SUCO hose connector Germany SUCO model SUCO price

SUCO hose connectors are components used to connect water pipes. Connectors can be classified by usage method into: external thread end-connecting water pipe connectors, compression-type water pipe connectors, and self-locking water pipe connectors. External thread end-connecting water pipe connectors are die-cast from zinc alloy, with surfaces galvanized, sandblasted, or chrome-plated; they feature a compact structure, no pores, and high strength. Compression-type water pipe connectors can connect threaded-less steel pipes to hoses, eliminating the threading process; simply screw in the fastener. They have a compact structure and high strength. Water pipe connectors can connect threaded-less steel pipes or threaded-less equipment outlets to hoses, eliminating the threading process; they are die-cast from zinc alloy, with surfaces galvanized, sandblasted, or chrome-plated; they feature a compact structure and high strength. Widely used in high-end buildings, hotels, hospitals, office towers, stadiums, museums, government agencies, villas, and residential communities.

SUCO hose connector manufacturing process

Seamless elbows: An elbow is a pipe fitting used at pipe turns. Among all pipe fittings used in piping systems, it accounts for the largest proportion, approximately 80%. Typically, different forming processes are selected for elbows 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 material 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 compressed metal at the inner arc to flow and compensate for other parts thinned due to expansion, thereby achieving an elbow with 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 certain specifications of stainless steel elbows. 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 the requirements of the formed product and energy availability. Medium plate welding: Use a press to form half of the elbow profile from medium plates, then weld the two profiles together. This process is generally used for elbows above DN700.

SUCO hose connector applications

Quick connectors, also known as self-locking connectors or quick-insert sealing connectors, allow securing pipe fittings and connectors through simple operations without tightening nuts or using clamps. They can withstand higher pressures, 70Bar or even higher. Flanged pipe openings or straight round pipes in cooling water channels usually require clamps for standard connectors, involving multiple steps and offering limited pressure resistance. With technological advancements, besides self-locking quick connectors, pneumatic quick connectors (automated quick connectors) are better suited for industrial automation production, using pneumatic drive. The purpose of using quick connectors is speed; modern mechanized production emphasizes efficiency and reducing operator workload. Their speed is reflected in: easy handling, fewer steps, simple operation, automatic locking, and sealing/disconnection requiring only one plug-in and one pull-out, which is much more convenient than standard connectors.

SUCO hose connector precautions

Do not use hose quick connectors for purposes other than fluid transfer. Do not use with fluids other than the specified applicable fluids. Do not exceed the maximum operating pressure during use. Do not use outside the specified temperature range to prevent deformation of sealing materials, which can easily lead to leaks. Do not subject to artificial impact, bending, or stretching to prevent damage. Do not use in environments contaminated with metal powder or sand/dust; while quick connectors can be used in harsh conditions and ensure long service life, attachment of debris can cause malfunction or leakage. Do not disassemble the quick connector.
