozzle plug customization:
The nozzle plug is used on the fire sprinkler head to test the sealing, so the thread size must match the nozzle. If the customer is using an unconventional type of fire sprinkler nozzle, then if a plug is required, it must be customized separately. Lanzhong electromechanical plug customization is only for its own customers. Non-Lanzhong customers can only purchase conventional types of plugs. The following are some parameters that need to be provided for plug customization.

Nozzle plug manufacturing method:
1. Small plug: integrally formed;
2. Large and medium-sized plugs: spliced first and then formed - the most commonly used plugs, and the requirements in the standard are mainly aimed at them;
3. Extra large plugs: Due to transportation and opening requirements, they are first formed into separate pieces and then assembled and welded together.
Common types of nozzle plugs:
According to the different threads, they are divided into: metric, imperial, and American.
According to different shapes, they are divided into: internal hexagonal plugs, external hexagonal plugs, tapered thread plugs, square plugs
According to different materials, they are divided into: plastic plugs, cold-beaten plugs, 45# plugs, stainless steel plugs, copper plugs
