ENGINEERING AUTOMATION FOR A SMARTER INDUSTRY

Household air conditioner

Pipe fittings are the core components of air conditioning refrigerant transmission and heat exchange systems, mainly used in connecting extension pipes for internal and external units, refrigerant branch pipes, U-shaped heat exchange copper pipes inside condensers/evaporators, pipeline joints, etc. Processing requires meeting high-precision expansion, bending, and welding requirements, ensuring sealing and pressure resistance, and preventing refrigerant leakage. Currently, high-precision copper pipes are commonly used for processing, and some energy-saving models are also replaced with lightweight aluminum pipes.

Car air conditioner

In addition to the high and low pressure refrigerant transmission pipelines of traditional fuel vehicles, customized fittings are also widely used in the heat pump air conditioning and battery thermal management systems of new energy vehicles. It is necessary to adapt to the compact spatial layout of the engine compartment/chassis for complex shaped bending pipe processing, while meeting the requirements of high and low temperature resistance, vibration resistance, and leakage prevention. Nowadays, lightweight aluminum tubes are commonly used for processing, combined with precise joint welding technology, to adapt to long-term vibration conditions of the entire vehicle.

Compressor

The intake, exhaust, and oil supply pipelines of various compressors (such as air conditioning compressors, air compressors, refrigeration compressors, etc.), as well as internal silencing pipes and connecting branch pipes, all rely on the processing of pipe fittings. Due to the high working pressure and strong vibration of the compressor, the requirements for the dimensional accuracy, welding strength, pressure and corrosion resistance of the pipe fittings are much higher than those in ordinary scenarios. It is necessary to strictly control the machining tolerances to avoid fatigue fracture and leakage problems during long-term operation.

Lighting

Pipe fittings play both structural support and decorative role in lighting fixtures: the lamp arms and support columns of floor lamps and pendant lamps, the frames of ceiling lamps, the lamp posts of outdoor street lamps, and the aluminum heat dissipation pipes of LED lighting fixtures all require pipe fitting processing. Many creative lighting fixtures use irregular curved pipes to achieve special design shapes, combined with surface treatments such as polishing, chrome plating, painting, sandblasting, etc., to balance structural strength and aesthetic appearance.

Furniture

Table and chair frames, table legs and chair legs, wardrobe hangers, coat racks, office furniture screen supports, shelf frames, sofa support frames, and more are often made of steel pipes, stainless steel pipes, aluminum alloy pipes, and processed through cutting, punching, bending, welding, and then treated with rust prevention, wood grain transfer printing, spraying, etc., taking into account both load-bearing requirements and aesthetics. Customized shaped pipe fittings are also widely used in creative internet famous furniture.

Bathroom

One type is functional water supply and drainage fittings, such as faucet inlet and outlet pipes, showerhead connection pipes, toilet inlet pipes, and shower column main pipes, which are required to meet drinking water hygiene standards, be resistant to rust and leakage, and often use stainless steel and copper fittings for processing, requiring processes such as tapping, polishing, and chrome plating to ensure sealing and durability; Another type is structural fittings, such as towel racks, storage racks, bathroom cabinet brackets, and overall bathroom frames, which also rely heavily on stainless steel fittings for processing and forming.
