Welded Threaded Pipe Fittings

Welded Threaded Pipe Fittings are widely used in multiple fields due to their combination of welding firmness and threaded connection convenience.The following are some common application scenarios:

Building water supply and drainage system

Residential and commercial buildings:In the water supply and drainage pipeline systems of residential,office,shopping malls and other buildings,welded threaded fittings are used to connect water pipes and achieve water supply and discharge.For example,the connection of hot and cold water pipes in bathrooms and kitchens,as well as the connection of rainwater and sewage pipes in buildings,often uses different specifications of welded threaded fittings such as DN15-DN150,such as elbows,tees,and crosses,to meet the requirements of pipeline systems for turning and branching.

Municipal water supply and drainage:Welded threaded pipe fittings are also used in urban municipal water supply and drainage engineering.In urban water supply networks,welded threaded fittings are used to connect small branch pipelines or household pipelines.In sewage treatment plants,pipelines are used to connect treatment equipment to ensure smooth transportation of sewage between various treatment stages.

HVAC system

Heating system:In a centralized hot water heating system,welded threaded fittings are used to connect heating pipelines.Carbon steel welded threaded fittings are commonly used for heating pipelines from thermal stations to various buildings,as well as connecting pipes for radiators inside buildings.These fittings can withstand a certain temperature and pressure,ensuring the circulation of hot water and achieving indoor heating.

Air conditioning system:Welded threaded fittings play an important role in the chilled water and cooling water pipeline systems of air conditioning.For example,the pipeline connection between the air conditioning unit,fan coil unit,and cooling tower usually uses various specifications of welded threaded fittings to achieve the circulation of refrigerant or cooling water,ensuring the normal operation of the air conditioning system.

Industrial piping system

Chemical industry:In chemical production,many corrosive media need to be transported through pipelines.For some situations where the corrosiveness is relatively weak and the pressure and temperature requirements are not particularly high,corrosion-resistant alloy steel or stainless steel welded threaded fittings will be used.For example,in some small-scale chemical experimental devices or auxiliary production processes,pipelines are used to connect acid,alkali and other solutions.

Oil and gas industry:Welded threaded fittings are also used in the extraction,transportation,and processing of oil and gas.For some small-diameter pipeline connections in wellhead equipment,as well as some instrument air pipelines and heat tracing pipelines in natural gas processing plants,welded threaded fittings will be used for easy installation and maintenance,ensuring the sealing and reliability of the pipeline system.

Power industry:Welded threaded fittings are used in various auxiliary piping systems in power plants.For example,in the desalination water system and industrial water system of thermal power plants,welded threaded fittings are often used to connect pipelines such as water pumps,valves,and filters to ensure the stable operation of the pipeline system and provide support for the normal operation of the generator set.

Fire protection system

Building fire protection:Welded threaded fittings are an important component of the fire water supply system in buildings.The pipeline connections in fire hydrant systems and automatic sprinkler systems usually use welded threaded fittings that meet fire safety standards.Welded threaded elbows and tees,such as DN65-DN150,are used to connect fire risers,branch pipes,fire hydrants,nozzles,and other equipment to ensure rapid and effective water supply and fire extinguishing in the event of a fire.

Gas pipeline system

Urban gas:In urban gas transmission and distribution systems,welded threaded fittings are used for connecting some household pipelines or small gas facilities.The connecting pipes from gas meters to gas appliances(such as gas stoves,gas water heaters,etc.)often use stainless steel or copper welded threaded fittings to ensure the safety and stability of gas transmission.
