emwa hose connectors Germany emwa model emwa price

emwa hose connectors are pipe fittings and pipeline connectors. Also known as tee fittings or three-way fittings, they are used where branch pipes diverge from the main pipeline. A tee has three openings: one inlet and two outlets, or two inlets and one outlet. It is a type of chemical pipe fitting available in T shape and Y shape, with equal-diameter or reducing ports, used at junctions where three identical or different pipelines converge. The primary function of a tee is to change the direction of fluid flow.

emwa hose connector manufacturing process

Seamless elbows: An elbow is a pipe fitting used at pipe bends. Among all pipe fittings used in piping systems, they account for the largest proportion, approximately 80%. Typically, different forming processes are selected for elbows made of different materials or wall thicknesses. Common seamless elbow forming processes used by manufacturers include hot pushing, stamping, and extrusion. Hot push forming: The hot push elbow forming process uses specialized elbow pushing machines, mandrels, and heating devices to push the blank mounted on the mold forward. During movement, it is heated, expanded, and bent into shape. The deformation characteristic of hot push elbows is based on the principle that the volume of metal remains unchanged before and after plastic deformation to determine the pipe blank diameter. The pipe blank diameter used is smaller than the elbow diameter. The mandrel controls the deformation process of the blank, causing the metal compressed at the inner arc to flow and compensate for other areas thinned due to expansion, thereby achieving uniform wall thickness. The hot push elbow forming process features an attractive appearance, uniform wall thickness, and continuous operation, making it suitable for mass production. Therefore, it has become the main forming method for carbon steel and alloy steel elbows, and is also applied in the forming of stainless steel elbows of certain specifications. Heating methods during the forming process include medium-frequency or high-frequency induction heating (heating coils can be multi-turn or single-turn), flame heating, and reverberatory furnace heating. The choice of heating method depends on product requirements and energy availability. Medium plate welding: Half of the elbow profile is formed from medium plates using a press, and then the two halves are welded together. This process is generally used for elbows larger than DN700.

emwa hose connector installation precautions

Pipe threads shall meet requirements. Threading shall be completed in two passes, using coolant during machining. Machine threads to the dimensions specified by the applicable standard. Clean chips remaining on the threads or pipe ends, and apply a rust preventive to the thread surfaces for corrosion protection and sealing. The engagement length of threaded connections shall be tightened to the proper torque using a pipe wrench at the threaded fittings of the piping components. After connecting pipes and fittings, apply rust-preventive sealant or zinc-rich paint to exposed threads, all wrench marks, and surface damage. When threaded fittings have different heights, do not install them reversed. Locking methods shall be reliable. For bolt structures subjected to bending moments, minimize thread loading to avoid bending stress on the bolts. Threaded holes shall not pass through both welded parts. For deep threaded holes, provide corresponding bosses on the part. The heads of fastening bolts for high-speed rotating bodies shall not protrude.

emwa hose connector usage

Metal hose three-column connectors are generally used to connect low-pressure air lines for air conditioners, heating systems, humidifiers, exhaust fans, etc. They are universal connectors that are easy to install and have a very stable structure. They are widely used for connecting household air lines such as home air conditioners, heating systems, household humidifiers, and exhaust fans. Metal hose three-column connectors can be applied to various indoor vertical or horizontal air ducts for air conditioners, heating systems, and humidifiers. They can connect air conditioning pipes of different diameters and are suitable for connecting air lines in indoor air conditioning systems, heating systems, household humidifiers, and exhaust fans. These connectors can be used in the installation of various indoor air conditioning systems in industrial plants, shopping malls, office buildings, and residences, facilitating the connection of air conditioning pipes and making system installation more convenient. Metal hose three-column connectors can also be applied to automotive air conditioning systems, car humidifiers, and car exhaust fans, connecting automotive air lines and simplifying the installation of car air conditioning systems. In summary, metal hose three-column connectors are widely applicable for connecting household air lines such as home air conditioners, heating systems, household humidifiers, and exhaust fans, as well as automotive air lines for car air conditioning systems, car humidifiers, and car exhaust fans, making installation more convenient.
