Welded Threaded Pipe Fittings

Welded Threaded Pipe Fittings combine the firmness of welding with the convenience of threaded connections,and there are several common types:

Bend type

45°welded threaded elbow

Features:It can achieve a 45°directional change in the pipeline.Compared to a 90°elbow,the turning is more gentle,which can reduce the resistance and pressure loss of fluid flow in the pipeline.

Application scenario:Commonly used for pipeline systems that require small angle turns,such as indoor ventilation ducts in buildings,when bypassing obstacles or changing the direction of air ducts;It is also applicable to some process pipelines in chemical production that require relatively gentle changes in fluid flow direction.

90°welded threaded elbow

Features:It realizes a 90°right angle turn of the pipeline and is one of the most commonly used types of elbows,which can enable the pipeline to achieve a vertical layout in space.

Application scenario:Widely used in water supply and drainage systems,such as connecting water pipes in bathrooms and kitchens,allowing water pipes to smoothly turn at corners of the wall;In industrial pipelines,it is used to connect vertical and horizontal pipelines and construct complex pipeline networks.

Three way type

Equal diameter welded threaded tee

Features:The three interfaces have the same diameter,which can evenly distribute the fluid in one pipeline to the other two pipelines,or collect the fluid in two pipelines into one pipeline.

Application scenario:In fire sprinkler systems,equal diameter tees can evenly distribute fire water from the main pipe to each branch pipe nozzle;In some simple fluid transport systems,it is used to branch or converge pipelines to ensure balanced flow.

Reducing welding thread tee

Features:The diameter of the main and branch pipes is different,and the connection and fluid distribution between pipes of different diameters can be realized according to actual needs,meeting the requirements of different flow rates and pressures.

Application scenario:In the water supply system,when the main pipe diameter is large and a smaller diameter branch pipe needs to be introduced to supply water to a specific area,a reducing tee is used;In chemical production,reducing tees are used for pipeline connections based on the fluid flow requirements of different process equipment.

Direct Head Class

Ordinary welding thread direct head

Features:Used to connect two pipes of the same diameter,extending the length of the pipes,with a simple structure and easy installation.

Application scenario:In long-distance water and gas pipeline laying,ordinary direct heads are often used to connect multiple pipelines in sequence to form a complete transmission line;In some equipment's inlet and outlet pipeline connections,direct heads can also be used for pipeline docking.

Reducing welding thread direct head

Features:Used to connect two pipes of different diameters,achieve the transition of pipe diameters,and ensure the continuity and sealing of the pipeline system.

Application scenario:In the connection of water pump inlet and outlet pipelines,when the diameter of the water pump interface is different from that of the pipeline,a direct reducer is used for connection;In the installation of pipelines in air conditioning refrigeration systems,direct fittings with reduced diameters are used to adapt according to the differences in interface diameters of different components.

Four way type

Welding thread four-way

Features:With four interfaces,it can achieve cross shaped branch connection of pipelines,allowing fluid to be distributed or collected in multiple directions,suitable for complex pipeline layouts.

Application scenario:In the ventilation and air conditioning duct system of large industrial plants,four-way fittings can be used to construct multi-directional airflow channels,achieving uniform distribution and circulation of air;In the water supply and drainage network of some large buildings,it is used for connecting and diverting pipes in multiple directions.

Other types

Welding threaded pipe cap

Features:Used to seal the end of a pipeline,preventing fluid leakage or external impurities from entering the pipeline,and protecting the pipeline system.

Application scenario:Installing pipe caps for protection during the debugging,maintenance,or temporary shutdown of pipeline systems;In industries such as food and pharmaceuticals that require high hygiene standards,pipe caps can maintain cleanliness and hygiene inside pipelines.

Welding thread flexible joint

Features:Composed of three parts:nut,cloud head,and flat joint,it has both welding firmness and easy disassembly and installation.It can be used in areas that require frequent maintenance or replacement of pipeline components.

Application scenario:At the connection between equipment and pipelines,such as the inlet and outlet of pumps,valves,etc.,flexible joints are used to facilitate the installation,debugging,and maintenance of equipment;In the connection between instruments and pipelines,flexible joints can also be used to facilitate the disassembly and calibration of instruments.
